Data processing method and device, and system

An electronic lock, comprising:

• receiver circuitry configured to receive encrypted data from an electronic key, the encrypted data including at least one piece of feature data that is obtained by the electronic key when an unlock operation is triggered, and the at least one piece of feature data including data representing a user that triggers the unlock operation;
• and
• processing circuitry configured to
• decrypt the received encrypted data to obtain the at least one piece of feature data,
• determine whether the at least one piece of feature data matches predetermined feature data, and
• execute the unlock operation when the at least one piece of feature data is determined to match the predetermined feature data.

An electronic unlocking system, comprising:

• an electronic key including
• first processing circuitry configured to
• obtain at least one piece of feature data when an unlock operation is triggered, the at least one piece of feature data including data of a user that triggers the unlock operation, and
• encrypt the obtained at least one piece of feature data to obtain encrypted data;
• and
• transmission circuitry configured to send the encrypted data to the electronic lock, and
• an electronic lock including
• receiver circuitry configured to receive the encrypted data from the electronic key;
• second processing circuitry configured to
• decrypt the received encrypted data to obtain the at least one piece of feature data;
• determine whether the at least one piece of feature data matches predetermined feature data;
• and
• execute the unlock operation when the at least one piece of feature data is determined to match the predetermined feature data.
