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. |
