Stereoscopic Watermarking

The multiplication of stereoscopic content, and their high added values increase the risks of digital piracy. Therefore, we need to find the means of preserving intellectual property rights, without imposing additional operational constraints in the chain of production, distribution and consumption of this content. Digital watermarking offers a solution to this issue, and consists of inserting additional information in a way that is imperceptible to the user and resistant to attacks. This chapter on stereoscopic watermarking is divided into four sections: (i) the first section concerns issues in the application of digital watermarking for stereoscopic content; (ii) the second section presents an overview of the state of the art of stereoscopic video watermarking; (iii) the third section compares the main classes of watermarking methods, considering their properties of transparency, robustness and the computation costs; and (iv) the concluding section offers perspectives for future research.
