Zusammenfassung: | Copyright protection issues for personal user's User Generated Contents (UGC) have been arising with the rapid growth of Social Network Services (SNS), blogs, and video sharing services. In this situation, Creative Commons License (CCL) has been established as a convenient method to protect copyrights of UGCs. However, the lack of technical method to protect CCL causes illegal manipulations and sharing of CCL applied UGCs. In this paper, we propose a dual watermarking system which protects copyrights of CCL applied UGCs. Experimental results show that manipulations such as rescaling, cropping, clipping, temporal manipulation, and frame rate changing are detected by semi-fragile watermarks. Simultaneously, robust watermarks notify the CCL information after above manipulations. To prevent interference of two watermarks, robust watermarks are embedded at spatial domain while fragile watermarks are embedded at block based DCT domain. |
