Abstract
Digital watermarking is a powerful way to protect author’s copyrights and to prove that a digital content has not been modified. Watermarking is the process of altering the original data file, allowing for the subsequent recovery of embedded auxiliary data called watermark. A subscriber, with knowledge of the watermark and how it is recovered, can determine (to a certain extent) whether significant changes have occurred within the data file. Researchers have also developed techniques that can help to identify portions of an image or speech signal that may contain unauthorized changes. This can be useful, for instance, in front of a court. In this paper, we present some recent applications in image and speech processing. We think that some more applications will appear in the future, and specially, commercial devices able to insert a digital watermark in a multimedia content. This is the milestone to popularize these systems.
