Recently, 3D media and its immersive experience became more attractive and widely used due to the development in network technology and decrease the prices of the display devices. The 3D videos that are created by DIBR techniques are getting a view of interest in the last years because of its visual reality and using it in many applications. Since DIBR takes the original colour with a depth view and generated two virtual views left and right, Copyright protection of DIBR is a difficult task because the centre, left-eye, and right-eye views need to be protected. In this paper, a dynamic, secure, and invariant watermark system is proposed to keep the copyright and ensure the authentication of 3D Video, where different watermark bits are embedded in different locations within the 3D video frame. The watermark bits are secured by encrypting it with the modified stream cipher algorithm. Experiment results show the secured watermark system embeds different watermarks with keeping the quality of the 3D Video system and makes the system more tolerant to attacks and the watermarks are extracted from the centre and generated rendered views correctly with minimum error rate after an attack.
