Authorised user control method for telecommunications device

摘要

The control method involves using a memory device associated with the telecommunications device (10). This is used for holding a reference identification, obtained via a detector (30) with a biometric sensor (32), for scanning a body part of the authorised user, such as the finger tip. The reference identification is compared with the digital identification information subsequently provided by the detector, for verifying the identity of the user, before the telecommunications device can be used. The detector unit with biometric senors may use infrared heat detection for constructing body part outlines
