Full anonymous feedback method based on block chain

Abstract

The invention discloses a full anonymous feedback method based on a block chain, which comprises the following steps that: 1) a feedback person submits an answer sheet, a system writes answer sheet information into an intelligent contract, and adds a random number uuid to generate m; 2) the feedback person blinds the m and sends the m to an organizer; 3) the organizer obtains the blinded information m ', signs the m' after confirmation to obtain s', and returns the s' to the feedback person; 4) the feedback person verifies the validity of the s' to the intelligent contract; 5) if the s' is verified to be valid, the feedback person removes blindness of the s' to obtain s, a new address is randomly generated, and uuid, m and s are sent to the intelligent contract; if the s' check is invalid,the step 2) is executed; 6) the smart contract verifies s, m and uuid, invalid results are filtered, and if s is valid and uuid is not repeated, the answer sheet is valid, and 7) the organizer inquires a feedback result from the smart contract. According to the method, it is ensured that the information of the feedback person is not leaked, the feedback person truly has the feedback right, the one-ticket multi-investment phenomenon is prevented, and the method is a set of anonymous guarantee process.

Description

technical field [0001] The invention relates to the field of block chains, and relates to a fully anonymous feedback method based on block chains. Background technique [0002] The electronic voting system refers to voting electronically, and also refers to a method of counting votes electronically. The continuous improvement of information technology has led to more active applications of electronic voting systems. Online voting converts ballot information into digital formats in physical space, and administrators can manage and operate in cyberspace without being limited by time and space. , It is also convenient for the dissemination and promotion of the system. Compared with traditional voting, electronic voting has the advantages of fast and accurate counting, saving manpower and expenses, and ease of use of voting. However, there are still diversification of voting management and service requirements, and the expansion of the system scale, along with the objectivity ...

AI Technical Summary

Problems solved by technology

This system cannot prevent the mandatory disclosure of voting information due to the application of blockchain technology, so it is necessary to design a feedback system that allows the organizer to decide whether to disclose the feedback results

[0005] Fan Hongbo proposed a credible electronic voting method based on blockchain technology, which applied the secure multi-party computing protocol to voting and counting. The voting system has verifiability and no receipt. Under the premise of ensuring voting security and credibility, at the same time, in the existing electronic voting system, it is widely relied on trusted third parties to complete the registration and authentication stage. If the registration center is dishonest, the voting will fail.

By combining blockchain technology with electronic voting technology, using MIT's Enigma blockchain project-related technology, the certification registration center is canceled, the dependence of electronic voting on trusted third parties is stripped, and the trust of voters and candidates is eliminated. Privacy plays a protective role, but it cannot avoid the occurrence of multiple votes for one vote, and the organizer uses multi-key signatures to calibrate the respondent. Therefore, it is necessary to design a voting that prevents multiple votes and strictly encrypts the feedback information. system
