Abstract:
1. A method for authenticating the purported identity of an authentication subject represented by a plurality of identification items, each identification item being of an item type verifiable via one or more of a plurality of data sources, the method comprising the steps of: for each identification item, identifying a pair-wise link to each other identification item using known information about the corresponding item types verifiable via each data source, wherein each pair-wise link associates the linked identification items as potentially representing the purported identity; querying one or more of the plurality of data sources to obtain an indication of confidence that the identification items of each pair-wise link represent the purported identity; determining an overall confidence indication for the plurality of identification items based on the indications of confidence corresponding to the individual pair-wise links; and evaluating the overall confidence indication against an authentication criterion.
