Blockchain Based Certificate Deposit System for Judicial Departments

Abstract

In the traditional judicial system, the public security, procuratorate, court and judicial bureau all involve private information, so the data current and sharing of each department will be greatly restricted. To solve these problems, a blockchain-based public security, procuratorial, and judicial evidence storage system is designed, which can, to a certain extent, solve the morass of data sharing among various departments of the judicial system, and can ensure the privacy of data. The proposed scheme uses the chain structure of the permissioned chain FISCO BCOS as the blockchain platform and combines the Merkle tree and hash function to access data. The structural storage of data can ensure that the uploaded data is traceable and without being tampered with. The public security, judicial and judicial evidence storage system designed with blockchain technology can realize database sharing among various departments of public security, procuratorate, court, and judicial bureau, eliminate the risk of leakage and tampering in the process of case evidence flow, and protect citizens' privacy and national information safety.
