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. |
