Data protection assumes a pivotal role in the era of the Internet, given that numerous applications enable users to communicate and access online services. Anonymous identity verification system(AIV) is a system designed to effectively manage user identities while safeguarding their privacy. This system empowers users to verify their identities without revealing their actual personal information. Furthermore, AIV facilitates the disclosure of minimal identifiers while preserving selective confidentiality. However, the allure of anonymity also provides an incentive for malicious users to breach system rules and engage in illicit activities, as their true identities remain concealed. Traditional AIV systems rely on an identity provider (IP) for user identity verification. This approach records the actual identities of all users and allows for the tracking of malicious users. Consequently, user identity parameters are shielded out of all entities except IP address. Nonetheless, The privacy of individuals is jeopardized due to the authenticity of the IP address is not always guaranteed, and there is no assurance of the protection of user activity and private information. This article introduces a blockchain-based AIV scheme that empowers end-users for manage their identity parameters while keeping their true identities, including their IP addresses, confidential from all organizations. However, the system's consensus mechanism can aid in establishing the true identities of perpetrators in cases of rule violations. Security requirements for AIV are informally analyzed and confirmed using a game-based verification system. The core concept of this research revolves around the integration of zk-SNARK,zero knowledge sunnict non-iterative argument of knowledge a form of ZKP, Shamir’s threshold secret distribution Sharing, and various different secret coding approaches.
