The electronic device may include a display configured to display an image on a panel based on a changed luminance The electronic device may include a processor configured to: activate a light receiving area of at least a portion of the fingerprint sensor based on whether the display is activated, and change a luminance of the display based on an illuminance value measured from the light receiving area in an off state in which pixels arranged on a panel of the display do not display an image.

This invention is directed to an electronic device with an embedded authentication system for restricting access to device resources. The authentication system may include one or more sensors operative to detect biometric information of a user. The sensors may be positioned in the device such that the sensors may detect appropriate biometric information as the user operates the device, without requiring the user to perform a step for providing the biometric information (e.g., embedding a fingerprint sensor in an input mechanism instead of providing a fingerprint sensor in a separate part of the device housing). In some embodiments, the authentication system may be operative to detect a visual or temporal pattern of inputs to authenticate a user. In response to authenticating, a user may access restricted files, applications (e.g., applications purchased by the user), or settings (e.g., application settings such as contacts or saved game profile).

The invention relates to a device for biometric identification with the aid of fingerprints and/or hand characteristics, the device comprising a sensor unit (1) directed at the region of an optical gate (2) in a scanning direction (S), wherein the optical gate (2) is adapted to initialize the sensor unit (1) for scanning an in-focus scan image or scan images of the fingers and/or hand of a person, wherein the device further comprises at least one light source (5), which is likewise directed at the region of the optical gate (2), wherein the sensor unit (1), the optical gate (2) and optionally also the light source (5) are coupled to a control and computing module (6) with software for controlling the device and its parts and for scanning a scan image or the scan images of fingers and/or a hand, and for evaluating the fingerprints and/or hand characteristics, wherein the sensor unit (1) is fixedly set to focus into a focal volume (3) which is assigned to the optical gate (2), and the sensor unit (1), the optical gate (2), the control and computing module (6) and optionally also the light source (5) are configured to scan a single in-focus scan image of the fingers and/or the hand at the time of the passage thereof through the focal volume (3).
