摘要： A method for facilitating secure communication between a user device and a network device. Encrypted data from a user device is received at the network device. The encrypted data is encrypted based on first physiological data captured by a first sensor of the user device. The first physiological data is representative of a physiological characteristic of a user of the user device. A second sensor of the network device captures second physiological data representative of the physiological characteristic of the user. A common key for encrypting further data transferred between the user device and the network device is determined, based on the encrypted data and the second physiological data. Further aspects relate to other methods for facilitating secure communication between a user and network device, a network, and a method of operating a network.

摘要： A method of configuring a user device. The method comprises sending, from the user device to a node of a distributed ledger network (DLN), the node configured to store a distributed ledger of the DLN, a request for characteristic data indicative of a characteristic associated with a service provider, receiving, at the user device, a response from the node of the DLN in response to the request, and configuring a functionality of the user device accessible to the service provider, based at least in part on the response from the node of the DLN. Further aspects relate to a data processing system, a network, and a method of operating a network.

摘要： A computer implemented method of access control for a user device having at least one component for determining behaviours of the user, the method comprising: defining a training period during which access to the device is determined based on a credential-based authentication scheme wherein each access determination is used to generate an item of training data including at least a result of the credential-based authentication and a behaviour of the user; training a machine learning classifier based on the training data such that the classifier is operable to classify user behaviour as compliant or non-compliant such that compliant behaviour is determined by the classifier to be consistent with prior behaviour for permitting access to the device subsequent to the training period; and responsive to a determination that a behaviour subsequent to the training period is classified as non-compliant, requesting a credential-based authentication of the user and permitting access to the device in response to the credential-based authentication, wherein permitting access to the device further includes constructively training the classifier based on the subsequent behaviour as a compliant behaviour by providing the subsequent behaviour as an additional training example.

摘要： There is provided a computer implemented method for accessing a resource at a computing device, as well as for controlling access to a resource by a computing device. The method for accessing the resource, receives a policy indicating a set of conditions under which access to the resource is permitted, determines whether each of the conditions are initially present based on an output of one or more sensors of the device, and monitors the one or more sensors to detect a change in the presence of one or more of the conditions. In response to detecting the change in the presence of one or more of the conditions, the method determines whether each of the conditions are present. In response to determining that each of the conditions is present, access to the resource is enabled. In response to determining that at least one of the conditions is not present, access to the resource is prevented.
