To solve the problem of automatically identifying the copyright labels in case of adopting watermarking in the copyright management of wireless multimedia messages (MM), this paper, by considering the possible attacks on the watermarks, proposes an identification method based on Gabor wavelet characteristics. Since the Gabor wavelet filtering has good performance in local, multi-directional and multi-scale analysis, to exploit the advantages, the proposed scheme uses the filtering to extract the set of characteristics of copyright labels and identifies it by computing and comparing the distances between the set and the stored ones. The analysis and experiments show that the method can meet the requirements of MM’s copyright management, and, with the accuracy of identification be more than 95% under the conditions presented, well support the copyright management of multimedia messages.
