Modified and Highly Enhanced Matrix Approach Method of Steganography

Abstract

Data security is a major threat in every field today. Data security can be provided in several ways, but one of the most common disadvantages is that it is highly difficult to retrieve the message unless the encoded key is known. Also these algorithms reveal the existence of message; although the message is encoded, and so reliability on these algorithms is of no use. One approach to overcome most of these drawbacks is to use Steganographic techniques. Steganography process hides the data in multimedia file so that no one knows the existence of hidden data except the sender and receiver. This paper presents a highly enhanced matrix approach algorithm through which a large amount of data can be hidden inside an image file. This algorithm ensures the security and safety of hidden data. Thus the algorithm can be extended to the fields of Defence, Internet and other applications where data security is of primary concern.
