Authentication for Identity Fraud Prevention


Let's define "identity fraud" more precisely to include:  


This definition encompasses a range of identity-related crimes that can harm the victim in a number of ways.  This harm includes privacy breaches when sensitive financial and medical information is obtained by an unauthrized person, money stolen from the victim's bank account, charges billed to the victim that were incurred by the thief, erroneous and detrimental information appearing on the victim's credit report, and erroneous medical information appearing in the victim's medical record.  

Better authentication can help to prevent these crimes by:



Note that the kinds of authentication required to prevent these different forms of identity fraud do not necessarily involve authentication of a person's identity.  In fact, authentication of a claimed identity is really needed only when a new account (or relationship) is being established, and it is important to know the true identity of the person opening the account.  Once the account is established, authentication for subsequent access to the account requires only verification that the person seeking access is the same person who initially enrolled, or is otherwise authorized to do so.  By analogy, consider the ATM card.  Possession of the card, and knowledge of the associated PIN, doesn't serve to authenticate the holder's identity.  It only authenticates the holder's authority to access the account and withdraw money.  

While there are several technologies that can be used to provide stronger authentication to consumers to prevent these forms of identity fraud, we will focus on an emerging paradigm called "Information Cards", which are a kind of electronic version of the familiar physical credit cards and identity cards that people carry around.
