Problems solved by technology

[0007] Aiming at the defects or improvement needs of the existing network questionnaire survey process, the present invention provides a questionnaire survey method based on zero-knowledge proof and blockchain, which aims to solve the problem that user identity information will be leaked during the existing network questionnaire survey process, And the user may not fill in the questionnaire truthfully due to the possibility of identity information being leaked

Embodiment Construction

[0038] The present invention proposes a questionnaire survey method based on zero-knowledge proof and blockchain, and the specific implementation process is as follows:

[0039] S1. The survey initiator designs a questionnaire, including questionnaire topics, topic types, topic options, etc., and generates a questionnaire at the same time;

[0040] S2. The survey initiator uploads the questionnaire to the blockchain (Ethereum), and all users can view the questionnaire;

[0041] S3. The survey initiator interacts with the surveyed users. The survey initiator determines the users who can participate in the survey. The users who participate in the survey need to provide the initiator with a uid that identifies their identity information. The uid can be arbitrary. Anyone who participates in the survey can use a new key to regenerate a uid;

[0042] S4. The initiator uploads the user uids that can participate in this survey to the blockchain;

[0043] S5. The user obtains the use...

Abstract

The invention belongs to the technical field of network questionnaire survey, and particularly relates to an anonymous questionnaire survey method based on zero knowledge proof and a block chain. Unbinding of the user identity and the questionnaire filled by the user identity is achieved through zero knowledge proof, an investigation initiator cannot obtain the user information through the submitted questionnaire, and the purpose of hiding the identity information of the investigated user is achieved. And meanwhile, the verification contract deployed on the block chain can ensure that only theuser passing the auditing can submit an effective questionnaire. The processes of questionnaire publishing, questionnaire submitting and the like are deployed on the block chain in a smart contract mode, so that the finally counted questionnaire result is public and credible.

Description

technical field [0001] The invention belongs to the technical field of network questionnaire survey, and in particular relates to an anonymous questionnaire survey method based on zero-knowledge proof and blockchain. Background technique [0002] Questionnaire survey, also known as questionnaire or inquiry form, systematically records the survey content by asking questions. Questionnaires come in many forms: tabular, card, and notebook. There are several advantages of questionnaire survey. One of the advantages of the questionnaire method is that it can save time, manpower and physical strength. Second, the results of the questionnaire survey are easier to quantify. Questionnaire survey method is a structured survey method. The form of survey, the sequence of questions, and the giving of answers are all fixed and expressed in words. Therefore, this method is easy to quantify. Third, the results of the questionnaire survey method are easier to statistically process and an...
