【 摘 要 】

[b]Abstract[/b]. The LSB algorithm is one of the most studied steganographic algorithms. There are several types of attacks that can detect the fact of conducting cover communication — chi-square attack and RS. This paper presents modification of the LSB algorithm which introduces fewer changes to carrier than the original LSB algorithm. Modified algorithms use a compression function, which significantly hinders the detection process. This paper also includes a description of main steganalytic methods along with their application to the proposed modification of the LSB algorithm.[b]Keywords[/b]: steganography, cyclic code, error correction codes, LSB, BCH, chi-square, steganalysis
