C 2016 Anupam Das UNDERSTANDING and MITIGATING the PRIVACY RISKS of SMARTPHONE SENSOR FINGERPRINTING
c 2016 Anupam Das UNDERSTANDING AND MITIGATING THE PRIVACY RISKS OF SMARTPHONE SENSOR FINGERPRINTING BY ANUPAM DAS DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Computer Science in the Graduate College of the University of Illinois at Urbana-Champaign, 2016 Urbana, Illinois Doctoral Committee: Associate Professor Nikita Borisov, Chair Associate Professor Matthew Caesar Associate Professor Romit Roy Choudhury Assistant Professor Paris Smaragdis Professor Dan Boneh, Stanford University ABSTRACT The widespread use of smartphones in our everyday life gives rise to pri- vacy concerns. Fingerprinting smartphones can jeopardize user privacy by enabling remote identification of users without users' awareness. In this dissertation we study the feasibility of using onboard sensors such as micro- phones, accelerometers and gyroscopes to fingerprint smartphones. During fabrication, subtle imperfections arise in device sensors which induce distinc- tive anomalies in the generated signal. Using machine learning techniques we can distinguish smartphones generating such distinctive anomalies. We first look at fingerprinting smartphones through onboard microphones and speakers. We explore different acoustic features and analyze their ability to successfully fingerprint smartphones. Our study identifies the prominent acoustic features capable of fingerprinting smartphones with a high success rate, and also examines the impact of background noise and other variables on fingerprinting accuracy. Next, we surreptitiously fingerprint smartphones us- ing the imperfections of motion sensors (i.e., accelerometers and gyroscopes) embedded in modern smartphones, through a web page. We analyze how well motion sensor fingerprinting works under real-world constraints by col- lecting data from a large number of smartphones under both lab and public environments. -

The research leading to these results has received funding from the European Union’s Horizon 2020 research and innovation programme under Grant Agreement No. 856726 (GN4-3). Abstract Many research projects need to transfer large amounts of data and use specialised Data Transfer Nodes (DTNs) to optimise the efficiency of these transfers. In order to help NRENs to better support user communities who seek to move large volumes of data across their network, a DTN Focus Group was set up in the Network Technologies and Services Development work package (WP6) of the GN4-3 project, which has performed several activities around DTN deployment, the results of which are summarised in this document.
