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 cove 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 number of changes of lsb values. his method verifiably reduces the probability of detection and also improves the visual quality of stego images. however, his method still has room for improvement. in this paper, a dual-state scoring model, structured upon genetic algorithm is presented which assesses the performance of different orders for lsb matching and searches for a near-optimum solution among all the permutation orders. experimental results confirm the superiority of the new approach compared to the mielikainen’s pair-wise lsb matching scheme in terms of distortion.
