Complex event processing and distribution of dependent event streams
Avais Mirza, Anshul Manek, Ankita Naik · 2015
Existing event processing systems provide insufficient privacy constraints for preserving data. There may be prob - lem in large-scale distributed applications like a logistic chain where event processing operators may be spread over multiple security domains. One can identify from outgoing event streams confidential input streams of the event processing system. We present a fine- grained access management for complex event processing. We can specify of an access policy to protect each incoming event stream also enforced by algorithms for access consolidation. We provide a measure in a scalable manner to increase the utility of the event processing system for the perplexity of event streams. A perplexity threshold as part of the access policy allows ignoring access requirements and delivering events which have achieved a sufficient high obfuscation level.
