摘要
En 中文
In this paper, scene-based fingerprinting method for traitor tracing is proposed which is computationally less complex and handles large user group, say 1011 users while requiring few frames to embed the watermark. The proposed method uses QR code as a watermark due to its three main features: (1) inherent templates, (2) noise resiliency, and (3) compact size. The proposed method creates the QR code watermark on-the-fly which is then segmented and embedded parallely inside the scenes of video using the watermarking key. The features of QR code, segmentation, and watermarking key not only help the proposed method in supporting a large user group but also make it computationally fast. Further, synchronization issues may arise due to addition and deletion of scenes. To avoid such scenarios, the proposed method matches the inherent templates present in QR code with the templates present in the segments of the extracted watermark. Experimental results show that the proposed method is computationally efficient and is robust against attacks such as collusion, scene dropping, scene addition, and other common signal processing attacks.
