Abstract
Identity theft is causing million losses not only to companies but also to individuals. To date, researchers have investigated and engineered biometric systems to counter the problem. One such system is based on biometric sensors that could dramatically curtail identify theft. The system primarily uses fingerprint sensors although other biometric technologies could be employed. If widely implemented, these and other related systems could put thousands of identity thieves out of business and spare countless individuals the nightmare of trying to get their good names and credit back. Although the technology to implement these systems already exists, ongoing research efforts aimed at improving the performance of biometric systems in general and sensors in particular will make them even more reliable, robust, and convenient.
