A Kind of Binary Image Complete Level Authentication Method Based on Hamming Code and Digital Watermark

摘要

Each pixel of the binary image can be viewed as a binary number. Base on this characteristic, we design a supervisory relationship. A detection image is gotten from the supervisory relationship and binary image. Based on this, a kind of pixel level digital watermark complete authentication method is put forward. This method is able to conduct binary image pixel authentication. When authenticating, only from the detection image, people can accurately identify whether a pixel point is falsified or not, furthermore, it has falsification localization and repair capacity.
