Controllable anonymous voting system based on blockchain and decentralized traceable attribute signature

Abstract

The invention belongs to the field of electronic voting, in particular to a controllable anonymous voting system based on block chain and decentralized traceable attribute signature. The system of the present invention includes a controllable anonymous authentication module, a decentralized voting module, a user module and a block chain module; the controllable anonymous authentication module provides users with anonymous authentication services and generates attribute private keys. Recover the real identity information of relevant users; the decentralized voting module is responsible for the specific voting operations of users, including verifying the legitimacy of voting users and statistics of final voting results; the user module is responsible for maintaining the relevant identity information of users; the blockchain module is responsible for The specific data is uploaded to the chain to ensure the authenticity and immutability of the voting data. The present invention solves the problems of voting authenticity and user privacy protection commonly existing in the existing electronic voting system, and protects the user's identity privacy information to the greatest extent on the premise of ensuring that the voting is authentic, effective and verifiable.

Description

technical field [0001] The invention belongs to the technical field of electronic voting, and in particular relates to a controllable anonymous voting system based on block chain and decentralized traceable attribute signature. Background technique [0002] With the continuous progress of the society and the rapid development of the economy, polling surveys have played an increasingly important role in social life. From the political work of the government to the investigation and development of enterprises, voting activities can be seen everywhere. However, there are various problems in the traditional offline voting method, which cannot keep up with the pace of social development: 1) Offline voting requires staff to participate in the organization, and space and time are limited; 2) Ballots for offline voting need to use a large number of Paper causes waste of resources; 3) Offline voting makes the post-vote counting process take a lot of time and energy, and manual count...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a controllable anonymous voting system based on blockchain and decentralized traceable attribute signature, and solve the problem of existing electronic voting by combining blockchain with decentralized traceable attribute signature technology. The authenticity of votes in the system cannot be guaranteed and the privacy of voters is leaked. While conducting controllable anonymous authentication of voters, the authenticity, validity and verifiability of votes are guaranteed.
