Abstract: An advanced identity verification system, method, and computer program product are provided that enable a user to create and individualize a repository of identifying data, and then incorporate that repository into processes that require reliable identification of an individual. Real-world acquaintances of the user can be queried to determine the accuracy of identifying data in the repository. As more and more acquaintances respond concerning a particular item of identifying data, a numeric accuracy index may be provided that permits an inquiring party to determine whether the identifying data may be trusted.
