Abstract
A data provider encrypts source data to obtain a ciphertext of the source data, and uploads the ciphertext of the source data to a data storage platform for storage. Subsequently, in response to a data application request of a data consumer, the data provider encrypts a storage address of the ciphertext of the source data by using a public key of the data consumer, and uploads the encrypted storage address to a blockchain network. The data consumer obtains the ciphertext of the source data from the data storage platform. In the process, a blockchain decentralization capability is used to implement secure and trusted data exchange by using a smart contract that is public and commonly visible to a plurality of parties.
