Abstract
An anonymous disclose and many-to-many recognition system based on blockchain and identity confirmation allowance and a method thereof are disclosed. In the system, an exposing host generates a one-time address and encrypt the disclosure data into the encrypted data, write the encrypted data into the blockchain; an identity confirmation host generates a valid flag, and an announcement host decrypts the encrypted data to generate a corresponding receipt flag, and garbles a correspondence between the decrypted disclosure data and the corresponding one-time address, to generate and write a shuffled recognition announcement to a blockchain, so that when the exposing host detects the presence of the self-owned disclosure data and one-time address in the shuffled recognition announcement, the exposing host writes a recognition flag into the blockchain. Therefore, the technical effect of improving anonymity and allowing identity confirmation can be achieved.
