A Home Security System Based on Smartphone Sensors

Several new smartphones are released every year. Many people upgrade to new phones, and their old phones are not put to any further use. In this paper, we explore the feasibility of using such retired smartphones and their on-board sensors to build a home security system. We observe that door-related events such as opening and closing have unique vibration signatures when compared to many types of environmental vibrational noise. These events can be captured by the accelerometer of a smartphone when the phone is mounted on a wall near a door. The rotation of a door can also be captured by the magnetometer of a smartphone when the phone is mounted on a door. We design machine learning and threshold-based methods to detect door opening events based on accelerometer and magnetometer data and build a prototype home security system that can detect door openings and notify the homeowner via email, SMS and phone calls upon break-in detection. To further augment our security system, we explore using the smartphone’s built-in microphone to detect door and window openings across multiple doors and windows simultaneously. Experiments in a residential home show that the accelerometer- based detection can detect door open events with an accuracy higher than 98%, and magnetometer-based detection has 100% accuracy. By using the magnetometer method to automate the training phase of a neural network, we find that sound-based detection of door openings has an accuracy of 90% across multiple doors

Fully Integrated Biochip Platforms for Advanced Healthcare

Recent advances in microelectronics and biosensors are enabling developments of innovative biochips for advanced healthcare by providing fully integrated platforms for continuous monitoring of a large set of human disease biomarkers. Continuous monitoring of several human metabolites can be addressed by using fully integrated and minimally invasive devices located in the sub-cutis, typically in the peritoneal region. This extends the techniques of continuous monitoring of glucose currently being pursued with diabetic patients. However, several issues have to be considered in order to succeed in developing fully integrated and minimally invasive implantable devices. These innovative devices require a high-degree of integration, minimal invasive surgery, long-term biocompatibility, security and privacy in data transmission, high reliability, high reproducibility, high specificity, low detection limit and high sensitivity. Recent advances in the field have already proposed possible solutions for several of these issues. The aim of the present paper is to present a broad spectrum of recent results and to propose future directions of development in order to obtain fully implantable systems for the continuous monitoring of the human metabolism in advanced healthcare applications

Is the responsibilization of the cyber security risk reasonable and judicious?

Cyber criminals appear to be plying their trade without much hindrance. Home computer users are particularly vulnerable to attack by an increasingly sophisticated and globally dispersed hacker group. The smartphone era has exacerbated the situation, offering hackers even more attack surfaces to exploit. It might not be entirely coincidental that cyber crime has mushroomed in parallel with governments pursuing a neoliberalist agenda. This agenda has a strong drive towards individualizing risk i.e. advising citizens how to take care of themselves, and then leaving them to face the consequences if they choose not to follow the advice. In effect, citizens are “responsibilized .” Whereas responsibilization is effective for some risks, the responsibilization of cyber security is, we believe, contributing to the global success of cyber attacks. There is, consequently, a case to be made for governments taking a more active role than the mere provision of advice, which is the case in many countries. We conclude with a concrete proposal for a risk regulation regime that would more effectively mitigate and ameliorate cyber risk
