Abstract:
Embodiments of the present invention provide a block chain-based user data authorization method, comprising: a first application client stores encrypted user data of user data into block chain databases by means of block chain nodes; generates authorization information in response to a request for obtaining the user data by a second application client; and instructs the second application client to obtain the authorization information, so that the second application client obtains the user data on the basis of the encrypted user data and the authorization information. According to the method, the encrypted user data is saved in the block chain databases, so that the encrypted user data is not tampered and real user data is not leaked; and the second application client obtains the user data on the basis of the authorization information and the encrypted user data, so that sharing of the user data between different applications is implemented while ensuring the security of the user data. Embodiments of the present invention further provide a block chain-based user data authorization apparatus, a medium, and a computing device.
