摘要：Due to extensive usage of internet, the exchange of data between users are also increasing rapidly.Security and copyright protection are becoming important issues in digital media applications and services. Owners ofthe digital products are troubled about illegal copying of their products. Digital watermarking throughout the lastdecade is improved due to the increase in the need for copyright protection. More specifically Creative CommonsLicense (CCL) has been established as a expedient method to protect copyrights of user generated digital products.However, the lack of technical method to protect CCL causes illegal manipulations and sharing of CCL. This paperpresents, embedding dual watermarking system which embeds both robust watermarks and semi-fragile watermarks forCCL protection and manipulation detection. A robust watermark is generated, in order to withstand frame drop andrescaling, which increases the overall robustness. Then the fragile watermark is embedded at DWT domain, robustwatermarks are embedded at spatial domain.
