Abstract: A new approach to information hiding based on the LSB (least significant bit) method is proposed. A static method for embedding information in a color image based on the matrix representation of individual blocks and estimating their determinant modulus is proposed. Numerical modeling evaluated the possibility of the proposed method to withstand various methods of steganalysis. Its advantage is shown both in the degree of security and in the amount of embedded information. This algorithm can be used for embedding in image by formats without compressing information.

Keywords: steganography, stego container, steganalysis, determinant, LSB, RS-steganalysis, chi-squared test steganalysis, visual analysis of bit slices.
