摘要：In this study, two techniques are introduced for imagesteganography in the spatial domain. These systems employ chaos theory to trackthe addresses of shuffled bits in steganography. The first system is based onthe well-known LSB technique, while the second system is based on a recentapproach that searches for the identical bits between the secret message andthe cover image. A modified logistic map is employed in the chaotic map togenerate integer chaotic series to extract the shuffled addresses bits. PeakSignal-to-Noise Ratio (PSNR), Mean Square Error (MSE), histogram analysis andcorrelative analysis are used for testing and evaluating the new levels ofsecurity for the proposed techniques. The results show that the proposedmethods outperform existing systems.
