摘　　要：计算机科技的崛起给人们带来了很多的便利,但与此同时,网络安全面临着前所未有的挑战。以满足未来更高级别安全能力为出发点,提出了一种新型的基于区块链的抗泄露认证数据分享方案。在互联网企业之间分享用户信息的过程中,用户信息易被窃取或篡改,其中公司内部员工有意或无意泄露敏感数据尤为严重,影响到信息作为资产进行统一安全共享的效率,为此,本文使用信息负表示进行信息共享,结合区块链的去中心化、开放性、难以篡改的技术特征,并利用运行在区块链上的智能合约降低公司信任成本,解决上述问题,提高工作效率,同时推动社会发展智能化。The rise of computer science and technology has brought a lot of convenience to people, but at the same time, network security faces unprecedented challenges. In order to meet the higher level of security capability in the future based on block chain, we design a new anti-leaked authentication data sharing scheme in this paper. For the process of data sharing between internet enterprises, user s information is easily stolen or tampered. In particular, employees in the company leak user s sensitive data unintentionally or intentionally. These behaviors affect the efficiency of data asset sharing. For this reason, this paper uses the negative representation of information to share information. Based on the character of decentralization, openness, difficult to-change, and using the smart contract in the blockchain to reduce costs, solve all problems, improve work efficiency and promote social development of the intelligent.
