Method and device for storing unstructured data

Abstract

The invention discloses an unstructured data storage method and device, and the method comprises the steps: responding to a request instruction for storing unstructured data sent by a terminal, compressing the unstructured data through a public key of a block node, obtaining an unstructured data compression package, carrying out the Hash operation of the unstructured data compression package, and storing the unstructured data. And obtaining a hash value, generating an identifier of the unstructured data based on the generation time of the unstructured data compression package, the attribute information of the unstructured data and the storage address of the public key, and forming a voucher of the unstructured data with the hash value, and storing the certificate and the unstructured data compression package in a block chain. Therefore, due to the fact that the unstructured data can be stored in the block chain, frequent interaction between the block chain service node and the application server and between the block chain service node and the storage server is avoided, and the processing efficiency of unstructured data evidence storage is optimized.

Description

technical field [0001] The present application relates to the field of blockchain technology, and more specifically, to a method and device for storing certificates for unstructured data. Background technique [0002] With the continuous development of information technology, the issue of information security has received attention, and all kinds of data need to be protected. At present, blockchain technology has a high security factor for data access. The time sequence generated by each is connected into a chain. If you modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes, so it has the characteristics of data that is difficult to tamper with and decentralize. For unstructured data with irregular or incomplete data structure, theoretically, if the blockchain directly stores it, it will lead to serious low reading and writing efficiency and query efficiency. Based on this, the current pra...

AI Technical Summary

Problems solved by technology

For unstructured data with irregular or incomplete data structure, in theory, if the blockchain stores it directly, the efficiency of reading and writing and querying will be severely reduced. Based on this, the current practice is to perform hash operations on unstructured data , and then save the hash value in the block as text, and store unstructured data outside the block

[0003] However, under the current blockchain technology, the current practice does not store unstructured data in the blockchain, and does not give full play to the distributed storage function of the blockchain. Since unstructured data is stored outside the blockchain , making blockchain service nodes frequently interact with application servers and storage servers, seriously reducing the processing efficiency of unstructured data storage
