Trustworthy Data Collection in a Smart Environment
Guoxi Wang, UCI
11:00am, Zoom (link to be sent via email) [Host: Scott]

Contemporary IoT environments, such as smart buildings, require end-users to trust data-capturing rules published by the systems. There are several reasons why such a trust is misplaced --- IoT systems may violate the rules deliberately, or IoT devices may transfer user data to a malicious third-party due to cyberattacks, leading to the loss of individuals' privacy or service integrity. To address such concerns, we propose a framework to ensure trust in IoT systems and applications. The framework, named IoT Notary, provides secure log sealing on live sensor data to produce a verifiable `proof-of-integrity,' based on which a verifier can attest that captured sensor data adheres to the published data-capturing rules. IoT Notary is an integral part of TIPPERS, a smart space system that has been deployed at UCI to provide various real-time location-based services. IoT Notary imposes little overheads for verification; thereby, users can verify their data of one day in less than two seconds. 

Guoxi Wang received his B.S. in Information Security at Wuhan University in China and M.S. in Networked Systems at UCI. He joined the Networked Systems Ph.D. program in 2016 and has been a member of Distributed System Middleware (DSM) Group and Information System Group (ISG), working with Prof. Nalini Venkatasubramanian and Prof. Sharad Mehrotra. His research interests include the privacy and security issues in the Internet of Things (IoT) and Edge Computing.
