Abstract
With the rapid development of the Internet of Things, cell phones inevitably involve people’s privacy and property information. Therefore, ensuring cell phone security is of great importance. Current cell phone protection methods include cell phone anti-theft and identity authentication, but each has limitations. Cell phone anti-theft methods focus on preventing cell phone loss but do not adequately address privacy security. Identity authentication emphasizes privacy protection but overlooks the cell phone’s security. Previous studies have achieved these two methods through ultrasonic or sensors. However, ultrasonic-based methods are limited by sensing distance and are inconvenient to use. Sensor-based methods do not detect subtle movements and may have shortcomings in terms of security. This study proposes an ultrasonic and sensor fusion-based persistent cell phone protection method integrating anti-theft and identity authentication. Unlike past work, this study uses ultrasonic and inertial sensors to capture motion data of users with different granularity, and provide multifaceted protection for cell phones through anti-theft when taking up the cell phone (ATWTP) and gait identity authentication (GTIA). Our intuition in the design is that each individual has unique movements and gait patterns, resulting in differences in the collected data from ultrasonic and inertial sensors. These differences can be used to achieve persistent protection of the cell phone. This study combines the strengths of sensors and ultrasonic through multimodal fusion and designs a system that incorporates system-triggered event detection (STED), ATWTP, and GTIA. The results demonstrate that the proposed design achieves an accuracy of 96.88% in protecting cell phones.
