Problems solved by technology

Although the blockchain ledger itself is shared between nodes, and the ledger records all service-related information on the entire blockchain, although the information on the blockchain ledger will undergo necessary processing such as encryption, there are still relatively large risks Being cracked, resulting in the leakage of customer privacy data
The existing solution still has the following two defects: on the one hand, there is a large amount of interaction between customers and securities companies, and all of them are transmitted to the public chain or alliance chain. The data volume is large and the synchronization is not timely; Acquisition, such as the number of daily active customers, the number of daily clicks, resulting in the disclosure of trade secrets

Abstract

The invention discloses a data protection method based on a block chain. The method comprises the following steps: S1, collecting multi-source heterogeneous data; s2, processing the collected multi-source heterogeneous data into a data stream with a specified format, and extracting a starting time, an ending time and a service type from the data stream to generate a data fingerprint; s3, assembling the obtained start time, end time, service type and data fingerprint into a message; and S4, storing the generated message on the block chain, wherein the original data is still stored in the local database and / or the local file. According to the invention, the multi-source heterogeneous data is converted into the message only containing the start time, the end time, the service type and the data fingerprint, and the message is stored on the block chain, so that the technical problem that in the prior art, the overhead of computing resources, storage resources and bandwidth resources of the block chain is too large due to the fact that all data needs to be recorded and chained one by one is solved; and the problems that the interactive data between the client and the security company is easy to delete and tamper, and the security and completeness of the data cannot be ensured can be solved.

Description

technical field [0001] The present application belongs to the technical field of information data security, and specifically relates to a data protection method and protection device based on blockchain. Background technique [0002] As the business scope of securities companies becomes wider and wider, there are more and more interactive data between customers and securities companies, such as customer transaction data, customer operation behavior, and customer browsing records. Information systems are becoming more and more complex, and electronic data is easy to delete and tamper with. When a customer disagrees with the data, it is difficult for securities companies to prove that their data is credible, and it is difficult to protect the legitimate rights and interests of customers. [0003] Under normal circumstances, a variety of interactive data occurs between a client and a securities company, and the securities company directly stores the interactive data in the data...
