A Decentralized Service-Platform Towards Cross-Domain Entitlement Handling

Description

As our world is becoming increasingly connected, secure and seamless cross-domain access to heterogeneous services is becoming more and more important. However, coop- eration between client-server based systems in the sales domain is often difficult to achieve due to a lack of standardization as well as limited trust between service providers. Furthermore, the demand for anonymization techniques is becoming more important due to tighter regulations and increased privacy awareness of users. This is especially relevant when data needs to be shared by several parties. In this paper we describe a software service platform designed to increase collaboration between different cross-domain services. The general idea is to provide a common trusted layer for existing client-server systems that can be used for anonymizing and sharing services in the form of digital entitlements across independent service providers, their systems, and users, while ensuring secure authentication and authorization. Furthermore, we leverage the tamper-resistant properties of the blockchain and smart contracts in order to protect sensitive transactions against fraudulent manipulation and to introduce service-based agree- ments to the overall system.
