摘　　要：企业征信需要从多个异构的征信数据源机构中获取,要考虑机构之间数据共享的安全性、可信性和便利性。现有的多方安全计算和联邦学习不能完全适合招投标等领域的企业征信数据共享。马赛克数字卡片能够承载征信需求方、被调查企业、征信数据提供方等多方的数据,结合区块链智能合约技术,打造企业征信数据多方可信计算框架,可以应用于在线招标投标企业的征信数据共享与审核,为未来高效的数据可信交换提供了扩展空间。Enterprise credit information needs to be obtained from multiple heterogeneous credit data source institutions,and the security,credibility and convenience of data sharing among institutions should be considered.Existing multi-party secure computing and federated learning are not fully suitable for enterprise credit data sharing in such fields as bidding.Mosaic digital cards can carry the data of multiple parties such as credit demanders,investigated enterprises and credit data providers,and combined with blockchain smart contract technology to create a multi-party trusted computing framework for enterprise credit data can be applied to credit data sharing and auditing of online bidding enterprises,which provides an expansion space for efficient data trusted exchange in the future.
