Numerical technologies increase the ease of transmission, storage and modification of multimedia content, but also makes authentication and copyright management difficult. Robust watermarking is a solution that appeared about ten years ago. It embeds a message (author name, numerical signature, . . .) within a host multimedia document. This process must not be perceptible in order not to spoil the regular use of the watermarked documents. Moreover, one must be able to correctly extract the message despite modifications of the host (i.e. attacks). Although the first approaches were empirical, watermarking was quickly considered as a communication problem. This work deals with a novel watermarking scheme based on a wide spread spectrum (a com...
