Data Security Using Cryptography and Steganography

Abstract

Communication between and among individual/devices across networks, nations and around the world has become seamless as a result of the super gateway communication system; the Internet. Internet has made the world a global hamlet, thus has the ability to give every individual in the world open access to every part of the world. This open access of the Internet has made it one of the most vulnerable technologies of our time. Though policies and regulations on privacy of information ,intellectual property right, theft of information, etc have been promulgated by word communication bodies, and agencies concern in various countries, violators such as hackers, sniffers, and their other collaborators have continually been on the increase not only their number, but by the number of their attacks, ways/methods in which they attack. Different security methods have been developed to secure data from every form of attach, which ranged from transposition of text, through cryptography, to steganography. This paper discusses the design of a combination of cryptography and steganography with the aim of providing more security to data on transmission on the super-highway; the Internet.
