Modern age is a digital age. Digitalization is improving the things in all sectors. In electronics digital instruments are replacing conventional analog instruments giving precession and accuracy. Teaching learning methods are greatly improved due to incorporation of digital technology. Life style of common people is also changing due to digital tranjections, online shopping, online banking etc. The field of art and painting is also influenced by digital techniques available now a day. With emergence of new tools and techniques the art of painting is gaining new shapes. Digital technical skills provide a wide platform for imagination of artists. There are pros and cons of each aspects but it is true that art always connect students with their own culture as well as with the wider world. Visual art always improve learners critical thinking.

More the development of the multimedia, more the digitalization, the more is the access to internet. This fast rate of enhancement gives a sense of protection and authentication.Â Digital watermarking technology provides a strong solution to insecurity created by digitalization. In this paper, our focus is on the basic concepts of watermarking, their characterisation, their techniques. Extending more, we will elaborate one of the latest technique of watermarking named as â€œDiscrete Cosine Transformâ€ (DCT).

In this research, a comparison of the various techniques used for face recognition is shown in tabular format to give a precise overview of what different authors have already projected in this particular field. A systematic review of 40 journal articles pertaining to feature dimensionality reduction was carried out. The articles were reviewed to appraise the methodology and to identify the key parameters that were used for testing and evaluation. The dates of publication of the articles were between 2007 and 2015. Ten percent (10%) of the articles reported the training time for their system while twenty four percent (24%) reported their testing time. Sixty seven percent (67%) of the reviewed articles reported the image dimension used in the research. Also, only fourty eight percent (48%) of the reviewed articles compared their result with other existing methods. The main emphasis of this survey is to identify the major trade-offs of parameters and (or) metrics for evaluating the performance of the techniques employed in dimensionality reduction by existing face recognition systems. Findings from the review carried out showed that major performance metrics reported by vast amount of researchers in this review is recognition accuracy in which eighty six percent (86%) of the authors reported in their experiment.

Sensitive data is constantly being transmitted particularly over wireless communication systems due to how convenient this wireless communication systems are. However, these communication systems are generally weak in terms of privacy protection and security as a whole. This is because anyone within the perimeter of a wireless network can attempt hacking into the network without physically connecting to it. This paper will focus on the two most common data security techniques in wireless communication systems – steganography and cryptography. Steganography is the practice of hiding information in another message or physical item such that its presence cannot be detected by human examination. Cryptography on the other hand is the science of encrypting information in a way that unintended recipients cannot interpret and then decrypting the said message back into plaintext. Keywords: Cryptography, Data Encryption, Data Decryption, Steganography, Wireless Communication

ABSTRACT This study compared four different transformation techniques by applying a simple linear regression on raw and transformed data. The R2 of each model was obtained and a test on the significance of these R2 was carried out. Also, the rxy(coefficient of correlation) were also obtained. The data used is a secondary data consisting of 53years (1964-2016) of the infant mortality rate in Nigeria (https://www.ceicdata.com/en/nigeria/health-statistics/ng-mortality-rate-infant-per-1000-live-births). The rxy were also compared and the results, 95.8%, 95.8%, 96.2%, 93.0%, and 92.9% respectively. The R2 obtained for the raw data, logarithm, square-root, square and inverse are as follows: 91.8%, 91.7%, 92.5%, 86.6% and 86.4% respectively. However, the R2 obtained for the raw data, logarithm, square-root, square and inverse compete favourably but the performance of inverse transformation suits the data most in terms of model accuracy. Key Words: Transformation, Raw data, logarithm, square-root, square, inverse

Embedding a hidden stream of bits in a file is called Digital watermarking. The file could be an image, audio, video or text. Nowadays, a digital watermarking has many applications such as broadcast monitoring, owner identification, proof of ownership, transaction tracking, content authentication, copy control, device control and file reconstruction. It is intended to complement cryptographic processes. It is a visible or preferably invisible, identification code that is permanently embedded in the data and remains present within the data after any decryption process. The focus of this paper will detail digital watermarking for multimedia applications and covered by definition of digital watermarking, purpose, techniques and types of watermarking attacks briefly discussed.

Resumo:

This article examines the role cryptographic methods play in protecting digital assets through blockchain systems, with a particular focus on their adjustment to contemporary challenges and technological trends. An endeavor is undertaken to systematize major cryptographic algorithms, their effective appraisal in data protection, and development prospects under quantum computing threats. The study is relevant because centralized systems increasingly depend on cryptography due to greater regulatory pressures and, above all, a need for security through secrecy. The scientific novelty lies in the detailed comparative analysis of the said methodology (hashing, digital signatures, zero-knowledge proofs) for cases relating to major blockchain platforms (Bitcoin, Ethereum, Zcash), which hence demonstrate varied approaches towards security provision. The study's methodological foundation consists of analyzing 13 sources, merging a qualitative examination of algorithms and ECDSA with zk-SNARKs with a quantitative assessment of their effectiveness. Hash functions and Merkle trees ensure data integrity while reducing the computational costs of verification; asymmetric cryptography and Zero-Knowledge Proofs guarantee authenticity and confidentiality for the function of the transaction. Main findings support that cryptography is the cornerstone technology for blockchain security, but it has to be tailored to meet new challenges. Development in post-quantum algorithms and the infusion of homomorphic encryption will soon become imperative for quantum threats. This paper strongly advocates hybrid solutions that would bring traditional ways merged with novelties, which will provide sustainability over time for digital assets. Thus, this article will be useful for Developers of Blockchain Systems, Cryptographers, Cybersecurity Experts, & Regulators willing to know how protection methods for digital assets evolve.
