Abstract: There is described a challenge-response method for a computing device. The method comprises steps of: (a) receiving challenge data at a secured module of the computing device, the challenge data comprising image content encrypted using an encryption key, and the image content including a nonce; (b) the secured module recovering the image content through decryption using one or more keys associated with the encryption key; (c) the secured module of the computing device outputting the recovered image content; (d) capturing the image content as output by the secured module; (e) processing the captured image content so as to obtain the nonce; and (f) providing the nonce as a response. There is also described a computing device arranged to carry out the challenge-response method, a computer program for causing a processor to carry out the challenge-response method, and a computer readable medium storing such a computer program.

Abstract: There is described a method of obfuscating access to a data store by a software application. The method comprises accessing the data store using access operations.

Abstract: There are described methods and apparatus for generating an identifier of a computer device, which may also be an identifier of a software application installed on the computer device such as a web browser. Parameters of the computer device are collected, extended with dummy values, and reordered, to form a permuted extended set of parameters, which in turn is used to generate the identifier.

Abstract: A method of maintaining a list of recommended content items, the method comprising: receiving content list data, the content list data identifying a plurality of content items and comprising relationship data that identifies, for each of one of more of the plurality of content items, an associated set of one or more other content items in the plurality of content items; storing a current list of recommended content items; receiving an identification of a content item in the plurality of content items that has been selected by a user; and forming an updated list of recommended content items based on (a) the current list of recommended content items, (b) the selected content item and (c) the content list data.

Abstract: An electronic device is provided which comprises a plurality of processing units (IP1-IP6), a network-based interconnect (N) coupled to the processing units (IP1-IP6) and at least one monitoring unit (P1, P2) for monitoring a data flow of at least one first communication path between the processing units (IP1-IP6) and for forwarding monitoring results at least temporarily via at least two separate communication paths (MC1, MC2).

Abstract: The invention involves the migration of at least some of the content discovery and/or resource management tasks from a home network to a remote server by using a proxy device, such as e.g. a DLNA-compatible proxy server or a proxy server compatible with other and/or multiple standards, connected to the devices within the home network and also connected to the resource server via an external, network. The proxy device can obtain content-relation information and, possibly, also: device-related information from the devices within the home network and provide that information to the remote server which can use the information to create an integrated navigation interface for navigating and/or managing content available to all of the devices within the home network.
