Abstract: Method for validating a trusted user of an electronic device, which electronic device comprises an input surface, e.g. on a key, dedicated for application of a user finger; a user input data sensor system, including a fingerprint sensor connected to the input surface for detecting user input fingerprint data, and a tremor sensor for detecting user input tremor data; data access to stored user input data corresponding to a trusted user; and a main processor system configured to match detected user input data with stored input data for validation of a trusted user. A triggering algorithm may run in a sub-sensor system, for sensing device handling and comparing sensed device handling with stored data. If the comparison reveals that user input is likely to occur based on the, a command is sent to the main processing system to trigger activation of tremor sensing and matching.
