    Microbilt ID Authenticate
    ID Authenticate offers businesses the ability to confirm that an individual participating in a transaction is the same person that owns the Personal Identifying Information being submitted. This product works by presenting the individuals with an array of out-of-wallet, knowledge-based questions that should be known to the true owner of the person’s identity. ID Authenticate uses an individual’s SSN, name and address to derive and present a series of questions about the person’s address history, asset ownership and other information that can only be answered by the applicant that owns the identity presented. Once responses are given to the authentication questions, ID Authenticate delivers an authentication score to indicate whether the respondent passed or failed the quiz, thus allowing a business to confirm if the subject with whom they are transacting is the true owner of the identity submitted.
