ABSTRACT:
A method for controlling the watermarking of a set of multimedia data includes performing a first detection operation for detecting the presence of a first type of watermark in the multimedia data and generating a first partial authorization or prohibition parameter in response to this first detection operation. The method further performs a second detection operation for detecting the presence of a second type of watermark in the multimedia data and generates a second partial authorization or prohibition parameter in response to this second detection operation. A final authorization or prohibition parameter is then generated on the basis of the partial authorization or prohibition parameters generated to authorize or prohibit the transmission of the multimedia data. A device for carrying out the method is also proposed.
