Multimodal proximity detection
First Claim
1. A method to implement multimodal proximity detection in a first electronic device, comprising:
- initiating an environmental sampling routine in the first electronic device by;
activating an environmental sensor;
collecting at least one sample of environmental data;
extracting at least one feature set of the environmental data;
generating a first obscured feature from the feature set extracted from the first electronic device;
transmitting the first obscured feature set from the first electronic device to a proximity server; and
receiving, in the first electronic device, a signal indicating whether the first electronic device is proximate to a second electronic device;
receiving, in the first electronic device, an identifier associated with the second electronic device if the device was proximate; and
,establishing at least one context parameter based on the identifier when the device is proximate.

Abstract
Systems and methods for proximity detection between electronic devices are disclosed. One or more electronic devices transmit signals to a proximity server, which determines whether the first electronic device may be proximate the second electronic device. The proximity server transmits a signal to the first electronic device and the second device, and in response to the signal, the first and second electronic devices activate an environmental sensor, collect at least one sample of environmental data, extract at least one feature set of the environmental data, generate a first obscured feature from the feature set, transmit the first and second obscured feature sets to the proximity server. The proximity server uses the first obscured feature set and the second obscured feature set to determine whether the first electronic device and the second electronic device are proximate.
