Abstract
An authentication device that is configured to receive an authentication request that includes a device identifier from a user device. The authentication device is further configured to identify a first device that is associated with the device identifier and to send a device fingerprint request to the first device. The authentication device is further configured to receive a first device fingerprint for the first device. The first device fingerprint is uniquely associated with the first device and includes a unique bit string that is generated based on a configuration of the first device. The authentication device is further configured to identify a second device fingerprint that is associated with the first device from among a plurality of device fingerprints stored in a memory, to compare the first device fingerprint to the second device fingerprint, and to send an authentication response to the user device based on the comparison.
