Abstract: Blockchain-based proof of presentation of content on a media channel, including: generating, upon receiving a request to generate, at least first, second, and third parameters, wherein the first and second parameters are input parameters and the third parameter is calculated as an output parameter of a one-way cryptographic function; generating a first type of block by incorporating the first and third parameters into the first type of block; validating the first type of block and the blockchain; appending the first type of block to the blockchain when both the first type of block and the blockchain are declared valid; and embedding the second parameter into the content that is to be made available on the media channel to produce tainted content.

Abstract: Blockchain-based proof of presentation of content on a media channel, including: a blockchain; a generator configured to generate at least first, second, and third parameters, wherein the first and second parameters are input parameters and the third parameter is calculated as an output parameter of a one-way cryptographic function, the generator configured to incorporate the first and third parameters into a first type of block and append the first type of block to the blockchain; an embedder configured to receive and embed the second parameter into the content to produce tainted content; and a probe configured to monitor the media channel for the tainted content and to extract the second parameter from the tainted content.

Abstract: The present invention is directed to a process for making Chloro-Substituted Nucleoside Phosphoramidate Compounds of formula (I): which are useful for the treatment and prophylaxis of HCV infection. The present invention is also directed to compounds that are useful as synthetic intermediates for making the compounds of formula (I).

Abstract: A mobile terminal for use with a cellular or mobile telecommunications network includes a normal execution environment (operating system) (30) and a secure execution environment (32) comprising a Mobile Trusted Module (MTM). The mobile terminal enables the software of the terminal in the secure execution environment (32) to be updated. The terminal 1 may be provided with minimal software initially in the secure execution environment (32), and is operable to subsequently update the software by over the air transmission of software. Also disclosed is a method for managing rights in respect of broadcast, multicast and/or unicast (downloaded) data, relevant in particular to managing access to a broadcast video data stream complying with a mobile digital broadcast scheme. The method defines a service protection platform implemented on mobile terminals having both normal execution environment (i.e. the operating system) and secure execution environment.

Abstract: In a digital rights management (DRM) scheme a mobile terminal (1) registered with mobile telecommunications network (3) obtains encrypted content data (26) from content provider (21) and a rights object (28) containing a license to use that data from rights issuer (23). The mobile terminal (1) is associated with mobile terminal (11), PC (25) and PDA (27) in a domain. Various arrangements are disclosed for enabling a second device to consume the content data (26) received by the device (1). The content data (26) is consumed on the second device in a controlled manner. The second device may or may not be a member of the domain (24). The first device may enable the second device to temporarily join the domain (24), if the second device is not a member of the domain (24), in order to allow the second device to consume the content. In another embodiment the first and second devices may already be a member of the same domain (24).

Abstract: When a secure boot operation fails, the operation of a mobile telecommunications terminal can be severely impacted. In order to lower the impact on the user, one example embodiment of the invention relates to a method for automatically implementing a “safe boot” mode, whereby code can be accessed solely for the purpose of handling failed operations and if necessary providing limited services from the failing terminal.

Abstract: A framework whereby mobile terminals are configured and managed by a central server. In accordance with one aspect of the present invention, there is provided a mobile telecommunications terminal including a first execution environment and a second execution environment, each execution environment being arranged to execute a respective device management agent and each agent issuing, in accordance with instructions from a device management server, management actions that act upon one or more respective management entities running within one or more of the execution environments; wherein the management entities of the second execution environment are grouped into a management structure, the management structure being one of the management entities within the first execution environment, whereby the he first and second execution environments permit the device management server is permitted to manage applications and/or services running within both.

Abstract: A method of authenticating mobile user equipment in a mobile telecommunications network comprising the steps of receiving an authentication element from a serving network (SN) to which the user equipment is not directly subscribed, extracting the authentication management field (AMF) from the authentication element, generating in response at least to a predetermined value of the authentication management field (AMF), a key set identifier (KSI), and passing the key set identifier (KSI) to the serving network (SN).
