Security and Privacy for Real Time Video Streaming Using Hierarchical Inner Product Encryption Based Publish-Subscribe Architecture.

In this era of digitization, there are many applicationswhich can be used for sharing videos to a group ofpeople around the world in real time. During the acquisitionof real time data, many sensitive information also gets captured along. This poses a threat to privacy of data. In this paper, we consider the scenario of real time sharing of video from multiple sources to multiple end users through a secure publish subscribe architecture. We propose a system that provides a secure user profile based data privacy using Hierarchical Inner Product Encryption (HIPE) and a broker with anonymous pub sub architecture. System provides multiple levels of data access control to end users based on their roles so that they will be able to see only those videos for which they have access. In order to ensure secure communication, the broker publishes data on encrypted topic and uses HIPE for data subscription. In this paper, we demonstrate the end-to-end working of the system through prototype implementation. Further, we also present the system performance and evaluate the system security both with and without HIPE.
