With the growing number of personal safety incidents, especially those of women, elderly and youngsters, and traveling alone, mobile safety systems become increasingly important. Existing solutions have several problems, like requiring an internet connection to send request to the back- end server, can cancel the safety request and activate the safety request with one trigger, and can cancel the safety request in unintended or malicious way. As such, the state-of-the-art solutions cannot deliver the best user experience when the user is panicked, or in low connectivity area, or fails to cancel the safety request. In this paper, we propose EchoGuard, a mobile safety system that addresses the human reliability problem with a novel combination of (1) multi-trigger-based activation and cancellation, (2) effective offline-first communication, and (3) biometric-secured cancellation.The present invention is directed to a rapid response personal safety system. The personal safety system has a mobile device application activatable by four independent emergency triggers. Four independent triggers comprises a voice codeword recognition trigger, a shake trigger, a hardware button sequence trigger and a manual application activation trigger. Four independent triggers are used to provide redundancy to enable activation for a wide range of different situational contexts. In the activation a pre-alert period of 15 seconds is started. During the pre- alert period the mobile device vibrates continuously and alarms. The application is canceled during the pre-alert period using user fingerprint. If the application is not cancelled during the pre-alert period an SMS alert is sent to 3 pre-defined emergency contacts. Auto-call is started to a primary emergency contact that continues until that person take the call.This paper describes the design, implementation, and evaluation of EchoGuard, a voice over IP and cellular voice-network based communication application for automated emergency reporting. EchoGuard is designed with an offline-first system design, making it very easy use in remote areas or low-connectivity locations where network services are not available. EchoGuard sends SMS and auto calling for data transfer, and is able to function on a locked device. EchoGuard provides biometric authentication to avoid unwanted alert cancellation. In our observation, evaluate the EchoGuard system and provide comparative results with existing mobile safety applications. We observe that EchoGuard can be activated quickly, provides secure alert cancel, and can maintain communication in different situations, such as device lock, high stress, and low connectivity.This paper introduces the EchoGuard mobile safety response system that responds to safety incidents using a multi-modal trigger system. This paper refers that multi-modal triggers, biometric cancellation, and continuous communication should be used to enhance mobile safety responses. EchoGuard is the first system to combine these techniques to address several key gaps in existing mobile safety. EchoGuard is not limited to women's safety. It can be used with children, the elderly, traveling alone, and individuals who work in high-risk occupations. EchoGuard includes unique pathways to answer calls, offline communication, and biometric-secured authentication for trusted contacts. This paper introduces a mobile security system that combines a variety of activation pathways with continuous communication to create a practical, real-world, and quick response to emergencies.
