Abstract

The invention belongs to the e-commerce technology field and discloses a modifiable reputation evaluation system and method based on a block chain, and an electronic payment system. A receipt from a seller is received by a user, the signature of the seller in the receipt is verified, and the evaluation information is generated; after verification is completed, a ring signature of the evaluation information is generated by the user, and the ring signature is sent to the block chain; the receipt and the ring signature of the user are verified by the block chain; a database is updated after the block is generated; a new signature is acquired by the user through a signature algorithm, and the new signature is sent to the block chain; validity of the signature is verified by the block chain, and whether the two signatures are completed by the same user is determined; a pointer corresponding to the block of a previous message is modified after verification completion, the previous message ismarked as invalid, and the previously-revoked information is replaced by the block of the message. The method is advantaged in that on the condition that user anonymity and transaction non-tamperability are guaranteed, integrity and openness of the evaluation information are guaranteed, and reliability of the evaluation information is guaranteed.
