Abstract: Techniques for authenticating the identity and validating the profile of an individual (“a presenter”) who presents him or herself to another party (“an acceptor”) as having a certain identity and having certain corresponding profile data are described. The invention can be advantageously used in Internet transactions where such authentication and validation is difficult to perform. The techniques of the present invention allow the trusted party to give a definitive answer regarding the authentication of identity and validity of profile data. Other services such as profile data provisioning and profile data updating can also be performed.

Abstract: A payment authentication service authenticates the identity of a payer during online transactions. The authentication service allows a card issuer to verify a cardholder's identity using a variety of authentication methods, such as the use of passwords. Also, the only system participant requiring a certificate is the issuing financial institution. Authenticating the identity of a cardholder during an online transaction involves querying an access control server to determine if a cardholder is enrolled in the payment authentication service, requesting a password from the cardholder, verifying the password, and notifying a merchant whether the cardholder's authenticity has been verified. A chip card and the authentication service independently generate cryptograms to match in order for the service to verify that the correct chip card is being used by the cardholder.

Abstract: Authenticating the identity and validating the profile of an individual who presents himself to another party as having a certain identity and corresponding profile data occurs during an Internet transaction. A trusted party gives a definitive answer regarding the authentication of identity and validity of profile data. The trusted party can be a financial institution that has an established relationship with the individual. For example, the financial institution can be a bank that issues a debit or credit card to the individual. The trusted party can also provide the profile data of the individual to the other party, rather than have the individual provide such data. The trusted party can also update the individual's profile data held by the other party when such data is no longer current.
