“This is a solution that IT security professionals need to be aware of as it can significantly improve the integrity of their organization’s end-point computing infrastructure,” says Michael Kelly, President of Viion Systems, who with Chief Technology Officer David McMordie, conceived the concept when they realized the state-of-the-art for securing computer sessions relied on an exceedingly low-tech ploy: Microsoft’s Windows inactivity timer.

Although other solutions were available at the time, none addressed the full spectrum of computer security issues. “We examined many potentially useful sensor technologies [including infrared ranging and ultrasonic], Kelly said, “and concluded that computer vision would provide two critical components that were missing in systems based on other technologies: the capacity to recognize and differentiate individuals and the faculty to track them over a satisfactory range-of-motion.”
