Data Hiding System Using Cryptography & Steganography: A Comprehensive Modern Investigation

In excess of the past few decades with progression in era of information society, computer networks and their related applications are becoming more and more popular. As the use of internet and reliance on the world wide system growing rapidly in daily life increase the number of networked machines which have leads unauthorized activity not only from external attackers, but also from internal attackers, such as disgruntled employees and people abusing their privileges for personal gain. The precious information is always prone to maximum attacks over the network. Attacks may occur due to system vulnerabilities or security breaches, such as system misconfiguration, user misuse or program defects. Attackers can also combine multiple security vulnerabilities into an intelligent attacking system. Therefore, an efficient security model is needed to defense secrete information over the network system. However, a number of approaches have been proposed in context to enhance the security of secrete information but each of them has its own limitation. These limitations represent problem with the current security systems and have led to an increasing interest in design and implementation of an efficient method to secure the secrete information. This paper presents a comprehensive investigation of two popular security techniques, cryptography and steganography, which performs better in comparison of other existing standard and automated security methods.
