1. A method of instant clearing electronic lock after key-cipher use based on a system comprising an electronic key main body, a lock main body, a lock operation unit, wherein the method comprises the steps of:

  • a. providing a human characteristic sensor, a key micro processing unit, a cipher generating unit, a cipher temporary storage unit, and a key cipher data transmitting unit on said electronic key main body;

    b. providing a lock cipher data transmission unit, a lock controlling unit, and a user database on said lock main body;

    c. collecting every user'"'"'s human characteristic information by said human characteristic sensor first, generating according cipher by said cipher generating unit, storing said cipher in said cipher temporary storage unit temporarily, transmitting said cipher data to said lock cipher data transmission unit by said key cipher data transmission unit, verifying said cipher'"'"'s registration, saving in said user database, clearing said temporary cipher storage unit after the human body is disconnected from said human characteristic sensor;

    d. collecting user'"'"'s human characteristic information by said human characteristic sensor when the registered user is using said electronic key main body to open the lock, generating said cipher again by said cipher generating unit, storing said cipher temporarily in said cipher temporary storage unit, transmitting said cipher data to said lock cipher data transmission unit through said key cipher data transmission unit, checking said cipher data on said user database by said lock controlling unit on said lock main body to confirm if there is a same record; and

    e. sending command to said lock operation element to open the lock if a same record is found in said database by said lock controlling unit, or delivering a warning message and saving an error message by said lock controlling unit if no same record is found.
