A blockchain-based digital certificate deposit platform and certificate deposit method

Abstract

The invention provides a blockchain-based digital certificate storage platform. In this platform, the server performs hash operation on the file in response to the request of the client to submit the file in electronic format, and obtains the hash value corresponding to the file; The Greek value is used to store and obtain the storage ID of the file; the server interacts with the blockchain network, and submits the hash value, storage ID, and file creation information corresponding to the file to the blockchain network; The transaction data is successfully stored through the smart contract and packaged into a block, and then the successfully stored block transaction ID value is returned to the server; the server locally stores the submitted file and the hash value corresponding to the file, storage ID and transaction ID, and Returns the storage status information of the file to the client. The invention can guarantee the authenticity and reliability of data.

Description

technical field [0001] The invention relates to the technical field of electronic data storage, in particular to a blockchain-based digital certificate deposit platform and certificate deposit method. Background technique [0002] Blockchain technology is a cutting-edge technology that emerged in 2009. This technology integrates various computer technologies such as distributed storage, point-to-point network, encryption technology and consensus algorithm. Due to its characteristics of decentralization, independence, security and anonymity, blockchain has received extensive attention. Blockchain technology is not limited to financial aspects, but has begun to expand its integration with other fields, such as supply chain and identity management. Most of the more common distributed file systems at this stage are based on the GPL open source protocol, and store data in the server in the form of objects and files.

AI Technical Summary

Problems solved by technology

Most of the more common distributed file systems at this stage are based on the GPL open source protocol, and store data in the server in the form of objects and files. The communication protocol of the cluster nodes usually uses the TCP protocol, which is basically centralized storage. There is still a single point of failure in the way

In addition, encrypted database is also an important means of electronic certificate storage, including front-end service agent and encryption gateway technology, application layer encryption technology transformation, file-level encryption and decryption technology, etc., but these technologies have problems such as complex operation and opaque data

[0003] In the existing technology, ordinary deposit certificates only store electronic data in the centralized server in the form of backup. Since electronic data is very easy to be damaged, it is easy to cause defects, breakpoints, incomplete evidence, etc. during the transmission process. Fault

This not only has high technical requirements for the third-party evidence storage platform, but also requires reducing the number of transfers and handovers in the generation, storage, storage and subsequent use of electronic data. If these electronic data are stored on the central server, It will inevitably increase the risk of data tampering and integrity will be destroyed

Moreover, the third-party certificate storage platform is basically operated by the enterprise, and unexpected situations such as unstable services are very likely to occur.

In legal practice, a single or partial piece of electronic evidence is far from enough to support the judgment of the entire case, which is obviously beyond the reach of ordinary evidence deposits.

[0004] The ordinary way of depositing evidence cannot meet the needs of the industry in terms of modification records of electronic documents. It cannot solve the problems of recording modification time, modification person and version content before modification, and cannot trace the historical source of digital information.

Moreover, in the event of data loss or damage, the correctness and integrity of the restored data cannot be guaranteed when restoring the data

In addition, although existing evidence storage methods generally use encryption to ensure data security, there is still a risk of being deciphered
