Augmenting Wi-Fi localization with auxiliary sensor information
First Claim
1. A method comprising:
- at a controller including one or more processors and non-transitory memory;
detecting a first address associated with a first device at a first time, wherein the first device is characterized by first characterization information;
tracking the first device based on the first address;
ceasing to detect the first address and detecting a second address associated with a second device at a second time, wherein ceasing to detect the first address includes detecting a potential randomization event and ceasing to track the first device, and wherein the second device is characterized by second characterization information; and
associating the second address with the first address to continue tracking the first device in response to determining that that the second characterization information associated with the second device matches the first characterization information associated with the first device within a threshold tolerance.

Abstract
In one implementation, a method of maintaining continuous identity for mobile devices includes: obtaining a first address for a first device; and obtaining, from one or more auxiliary sensors, auxiliary sensor information related to the first device. The method also includes determining whether the auxiliary sensor information matches information associated with a second address, where the second address was previously associated with the first device. The method further includes linking the first address with the second address for the first device, in order to continue tracking the first device when the second address is no longer detected, in response to determining that the auxiliary sensor information matches information associated with the second address.

11. A non-transitory memory storing one or more programs, which, when executed by one or more processors of a controller, cause the controller to:
-
detect a first address associated with a first device at a first time, wherein the first device is characterized by first characterization information; track the first device based on the first address; cease to detect the first address and detect a second address associated with a second device at a second time, wherein ceasing to detect the first address includes detecting a potential randomization event and ceasing to track the first device, and wherein the second device is characterized by second characterization information; and associate the second address with the first address to continue tracking the first device in response to determining that that the second characterization information associated with the second device matches the first characterization information associated with the first device within a threshold tolerance. - View Dependent Claims (12, 13, 14, 15)

16. A controller comprising:
-
one or more processors; a non-transitory memory; and one or more programs, the one or more programs are stored in the non-transitory memory and configured to be executed by the one or more processors, and the one or more programs include instructions for causing the controller to; detect a first address associated with a first device at a first time, wherein the first device is characterized by first characterization information; track the first device based on the first address; cease to detect the first address and detect a second address associated with a second device at a second time, wherein ceasing to detect the first address includes detecting a potential randomization event and ceasing to track the first device, and wherein the second device is characterized by second characterization information; and associate the second address with the first address to continue tracking the first device in response to determining that that the second characterization information associated with the second device matches the first characterization information associated with the first device within a threshold tolerance. - View Dependent Claims (17, 18, 19)
