step S600, the data disclosing party sends encrypted sustainable information disclosing data blocks, the data receiving party receives the encrypted data and then decrypts the encrypted data by using a private key, and the data receiving party sends information of finishing the data request to the checking party to finish the access of the sustainable disclosing data: the data disclosure party initiates an encryption transmission channel with the data receiving party and sends an encryption sustainable information disclosure data block to the data receiving party, after the transmission of the encryption sustainable information disclosure data block is completed, the data disclosure party and the receiving party decrypt the sustainable information disclosure data block by adopting a private key of a key pair by the data receiving party and verify the integrity of the decrypted sustainable information disclosure data block, the data receiving party sends information of finishing the data request to the checking party, and the verifying party records the data disclosure record.
2. An electronic device, the electronic device comprising:
at least one processor; the method comprises the steps of,
a memory communicatively coupled to the at least one processor; wherein,
the memory stores instructions executable by the at least one processor to enable the at least one processor to perform the method of claim 1.
3. A non-transitory computer readable storage medium storing computer instructions for causing the computer to perform the method of preceding claim 1.
