Digital Image Hiding Technology Based on Chaotic Encryption and Adaptive Blending
Xiao-Hui Yuan · Tv Engineering · 2004
Based on the analysis of traditional information encryption methods, this paper first discusses image encryption by using changed Logistic system and then describes chaotic image encryption by means of the primary parameters formed by the password. General methods for hiding blended images are described, and an adaptive blending algorithm is put forward in allusion to the difficulty in the selection of blending parameters. Finally, hiding algorithm of adaptive blending image is used for hiding processing of the encrypted image information. Experiments show that this algorithm is simple, safe and robust, and eliminates the fault in which the confidential image outline always emerges on the resulting image.
