Abstract: A method is proposed for acquiring, from a server, configuration information by a reception device connected to the server through a first network, the configuration information allowing the update of the internal setting of the reception device. Such method comprises, during an initialization stage: providing a filtering information allowing to obtain a filtering item to a communication interface; and during an operation stage: providing a request for the configuration information to the communication interface for allowing a terminal equipment connected to the server through a second network to obtain the request and to send a corresponding request to the server; receiving the configuration information provided by the server as part of a data stream sent through the first network.

Abstract: A method for securely receiving a multimedia content by a client device operated by one or more operator(s) involving a dedicated provisioning server of a security provider managing symmetric secrets used by the client devices and operators license servers. The provisioning server provides to the client device one or more generations of operator specific unique device secrets, which are then exploited by the various operators' license servers to deliver licenses such that authorized client devices can consume protected multimedia contents.

Abstract: A system for sharing a distributed revocation list on a blockchain includes circuitry that identifies an access attempt by a wallet on a first blockchain network, and adds the wallet to a blacklist. The blacklist identifies the wallet as suspicious. The circuitry generates a soulbound token, and airdrops the soulbound token into the wallet. The soulbound token identifies that the wallet belongs to the distributed revocation list and identifies the wallet as a suspicious wallet to blockchain networks.

Abstract: A device (40) for generating a watermarked stream (39), comprising: at least one input interface (41) configured to receive encrypted control messages (20) and conditional access streams (30) including a main stream (33) and protected watermarking data streams (35) from which a watermarking information (38) can be embedded in said watermarked stream (39); a security module (43) configured to process said control messages (20) and to control access to said conditional access streams (30); a descrambler (45) configured to remove protection applied on at least some of said conditional access streams (30); a watermarking unit (47) configured to generate the watermarked stream (39) from said conditional access streams (30) by selectively processing said watermarking data streams (35) depending on access data (AC, AR) included in some of said control messages (20).

Abstract: A watermarking scheme for traceability of leaked or illegally re-distributed over-the-top streaming content includes a two-step scheme in which the content is pre-marked server side by providing part of the content, encrypted under a global key, and a first set of complementary parts of the content including a first mark and encrypted under a set of first keys, and a second set of complementary parts of the content including a second mark and encrypted under a set of second keys. A marked encrypted content is made available to a client device via a particular combination of the parts of the content encrypted under the global key, parts of the content having a first mark, encrypted under the set of first keys, and parts of the content having a second mark, encrypted under the second set of keys. The particular combination is based on an identifier of a client device.

Abstract: Method for distributing multimedia licenses by a server to a plurality of user devices in a distribution system of a multimedia service, the access of which is protected by a first protection. This method comprising verifying that computing resources used by the server do not exceed a maximal threshold, if so, generating and then transmitting regular licenses including said first protection in response to user device requests, otherwise switching the server to a singular mode of distribution aiming to protect the access to the multimedia service using a second protection, independent of the first protection; to generate and to transmit to the devices one singular license comprising the second protection; to verify that the computing resources do not exceed the maximal threshold, if so, to switch from the singular mode to a regular mode so as to protect the access to the multimedia content using only said first protection.
