Abstract

The embodiments of the present disclosure disclose a blockchain-based trusted data exchange method, apparatus, terminal device and medium. A specific implementation of the method includes: receiving a storage record table sent by the first terminal; sending the storage record table to the second terminal; receiving an access request sent by the second terminal; sending the access request to the first terminal; receiving The set of ciphertext data and public key sent back by the first terminal; send the set of ciphertext data and public key to the second terminal; delete the ciphertext data; update the blockchain. In this embodiment, the first terminal publishes the storage record table to the blockchain to meet the storage capacity requirement of the blockchain. The first terminal encrypts the target data and sends it to the chain. The blockchain sends the encrypted data and the public key set to the second terminal and destroys the ciphertext data on the chain, and the second terminal generates the target encrypted data according to the encrypted data and the public key set. In the data exchange process, only the first terminal has the target data, which improves the level of trusted data exchange.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of blockchain, and in particular, to a method, apparatus, terminal device, and computer-readable medium for exchanging trusted data. Background technique [0002] Blockchain technology is an emerging technology in the field of information technology, and it is the basis for building the Internet of Value. It is an information technology that integrates multiple technologies including distributed data storage, peer-to-peer network, and cryptography. It has the characteristics of decentralization, openness, and autonomy. Its decentralized trust nature provides us with a viable solution for fair exchange of data. At the same time, its distributed storage and the characteristics that data is not easily tampered are also very suitable for designing secure data sharing solutions. [0003] However, when data exchange and sharing based on blockchain, there are often the following technical problems: ...
