Reversible Encoding in Spatial and Spectral Domain,sults, video steganography, dual-image steganography, and hash base steganography with adjustment procedure are given in detail. Genetic algorithm-based color image authentication technique with implementation results, analysis, and comparison of the results with existing technique is also given.

清楚说话

Discrete Fourier Transform-Based Steganography,for both 1D and 2D DFT and IDFT transform computation for confirmation of reversibility. LSB encoding on 8 x 4 sub-image is also given completely with flow diagram. A complete algorithm of DFT-based steganography is given with a capacity of embedding payload of 0.75bpB along with its implementation results and analysis.
