Abstract: Traditional informationsharing solutions typically rely on data center servers for data storage and verification. However, this centralized model is vulnerable to issues such as data tampering, privacy breaches, and operational irregularities when under attack, making it difficult to meet the requirements for data trustworthiness. To address these challenges, this paper proposes a solution that combines blockchain technology with biometric information authentication. By using biometric features such as fingerprints and facial recognition to generate a unique authentication key, which is securely stored on the blockchain, the solution leverages the decentralized, tamperproof, and traceable characteristics of blockchain to ensure secure data storage and trusted sharing, thereby effectively safeguarding privacy and security during the information verification process. Taking the education sector as an example, this solution can effectively address issues like exam cheating and resource infringement, providing a new approach to data security and sharing that also ensures privacy protection.

摘要： 传统的信息共享方案通常依赖数据中心服务器进行数据存储和验证，但这种集中化模式易在遭受攻击时出现数据篡改、隐私泄露以及操作不规范等问题，难以满足对数据可信性的要求.针对这些挑战，提出了一种结合区块链技术与生物特征信息认证的解决方案.通过指纹、面部识别等生物特征信息生成唯一的认证密钥，并将其安全地存储在区块链上，充分利用区块链的去中心化、不可篡改及可追溯特性，实现数据的安全存储和可信共享，从而有效保障信息验证过程中的隐私性与安全性.以教育领域为应用场景，该方案能够有效解决考试作弊和资源侵权等问题，为数据安全与共享提供了一种兼顾隐私保护的新思路.
