Shandong Port Rizhao Port Group Applies for Patent for Data-driven Port Cargo Traceability Method and System

Shandong Port Rizhao Port Group Co., Ltd. filed a patent application in October 2024 for a "Data-driven Port Cargo Traceability Method and System," with the publication number CN118941308A. The patent pertains to the field of cargo information traceability technology and aims to address the issue of existing port cargo traceability information being easily modified, leading to poor credibility.

The patent abstract reveals that the method primarily comprises the following steps:

1. Acquiring Traceable Information: Utilizing big data technology to collect traceable information about port cargo, such as cargo name, quantity, origin, transportation route, etc.

2. Information Encryption: Encrypting the collected traceable information to generate encrypted traceable information and traceable information keys.

3. Uploading to Blockchain: Uploading the encrypted traceable information to the blockchain network and obtaining a unique blockchain address.

4. Generating Keys: Generating public and private keys and encrypting the unique blockchain address and traceable information key using the public key to obtain the port cargo traceability ciphertext.

5. Decrypting to Retrieve Traceability Information: Decrypting the port cargo traceability ciphertext using the private key to obtain the port cargo traceability plaintext, thereby retrieving the traceability information of the port cargo.

This patent leverages big data technology, blockchain technology, and multi-layer encryption techniques to ensure complete recording and immutability of port cargo information, effectively enhancing the reliability and security of traceability information.

Specifically, storing encrypted information on the blockchain network ensures its immutability. Even if someone attempts to modify the information, a record will be left behind, facilitating traceability. Meanwhile, the encryption mechanism using public and private keys guarantees information security and privacy, as only those with the private key can decrypt the information.

The application of this patented technology will effectively enhance the transparency and credibility of port logistics, providing more reliable technical means for port cargo management and supervision. It will also provide more secure and reliable guarantees for cargo transactions, improving trade efficiency and safety levels.

The development of this patented technology reflects Shandong Port Rizhao Port Group's active exploration in technological innovation, contributing to the enhancement of port logistics levels and competitiveness.
