In the figure, the digital key management method is applicable to a lock, which includes the following steps. First, a digital key is disposed on a carrier (step S21), wherein the digital key is preferably a code and the carrier is preferably a mobile phone or a radio frequency (RFID) chip.

A usage rule corresponding to the digital key is stored in a storage unit (step S22). After the digital key is read by a reading device (step S23), a processing unit compares the digital key and the usage rule to generate a control signal (step S24). And controlling the lock according to the control signal (step S25).

Wherein, the usage rule records on which carrier the digital key system is configured, and records the code of the digital key, and encodes the digital key with The cooperation of the carrier determines the legality of the digital key and whether it has the authority to unlock the key.

For example, if a plastic user uses a mobile phone door number as a digital key, the mobile phone door number is paired with the lock when the usage rule is written. When using, first use the reader to read the door number of the mobile phone. At this time, the processing unit compares the mobile phone door number (ie, the digital key) with the usage rule in the database, and if it matches, transmits an unlock signal. To the lock to achieve the purpose of unlocking.

Please refer to FIG. 3, which is a functional block diagram of the verification and unlocking system module of the digital key control system of the present invention. In the figure, the verification and unlocking system module 30 includes at least a digital key receiving layer 31, a digital key verification layer 32, an unlocking command transmission layer 33, an unlocking control layer 34 and a physical lock layer 35.

The digital key receiving layer 31 can receive a plurality of input devices, which can be a digital PIN pad, a Bar-code Reader, a radio frequency (RFID) reader, a mobile phone dialing entry number reading, or A receiving device such as a biometric fingerprint reader or the like, which may represent the same meaning, or may respectively indicate different meanings of use, for example, using a digital PIN pad as a locking receiving device, and using a mobile phone to dial the entry number. The way is as a function of unlocking.

The digital key verification layer 32 can be linked to the database to manage a large number of usage rules, and in a comparative manner, for example, whether the encoding of the digital key matches, or whether the time limit of the digital key is within a valid use period. In order to confirm whether the digital key has the effect of unlocking it.

In the open unlock command transmission layer 33, the unlockable control signal is issued mainly after the digital key verification layer 32 completes the verification process. The control signal can be connected by means of simple line connection, wireless radio frequency reading, wired network connection or wireless network connection. In the wireless network connection mode, it is preferred to use WiFi, GPRS, WiMAX or Zigbee wireless transmission mode, and in the process of transmission, the content of the transmission can be encrypted to improve its security.
