Description
Summary:B2B (business-to-business) systems often use service-oriented architecture (SOA) with decomposed business services. These services can interact and share data among each other. Service might use a cloud - hosted database, such as a non - relational encrypted key - value store. However, the cloud platform hosting the database can be untrusted. Data owner needs to be sure that each service can access only those segments of a shared database for which the service is authorized. Furthermore, data requests can come from a service also hosted by untrusted cloud. Hence, there is a need for designing a cloud enterprise framework that can ensure privacy-preserving data dissemination in SOA and accurately detect data leakages. We design and prototype a solution that ensures privacy - preserving dissemination of data. The solution is based on (a) role-based access control, (b) cryptographic capabilities of client's browser, (c) authentication method, (d) subject's trust level. The prototype enables privacy - preserving dissemination of Electronic Health Records (EHRs) hosted in an untrusted cloud.
