ZhongBo Information Technology Research Institute Applies for Patent on Blockchain-Based Secure and Trustworthy Electronic Evidence Management Method

On January 8, 2025, the State Intellectual Property Office of China revealed that ZhongBo Information Technology Research Institute Co., Ltd. had applied for a patent titled "A Blockchain-Based Secure and Trustworthy Electronic Evidence Management Method," with publication number CN119249471A and an application date of August 2024. This patent technology leverages blockchain technology to enhance the security, reliability, and management efficiency of electronic evidence while ensuring effective user privacy protection.

The patented method comprises several key steps: Firstly, users register a decentralized identifier (DID) through a distributed trusted digital identity authentication module. This unique DID ensures effective identification and verification of user identity throughout the process, preventing forgery and impersonation. Next, users submit their generated DID and legal identity information to a third-party trusted authority (TA) for verification and binding. This step further verifies the authenticity of user identity and ensures the association between the DID and legal identity information. After successful verification, the system generates a Trusted DID (TDID) bound to the legal identity information and records this information on the blockchain.

During evidence upload, users undergo another identity verification process through the electronic evidence secure storage module. Only verified users can upload evidence. Upon successful verification, the evidence is uploaded to IPFS (InterPlanetary File System), a decentralized distributed file storage system. The IPFS-stored evidence file generates corresponding metadata, including the file hash value, upload time, and user DID. This metadata is then recorded on the blockchain, creating an immutable record of the evidence.

The evidence metadata on the blockchain is used for evidence access and verification, and can be updated based on access and verification results. For example, if evidence is accessed or verified, the system records the access time and verification results, forming a complete evidence chain to ensure integrity and traceability. The immutability of blockchain technology ensures the authenticity and reliability of the evidence, preventing malicious tampering or deletion. This method utilizes the decentralized nature of blockchain to significantly improve the security of electronic evidence.

The innovation of this patent lies in its comprehensive consideration of the security and reliability of the entire electronic evidence management process. From user authentication to evidence storage and access, each stage employs appropriate security measures to minimize security risks. By storing electronic evidence metadata on the blockchain, the method not only improves the efficiency of evidence management and retrieval but also provides reliable long-term preservation. The distributed storage further reduces the risk of single points of failure, ensuring access and verification even if some nodes fail.

Furthermore, the patent prioritizes user privacy protection. By using DIDs and encrypting sensitive information, the method effectively prevents sensitive information leakage, enhancing the security and privacy of electronic evidence. A rational access control mechanism ensures that only authorized users can access relevant evidence information, further safeguarding user data security and confidentiality. The presence of the third-party TA provides additional assurance for the overall system security and trustworthiness.

ZhongBo Information Technology Research Institute Co., Ltd., the applicant for this patent, was established in 2001 and is located in Nanjing. It's a research and experimental development-focused enterprise with registered capital and paid-in capital of RMB 100.08 million.
