Abstract

Privacy and security in the context of the streaming systems largely have been overlooked. We now tackle this important problem in this paper. Our work focuses on contextaware security and user-centric privacy preservation in data stream management systems (DSMS) by exploiting security constraints (called security punctuations) that are dynamically embedded into data streams. The novelty of our proposed approach is that access control policies are not persistently stored in the DSMS but rather streamed together with the data. We present novel query operators, termed Security Shield (SS) and Security-Compliant Join (SCJoin) that are designed to make queries comply with the security policies of the streaming data while still guaranteeing near real-time response. As a proof of feasibility, we have implemented the security punctuation framework within a real DSMS. Our experimental results show that our proposed solution incurs low overhead.
