Abstract

The invention relates to a data processing method, apparatus and device based on a block chain, and a storage medium. The method comprises the steps of receiving event data generated by a user terminal for a service event; generating a first event block of the event data; acquiring a second event block associated with the first event block, wherein the second event block has a block encryption value; generating a block encryption value of the first event block by using the block encryption value of the second event block; and encrypting the first event block by using the block encryption valueof the first event block. Through adoption of the method, the event data recording the service event is not tampered due to use of the block chain technology, so that the event data recording the service event has non-repudiation and legal validity.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a data processing method, device, computer equipment and storage medium based on blockchain. Background technique [0002] During the operation of an enterprise, business events such as business negotiations and technology research and development may occur. Generally, users can record business events in the form of text, audio, video, etc. Data such as text, audio, video, etc. can be stored in the internal server of the enterprise. [0003] However, the data stored on the server of the enterprise may have data security risks. For example, illegal users may invade the enterprise's server to tamper with research and development data. Enterprises may suffer serious losses due to data tampering or data destruction. [0004] Therefore, the data processing method for business events in the prior art has the problem that data security cannot be guaranteed. Contents o...
