Apparatus for and method of multi-factor authentication among collaborating communication devices

摘要

Multi-factor authentication is enabled across a plurality of communication devices. A user performs authentication by using a first authentication factor on a first of the communication devices, and by using a second authentication factor on a second of the communication devices. A collaboration credential is shared among the devices to enable the devices to collaborate with each other. Both of the authentication factors are bound together. A multi-factor identification token is issued to each device, to support multi-factor authentication for the user across the devices.

1. An apparatus for multi-factor authentication among a plurality of communication devices, comprising:
a server having a processor that is configured to: authenticate a user who uses a first authentication factor on a first of the communication devices, and who uses a second authentication factor on a second of the communication devices; transmit a collaboration credential and a single factor identity token to the first communication device to enable the communication devices to collaborate with each other, wherein the collaboration credential gives permission for the first and second devices to share services among devices, receive the collaboration credential from the second of the communication devices along with a second authentication factor; and bind both of the authentication factors, and issue a multi-factor identification token to each of the communication devices, to support multi-factor authentication for the user across the plurality of communication devices to request access to a service.
