A method of stenographical information transfer in the syndrome of interference immune Hamming (2r – 1, 2r – r – 1) and Golay (23, 12, 7) codes is considered. The algorithm for inserting data uses additional information on the carrier sequence which leads to increased information efficiency of stenographical information transfer if compared to the algorithms based on substitution of the least significant digits of the carrier. It may be used in the problems of authenticating digital images of various applications by inserting digital watermarks.
