Abstract: To protect the digital content from being copied, shared or deliberately stolen, Digital Rights Management has become important for digital content protection. Digital watermarking is a widely used method for copy protection, user authentication, author identification and many more tasks. A novel method of digital watermarking using 2-dimensional error correcting codes (2D-ECC) for copyright protection of MPEG videos is proposed in this paper. An invisible watermark is embedded in the motion vectors with a key. At the decoder, using the key, the watermark is extracted by the 2D-ECC and then the original motion vectors are retrieved. A wrong key or tampering of the motion vectors retrieves a highly distorted video. The PSNR values above 50 dB and SSIM values above 0.9 obtained for the watermarked video frames show that they are totally indistinguishable from the original ones. Also a high embedding capacity of 2 bits/pixel is obtained by preprocessing the watermark before embedding.
