Robust Scheme of Digital Video Watermarking

Priyanka Patil | Chandrakanth Biradar

Abstract: Watermarking technique mainly used for copyright protection and owner authentication. Every day huge data are embedded in the digital media or in distributed over the internet. The data such distributed can be easily replicated without any error, and putting the rights of their owners at risk. Even when the encrypted for distribution, data can easily be decrypted and copied. The one way to discourage illegal duplication is to insert information known as watermark, in the potentially vulnerable data in such a way that it is impossible to separate the watermark from the data. Robustness to various attacks is the main consideration for watermarking scheme. The original image increases its robustness of the watermarking dependency but the same time we have to make sure that the watermark is imperceptible. The proposed algorithms have robustness against various attacks like dropping of the frames, averaging and collusion. The work is started with comprehensive investigation of modern technologies of watermarking, and noticed that none of the standing arrangements is proficient of resisting all the attacks. The objective of digital video watermarking is to increase the PSNR (peak signal noise ratio) and MSE (mean signal error). The process of this comprehensive video watermarking scheme includes in detail of watermark embedding, watermark pre-processing and also video pre-processing. The proposed scheme here has a high degree of invisibility. In this scheme, the embedded watermark can successfully survive after different attacks.
