Authentication of mobile device for secure transaction

Abstract:

There are provided systems and methods for authenticating a mobile device for use in a secure transaction. A user having a master device authenticated for use in a secure transaction system, such as an electronic payment system, identifies a secondary device to be enabled for use in processing a secure transaction. The secondary device connects to a companion device and shares information associated with the secondary device and companion device with a transaction processing server, which returns authentication information associated with both devices. When the user initiates a secure transaction, the secondary device identifies whether the third device is in proximity. The secure transaction is processed only if the second and third devices are in communication and authenticated during the transaction. If the secondary device is lost or stolen, the device may be disabled until reauthenticated through the master device.
