Protection and Monitoring of Content Diffusion in a Telecommunications Network
First Claim
1. A method of supervising the distribution of content in a telecommunications network when data specific to a given acquisition of rights to the content has been written therein, wherein the method comprises processing of the content during its transfer over the telecommunications network by:
- analyzing the content and extracting the data specific to said acquisition therefrom with the aid of a detection probe situated in the telecommunications network;
accessing the acquired rights to the content in a storage medium with the aid of the extracted data specific to the acquisition; and
determining if the transfer of the content in progress is legitimate.

Abstract
The invention relates to supervising the distribution of contents in a telecommunications network (R). A content contains data specific to a given acquisition of rights to the content, written in the form of a digital watermark (WM). During its transfer across an access network (RA), the content is analyzed to detect the presence of a digital watermark. The data specific to the acquisition is then extracted from the watermark and sent with data characteristic of the transfer in progress to central supervisory equipment (300) of the telecommunications network (R) in order to determine if the transfer in progress is legitimate.
