The invention realizes a decentralized identity system with uniqueness and key security, and belongs to the technical field of block chain application. Different from an early decentralized digital identity system which only issues a certificate by a certificate issuing mechanism, the system realizes certificate issuing by using the legacy data of the existing Web server, and ensures the uniqueness of certificate issuing by using the committee node. And meanwhile, the system has a user key recovery function, and the private key of the user can be retrieved after being lost, so that the system has key security. Compared with an existing decentralized identity system, the system has good safety and adaptability. 本发明实现了一种具有唯一性以及密钥安全的去中心化身份系统，属于区块链应用技术领域。不同于早期的去中心化数字身份系统仅由凭证颁发机构发布凭证，该系统实现了利用现有Web服务器的遗留数据颁发凭证，并利用委员会节点保证凭证颁发的唯一性。同时该系统具有用户密钥恢复功能，用户的私钥在丢失后可以找回，使系统具有密钥安全性。对比现有的去中心化身份系统，本系统具有良好的安全性和适应性。
