Abstract
A method of user data authorization based on blockchain includes: storing, by a first application client, encrypted user data of user data in a blockchain database through a blockchain node, generating authorization information in response to a request of acquiring the user data by a second application client, and notifying the second application client to obtain the authorization information such that the second application client obtains the user data based on the encrypted user data and the authorization information. The encrypted user data is stored in the blockchain database such that the encrypted user data cannot be tampered with and a leak of real user data is prevented. The second application client obtains the user data based on the authorization information and the encrypted user data.
