Abstract

A system includes a data processing system comprising one or more processors. The processor(s) are configured to identify one or more linking factors to determine that a first computing device is linked to a second computing device, with a certain probability, where the second computing device is proximate to the first computing device. The processor(s) are further configured to link the first computing device with the second computing device based on the determining, receive a request for content from the first computing device, provide the content to the second computing device, and generate a data structure to indicate a link between the first computing device and the second computing device.

Claims (40)

1. A system comprising:

a data processing system comprising one or more processors, the one or more processors configured to:

identify one or more linking factors to determine that a first computing device is linked to a second computing device, with a certain probability, wherein the second computing device is proximate to the first computing device;

link the first computing device with the second computing device based on the determining;

receive a request for content from the first computing device;

provide the content to the second computing device; and

generate a data structure to indicate a link between the first computing device and the second computing device.

2. The system of claim 1 , wherein the one or more linking factors include input activity at one of the first computing device and the second computing device during a first time period.

3. The system of claim 1 , wherein the one or more linking factors include input activity at one of the first computing device and the second computing device during a first time period corresponding to a cessation of activity at the other of the first computing device and the second computing device during a second time period.

4. The system of claim 1 , wherein the one or more linking factors include activity at the first computing device and the second computing device via one or more IP addresses.

5. The system of claim 4 , wherein the one or more linking factors include activity at the first computing device via a first IP address during a first time period and activity at the second computing device via a second IP address during the first time period.

6. The system of claim 1 , wherein the one or more linking factors include a plurality of linking factors.

7. The system of claim 1 , wherein identifying the one or more linking factors includes determining a positive match probability and a negative match probability based on known links and known non-links.

8. The system of claim 7 , wherein the one or more processors are configured to set a default positive match probability and a default negative match probability equal to 0%.

9. The system of claim 7 , wherein the one or more processors are configured to:

link the first computing device with the second computing device based on the positive match probability, the negative match probability, and weights corresponding to the positive match probability and the negative match probability; and

determine the weights corresponding to the positive match probability and the negative match probability based on a machine learning model.

10. The system of claim 7 , wherein the one or more processors are configured to:

link the first computing device with the second computing device based on the positive match probability, the negative match probability, and weights corresponding to the positive match probability and the negative match probability; and

determine the weights corresponding to the positive match probability and the negative match probability based on a regression analysis.

11. A method for providing content, the method comprising:

identifying, by a data processing system, one or more linking factors to determine that a first computing device is linked to a second computing device, with a certain probability, wherein the second computing device is proximate to the first computing device;

linking, by the data processing system, the first computing device with the second computing device based on the determining;

receiving, by the data processing system, a request for content from the first computing device;

providing, by the data processing system, the content to the second computing device; and

generating, by the data processing system, a data structure to indicate a link between the first computing device and the second computing device.

12. The method of claim 11 , wherein the one or more linking factors include input activity at one of the first computing device and the second computing device during a first time period.

13. The method of claim 11 , wherein the one or more linking factors include input activity at one of the first computing device and the second computing device during a first time period corresponding to a cessation of activity at the other of the first computing device and the second computing device during a second time period.

14. The method of claim 11 , wherein the one or more linking factors include activity at the first computing device and the second computing device via one or more IP addresses.

15. The method of claim 14 , wherein the one or more linking factors include activity at the first computing device via a first IP address during a first time period and activity at the second computing device via a second IP address during the first time period.

16. The method of claim 11 , wherein the one or more linking factors include a plurality of linking factors.

17. The method of claim 11 , wherein identifying the one or more linking factors includes determining a positive match probability and a negative match probability based on known links and known non-links.

18. The method of claim 17 , further comprising:

setting, by the data processing system, a default positive match probability and a default negative match probability equal to 0%.

19. The method of claim 17 , wherein the linking includes:

linking the first computing device with the second computing device based on the positive match probability, the negative match probability, and weights corresponding to the positive match probability and the negative match probability; and

determining the weights corresponding to the positive match probability and the negative match probability based on a machine learning model.

20. The method of claim 17 , wherein the linking includes:

linking the first computing device with the second computing device based on the positive match probability, the negative match probability, and weights corresponding to the positive match probability and the negative match probability; and

determining the weights corresponding to the positive match probability and the negative match probability based on a regression analysis.
