Abstract: Provided is a method for authenticating a user in an electronic device. In illustrative embodiments, a fingerprint input from the user is be detected by receiving detection signals for respective sample points across an area of the fingerprint input. A determination value may be computed, which represents a degree of distribution of the detection signals according to signal strengths. It is then determined whether the determination value falls outside a preset reference range. If the determination value falls outside the preset reference range, the method determines that the fingerprint input from the user is invalid.

Abstract: A method and electronic device are provided. The electronic device includes a first touch sensor and a processor. The processor implements the method, which includes detecting, via a first touch sensor of the electronic device, sensor information from a touch object, determining, via a processor of the electronic device, a state of the touch object based on analysis of the detected sensor information, and adjusting a touch sensitivity for the electronic device according to the determined state of the object.
