This paper presents the performance evaluation of a watermarking algorithm, an image and video processing technique used for Digital Right Management. Software developments are largely used in image copyright applications but there is a lack of real time applications for video. A previous work in image watermarking was already done and proposed a new algorithm with very interesting security properties. Nevertheless, the software implementation of this watermarking scheme showed some restrictions concerning real time applications. Hence, we propose to extend the previous paper with a lighter version of the algorithm and a complete hardware implementation allowing us to deal with high throughput image/video applications, such as digital cinema.
