Abstract

The invention discloses a privacy protection transaction method based on a blockchain technology in electronic commerce. The method comprises the following steps that: adopting the blockchain technology which comprises a privacy smart contract and a zero-knowledge proof to protect the private information of a user; taking the privacy smart contract as a bridge between a buyer and a seller in a transaction period; adopting the zero-knowledge proof to issue a confidentiality token and create a confidentiality transaction; and combining the blockchain, an industrial data space and the Internet ofThings technology to establish infrastructure, and establishing an integrated platform for logistics business management in a distribution way. By use of the method, private information can be hiddenfor dispatchers, private information, including, identity, address, telephone number and the like, can be hidden for sellers, in addition, the method also can be used for other blockchain applicationscenes with a data privacy protection requirement, in addition, blockchain characteristics can be fully utilized, and therefore, the evaluation problem of an electronic commerce platform can be improved.
