Electronic device and method for validation of a trusted user
First Claim
1. An electronic device, comprising:
- a user input data sensor system, including;
an input surface against which a user applies a finger to authenticate the user,a fingerprint sensor arranged relative to the input surface and configured to detect a user fingerprint and to generate corresponding user fingerprint data, anda tremor sensor arranged relative to the input surface and configured to detect involuntary tremor movement of the user finger and to generate corresponding user tremor data, andwherein a single application of the user finger to the input surface triggers the user input data sensor system to i) detect the user fingerprint and the involuntary tremor movement of the user finger from the single application of the user finger and ii) generate each of the corresponding user fingerprint data and the corresponding user tremor data;
a data memory to store user input data corresponding to a trusted user, the user input data including fingerprint data of the trusted user and tremor data of the trusted user;
a processor system configured to;
receive the user fingerprint data and the user tremor data generated by the user input data sensor system in response to the single application of the user finger to the input surface;
execute a fingerprint authentication algorithm to match the received user fingerprint data with the stored fingerprint data of the trusted user for producing a first output,corresponding to and separate from the execution of the finger print authentication algorithm, execute a tremor authentication algorithm to match the received user tremor data with the stored tremor data of the trusted user for producing a second output, andvalidate the trusted user by combining the first and second outputs resulting from the fingerprint authentication algorithm and the tremor authentication algorithm, respectively.

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.
