Abstract: A method for verifying a consumer's identity in connection with a consumer/merchant transaction, including receiving a user-identifier from a user, receiving a unique device identifier from an electronic device associated with the user, associating the user-identifier and the unique device identifier of the user to a user account residing on a secured transaction server (“STS), the STS not operated by the merchant and including an identity verification agent. The method further includes receiving a consumer identity verification request at the STS, receiving a unique device identifier associated with an electronic device of the consumer at the STS, comparing, through the identity verification agent, the user's unique device identifier and the consumer's unique device identifier to determine at least one of a positive or negative user-identity verification, and then communicating to the merchant the at least one of the positive or negative user-identity verification.
