跨域数据授权运营研究及应用.

With the development of big data and cloud computing, data management is breaking down "data silos" and developing from isolated services for single domain to cross-domain data sharing and collaborative services. Based on the public data authorization and operation framework, this paper presented the full-link structure of cross-domain data authorization and operation, and discussed the challenges of data privacy and efficiency in the cross-domain data processing. In response to these challenges, two data processing models, centralized and privacy computing, were proposed, which could improve data processing efficiency while protecting data privacy. Finally, an application case of a cross-domain data authorization operation platform in a practical scenario was given. [ABSTRACT FROM AUTHOR]
