Abstract
The search results of a first iteration of a biometric search are used to form a probe for subsequent iterations searches in a biometric database. his enables the search methodology to “drill down” into the database to find matching biometric templates. In addition, the results of a search using a template of first biometric type are used to limit the search applied using a template of a second biometric type to improve the effectiveness of a one to many search for matching data in a biometric database. These search methods are used in various combinations with different types of biometric templates and demographic information of an individual who is subject of the one to many search.
