Uniquely identifying an individual based on biometric information can currently be performed by using fingerprints, facial images and eye scans. These techniques frequently require the cooperation or at a minimum the acknowledgement from an individual that information is being gathered from them. An urgent need arises for non-cooperative surreptitious biometric collection tools. Such a biometric that can be collected from a distance (space and time) is an individual s scent. For individual identification, one needs to look at the volatile organic compounds (VOCs) in the scent that reflect the individual s gene expression. The Phase I effort established an initial list VOCs that are known to be genetically regulated, established concentration levels to sensed, formulated an algorithm to uniquely identify an individual and demonstrated feasibility that a gas chromatograph coupled with a differential mobility spectrometer (GC/DMS) can provide the needed selectivity and sensitivity in a small, robust and relatively inexpensive package. The Phase 2 effort will produce algorithm software to uniquely identify an individual based on their genetically controlled VOCs as measured on a GC/DMS tool. We will design a study to verify and validate these algorithms. We will construct two GC/DMS prototypes demonstrating improved state-of-the-art of IBIS technology.
