Description

Technical Field

[0001] The present invention belongs to the field of information technology, and in particular relates to a system and method for remote verification of crew identity based on blockchain. Background Art

[0002] In recent years, the number of ships passing through the dam area has shown a rapid growth trend, especially the increase in small and medium-sized ships, which has further increased the pressure on navigation in the dam area. In order to save costs, some ships choose to operate without crew or choose temporary crew during the passage of the dam.

[0003] In order to effectively ensure that ships meet the minimum manning requirements, maintain the safety of the hub, and fully guarantee the safe passage of ships through the locks, for shipping management departments, the existing boarding inspection method can no longer meet the needs of large-scale passive verification of crew identities, and installing unified identity verification hardware equipment on ships will increase ship freight costs. Summary of the invention

[0004] The technical problem of the present invention is that the shipping management department urgently needs means of ship crew identification and detection to carry out remote crew identity verification and full-process supervision of ship crew.

[0005] The purpose of the present invention is to solve the above problems and propose a remote crew identity verification system based on blockchain, including: a ship-borne Beidou subsystem, the ship-borne Beidou subsystem includes a declaration information module, a task receiving module, a remote communication module, a face image recognition module and a review request module; Declaration information module, used to send ship declaration information to dam area management personnel; Task receiving module, used to receive ship inspection tasks sent by dam area management personnel; Remote communication module, used for remote communication between ship crew and dam area management personnel, and for receiving crew identity information and facial image information sent by management personnel; The face image recognition module is used to collect the crew's face image information and convert the image information into a hash value using a hash function, and verify it with the crew's identity information and face image information sent; The review request module is used to send a review request to the management personnel to check whether the received crew identity information and facial image information are complete.

[0006] Furthermore, the blockchain-based crew identity remote verification system also includes a ship declaration subsystem, a ship security inspection subsystem, and a ship dispatch subsystem; The ship declaration subsystem is used to receive the declaration information of the ships passing through the dam; The ship dispatching subsystem is used to prepare security inspection plans for ships according to the time sequence of ships entering the dam area and the types of ships; In the ship security inspection subsystem, the user arranges the security inspection content for the ship according to the ship security inspection plan.

[0007] Preferably, the shipborne Beidou subsystem communicates with the ship declaration subsystem, the ship security inspection subsystem and the ship Beidou subsystem through the Beidou 4G network.

[0008] The remote crew identity verification method using the blockchain-based remote crew identity verification system comprises the following steps: S1: The ship declares passing the dam through the ship Beidou terminal subsystem and sends the declaration information to the cloud server; S2: The ship declaration subsystem obtains declaration information from the cloud server and sends the declaration information to the ship dispatch subsystem for compiling ship security inspection tasks, which are then sent to the cloud server; S3: The security inspection subsystem obtains the ship security inspection task from the cloud server, and sends the crew identity information and facial image information from the cloud server blockchain to the ship Beidou terminal subsystem according to the security inspection task; S4: The Beidou terminal subsystem verifies the crew identity information with the crew information in the declared information; S5: The Beidou terminal subsystem enters the crew's identity and converts the entered crew photo into a hash value for facial image verification; S6: The Beidou terminal subsystem uploads the hash value of the successfully verified facial image to the blockchain in the cloud server for storage, and generates a pass through the security inspection subsystem and sends it to the Beidou terminal subsystem.

[0009] Preferably, step S4 includes the following sub-steps: S41. If the verification is successful, execute step S5; S42. If the verification fails, the Beidou terminal subsystem will issue an alert to the security inspection subsystem.

[0010] Furthermore, step S5 includes the following sub-steps: S51, if the facial image verification is consistent, execute step S6; S52. If the facial image verification is inconsistent, the Beidou terminal subsystem will alert the security inspection subsystem and mark the ship as a suspected problem ship.

[0011] Preferably, the initial verification and facial image verification also include a crew review request. The crew queries the crew identity and identification information through the Beidou terminal to see whether it is in the Beidou terminal subsystem. If not, a request to download the crew information is sent to the ship security inspection subsystem.

[0012] Furthermore, when the crew undergoes facial image verification for the first time, the Beidou terminal subsystem will verify the collected facial image information with the crew's certificate information. Preferably, step S6 also includes uploading the crew member's name, ID number, position, tenure, electronic signature and verification number to the blockchain.

[0013] Compared with the prior art, the beneficial effects of the present invention include: 1) The blockchain-based crew identity remote verification system of the present invention, the ship declaration subsystem and the ship security inspection subsystem communicate with the Beidou terminal subsystem through Beidou 4G, compile verification plans and send ship crew identity verification work, and store the verified crew information in the Beidou cloud server to realize remote verification of crew identity.

[0014] 2) The present invention introduces hashing to convert crew facial image information into hash values. When verifying the crew identity, the hash value is compared with the hash value stored in the blockchain, thereby improving the accuracy of crew identity verification and enhancing the management of ships passing through the lock by the management department.

[0015] 3) The Beidou terminal subsystem does not require the replacement of old equipment and can be installed in existing ship equipment, thus reducing ship freight costs. BRIEF DESCRIPTION OF THE DRAWINGS

If not, a request to download the crew information will be sent to the ship security inspection subsystem. After downloading the crew information, the crew identity verification will continue.

[0027] For ships that have been warned by the system and whose review requests have not been approved, the ship declaration subsystem will issue a manual verification task when the ship passes through the lock.

[0028] When a crew member performs facial image recognition for the first time, the Beidou terminal subsystem will verify the collected facial image information with the crew member's ID information. Step S6 also includes uploading the crew member's name, ID number, position, tenure, electronic signature and verification number to the blockchain.
