Developed steganographic algorithm is compressive strength algorithms for arbitrary cover images including attacks with low quality factor. Cover is digital image stored in arbitrary format. Development of proposed algorithm based on existing analogues that based on general approach to the analysis of the status and technology functioning of information systems. The main advantage of the new steganographic algorithm is 6 times increase of its capacity, compared with the algorithms which it is based. The results of computational experiment confirming the high performance decoding of embedded information by compression attacks with low quality factor. [ABSTRACT FROM AUTHOR]

The paper focuses on new steganographic algorithm development. Proposed algorithm is stable to compression, including high rate compression, and based on singular vectors insensitive of image matrix blocks which corresponding to maximal singular values. Algorithm is polynomial of degree 2. The results of numerical experiments confirm the efficiency of the proposed algorithm. [ABSTRACT FROM AUTHOR]
