LSB Color Image Embedding Steganography Based on Cyclic Chaos

摘要

Image steganography is a technique for hiding secret data in cover image. In recent years, chaotic systems have become increasingly important in steganography. This paper proposes an embedding technique based on cyclic chaos, which effectively embeds secret messages into color images. The cyclic chaos is divided into two parts: the chaotic function of generating seeds and the pseudo random number generator (PRNG). A pixel is found through the chaotic cycle system, and a three-bit secret message is embedded into the R, G, and B channels of the pixel through a specific embedding algorithm. Compared with other color image embedding methods, the proposed algorithm has higher visual quality and improved security.
