In this paper, we present an efficient scheme of color image steganography based on Mix Column Transform (MCT) on specified blocks selected according to secret key and hide the secret message within those using logical X-OR operation. Our experiments show that the security can be increased by following this method since it uses irreducible polynomial mathematics within its operational method. The...
DNA computing or well known as molecular computing is computing technique using DNA molecule to store information and using biochemistry operation as computational tool to manipulate string in DNA strand to produce the result. Lipton point out massive parallelism and storage capacity make this convenient to solve combinatorial problems. In this paper we proposed DNA based computer to solve vertex...
Children with Dyslexia are having language learning disorder and makes them difficult mastering the skill to read, spell and write. Although their cognitive capability is adequate, they faced difficulty in learning to read via conventional instruction approach. This paper presents a mobile application known as 'Dyslexia Baca' specifically developed to help dyslexic children to recognize and distinguish...
This paper explored the impact of legibility on full high definition (Full-HD) liquid crystal display (LCD) for video display terminal (VDT). A total of 117 participants were tested for legibility of 13 colour combinations based on more than 90- year-old Le Courier Table of Legibility. The participants first completed a survey online, then they were presented to a text designed using Wilkins Rate...
