A novel color image steganography algorithm based on bit counting and multiple-base system

Abstract

This paper proposes a novel color image steganography scheme using a compound sinusoidal discrete memristor map and bit counting method. Firstly, a new 2D compound sinusoidal discrete memristor map is designed to generate chaotic sequences with good randomness. Secondly, a new steganography algorithm combining bit counting and multiple-base system is proposed to reduce the distortion of the stego image. Finally, a new steganography framework based on the HSV model is designed to improve the security of the steganography scheme. Experimental and test results show that the proposed algorithm has good imperceptibility and can embed a large number of secret information.
