Proceedings - International Conference on Data Engineering : 1495-1498. ScholarBank@NUS Repository. https://doi.org/10.1109/ICDE.2009.25||Abstract:||In this demo proposal, we illustrate ACStream, a system built on top of StreamBase , to specify and enforce access control policies over data streams. ACStream supports a very flexible role-based access control model specifically designed to protect against unauthorized access to streaming data. The core component of ACStream is a query rewriting mechanism that, by exploiting a set of secure operators proposed by us in , rewrites a user query in such a way that it does not violate the specified access control policies during its execution. The demo will show how policies modelling a variety of access control requirements can be easily specified and enforced using ACStream. © 2009 IEEE.||Source Title:||Proceedings - International Conference on Data Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/41572||ISBN:||9780769535456||ISSN:||10844627||DOI:||10.1109/ICDE.2009.25|
