The enormous growth in the size of scholarly literature makes its retrieval challenging. To address this challenge, researchers and practitioners developed several solutions. These include indexing solutions e.g. ResearchGate, Directory of Open Access Journals (DOAJ), Digital Bibliography & Library Project (DBLP) etc., research paper repositories e.g. arXiv.org, Zenodo, etc., digital libraries, scholarly retrieval systems, e.g., Google Scholar, Microsoft Academic Search, Semantic Scholar etc., digital libraries, and publisher websites. Among these, the scholarly retrieval systems, the main focus of this article, employ efficient information retrieval techniques and other search tactics. However, they are still limited in meeting the user information needs to the fullest. This brief review paper is an attempt to identify the main reasons behind this failure by reporting the current state of scholarly retrieval systems. The findings of this study suggest that the existing scholarly retrieval systems should differentiate scholarly users from ordinary users and identify their needs. Citation network analysis should be made an essential part of the retrieval system to improve the search precision and accuracy. The paper also identifies several research challenges and opportunities that may lead to better scholarly retrieval systems.

Purpose The purpose of this study is to investigate the use of integrated library system (ILS) in academic library operations in Edo and Delta states, Nigeria. Design/methodology/approach This study adopted a descriptive survey research design. Total enumeration was used since the population consisting 88 academic librarians in Edo and Delta states is not large and was considered appropriate to achieve the purpose of this study. Questionnaire titled “Assessment of adoption and use of Integrated Library Software (ILS) for library service provision in academic libraries in Edo and Delta States, Nigeria” was used. Before the administration of the questionnaire on the respondents, face validity was carried out to test the validity of the questions. The questionnaire was given to experts in the Department of Information Resources Management, Babcock University, Ilishan-Remo, Ogun State who validated, resolved defects and modified the questionnaire. Findings This study showed that there is a general non-use of ILS in academic libraries in Delta state. Findings revealed that three of the four academic libraries in Edo State adopted library software in their library operations except Ambrose Ali University Library, Ekpoma. Findings further showed that the ILS that were used in academic libraries in Edo State are effective. It also revealed that ILS is effective for accessing books and other library materials, retrieval of materials, bibliographic search and provision of links to external databases. Finding also indicated that among the library software that were used in academic libraries in this study, only Koha ILS has the capacity to link to external databases. Practical implications The use of ILS in academic library operation is critical. Its adoption and use to a large extent positively affect the library and its users. Non-adoption and use of ILS in most academic libraries is a setback to delivery of quality library services to clientele. Originality/value This study is the first that assessed the adoption and use of ILS in academic libraries is Edo and Delta states. It exposed the level of adoption and utilization of ILS in library operations with a view to encouraging libraries to adopt and use ILS for library services.

Advances in information storage and image acquisition technologies have enabled the creation of enormous image datasets. during this situation, it's necessary to develop applicable data systems to with efficiency manage these collections. the most typical approaches use the supposed Content-Based Image Retrieval (CBIR) systems. Basically, these systems attempt to retrieve pictures like a user-defined specification or pattern (e.g., form sketch, image example). Their goal is to support image retrieval supported content properties (e.g., shape, color, texture), typically encoded into feature vectors. one among the most benefits of the CBIR approach is that the chance of AN automatic retrieval method, rather than the standard keyword-based approach, thattypically needs terribly toilsome and long previous annotation of info pictures. The CBIR technology has been utilized in many applications like fingerprint identification, variety data systems, digital libraries, crime bar, medicine, historical analysis, among others.

Purpose – The purpose of this paper is to use cloud storage in digital preservation by analyzing the pricing and data retrieval models. The author recommends strategies to minimize the costs and believes cloud storage is worthy of serious consideration. Design/methodology/approach – Few articles have been published to show the uses of cloud storage in libraries. The cost is the main concern. An overview of cloud storage pricing shows a price drop once every one or one-and-a-half years. The author emphasize the data transfer-out costs and demonstrate a case study. Comparisons and analysis of S3 and Glacier have been conducted to show the differences in retrieval and costs. Findings – Cloud storage solutions like Glacier can be very attractive for long-term digital preservation if data can be operated within the provider’s same data zone and data transfer-out can be minimized. Practical implications – Institutions can benefit from cloud storage by understanding the cost models and data retrieval models. Multiple strategies are suggested to minimize the costs. Originality/value – The paper is intended to bridge the gap of uses of cloud storage. Cloud storage pricing especially data transfer-out pricing charts are presented to show the price drops over the past eight years. Costs and analysis of storing and retrieving data in Amazon S3 and Glacier are discussed in details. Comparisons of S3 and Glacier show that Glacier has uniqueness and advantages over other cloud storage solutions. Finally strategies are suggested to minimize the costs of using cloud storage. The analysis shows that cloud storage can be very useful in digital preservation.

Thesis (MPhil)--Stellenbosch University, 2013.ENGLISH ABSTRACT: This thesis investigates the complexities involved in Health Information Systems. The focus is on the factors of a) efficiency and b) usability. A case study is made of a recently implemented system in Charlotte Maxeke Johannesburg Academic hospital. The first objective of the research was to gain a deeper understanding of the complexities of Health Information Systems, and secondly to evaluate the situation at Charlotte Maxeke Johannesburg Academic Hospital. In Chapter 1 a detailed introduction of the thesis is offered. This includes, explaining what triggered the research, the objective of the research and the methodology used to conduct the research. In Chapter 2 the focus is on a literature review of Health Information Systems, system fundamentals and planning and implementation. It is clear that without a methodology, systems development becomes haphazard and subsequently a risky and expensive undertaking. While change is pervasive, introducing operational efficiencies sometimes may necessitate reviewing of information systems and business strategy, knowledge management and process orientation. In Chapter 3 the issue of usability is investigated. Several healthcare institutions have implemented information systems but evaluations of the usability of these systems are still under debate. For purposes of this research an evaluation method for system usability and survey questionnaires were developed. In Chapter 4 the case study of Charlotte Maxeke Johannesburg Academic Hospital is reported. The chapter also describes the data collection design, research limitations and delimitations, survey findings and interpretations. In Chapter 5 the implications and applications of Health Information Systems are discussed. After analysis of the survey results, it appears that the impact and benefits of the new Health Information System are only positive or realized in the patient administration division. The rest of the health professionals continue to manually capture clinical notes and other management information on pieces of papers, spread sheets and word documents. The thesis comes to the conclusion that despite widespread use of technology in other sectors, clinicians in hospitals do not use implemented automated systems. Implementation of systems is complex and problems associated with usability are not resolved and that traditional systems implementation methodologies may not apply.
AFRIKAANSE OPSOMMING: Die tesis ondersoek die faktore wat Gesondheidstelsels (HIC) ingewikkeld maak. Die fokus is op a) doeltreffendheid, en b) bruikbaarheid (uit gebruikersoogpunt). ‘n Gevallestudie word gemaak van ‘n stelsel wat onlangs by Chalotte Maxeke Johannesburg Akakdemiese Hospitaal in gebruik geneem is. Die eerste doelwit van die ondersoek was om die ingewikkeldheidsgraad van sodanige stelsels te probeer bepaal, en tweedens om die situasie in die hospitaal self te evalueer. In hoofstauk 1 word die agtergond en aanleiding tot die ondersoek uiteengesite, woel as die metodologiese keuses wat gemaak is. Hoofstuk 2 bied ‘n oorsig oor relevante literatuur ten ospigte van HIC. Dit is duidelik stlselontwikkeling riskant, onnodig duur en koersloos is as dit sonder ‘n duidelike metodologie geïmplementeer word. Verandering vind voortdurend plaas en die implementering van oprasionele doeltreffendheid mag vernadering in besigheidstrategie, informasiestelsels, kennisbestuur en processoriëntasie noodsaaklik maak. In hoofstuk 3 word bruikbaarheid ondersoek. Verskeie mediese instellings het soortgelyke stelsels in gebruik geneem, maar die bruikbaarheid daarvan is steeds onseker. Vir die doeleindes van hierdie tesis is ‘n eie evaluasiemetode ontwikkel en ‘n vraelys op grond daarvan opgestel. Hoofstuk 4 rapporteer die gevallestudie in Charlotte Maxeke Johannesburg Akademiese Horspitaal hospital. Datakolleksie, navorsingsafbakening en – beperkinge, sowel as vraelysresultate word aangebied. Hoofstuk 5 bespreek die implikasies en toepassings van HIC. Dit blyk dat die voordele van die stelsel slegs deur die pasiëntadministrasieafdeling geniet word. Alle ander afdeling gaan steeds voort met papiergebaseerde inligtingstelsels, aangevaul deur ad hoc gebruik van Excel en woordprossering. Die tesis kom tot die gevolgtrekking dat kliniese personeel avers is teen die gebruik van geoutomatiseerde informasiestelsels.

Automatic music genre classi cation is a high-level task in the eld of Music Information
Retrieval (MIR). It refers to the process of automatically assigning genre labels to music
for various tasks, including, but not limited to categorization, organization and browsing.
This is a topic which has seen an increase in interest recently as one of the cornerstones of
MIR. However, due to the subjective and ambiguous nature of music, traditional single-label
classi cation is inadequate.
In this thesis, we study multi-label music genre classi cation from perceptual and computational
perspectives. First, we design a set of perceptual experiments to investigate
the genre-labelling behavior of individuals. The results from these experiments lead us to
speculate that multi-label classi cation is more appropriate for classifying music genres.
Second, we design a set of computational experiments to evaluate multi-label classi cation
algorithms on music. These experiments not only support our speculation but also reveal
which algorithms are more suitable for music genre classi cation. Finally, we propose and
examine a group of ensemble approaches for combining multi-label classi cation algorithms
to further improve classi cation performance.

University of Central Florida College of Engineering ThesisThere is a great need to automatically segment, categorize, and annotate video data, and to develop efficient tools for browsing and searching. We believe that the categorization of videos can be achieved by exploring the concepts and meanings of the videos. This task requires bridging the gap between low-level content and high-level concepts (or semantics). Once a relationship is established between the low-level computable features of the video and its semantics, .the user would be able to navigate through videos through the use of concepts and ideas (for example, a user could extract only those scenes in an action film that actually contain fights) rat her than sequentially browsing the whole video. However, this relationship must follow the norms of human perception and abide by the rules that are most often followed by the creators (directors) of these videos. These rules are called film grammar in video production literature. Like any natural language, this grammar has several dialects, but it has been acknowledged to be universal. Therefore, the knowledge of film grammar can be exploited effectively for the understanding of films. To interpret an idea using the grammar, we need to first understand the symbols, as in natural languages, and second, understand the rules of combination of these symbols to represent concepts. In order to develop algorithms that exploit this film grammar, it is necessary to relate the symbols of the grammar to computable video features.

The purpose of this study was to examine whether or not DCS social workers would obtain client's educational records if they had electronic access to these records. If a social worker could access client school records quickly and easily and then enter the information into the case management computer system, the school history would travel with the client to their new environment. This information would insure that the foster child with special education needs was placed in the proper classroom, giving the child a better chance to succeed.

Resumo: Informação geográfica é usualmente encontrada em objetos digitais (como documentos, imagens e vídeos), sendo de grande interesse utilizá-la na implementação de diferentes serviços. Por exemplo, serviços de navegação baseados em mapas e buscas geográficas podem se beneficiar das localizações geográficas associadas a objetos digitais. A implementação destes serviços, no entanto, demanda o uso de coleções de dados geocodificados. Este trabalho estuda a combinação de conteúdo textual e visual para geocodificar objetos digitais e propõe um arcabouço de agregação de listas para geocodificação multimodal. A informação textual e visual de vídeos e imagens é usada para definir listas ordenadas. Em seguida, elas são combinadas e a nova lista ordenada resultante é usada para definir a localização geográfica de vídeos e imagens. Uma arquitetura que implementa essa proposta foi projetada de modo que módulos específicos para cada modalidade (e.g., textual ou visual) possam ser aperfeiçoados independentemente. Outro componente é o módulo de fusão responsável pela combinação das listas ordenadas definidas por cada modalidade. Outra contribuição deste trabalho é a proposta de uma nova medida de avaliação da efetividade de métodos de geocodificação chamada Weighted Average Score (WAS). Ela é baseada em ponderações de distâncias que permitem avaliar a efetividade de uma abordagem, considerando todos os resultados de geocodificação das amostras de teste. O arcabouço proposto foi validado em dois contextos: desafio Placing Task da iniciativa MediaEval 2012, que consiste em atribuir, automaticamente, coordenadas geográficas a vídeos; e geocodificação de fotos de prédios da Virginia Tech (VT) nos EUA. No contexto do desafio Placing Task, os resultados mostram como nossa abordagem melhora a geocodificação em comparação a métodos que apenas contam com uma modalidade (sejam descritores textuais ou visuais). Nós mostramos ainda que a proposta multimodal produziu resultados comparáveis às melhores submissões que também não usavam informações adicionais além daquelas disponibilizadas na base de treinamento. Em relação à geocodificação das fotos de prédios da VT, os experimentos demostraram que alguns dos descritores visuais locais produziram resultados efetivos. A seleção desses descritores e sua combinação melhoraram esses resultados quando a base de conhecimento tinha as mesmas características da base de teste
Abstract: Geographical information is often enclosed in digital objects (like documents, images, and videos) and its use to support the implementation of different services is of great interest. For example, the implementation of map-based browser services and geographic searches may take advantage of geographic locations associated with digital objects. The implementation of such services, however, demands the use of geocoded data collections. This work investigates the combination of textual and visual content to geocode digital objects and proposes a rank aggregation framework for multimodal geocoding. Textual and visual information associated with videos and images are used to define ranked lists. These lists are later combined, and the new resulting ranked list is used to define appropriate locations. An architecture that implements the proposed framework is designed in such a way that specific modules for each modality (e.g., textual and visual) can be developed and evolved independently. Another component is a data fusion module responsible for combining seamlessly the ranked lists defined for each modality. Another contribution of this work is related to the proposal of a new effectiveness evaluation measure named Weighted Average Score (WAS). The proposed measure is based on distance scores that are combined to assess how effective a designed/tested approach is, considering its overall geocoding results for a given test dataset. We validate the proposed framework in two contexts: the MediaEval 2012 Placing Task, whose objective is to automatically assign geographical coordinates to videos; and the task of geocoding photos of buildings from Virginia Tech (VT), USA. In the context of Placing Task, obtained results show how our multimodal approach improves the geocoding results when compared to methods that rely on a single modality (either textual or visual descriptors). We also show that the proposed multimodal approach yields comparable results to the best submissions to the Placing Task in 2012 using no additional information besides the available development/training data. In the context of the task of geocoding VT building photos, performed experiments demonstrate that some of the evaluated local descriptors yield effective results. The descriptor selection criteria and their combination improved the results when the used knowledge base has the same characteristics of the test set

Thesis submitted in fulfilment of the requirements for the degree
Master of Technology (MTech) in Information Technology
In the Faculty of Informatics and Design,
at the Cape Peninsula University of Technology (CPUT), 2013Healthcare services are vital to all human beings, as our daily lives depend on them. In South Africa approximately eighty per cent of the population uses the public healthcare services. In the current healthcare systems data corruption exists which threatens data quality in the systems. The aim of this study was to understand the existing information handling processes and factors that affect the accuracy and integrity of healthcare data. A qualitative research methodology, under the interpretive paradigm was used for this investigation. Activity theory is used to formulate an analytical framework, the “healthcare information system data quality activity theory framework”. This was very helpful for understanding the healthcare information handling process as an activity system that consists of actors with individual goals. Though the goals are varied, they are joined together by the common objective. The logic of the framework is that a realisation of goals in the activity system depends on a number of factors. At the beginning, there must be a synchronous inter-linkage between the goals of the actors, the mediating factors such as adequate tools, user skills, enabling policies, and the systematic procedures that are diligently enforced. It is assumed that any situation which prevents this inter-linkage will have a negative impact on the realisation of the sought objective. The framework therefore, was very helpful in informing questions, the data collection and ultimately, the analysis processes. The public healthcare sector is the main source of data; other sources were literature, the Internet and books. The analysis of data was done using content analysis to find what themes emerge and the relationship (s) between them in what is being analysed. The findings reveal a lack of adherence to information handling procedures and processes which lead to corrupt data in the systems. In addition, most users have limited skills, which is a hindrance to them in performing their duties as expected by the healthcare sector. In fact, the healthcare sector is also challenged by systems which are constantly slow or down, due to limited network capacity and human errors. The presence of these challenges suggests non-adherence to data handling procedures, which explains the existing corrupt data in the healthcare systems. Therefore the recommendation is that the public healthcare administration must enhance their training programs. The training must be re-designed to cater for the needs of all users, regardless of their background. It needs to improve user skills and boast their confidence in using electronic systems. Obviously, any changes and improvements need to be sustainable, and the sector is unlikely to succeed without enforcement of new procedures. Therefore, adherence to data handling procedures must be strictly enforced, with policies thoroughly communicated to the users. That way, the sector will not only have systems and related policies, but also ensure their full exploitation for improved service delivery in the public healthcare sector in South Africa.

In this study, a computer simulation model for library CD-ROM LAN systems was created. Using this model, the system optimization problems were examined. The simulation model imitated the process of the actual decision variables changing their values and generated the corresponding results. Under a certain system environment, if the values of decision variables are changing, the system performances are getting changed also. This study investigated these relationships with the created model. The system users' interarrival time, service time, and other relevant data were collected on randomly selected days in a university library. For data collection, both of the observation and the system automatic metering software were used. According to the collected data, a discrete events simulation model was created with GPSS/H. The simulation model was proven valid and accurate by a pilot test and by the calculation with queuing theory. Statistical tests were used for data comparison and analysis. In addition, animation technique was used to show the simulation process by using Proof Animation. By this technique, the simulation process was monitored on the screen.

Digital libraries remove physical barriers to accessing information, but the language barrier still remains due to multilingual collections and the linguistic diversity of users. This study aims at understanding the effect of users’ language skills and field of knowledge on their language preferences when searching for information online and to provide new insights on the access to multilingual digital libraries. Both quantitative and qualitative data were gathered using a questionnaire and results show that the language skills and the field of knowledge have an impact on the language choice for searching online. These factors also determine the interest in cross-language information retrieval: language-related fields constitute the best potential group of users, followed by the Arts and Humanities and the Social Sciences.

The rapid development of Information and Communication Technologies (ICTs) and the advent of the World Wide Web (WWW) in the 1990s and universally centralized digital media for information storage, organization, retrieval, and management have led to the emergence of the Digital Library, which, while not replacing the traditional library per se, has contributed to the creation of hybrid forms combining the characteristics and organizational structure of both the digital and the traditional library models. This chapter draws on existing literature to highlight the potential opportunities, which digital libraries offer to the countries of the Arab world, and to examine the challenges inherent in their development and how these might best be overcome. The chapter concludes that libraries in many Arab countries are still hindered by a severe lack of resources, trained and experienced staff, and adequate infrastructure, and these problems could severely undermine attempts to move towards digitizing libraries. It is the role of the governments of these countries, along with commercial organizations, information professionals, academic specialists, and other groups to acknowledge the benefits and opportunities offered by digital libraries and work together to make them a reality in the Arab world.

Scholarly digital libraries increasingly provide analytics to information within documents themselves. This includes information about the logical document structure of use to downstream components, such as search, navigation, and summarization. In this paper, the authors describe SectLabel, a module that further develops existing software to detect the logical structure of a document from existing PDF files, using the formalism of conditional random fields. While previous work has assumed access only to the raw text representation of the document, a key aspect of this work is to integrate the use of a richer representation of the document that includes features from optical character recognition (OCR), such as font size and text position. Experiments reveal that using such rich features improves logical structure detection by a significant 9 F1 points, over a suitable baseline, motivating the use of richer document representations in other digital library applications.

This chapter studies the relevance of the feedback mechanism on the library database in academic libraries. The study is a systematic literature review which uses Kitchenham and Charters methodology. The chapter has three objectives, which are to enumerate the concept of information retrieval and its problems and the relevance of feedback mechanism to the database in academic libraries. The findings indicated that feedback is very important in the information retrieval systems most especially in relation to the database in an academic library. The contributions of this chapter show that the feedback mechanism is relevant to information retrieval. It also creates awareness among librarians of the importance of these mechanisms and encouraged them to seek for a database with these components whenever they want to buy a new database for their various institutions. The chapter, however, recommends further empirical studies on the subject matter.

From late 1990s to early 2000s, the availability of powerful computing capability, large storage devices, high-speed networking, and especially the advent of the Internet, led to a phenomenal growth of digital multimedia content in terms of size, diversity, and impact. As suggested by its name, “multimedia” is a name given to a collection of data of multiple types, which include not only “traditional multimedia” such as images and videos, but also emerging media such as 3D graphics (like VRML objects) and Web animations (like Flash animations). Furthermore, relevant techniques have been developed for a growing number of applications, ranging from document editing software to digital libraries and many Web applications. For example, most people who have used Microsoft Word have tried to insert pictures and diagrams into their documents, and they have the experience of watching online video clips such as movie trailers from Web sites such as YouTube.com. Multimedia data have been available in every corner of the digital world. With the huge volume of multimedia data, finding and accessing the multimedia documents that satisfy people’s needs in an accurate and efficient manner becomes a nontrivial problem. This problem is referred to as multimedia information retrieval. The core of multimedia information retrieval is to compute the degree of relevance between users’ information needs and multimedia data. A user’s information need is expressed as a query, which can be in various forms such as a line of free text like “Find me the photos of George Washington,” a few keywords like “George Washington photo,” a media object like a sample picture of George Washington, or their combinations. On the other hand, multimedia data are represented using a certain form of summarization, typically called index, which is directly matched against queries. Similar to a query, the index can take a variety of forms, including keywords, visual features such as color histogram and motion vector, depending on the data and task characteristics. For textual documents, mature information retrieval (IR) technologies have been developed and successfully applied in commercial systems such as Web search engines. In comparison, the research on multimedia retrieval is still in its early stage. Unlike textual data, which can be well represented by term vectors that are descriptive of data semantics, multimedia data lack an effective, semantic-level representation that can be computed automatically, which makes multimedia retrieval a much harder research problem. On the other hand, the diversity and complexity of multimedia data offer new opportunities for the retrieval task to be leveraged by the techniques in other research areas. In fact, research on multimedia retrieval has been initiated and investigated by researchers from areas of multimedia database, computer vision, natural language processing, human-computer interaction, and so forth. Overall, it is currently a very active research area that has many interactions with other areas. In the coming sections, we will overview the techniques for multimedia information retrieval, followed by a review on the applications and challenges in this area. Then, the future trends will be discussed, and some important terms in this area are defined at the end of this chapter.

Document description and coding are key operations to information storage and retrieval systems. Description makes it possible for users to obtain information about the documents while coding provides unique numbers to described documents, and enables users to locate, retrieve and store documents manually or electronically. Consequent upon the mass production of information and attendant information explosion, modern libraries and other information dissemination institutions, attached to various institutions, were established. A need therefore arose to put in place systems of achieving bibliographic control over the information produced and collected to facilitate its identification and location wherever it may be found. Among the major systems or tools that information professionals developed to achieve bibliographic control and organization of information include: cataloguing, classification, indexing and abstracting. Using largely documentary sources, the chapter makes a case on the critical role of document description and coding systems in information and knowledge management.

There are many steps involved with securing a cloud system and its applications (SaaS) and developed ones in (PaaS). Security and privacy issues represent the biggest concerns to moving services to external clouds (Public). With cloud computing, data are stored and delivered across the Internet. The owner of the data does not have control or even know where their data are being stored. Additionally, in a multi-tenant environment, it may be very difficult for a cloud service provider to provide the level of isolation and associated guarantees that are possible with an environment dedicated to a single customer. Unfortunately, to develop a security algorithm that outlines and maps out the enforcement of a security policy and procedure can be a daunting task. A good security algorithm presents a strategy to counter the vulnerabilities in a cloud system. This chapter covers the complete overview, comparative analysis of security methods in Cloud Applications in STEM Education and the introduction of a new methodology that will enforce cloud computing security against breaches and intrusions. Much light will be shed on existing methodologies of security on servers used for cloud applications in STEM education and storage of data, and several methods will be presented in addition to the newly developed method of security in cloud-based servers, such as the MIST (Alkadi). Not only can cloud networks be used to gather sensitive information on multiple platforms, also there are needs to prevent common attacks through weak password recovery, retrieval, authentication, and hardening systems; otherwise hackers will spread cyber mayhem. Discussion of current security issues and algorithms in a real world will be presented. Different technologies are being created and in constant competition to meet the demands of users who are generally “busy”. The selling point of these technologies is the ability to address these demands without adding more to any workloads. One of the demands often discussed is that users want to have their digital information accessible from anywhere at any time. This information includes documents, audio libraries, and more. Users also demand the ability to manage, edit and update this information regardless of physical location. Somewhat recently, mobile devices such as laptops, tablets, and smartphones have provided these abilities. This is no small feat as vendors and providers have reduced the size of these devices to increase mobility. However, as the amount of personal information that users are wanting to access has grown exponentially, manipulation and storage of it require more capable devices. To meet increased demands, increasing the capabilities of mobile devices may be impractical. Making mobile devices more powerful without technological advancement would require that the device be larger and use more resources such as battery life and processing power to function properly. Storing all of a user's information on a mobile device that travels everywhere also adds vulnerability risks. The best technical solution to having a user's information accessible is some sort of online storage where there is the convenience to store, manipulate and retrieve data. This is one of the most practical applications for the concept of cloud computing in STEM education. As storage capabilities and Internet bandwidth has increased, so has the amount of personal data that users store online. And today, the average user has billions of bytes of data online. Access is everywhere and whenever is needed. As everyone started doing so, people want their data safe and secure to maintain their privacy. As the user base grew in size, the number of security issues of the personal data started to become increasingly important. As soon as someone's data are in the remote server, unwanted users or “hackers” can have many opportunities to compromise the data. As the online server needs to be up and running all the time, the only way to secure the cloud server is by using better passwords by every user. By the same token, the flaws in the password authentication and protection system can also help unwanted users to get their way to other people's personal data. Thus, the password authentication system should also be free from any loopholes and vulnerabilities.
