A binary image watermark authentication method based on Hamming Code

Hamming code is of a forward error correction coding ability,the data error correction is carried out at the receiver,without the request of re-sending,and the original data can be correctly obtained from the wrong data.

A Hamming code error-correcting system based on FPGA is designed for this purpose,the principle of its implementation is elaborated on from two sides,one is the sending side which completes Hamming coding,the other is the receiving side completes correcting and data gaining from the Hamming code,th.

(7,4) Hamming code was used to encode the watermark to improve its robustness, and also embed its verified pattern into the complex ha.
