Abstract

The invention provides a portable electronic device having a fingerprint identification function. The portable electronic device comprises a fingerprint sensing unit, a signal conversion unit, a processing unit and a storage unit which are electrically connected in sequence, wherein the fingerprint sensing unit comprises a touch control sensing module which can acquire fingerprint characteristic information by pressure. The touch control sensing module acquires the fingerprint characteristic information by pressure, the information conversion unit is used for extracting the fingerprint characteristic information and converting the fingerprint characteristic information into the fingerprint data, the fingerprint data is converted into the fingerprint image characteristic data by the processor unit, and the processor unit compares the fingerprint image characteristic data with the fingerprint characteristic data pre-stored in the storage unit and determines whether the electronic device is started to enter a normal working state according to the comparison result.

Description

technical field [0001] The invention relates to a portable electronic device, in particular to a portable electronic device with a fingerprint identification function. Background technique [0002] With the development of multimedia technology, portable electronic devices such as mobile phones and personal digital assistants (Personal Digital Assistant, PDA) have become necessary tools in people's lives, and important personal information of users is often stored therein. Therefore, it is necessary to set up certain identity authentication and rights management measures in the use of such products to protect the information stored in them, so as to prevent users' personal information from being accidentally leaked or stolen. [0003] Among the existing identity authentication methods, fingerprint identification (Fingerprint Identification) is a more advanced and widely used method. Fingerprint identification refers to scanning the user's fingerprint through the fingerprint ...
