Meanwhile, the Hamming codes are used to embed secret bits, as well as a block code that can detect up to two simultaneous bit errors and correct single bit errors. In this paper, we propose an effective data hiding method for two quantization levels of each block of AMBTC using … Webber of tolerable bit errors in a code. When each two code words diﬀer in at least d min bits, one can deter-mine the number of faults that are safely detected and corrected. A decoder that exclusively detects errors, is able to detect d min − 1 erroneous bits. When the decoder corrects errors, (d min −1)/2 bit errors can be corrected.
