Towards real-time video watermarking for system-on-chip

In the past few years, much research on watermarking has been focused on improving robustness to attacks. The starting point of the present study is an R&D algorithm which was not optimised for still images, but offered a good trade-off in terms of capacity, visibility and robustness, and worked in a full blind manner. We have focused on adapting it to video and on optimising it to the world of embedded terminals, such as digital still cameras, digital television and wireless terminals, where the computing power and storage resources of a Pentium are not available. Results of our adaptations are shown in the form of execution times versus platform capabilities. This work is the result of a close collaboration between the Eurecom research institute and STMicroelectronics.
