Protection and Monitoring of Content Diffusion in a Telecommunications Network |
摘要 |
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.
