Problems solved by technology

[0003] The blockchain has the characteristics of value transfer, decentralization, and non-tampering. The blockchain can be applied to data transactions, financial payments and other fields. For transaction data and other data that needs to be stored in the blockchain, the data needs to be encrypted. To prevent data leakage, however, some data can only be authorized for some users to access, so the problem of how to isolate the data needs to be solved

Embodiment Construction

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0070] The embodiment of the present invention proposes a data processing method, which can be applied to the scene of data isolation for the target data that needs to be stored in the block chain. In this application, taking the transaction data as an example, after generating the transaction data , it is necessary to allow the associated users related to the transaction data to see the transaction data, or to authorize the associated users, such as the seller, the buyer and other users in the transaction business. Therefore, through the implementation steps of this solution, through the associated user's Attribute information encrypts transaction data, so that when associated users need to view or obtain transaction data, they can obtain or view transaction data through their...

Abstract

The embodiment of the invention discloses a data processing method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a first attribute information setthrough obtaining the attribute information of each associated user in at least one associated user of target data; encrypting a first attribute information set and the target data according to a preset algorithm to obtain a first ciphertext, and uploading the first ciphertext to a block chain; furthermore, when the first user needs to access the target data, in response to a data access request of the first user, the first ciphertext is decrypted according to the first attribute information of the first user to obtain a decryption result, and the data access request comprises the first attribute information, so that data isolation can be realized by associating the attribute information of the user.

Description

technical field [0001] The present invention relates to the field of Internet technology, specifically to the field of payment technology, and in particular to a data processing method, device, computer equipment and storage medium. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain (Blockchain), essentially a decentralized database, is a series of data blocks associated with each other using cryptographic methods. Each data block contains a batch of network transaction information, which is used to verify its Validity of information (anti-counterfeiting) and generation of the next block. [0003] The blockchain has the characteristics of value transfer, decentralization, and non-tampering. The blockchain can be applied to data transactions, financial payments and other fields. For transaction data and other data ...
