Abstract :
Abstract-A novel steganography algorithm CRCsteg based on CRC method is proposed. CRCsteg exploits the 1-1 and onto mapping from x^j-1 to {R(x)}{0} over GF(2^k), s.t.1 ¿ j ¿ 2^k-1 and k = deg(R) +1, to embed the positive integer j into 2^k-1 bits cover stream. The new method has similar performance with previous matrices embedding schemes, and much simpler embedding/extracting codes and computation, as no need of matrix multiplication. With small and stable MSE, CRCsteg has no detectable influence on visual quality and statistical features. The value of parameter k varies controlled by a key. The action of parameter k on the speed and robustness is also discussed.
