A Novel Algorithm In Steganography Using Weighted Matching Technique

Abstract

In recent years, the security related to data over the internet has become a major issue. Different techniques are used to secure the information, one such technique is steganography. In steganography, one can have a cover media as an image, video or audio. Here we are proposing a method of weighted matching technique in which we examine higher bits of lower nibble of a byte and find the highest occurrence bit. The PSNR values of both the algorithms are tabulated for evaluation purpose.
