Abstract: A method that is performed by a content delivery network and includes receiving a content segment request containing a token containing an entitlement tag for restricted use, and in response, checking the token, and, upon a successful check of the token, transmitting the requested content segment to a requestor. The method further includes, for each of a plurality of received content segment requests, extracting the entitlement tag from the token of the content segment request and storing a record including at least the extracted entitlement tag, analyzing the stored records to detect if a number of instances of a same entitlement tag within a predetermined time period exceeds a threshold, and in case of a positive detection, storing the entitlement tag in a list of non-trusted tags.

Abstract: The invention relates to a method for inserting watermark assistance data in a bitstream of coded data comprising the step of inserting, in the bitstream, identification data identifying coded data to be substituted and, for each coded data to be substituted, at least one substitution data. The method further comprises a step of inserting in the bitstream a format data defining a manner of substituting the coded data to be substituted by the substitution data.
