103, calling an authorization terminal identity query contract to query an authorization terminal corresponding to the electronic lock identifier in the unlocking request message, and sending an authorization confirmation message to the authorization terminal, wherein the authorization terminal identity query contract is an intelligent contract deployed in a block chain network;
the authorization end is a user terminal which has ownership right for the designated electronic lock and can control the owner of the corresponding electronic lock to open according to the opening request of the request end to the electronic lock. The user terminal refers to a smart device for installing a corresponding client program, and includes but is not limited to a mobile phone, a tablet computer, a personal computer, and the like. In the embodiment of the invention, the client program comprises a first client program applied to the request terminal so as to realize the electronic lock control method applied to the request terminal provided by the embodiment of the invention; and a second client program applied to the authorization end, so as to implement the electronic lock control method applied to the authorization end provided by the embodiment of the invention. And the authorization terminal identity query contract is deployed in the block chain network and is used for querying the state data of the corresponding relationship between the pre-stored electronic lock identifier and the authorization terminal identifier so as to determine the corresponding authorization terminal identifier according to the electronic lock identifier contained in the unlocking request message, namely to determine the owner. Taking an express receiving and sending scene as an example, the authorization terminal identity inquiry contract refers to a unique code of an electronic lock used for searching the serial number of a vehicle owner according to the electronic lock of the vehicle trunk. The electronic lock identification refers to information capable of uniquely characterizing the identity of the electronic lock, and includes, but is not limited to, a name, a number, an id (identification), and the like for characterizing the identity of the electronic lock. The authorization terminal identifier refers to information capable of uniquely characterizing the identity of an owner, and includes, but is not limited to, a user identity identification card number (SIM card number) of a user terminal corresponding to the authorization terminal, a user account number, a user name, and the like.

and the authorization confirmation message is used for sending a verification request message for verifying the identity of the request terminal after the authorization terminal confirms. The block chain network receives an unlocking request message of a request end, calls an identity inquiry contract of the authorization end to determine the authorization end, and sends an authorization confirmation message to the authorization end based on the unlocking request message, so that the authorization end can judge whether an event corresponding to the unlocking request message sent by the request end is true based on the authorization confirmation message, if the event is true, the authorization end sends a verification request message to the block chain network after confirmation, and if the verification request message can be a confirmation instruction sent by aiming at the authorization confirmation message, the block chain network further verifies the identity of the request end according to the verification request message; if not, no confirmation is performed or a confirmation no instruction is sent to the blockchain network, and the process is ended.
Step 107, invoking a request end identity authentication contract to authenticate the identity of the request end according to a request end identifier in the authentication request message, wherein the request end identity authentication contract is an intelligent contract deployed in a block chain network;
the system comprises a request end identity authentication contract, a block chain network and a block chain network, wherein the request end identity authentication contract is deployed in the block chain network and is used for inquiring the state data of a pre-stored request end identification list so as to determine that the identity of a request end is a legal identity, namely that a requester is a legal user having an unlocking request message.
