Abstract
In this paper, we utilized the relationship between two blocks to generate the robust feature. Such a feature is very stable under various image processing operations. The XOR operation is applied to the feature and the watermark to create the secret key. Moreover, a mechanism is developed to resist the cropping attacks. The experimental results demonstrate our technique is highly robust against image processing operations.
