US Patent 9001977 Telephone-based user authentication

This disclosure is directed to, in part, providing information about a user to a requesting party where the information is provided by an identity provider that has a preexisting relationship with the user. The user may request the identity provider to provide the information to the relying party using an interactive voice response (IVR) system. After the relying party requests the user's account information, the user may be redirected, at least momentarily, to an IVR system provided by the identity provider. The IVR system may authenticate the user. Once authenticated, the identity provider may provide the user information to the relying party. By authenticating the user, the identity provider may provide the user information to the relying party without compromising user credentials or other private or sensitive information of the user.
