Abstract

The present invention enables automatic authentication of a personal digital key based upon proximity of the key which is associated with a person. The system enables linking of the personal digital key to an account based upon the automatic authentication. The personal digital key includes encrypted digital data unique thereto, which enables automatic authentication based upon proximity thereof to a receiver and the account linking system. The system further includes an account linking system based upon automatic authentication of the personal digital key. The account linking system comprises a receiver/decoder circuit, which is able to automatically authenticate the personal digital key, whereby the personal digital key is able to be linked to and associated with an account.

First claim

I claim:

1. A system comprising:
a first personal digital key associated with an owner, the personal digital key capturing, at the first personal digital key, biometric information from a first person and authenticating, at the first personal digital key, the first person as the owner of the first personal digital key based at least in part on the captured biometric information, the first personal digital key including an encrypted digital key identifier unique to the first personal digital key for enabling automatic authentication of the first personal digital key and, upon the first personal digital key authenticating the first person as the owner based on the captured biometric information, transmitting that same encrypted digital key identifier without the biometric information; and
an account linking system that performs automatic authentication of the first personal digital key, the account linking system including a receiver or decoder circuit integrated into a first device, the receiver or decoder circuit having a range defining proximity and automatically authenticating the first personal digital key based on the encrypted digital key identifier received responsive to the first personal digital key being in proximity to the receiver or decoder circuit and responsive to the first personal digital key authenticating the first person as the owner, the first personal digital key and the receiver or decoder circuit automatically authenticating each other when in proximity to one, the receiver or decoder circuit detecting an item that is included in a plurality of items that are associated with the first personal digital key in a linked account responsive to authentication, the linked account, tracking the plurality of items associated with the first personal digital key, stored in a central database and the linked account being:
(a) decrypted responsive to the first personal digital key being located in a proximity to the receiver or decoder circuit and the first personal digital key being authenticated by the receiver or decoder circuit, the first personal digital key authenticated by the receiver or decoder circuit subsequent to the first personal digital key authenticating the first person as the owner of the first personal digital key based at least in part on the captured biometric information, and
(b) encrypted responsive to the first personal digital key being located out of the proximity to the receiver or decoder circuit,

the account linking system accumulating data associated with a plurality of personal digital keys associated with different persons in an area including content received at a second device in use by an owner of a second personal digital key, the plurality of personal digital keys including the first personal digital key and the second personal digital key, determining devices associated with the area including the first device and the second device, determining to provide content similar to the content received at the second device in use by the owner of the second personal digital key to the first device based on satisfaction of a predefined threshold associated with the accumulated data associated with the plurality of personal digital keys in the area and including the content received at the second device in use by an owner of a second personal digital key as well as the linked account, the receiver or decoder circuit including a non-user-modifiable unique identifier associated with the receiver or decoder circuit and different from the encrypted digital key identifier received from the first personal digital key, the non-user-modifiable unique identifier associated with the receiver or decoder circuit used by a server to encrypt the determined content, the determined content received at the first device and sent from the server.

2. A system as in claim 1 , wherein the plurality of items includes one or more a secured file, a drive, a door, a computer and a gaming machine.

3. A system as in claim 1 , wherein the first personal digital key transmits the unique encrypted digital key identifier to the receiver or decoder circuit through a secure wireless link.

4. A system as in claim 1 , wherein the unique encrypted digital key identifier is a non-user-modifiable and non-biometric, and set during manufacture of the first personal digital key.

5. A system as in claim 1 , wherein the receiver or decoder circuit is able to detect, authenticate, and securely communicate with the first personal digital key.

6. A system as in claim 1 , wherein the linked account includes data therein, and the receiver or decoder circuit is able to access the data in the linked account based upon automatic authentication of the first personal digital key.

7. A system as in claim 1 , wherein the range defining proximity to the receiver or decoder circuit to enable account linking is dynamically adjustable after manufacture of the receiver decoder circuit.

8. A system as in claim 1 , wherein the system is able to provide a customized service for the linked account.

9. A system as in claim 1 , wherein the first personal digital key and receiver or decoder circuit include embedded challenge-response logic and cryptographic algorithms, for enabling authentication of the first personal digital key and the receiver or decoder circuit as original, not copied, authorized devices.

10. A system as in claim 1 , wherein the first device is a gaming machine and games are able to be downloaded to the gaming machine, the gaming machine including the receiver or decoder circuit, the linked account tracking preferences through the system regarding games, and, based upon the preferences, and using the receiver or decoder circuit non-user-modifiable and non-biometric unique identifier, the system is able to encrypt and download such games to the gaming machine.

11. A system as in claim 1 , wherein the receiver or decoder circuit is able to detect, authenticate, and securely communicate with multiple personal digital keys in parallel.

12. A system as in claim 1 , wherein the system includes a network, the network includes one or more servers, which includes the server, and one or more other devices, which includes the first device, wherein, each of the one or more other devices includes the receiver or decoder circuit, and wherein transaction data is able to flow across the network between the one or more servers and the one or more other devices, and the receiver or decoder circuits in the one or more other devices are able to encrypt and decrypt the transaction data so as to protect the transaction data, wherein the transaction data is encrypted between the server and the first device using a first receiver or decoder circuit's non-user-modifiable and non-biometric unique identifier, the first receiver or decoder circuit in the first device.

13. A system as in claim 8 , wherein the customized service provided for the linked account is for a casino property.

14. A system as in claim 8 , where the customized service provided for the linked account is for a hotel property.

15. A system as in claim 10 , wherein the server is a game server and the content includes a game, wherein the system further includes the game server which includes games which the game server is able to encrypt, and wherein the receiver or decoder circuit in the gaming machine is able to accept games from the game server which have been encrypted with the receiver or decoder circuit's unique identifier as the encryption key, and wherein the receiver or decoder circuit is able to decrypt such games for play on the gaming machine.

16. A system as in claim 12
