Abstract

A system and method provide efficient, secure, and highly reliable authentication for transaction processing and/or access control applications. A personal digital key (PDK) is programmed using a trusted programming device to initialize and/or register the PDK for use. In one embodiment, the initialization and registration processes are administered by a specialized trusted Notary to ensure the processes follow defined security procedures. In a biometric initialization, the programming device acquires a biometric input from a user and writes the biometric data to a tamperproof memory in the PDK. In registration, the Programmer communicates to one or more remote registries to create or update entries associated with the user PDK. Once initialized and registered, the PDK can be used for various levels of secure authentication processes.

Claims (33)

1 . A method comprising:

acquiring, by a portable user device, an image of a biometric characteristic of a user, including at least one of, an iris scan, a retinal scan, a finger print scan, and a palm associated with the user;

automatically computing a mathematical one-way hash of the biometric characteristic;

comparing, by the portable user device, the mathematical one-way hash of the biometric characteristic of the user with a biometric profile stored in the portable user device;

responsive to the comparing, determining that the mathematical one-way hash of biometric characteristic matches with the biometric profile;

responsive to determining that the mathematical one-way hash of the biometric characteristic of the user matches with the biometric profile, automatically detecting that the portable user device is within a proximity zone of a reader device, and establishing a wireless communication channel between the portable user device and the reader device; and

transmitting transaction information for a transaction executable on the portable user device, to the reader device via the wireless communication channel, the reader device requesting a validation of the transaction information from a trusted system and performing the transaction using the transaction information responsive to receiving the validation of the transaction information from the trusted system.

2 . The method of claim 1 , wherein the reader device is associated with a point-of-sale terminal and the transaction relates to a purchase.

3 . The method of claim 1 , wherein the reader device is associated with an automated teller machine and the transaction relates to a withdrawal from the automated teller machine, wherein the withdrawal is initiated in one configuration from a group including by a holder of the portable user device establishing contact with the reader device, by the holder of the portable user device taking an action to express an intent to purchase, and by detecting presence of the holder of the portable user device within range of the reader device.

4 . The method of claim 1 , wherein the biometric profile is encoded and transmitted to the reader device.

5 . The method of claim 1 , wherein the biometric profile is encoded and transmitted to the reader device with at least one of, an encoding key, an algorithm, and an encoding key and an algorithm.

6 . The method of claim 1 , wherein the portable user device includes a biometric scanner to acquire a biometric input of the user.

7 . The method of claim 6 , wherein the biometric scanner acquires at least one of, an iris scan, a retinal scan, a finger print scan, and a palm associated with the user.

8 . The method of claim 1 , wherein the portable user device is coupled to a portable notary device.

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 , wherein the trusted system is a third-party system independent of the portable user device and the reader device.

11 . The method of claim 1 , wherein the transaction information is associated with a default payment option.

12 . The method of claim 1 , wherein the transaction information is associated with a payment option selected by the user at a time of the transaction from a plurality of payment options.

13 . The method of claim 1 , wherein the transaction information is associated with an identification code uniquely identifying the portable user device.

14 . 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:

acquiring, by a portable user device, an image of a biometric characteristic of a user, including at least one of, an iris scan, a retinal scan, a finger print scan, and a palm associated with the user;

automatically computing a mathematical one-way hash of the biometric characteristic of the user;

comparing, by the portable user device, the mathematical one-way hash of the biometric characteristic of the user with a biometric profile stored in the portable user device;

responsive to the comparing, determining that the mathematical one-way hash of the biometric characteristic of the user matches with the biometric profile;

responsive to determining that the mathematical one-way hash of the biometric characteristic of the user matches with the biometric profile and automatically detecting that the portable user device is within a proximity zone of a reader device, establishing a wireless communication channel between the portable user device and the reader device; and

transmitting transaction information for a transaction from the portable user device to the reader device via the wireless communication channel, the reader device requesting a validation of the transaction information from a trusted system and performing the transaction using the transaction information responsive to receiving the validation of the transaction information from the trusted system.

15 . The system of claim 14 , wherein the reader device is associated with a point-of-sale terminal and the transaction includes a purchase.

16 . The system of claim 14 , wherein the reader device is associated with an automated teller machine and the transaction relates to a withdrawal from the automated teller machine, wherein the withdrawal is initiated in at least one configuration from a group including by a holder of the portable user device establishing contact with the reader device, by the holder of the portable user device taking an action to express an intent to purchase, and by detecting presence of the holder of the portable user device within range of the reader device.

17 . The system of claim 14 , wherein the portable user device includes at least one of a wearable device or a cellular phone.

18 . The system of claim 14 , wherein the portable user device includes a biometric scanner to acquire a biometric input of the user.

19 . The system of claim 18 , wherein the biometric scanner includes a camera.

20 . The system of claim 18 , wherein acquiring at least one of the iris scan, the retinal scan, the finger print scan, and the palm associated with the user of the user is performed by the biometric scanner.
