Abstract

A system and method provide efficient, secure, and highly reliable authentication for transaction processing and/or access control applications. A Personal Digital Key stores one or more profiles (e.g., a biometric profile) in a tamper-proof memory that is acquired in a secure trusted process. Biometric profiles comprise a representation of physical or behavioral characteristics that are uniquely associated with an individual that owns and carries the PDK. The PDK wirelessly transmits the biometric profile over a secure wireless transaction to a Reader for use in a biometric authentication process. The Reader compares the received biometric profile to a biometric input acquired at the point of transaction in order to determine if the transaction should be authorized.

Claims (41)

1 . A method comprising:

determining a request for a transaction having a transaction amount;

determining that the transaction amount associated with the transaction is under a threshold;

detecting that a portable user device is within a proximity zone of a reader device; and

establishing a wireless communication channel between the reader device and the portable user device within the proximity zone of the reader device and transmitting the request for the transaction including the transaction amount and device identification information uniquely identifying the portable user device from the portable user device to the reader device via the wireless communication channel without an authentication of a user associated with the portable user device, the device identification information stored in a read-only format in a secured memory of the portable user device and unchangeable subsequent to a manufacture of the portable user device, the reader device locally authenticating that the portable user device is valid using the device identification information without any remote lookup, the reader device automatically performing the transaction responsive to detecting that the portable user device is within the proximity zone of the reader device, determining that the transaction amount associated with the transaction is under the threshold, and locally authenticating the portable user device is valid, the reader device synchronized with a trusted third-party system to periodically retrieve updated list of valid devices and their registered uniquely identifying device identification information from the trusted third-party system at regular time intervals for performing local authentication of portable user devices without any remote lookup.

2 . The method of claim 1 , further comprising:

responsive to determining that the transaction amount associated with the transaction is not under the threshold, receiving a request for performing a biometric profile authentication;

determining that the biometric profile authentication is successful; and

responsive to determining that the biometric profile authentication is successful and detecting that the portable user device is within the proximity zone of the reader device, transmitting the request for the transaction having the transaction amount and the device identification information uniquely identifying the portable user device from the portable user device to the reader device via the wireless communication channel.

3 . The method of claim 2 , wherein the biometric profile authentication includes at least one of a fingerprint scan authentication, a facial scan authentication, a voice analysis authentication, an iris scan authentication or a retinal scan authentication.

4 . The method of claim 2 , wherein determining that the biometric profile authentication is successful comprises:

acquiring, by the portable user device, a facial image of the user;

comparing, by the portable user device, the facial image of the user and a biometric profile stored in the portable user device; and

responsive to the comparing, determining that the facial image of the user matches the biometric profile.

5 . The method of claim 1 , further comprising presenting a representation of a default payment option associated with the transaction to a user and allowing the user to select another payment option for the transaction from a plurality of payment options.

6 . The method of claim 5 , wherein the plurality of payment options are stored by the portable user device and each payment option is associated with a funding source to be used to complete the transaction.

7 . The method of claim 1 , wherein the reader device is configured to request a validation of the transaction from the trusted third-party system and automatically perform the transaction responsive to receiving the validation of the transaction from the trusted third-party system.

8 . The method of claim 1 , wherein the reader device is associated with a point of sale terminal and the transaction includes a purchase.

9 . The method of claim 1 , wherein the portable user device includes at least one of a wearable device or a cellular phone.

10 . The method of claim 1 , further comprising storing data in association with the transaction in the portable user device responsive to the reader device automatically performing the transaction.

11 . The method of claim 10 , wherein the data in association with the transaction includes one or more of a name of a merchant, a purchase amount, and a payment option used for the transaction.

12 . A system comprising:

a computing device and a memory including instructions that, when executed by the computing device, cause the system to perform operations including:

determining a request for a transaction having a transaction amount;

determining that the transaction amount associated with the transaction is under a threshold;

detecting that a portable user device is within a proximity zone of a reader device; and

establishing a wireless communication channel between the reader device and the portable user device within the proximity zone of the reader device and transmitting the request for the transaction including the transaction amount and device identification information uniquely identifying the portable user device from the portable user device to the reader device via the wireless communication channel without an authentication of a user associated with the portable user device, the device identification information stored in a read-only format in a secured memory of the portable user device and unchangeable subsequent to a manufacture of the portable user device, the reader device locally authenticating that the portable user device is valid using the device identification information without any remote lookup, the reader device automatically performing the transaction responsive to detecting that the portable user device is within the proximity zone of the reader device, determining that the transaction amount associated with the transaction is under the threshold, and locally authenticating the portable user device is valid, the reader device synchronized with a trusted third-party system to periodically retrieve updated list of valid devices and their registered uniquely identifying device identification information at regular time intervals from the trusted third-party system for performing local authentication of portable user devices without any remote lookup.

13 . The system of claim 12 , further comprising:

responsive to determining that the transaction amount associated with the transaction is not under the threshold, receiving a request for performing a biometric profile authentication;

determining that the biometric profile authentication is successful; and

responsive to determining that the biometric profile authentication is successful and detecting that the portable user device is within the proximity zone of the reader device, transmitting the request for the transaction having the transaction amount and the device identification information uniquely identifying the portable user device from the portable user device to the reader device via the wireless communication channel.

14 . The system of claim 13 , wherein the biometric profile authentication includes at least one of a fingerprint scan authentication, a facial scan authentication, a voice analysis authentication, an iris scan authentication or a retinal scan authentication.

15 . The system of claim 13 , wherein determining that the biometric profile authentication is successful comprises:

acquiring, by the portable user device, a facial image of the user;

comparing, by the portable user device, the facial image of the user and a biometric profile stored in the portable user device; and

responsive to the comparing, determining that the facial image of the user matches the biometric profile.

16 . The system of claim 12 , further comprising presenting a representation of a default payment option associated with the transaction to a user and allowing the user to select another payment option for the transaction from a plurality of payment options.

17 . The system of claim 16 , wherein the plurality of payment options are stored by the portable user device and each payment option is associated with a funding source to be used to complete the transaction.

18 . The system of claim 12 , wherein the reader device is configured to request a validation of the transaction from the trusted third-party system and automatically perform the transaction responsive to receiving the validation of the transaction from the trusted third-party system.

19 . The system of claim 12 , wherein the reader device is associated with a point of sale terminal and the transaction includes a purchase.

20 . The system of claim 12 , wherein the portable user device includes at least one of a wearable device or a cellular phone.
