Leveraging Imperfections of Sensors for Fingerprinting Smartphones

چکیده
Many applications tend to allow automated login by storing passwords/cookies on the smartphone. As an alternative, recently there have been efforts to fingerprint devices for identification and authentication [2]. Towards that end, we explore whether it is possible to fingerprint a smartphone using its built-in hardware sensors such as accelerometers. Smartphone accelerometers are based on Micro Electro Mechanical Systems whose structure introduces subtle idiosyncrasies due to the manufacturing process. Moreover accelerometer chips use Quad Flat Non-leaded or Land Grid Array packaging, another source of imperfections [1]. We propose SensorPrint to leverage such imperfections of sensors.

متن کاملA Robust Crowdsourcing-Based Indoor Localization System
WiFi fingerprinting-based indoor localization has been widely used due to its simplicity and can be implemented on the smartphones. The major drawback of WiFi fingerprinting is that the radio map construction is very labor-intensive and time-consuming. Another drawback of WiFi fingerprinting is the Received Signal Strength (RSS) variance problem, caused by environmental changes and device diver...

This paper presents a method that trains the WiFi fingerprint database using sensor-based navigation solutions. Since micro-electromechanical systems (MEMS) sensors provide only a short-term accuracy but suffer from the accuracy degradation with time, we restrict the time length of available indoor navigation trajectories, and conduct post-processing to improve the sensor-based navigation solut...
