A Novel Technique for Steganography Method Based on Improved Genetic Algorithm Optimization in Spatial Domain
This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...
متن کاملGenetic Algorithm in Audio Steganography
-With the advancement of communication technology, data is exchanged digitally over the network. At the other side the technology is also proven as a tool for unauthorized access to attackers. Thus the security of data to be transmitted digitally should get prime focus. Data hiding is the common approach to secure data. In steganography technique, the existence of data is concealed. GA is an em...
متن کاملImproved Adaptive LSB Steganography Based on Chaos and Genetic Algorithm
We propose a novel steganographic method in JPEG images with high performance. Firstly, we propose improved adaptive LSB steganography, which can achieve high capacity while preserving the first-order statistics. Secondly, in order to minimize visual degradation of the stego image, we shuffle bits-order of the message based on chaos whose parameters are selected by the genetic algorithm. Shuffl...
متن کاملA Secure Steganography Method based on Genetic Algorithm
With the extensive application of steganography, it is challenged by steganalysis. The most notable steganalysis algorithm is the RS attack which detects the steg-message by the statistic analysis of pixel values. To ensure the security against the RS analysis, we presents a new steganography based on genetic algorithm in this paper. After embedding the secret message in LSB (least significant ...
متن کاملA Report on Genetic Algorithm based Steganography for Image Authentication
Image authentication is done by embedding image/ message in spatial domain or frequency domain. A mask is chosen from the source image in row major order. Bits of the authenticating image are embedded in each byte of the source image block where the position is chosen using hash function. A hash function is a function that takes variable size inputs and return fixed size output. The position wi...
