By combining with characteristics of social network open widely and asymmetric digital watermarking technology leakage keys difficultly, a method of the digital content tort distribute and forensics is presented. It uses asymmetric digital watermarking algorithm loading the inseparable of copyright information to meet the requirements of difficult to be forged and quite good attack- resisting capability. Watermarks are extracted from the digital contents which have been attacked in the process of network transmission. Watermarks are transformed into frequency domain, then extracted tort information through the clustering algorithm. Finally, this method is simulated and analyzed. Results show that it has higher security and forensics integrity and can prevent illegal copy and proliferation, so that it protects intellectual copyright rights.
