Abstract: A method for providing an authorization to access an interactive good by means of an access right issued by a first bearer device to or for a second bearer device by using a wireless communication means, the method including: by the first device, wirelessly obtaining a first information including at least a second device identifier, generating the access right including at least the second device identifier and an identifier of the interactive good, providing, to the interactive good, a second information including at least the access right, by the second device, wirelessly presenting an access request to the interactive good, by the interactive good, performing an identity check in order to at least verify the second device identifier, and, in case of successful identity check, providing the requested access to the interactive good.

Abstract: Disclosed herein are methods and systems for enabling legal-intercept mode for a targeted secure element.

Abstract: The present invention relates to a system and a method for reliably including a fingerprint or a watermark in a digital media content. In order to endure that the marking process will not be bypassed, the disclosed method includes insertion of the mark when the content is in compressed format. The disclosure covers ways and means for simplifying the process of including visible or invisible marks in the content using on-screen overlay techniques.

Abstract: A method of transmitting authorization messages to a plurality of mobile receivers comprises the steps of defining at least one set of authorization messages, a first part of which, forming a first message category, is intended for a first group of mobile receivers, a second part of which, forming a second message category, is intended for a second group of mobile receivers; creating a first authorization message packet containing at least the first part of the set of authorization messages; creating a second authorization message packet containing at least the second part of the set of authorization messages; transmitting the first authorization message packet over a first service, without previously sending information indicating to which mobile receivers the message packets are directed; and transmitting the second authorization message packet over a second service without previously sending information indicating to which mobile receivers the message packets are directed.

Abstract: Example embodiments are directed to a revocation lists management method, namely a verification method of a target device connected to a master device, the master device having means to receive a content transmitted by a broadcast centre via a data stream, the master device and the target device authenticating themselves by the exchange of a certificate having at least one certificate identifier. The method includes transmitting by broadcast a target device verification table containing a certificate identifier list, storing certificate identifier list in the master device, extracting a verification data associated to the content, the verification data including the activation or the deactivation of the verification of the target device. If the verification data includes the activation of the verification, the method includes verifying the certificate of the target device by the master device using at least one list stored to authorize or prohibit the exchanges of data with the target device.

Abstract: The aim of this invention is to propose different distribution and management methods of the revocation lists associated to anti-copying protection standards, in order to facilitate processing in a television broadcast environment by guaranteeing security against the piracy of the receiver equipment and of the equipment connected to this television broadcast receiver at the core of a home network. This aim is achieved by a verification method of a target device connected to a master device, the latter having means to receive a content transmitted by a diffusion centre via a data stream, the master device and the target device authenticating themselves by the exchange of a certificate comprising at least one certificate identifier, this method comprising the following steps: a. transmission by broadcast of at least one target device verification table containing a certificate identifier list, b. storage of this list in the master device, c.
