Finding a Needle in a Haystack
Current aviation security systems identify behavioral indicators of deception to assess risks to flights, but they lack a strong psychological basis or empirical validation. We present a new method that tests the veracity of passenger accounts. In an in vivo double-blind randomized-control trial conducted in international airports, security agents detected 66% of deceptive passengers using the ...
متن کاملPicviz: Finding a Needle in a Haystack
When considering log files for security, usual applications available today either look for patterns using signature databases or use a behavioral approach. In both cases, information can be missed. The problem becomes bigger with systems receiving a massive amount of logs. Parallel coordinates is an answer to display an infinity of events in multiple dimensions. As security data are multivaria...
متن کاملFinding a Needle in a Haystack: An Image Processing Approach
Image segmentation (also known as object/edge detection) is the process of dividing an image into its constituent parts using information about the boundaries between objects, edges within objects, variations in intensity, et cetera. Often, the human eye can easily recognize salient information from an image; however, background variations in intensity, noise and other degradations, and other h...
متن کاملDark Matter Detection: Finding a Halo in a Haystack
The predictive modeling competition platform Kaggle TM recently posed the Observing Dark Worlds prize, challenging researchers to design a supervised learning algorthim that predicts the position of dark matter halos in images of the night sky. Although dark matter neither emits nor absorbs light, its mass bends the path of a light beam passing near it. Regions with high densities of dark matte...
متن کاملLocality-Sensitive Hashing: Finding a Needle in a Haystack
I. SCOPE One of the more surprising changes in computing during the last few years is the wealth of data that is now available at our fingertips. We can easily carry in our pockets thousands of songs, hundreds of thousands of images, and hundreds of hours of video. But even with the rapid growth of computer performance, we don’t have the processing power to search this amount of data by brute f...
