Abstract

Secure sharing of the digital video content over the Internet requires the use of modern techniques of protection. This paper describes the insertion of the encrypted watermark in the uncoded video content as a way of protecting copyrights. The impact of the prediction structure in the H.264 encoder to the survival of the inserted watermark is tested for two schemes. The watermark is encrypted with multistage Arnold transformation, and on the reception, an advanced algorithm for the realized by the SSIM index 0.71521 for an IBBBBBP scheme has been applied. The results obtained through the displayed example justify the application of multistage Arnold transformation for the video copy protection and raise security to a higher level.
