Embodiment 1

[0027] Such as figure 1 shown.

[0028] A kind of unlocking method based on handheld terminal equipment PDA and fingerprint identification technology, it comprises the following steps:

[0029] First, enter the fingerprint information of each unlocker into the control center computer in advance, and generate the fingerprint feature template information corresponding to the lock unlocker; the fingerprint feature template information in the control center computer can be communicated through wired or wireless communication. This example uses 2.4G Short-distance wireless communication, the communication distance generally does not exceed 100 meters, and can be transmitted to the handheld terminal device PDA with fingerprint entry function by using existing ZigBee, Bluetooth or special communication protocols; if personnel are transferred or resigned, they can Delete the fingerprints and feature template information of relevant personnel in time, and the operation is very conveni...

Embodiment 2

[0036] Such as figure 2 shown.

[0037] An unlocking system based on a handheld terminal device PDA and fingerprint identification technology, which includes: a control center computer 1 , a handheld terminal device PDA2 and a lock controller 3 .

[0038]The control center computer 1 has a communication module A for communicating with the communication module B that the handheld terminal device PDA2 has; The actually entered fingerprint information of the unlocker and a randomly generated group of random numbers RND1 corresponding to the unlocker are sent through the communication module A;

[0039] The handheld terminal device PDA2 has a fingerprint verification function, and the unlocking personnel need to perform fingerprint verification before unlocking the lock; the handheld terminal device PDA2 has a communication module B and a communication module C, and the communication module B is used to communicate with the control center computer 1. The communication module A ...

Abstract

The invention provides an unlocking method and an unlocking system based on PDA (personal digital assistant) and fingerprint. The method is characterized by comprising the following steps of: prerecording fingerprint, generating random data by a center computer, transmitting to a handheld terminal PDA, transmitting the random data into a lock controller to be verified after the fingerprint verification is carried out by the handheld terminal PDA, returning the data back to the handheld terminal PDA to operate in an encryption way after the verification is successful, transmitting the generated encrypted data into the lock controller to be deciphered, starting a lock after the deciphering is successful, and otherwise alarming and promoting to go through an unlocking procedure again. The system consists of the center computer, the handheld terminal PDA and the lock controller with a short-distance communication interface. According to the invention, the password does not need to be remembered, and the phenomenon that the password is lost or stolen can be avoided, so that the safety protection level can be greatly improved.

Description

technical field [0001] The present invention relates to a kind of security technology, especially a method for opening locks of high-level security units such as treasury and gun storehouse, in particular, a method of unlocking based on PDA and fingerprint identification technology. Background technique [0002] At present, vaults and gun stores, automatic teller machines, safes, safes, confidential file cabinets, etc. are all equipment with very high security requirements, and are key security parts. The key point of this type of security is the door lock. The door lock is generally a combination lock. The traditional one is mainly a mechanical combination lock, and the modern one is mainly an electronic password, and some use a dynamic password. But no matter what kind of password is used, as long as you master the password, you can enter the warehouse or open the cabinet door. Especially for fixed password locks, as long as the password is remembered, the code holder...
