摘要

Abstract

This paper presents a zero-watermarking scheme based on the overall features of the image and timestamp. Firstly, an image feature matrix is generated according to the original image. Then the watermark image is expanded to the size of the image feature matrix. After that, the XOR operation is carried out for the image feature matrix and the expanded, and encrypted watermark image. This operation result is saved as a key to detect the watermark. At the same time, the scheme employs the techniques of the watermark embedding with image expansion, and the normalized image detection, so that the image has a strong resilience for rotation and shearing attacks. Experiments result show that the proposed scheme is robust to the attacks of normal image processing ways and geometric transforms, and thus this schme is feasible and practical.
