Video indexing application based on watermarking using turbocode and side information

摘要

The aim of this paper is to present a technique to hide data in digital video based on a watermarking approach. The algorithm exploits the side information in the embedding phase; it uses error-correcting codes to improve the achievable robustness and different spatial and temporal masking function to hide the watermark. The watermarking approach is based on an algorithm working in the uncompressed video domain in order to reduce the computational cost. The proposed scheme has been implemented and tested under different attacks, in particular compression and transcoding attacks. The results show that side information and error correcting codes strongly improve the robustness.
