Abstract
En 中文
A novel multiple watermarks cooperative authentication algorithm was presented for image contents authentication. This algorithm is able to extract multiple features from the image wavelet domain, which is based on that the t watermarks are generated. Moreover, a new watermark embedding method, using the space geometric model, was proposed, in order to effectively tackle with the mutual influences problem among t watermarks. Specifically, the incidental tampering location, the classification of intentional content tampering and the incidental modification can be achieved via mutual cooperation of the t watermarks. Both the theoretical analysis and simulations results validate the feasibility and efficacy of the proposed algorithm.
