摘要： 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.

摘要： A secure and change-tolerant method for obtaining an identifier for a collection of assets associated with a computing environment. Each asset has an asset parameter and the computing environment has a fingerprint based on an original collection of assets and on a codeword generation algorithm on the original collection of assets. The method comprises: retrieving the asset parameters of the collection of assets and processing the retrieved asset parameters to obtain code symbols. An error-correction algorithm is applied to the code symbols to obtain the identifier. The method can be used in node-locking.

摘要： 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.
