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.
增强手机安全性:基于超声波和传感器融合的持久性手机保护方法,集防盗和身份验证于一体
随着物联网的快速发展,手机不可避免地会涉及到人们的隐私和财产信息。因此,确保手机安全显得尤为重要。目前的手机保护方法包括手机防盗和身份验证,但每种方法都有其局限性。手机防盗方法侧重于防止手机丢失,但没有充分解决隐私安全问题。身份验证强调隐私保护,但忽略了手机的安全性。以往的研究通过超声波或传感器实现了这两种方法。然而,基于超声波的方法受到感应距离的限制,使用不便。基于传感器的方法无法检测到细微动作,在安全性方面可能存在缺陷。本研究提出了一种基于超声波和传感器融合的持久性手机保护方法,集防盗和身份验证于一体。与以往的研究不同,本研究利用超声波和惯性传感器捕捉不同粒度的用户运动数据,并通过拿起手机时的防盗(ATWTP)和步态身份验证(GTIA)为手机提供多方面的保护。我们在设计中的直觉是,每个人都有独特的动作和步态模式,从而导致从超声波和惯性传感器收集到的数据存在差异。这些差异可用于实现对手机的持久保护。本研究通过多模态融合将传感器和超声波的优势结合起来,并设计了一个包含系统触发事件检测(STED)、ATWTP 和 GTIA 的系统。结果表明,所提出的设计在保护手机方面达到了 96.88% 的准确率。
