Abstract: In one example in accordance with the present disclosure, a computing device is described. The computing device includes an encryption device to encrypt, using an encryption key, a document to be rendered. A generating device generates multiple shares of a decryption key using a secret-sharing scheme. A threshold number of the multiple shares allows decryption of the document. A transmit device transmits different shares of the multiple shares to different devices. The document is rendered when the threshold number of multiple shares are rejoined at a rendering device.

Abstract: A method for monitoring access to a user account comprises receiving a user account login status from a target service in response to a user login request, comparing the user account login status with an expected status value at a user apparatus, and on the basis of the comparison, performing at least one of: synchronising the status value at the user apparatus with the user account login status from the target service, and executing a user login update process at the user apparatus.

Abstract: A method for location-based authentication of a device comprises receiving multiple device location fingerprints generated using respective ones of multiple device sensors, comparing the device location fingerprints with corresponding respective environment fingerprints generated using respective ones of multiple static sensors and generating a token for the device to authorise it to use one or more selected services.

Abstract: Examples associated with user authentication are described. One example system includes a set of authentication modules. A data store stores data describing disruption ratings of members of the set of authentication modules. A user confidence module maintains a confidence rating that a current user of a device is an authenticated user of the device. The confidence module controls execution of the authentication modules based on the confidence rating and on the disruption ratings of the authentication modules. The user confidence module controls execution of relatively less disruptive authentication modules when the user confidence module is confident that the current user of the device is the authenticated user of the device. The user confidence module maintains the confidence rating based on feedback received from authentication modules.
