Instant clearing electronic lock system after key-following cipher use and realizing method therefor

Abstract

A kind of method for electronic lock system making the key-following password tidy up immediately after use, in which: a. establish human characteristic sensor and temporary password memory on the main body of the electronic key and data transmission unit of the lock password, lock controlling unit and user's database on the lock main body; b. firstly, human characteristic sensor gathers every user's human characteristic information that can be changed into corresponding authentification code in the producing unit for the password and deposited into the temporary password memory temporarily, meanwhile transported into data transmission unit of the lock password through data transmission unit of the key password; secondly, the password is deposited into the user's database after being registered and confirmed; c. when the human characteristic sensor leaves the human body or the authentification code is conveyed successfully, the temporary password memory is tidied up.
