Abstract: A method for implementing volatile cipher key and separate verification module by collecting physical features includes the steps of setting physical features sensor on a handset, collecting physical features information of every user in advance by a physical features sensor, transmitting the physical features to a control module, storing the physical features in a user database, resetting a cipher temporary storage unit after physical features sensor is away from the user's body, retrieving cipher data in the user database when registered user operates the handset, and checking by the control unit the user database has an identical record which matches the user's physical features.

Abstract: A method for implementing volatile cipher key and separate verification module by collecting physical features includes: physical features sensor is set on the handset, and control module can be set separately; physical features sensor can collect physical features information of every user in advance, and the physical features can be transmitted to control module, and stored in user database; after physical features sensor went away the user's body or cipher sent successfully, cipher temporary storage unit reset; when registered user is operating again by using handset, control unit can retrieve cipher data in said user database, and check whether same records exist or not; if same record exist, control unit give a instruction to lower-stage controlled object; if not, control unit delivers a warning information, and store an error record.

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.
