Embodiment Construction

[0038] Blockchain (Block Chain) is a chained data structure that combines data blocks in a sequential manner in chronological order, and cryptographically ensures that data cannot be tampered with and cannot be forged. Distributed ledgers. Multiple independent distributed nodes (that is, blockchain node devices) keep the same records. Blockchain technology realizes decentralization and becomes the cornerstone of credible digital asset storage, transfer and transaction.

[0039] by figure 1 The structural diagram of the block chain shown as an example, whenever new data needs to be written into the block chain, these data will be aggregated into a block (block), added to the end of the existing block chain, through consensus The algorithm ensures that the newly added blocks of each node are exactly the same. Several transaction records are recorded in each block, which also contains the hash value of the previous block. All blocks save the hash value of the previous block in ...

Abstract

The embodiment of the invention discloses a data processing method and device based on a block chain and a storage medium. The method comprises the following steps: receiving encrypted multimedia datasent by terminal equipment, obtaining a public key of a user corresponding to the terminal equipment in a block chain corresponding to a block chain network, and decrypting the encrypted multimedia data based on the public key to obtain multimedia data to be processed; and performing endorsement verification on the to-be-processed multimedia data in the trusted computing environment to obtain endorsement verification information for the to-be-processed multimedia data, performing digital signature on the endorsement verification information, and performing uplink processing on the endorsementverification information with the digital signature. Third-party verification of the to-be-processed multimedia data can be realized through the block chain technology, so that the third-party verification process and the verification result are more public and transparent, the verification result is prevented from being tampered, and the processing risk of subsequent data processing through theto-be-processed multimedia data is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a blockchain-based data processing method, device and storage medium. Background technique [0002] With the continuous development of Internet technology, a large number of offline data processing processes can be transformed into online data processing processes. For example, users can scan paper documents or documents into electronic files, convert them into multimedia data, and submit them for data processing. The platform executes the online processing process through the data processing platform. Alternatively, it is also possible to directly input or fill in the multimedia data through the data processing platform and execute the online processing flow. [0003] If there is a problem with the multimedia data itself in the above-mentioned online processing flow, it may seriously affect the business processing corresponding to the online processing flow, and...
