Abstract

Methods and systems for performing electronic commerce using mutating identifiers. One method can include encrypting buyer transaction data with a first mutating identifier, transmitting the buyer transaction data to an authenticator device, decrypting the buyer transaction data, generating a payment request, encrypting the payment request with a third mutating identifier, and transmitting the payment request to a payment authenticator device.
