Towards Trustworthy Participatory Sensing

Abstract Grassroots Participatory Sensing empowers people to collect and share sensor data using mobile devices across many applications, spanning intelligent transportation, air quality monitoring and social networking. In this paper, we argue that the very openness of such a system makes it vulnerable to abuse by malicious users who may poison the information, collude to [...]

T-Ray Sensing and Imaging

Abstract Terahertz-ray (T-ray) wavelengths are long enough to pass through dry, nonpolar objects opaque at visible wavelengths, but short enough to be manipulated by optical components to form an image. Sensing in this band potentially provides advantages in a number of areas of interest to security and defense such as screening of personnel for hidden [...]

Critical Elements of Biological Sensor Technology for Deployment in an Environmental Network System

Abstract A key factor affected for the ability to protect against biological and chemical threats is the deployment of an automated sensor monitoring system for use in government and commercial applications. Currently available biosensors have several shortcomings that must be overcome: 1) they are slow to recognize the presence of a pathogen; 2) they are [...]
