Abstract

Systems, methods, devices, instructions, and other aspects are provided for unique device identification. In one aspect, a method is providing including receiving, at a server computer, transaction data associated with a client device, wherein the transaction data includes device configuration data, aggregating the device configuration data for the client device received within a threshold time period to generate a unique set of device configuration characteristics, receiving, at the server computer, transaction request data associated with the client device, verifying the client device using the unique set of device configuration characteristics, and facilitating a transaction associated with the transaction request data based on verification of the client device using the unique set of device configuration characteristics.

First claim

What is claimed is:

1. A computer-implemented method for device fingerprinting, the method comprising:
matching device configuration data associated with a plurality of devices including a client device, wherein the device configuration data includes data for the client device, and wherein matching includes using a time period to generate a unique set of device configuration characteristics associated with the time period;
training a learning system including a neural network to create one or more datasets that result in uniqueness for devices;
identifying, via the neural network, one or more device configuration characteristics that create a non-unique overlap between device configuration characteristics associated with one or more other devices of the plurality of devices;
reducing memory use within a server computer and reducing opportunities for spoofing by removing the one or more device configuration characteristics from the set of device configuration characteristics, wherein removing includes associating the device configuration characteristics with a deletion timer and generating a unique set of device configuration characteristics that are deleted when the deletion timer expires without additional device configuration characteristics being received by the client device;
receiving, at the server computer, transaction request data associated with the client device;
verifying the client device using the unique set of device configuration characteristics; and
facilitating a transaction associated with the transaction request data based on verification of the client device using the unique set of device configuration characteristics.

2. The computer-implemented method of claim 1 , wherein the unique set of device configuration characteristics includes canvas details for the client device associated with the time period.

3. The computer-implemented method of claim 1 , wherein the unique set of device configuration characteristics includes partner identifiers received from one or more third party servers associated with the client device.

4. The computer-implemented method of claim 1 , wherein the unique set of device configuration characteristics includes data from a validated uniform resource locator history tracked via cookies or via local storage at the client device accessible by the server computer.

5. The computer-implemented method of claim 1 , wherein the unique set of device configuration characteristics are accessed by the server computer using hypertext transform protocol-based post and get commands with the client device.

6. The computer-implemented method of claim 1 , further comprising:
storing the unique set of device configuration characteristics in a cross-domain identification database.

7. The computer-implemented method of claim 1 , wherein the unique set of device configuration characteristics are associated with a 48 hour deletion timer.

8. A device comprising:
memory; and
one or more processors coupled to the memory and configured for:
matching device configuration data associated with a plurality of devices including a client device, wherein the device configuration data includes data for the client device, and wherein matching includes using a time period to generate a unique set of device configuration characteristics associated with the time period;
training a learning system including a neural network to create one or more datasets that result in uniqueness for devices;
identifying, via the neural network, one or more device configuration characteristics that create a non-unique overlap between device configuration characteristics associated with one or more other devices of the plurality of devices;
reducing memory use within a server computer and reducing opportunities for spoofing by removing the one or more device configuration characteristics from the set of device configuration characteristics, wherein removing includes associating the device configuration characteristics with a deletion timer and generating a unique set of device configuration characteristics that are deleted when the deletion timer expires without additional device configuration characteristics being received by the client device;
receiving transaction request data associated with the client device;
verifying the client device using the unique set of device configuration characteristics; and
facilitating a transaction associated with the transaction request data based on verification of the client device using the unique set of device configuration characteristics.

9. The device of claim 8 , wherein the unique set of device configuration characteristics includes canvas details for the client device associated with the time period.

10. The device of claim 8 , wherein the unique set of device configuration characteristics includes partner identifiers received from one or more third party servers associated with the client device.

11. The device of claim 8 , wherein the unique set of device configuration characteristics includes data from a validated uniform resource locator history tracked via cookies or via local storage at the client device accessible by the server computer.

12. The device of claim 8 , wherein the unique set of device configuration characteristics are accessed by the server computer using hypertext transform protocol-based post and get commands with the client device.

13. The device of claim 8 , wherein the one or more processors are configured for operations further comprising:
storing the unique set of device configuration characteristics in a cross-domain identification database.

14. The device of claim 8 , wherein the unique set of device configuration characteristics are associated with a 48 hour deletion timer.

15. A non-transitory computer readable storage medium comprising instructions that, when executed by one or more processors of a device, cause the device to perform operations including:
matching device configuration data associated with a plurality of devices including a client device, wherein the device configuration data includes data for the client device, and wherein matching includes using with a time period to generate a unique set of device configuration characteristics associated with the time period;
training a learning system including a neural network to create one or more datasets that result in uniqueness for devices;
identifying, via the neural network, one or more device configuration characteristics that create a non-unique overlap between device configuration characteristics associated with one or more other devices of the plurality of devices;
reducing memory use within a server computer and reducing opportunities for spoofing by removing the one or more device configuration characteristics from the set of device configuration characteristics, wherein removing includes associating the device configuration characteristics with a deletion timer and generating a unique set of device configuration characteristics that are deleted when the deletion timer expires without additional device configuration characteristics being received by the client device;
receiving, at a server computer, transaction request data associated with the client device;
verifying the client device using the unique set of device configuration characteristics; and
facilitating a transaction associated with the transaction request data based on verification of the client device using the unique set of device configuration characteristics.

16. The non-transitory computer readable storage medium of claim 15 , wherein the unique set of device configuration
