Abstract

The invention discloses a mobile phone unlocking system and method based on palm image information, mainly solving the problems of easy forgetting and easy cracking in the traditional mobile phone unlocking mechanism. The mobile phone unlocking system comprises a user registering module, a user identity authentication module, a palm information characteristic library, an interaction layer and a screen control module. a user interacts with the user registering module through the interaction module, shoots a new user palm photo, and finds characteristic information of dactylus prints and palm prints to be stored in the palm characteristic information base for registering through extracting an interest region on the palm photo; the user identity authentication module is interacted with the screen control module during unlocking, a camera is automatically started for shooting the palm photo, the palm characteristic information is extracted and is compared with the characteristic information in the palm characteristic information base for matching, unlocking is carried out if the matching is successful, and the locking state is continuously kept if the matching fails. The system and method disclosed by the invention fully utilize the advantages of difficulty in forgetting and counterfeiting and convenience for carrying of biological characteristics, and has the advantages of high safety and good usability.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to identity authentication, in particular to a mobile phone unlocking system, which can be used for identity recognition when the mobile phone is unlocked. Background technique [0002] With the rapid popularization of smart phones, mobile phones are no longer just used as personal communication tools to follow users every day, but mobile devices that can enjoy various applications anytime, anywhere. In addition to having all the functions of ordinary mobile phones, smart phones also have the ability to wirelessly access the Internet, an open operating system, humanization and strong scalability. And precisely because mobile phones are becoming more and more powerful, the security of mobile phones cannot be ignored: various account information, emails, transaction passwords, photos, and personal privacy all leave their imprints on this mobile device. Theref...
