    Abstract: A method for authorizing a blockchain data access on a blockchain platform includes: obtaining from a third-party institution a data access request containing a user ID of data access, a data scope, and a random number of a signature, which is generated by the third-party institution after receiving a random number sent by a client terminal and signing on the received random number; performing a verification on the random number of the signature and the data scope; and after the verification is passed, sending data ciphertext corresponding to the user ID to the third-party institution, such that the third-party institution decrypts the data ciphertext using a data secret key sent by the client terminal.
