Publication number: 20230362199Abstract: Example embodiments of the present disclosure relate to dynamic authorization. According to embodiments of the present disclosure, a solution for dynamic access control to data is proposed. On receiving data registration from a data source, a first device checks the data types to be produced by the data source and adds policies for the data or updates existing policies for the data according to its property. It also serves as access control decision point to determine consumers' access rights based on centrally managed policies. Authorization for data access is granted/denied according to local attributes/policies. In this way, it achieves a dynamic, context-aware and risk-intelligent access control to different kind of data from various data sources (i.e., service producers).Type: ApplicationFiled: October 9, 2020Publication date: November 9, 2023Inventors: Iris ADAM, Jing PING, Konstantinos SAMDANIS, Chaitanya AGGARWAL, Anja JERICHOW
