【Abstract】 A new digital image hiding algorithm is presented which is based on adaptive amalgamation-coeffecient-matrix. The amalgamation-coeffecient-matrix is introduced compared with the traditional amalgamation scheme. With the statistical result of the textures of carrier image and secret image, the new algorithm performs better. The amalgamation-coeffecient-matrix can act as the key word. The experimental result shows that the approach is of high performance in amalgamation. Unlike the traditional scheme, it’s impossible for an attacker to get the total matrix, in this way the new algorithm is robust to some extent.更多还原
