Data hiding is the process of embedding data into a media form such as image, voice, and video. The Lest Significant Bit (LSB) is consider as the most widely used embedding technique. LSB embeds the secret message's bits into the least significant bit plane of the image in a sequentially manner . The LSB is simple, but it poses some critical issues. The secret message is easily detected and att...

An efficient architecture of a reconfigurable Least/Most Significant Bit multiplier for Galois field where , is presented. The proposed multiplier can operate either as a most significant or as a least significant bit first multiplier. The value m, of the irreducible polynomial degree, can be changed and the value of M determines the maximum size that the multiplier can support. This architectu...

A new coding technique to be used in steganography is evaluated. The performance of this new technique is computed and comparisons with the well-known theoretical upper bound, Hamming upper bound and basic LSB are established.

Status is greatly valued in the real world, yet it has not received much attention from economic theorists. We examine how the owner of a firm can best combine money and status together to get his employees to work hard for the least total cost. We find that he should motivate workers of low skill mostly by status and high skill mostly by money. Moreover, he should do so by using a small number...

In this paper, we present a novel method to embedding secret message in the cover-image. The basic concept of the proposed method is by simple Least Significant Bit (LSB) substitution. We propose a steganography method that applies a technique to embedding a wavelet compressed secret message within the Least Significant Bit (LSB) of the cover image pixels in a specific pattern. The proposed met...

This paper proposes a novel fragile watermarking scheme with a hierarchical mechanism, in which pixel-derived and block-derived watermark data are carried by the least significant bits of all pixels. On the receiver side, after identifying the blocks containing tampered content, the watermark data hidden in the rest blocks are exploited to exactly locate the tampered pixels. Moreover, using exh...

The information-hiding ratio is a well-known metric for evaluating steganalysis performance. In this paper, we introduce a new metric of image complexity to enhance the evaluation of steganalysis performance. In addition, we also present a scheme of steganalysis of least significant bit (LSB) matching steganography, based on feature mining and pattern recognition techniques. Compared to other w...

Sterilization is a very popular word used in biomedical testing (like removal of all microorganisms on surface of an article or in fluid using appropriate chemical products). Motivated by this biological analogy, we, for the first time, introduce the concept of sterilization of an image, i.e., removing any steganographic information embedded in the image. Experimental results show that our tech...
