Abstract
The present application discloses a data exchange system, method, and device. The system comprises a first server configured to acquire a to-be-exchanged data identifier based on requirement information; store the to-be-exchanged data identifier; acquire a storage address of the to-be-exchanged data identifier; and encrypt the storage address of the to-be-exchanged data identifier to generate a first encrypted storage address; and a second server configured to acquire the first encrypted storage address from the first server; decrypt the first encrypted storage address to acquire the storage address of the to-be-exchanged data identifier; acquire the to-be-exchanged data identifier based on the storage address of the to-be-exchanged data identifier; and find to-be-exchanged data indicated by the to-be-exchanged data identifier from a pre-stored data set based on the to-be-exchanged data identifier, such that the first server acquires the to-be-exchanged data from the second server, the data set including data and a data identifier.
