Embodiment Construction

[0056] As mentioned in the background, the existing data sharing platform can receive and store the data uploaded by various institutions on the one hand, and provide data query services to each institution on the other hand. However, there are two problems with this model: First, because the data shared by various institutions is stored by a centralized data sharing platform, if someone maliciously tampers with the data stored on the platform, the data that each institution can query from the platform is Untrustworthy; second, the data sharing platform often receives data query requests sent by multiple institutions at the same time, and the data sharing platform has limited processing capabilities for data query requests (need to review the authority of each institution requesting data query), As a result, some institutions need to wait in line, and it takes a long time to query data, and the efficiency of querying data is low.

[0057] For this reason, in the embodiment of ...

Abstract

Embodiments of the invention disclose a data storage method and apparatus, and a data query method and apparatus. Each institution serves as a block chain node to form a block chain network. For any block chain node, on one hand, the block chain node can send data to an encryption device for performing encryption and receive encrypted data returned by the encryption device, the encrypted data is sent to each block chain node for consensus verification, and the encrypted data passing the consensus verification is stored in a block chain; and on the other hand, through an intelligent contract, the block chain node only can obtain the data in a permission range from the block chain.

Description

technical field [0001] This specification relates to the field of information technology, in particular to a data storage method, a data query method and a device. Background technique [0002] In the information age, data has value. For example, for a bank, if the user's purchase record can be obtained from the sales center, then the credit ability of the user can be better evaluated; and for the sales center, if the user's credit score can be obtained from the bank, then Different sales strategies can be adopted for different users. Obviously, in the above example, the bank and the sales center need to share data with each other. In fact, as the value of data becomes more prominent, more and more institutions want to share each other's data. [0003] At present, the data sharing platform is generally used as an intermediary. On the one hand, it receives and stores the data uploaded by various institutions, and on the other hand, it provides data query services to variou...
