Abstract

Techniques are provided to allow third party devices to be paired with enterprise devices by simply manipulating the display of a third party device. More specifically, the techniques presented herein change properties of displays and/or display-drivers so that third party devices radiate controlled information via electro-magnetic interference (EMI) that can be utilized for pairing. Consequently, the third party devices can be easily paired with enterprise devices in a simple and robust manner. This pairing allows information to be safely exchanged between a third-party device (e.g., smartphone) and an enterprise device in the same room without requiring user interaction or interaction or an installation of hardware in a third party device.

PAIRING THIRD PARTY DEVICES WITH ENTERPRISE DEVICES BY UTILIZING ELECTRO-MAGENTIC INTERFERENCE

ABSTRACT

    Techniques are provided to allow third party devices to be paired with enterprise devices by simply manipulating the display of a third party device. More specifically, the techniques presented herein change properties of displays and/or display-drivers so that third party devices radiate controlled information via electro-magnetic interference (EMI) that can be utilized for pairing. Consequently, the third party devices can be easily paired with enterprise devices in a simple and robust manner. This pairing allows information to be safely exchanged between a third-party device (e.g., smartphone) and an enterprise device in the same room without requiring user interaction or interaction or an installation of hardware in a third party device.

DETAILED DESCRIPTION

    As enterprises implement bring-your-own-device (BYOD) policies, there is a need to pair third party devices with enterprise devices. Pairing an enterprise device or product with a third party device (e.g., a smart phone) allows the enterprise to trust, with a large probability, that the third party device (e.g., an employee's device) is physically in the room and, thus, this device can be granted similar rights as a physically present user, such as rights to navigate in an enterprise product's menus, share content, etc. Moreover, pairing allows the third party device to exchange at least some information with the enterprise device.

    Often, pairing is effectuated by transmitting ultrasound signals from enterprise endpoints to third party devices. The third party device can receive the signal with its microphone and, then, the signal can be decoded with enterprise software and negotiated further with various networking techniques (e.g., Wi-Fi). However, these techniques

have compatibility and robustness issues that frequently limit their effectiveness. For example, if a device cannot detect ultrasound, ultrasound techniques cannot be used. Moreover, these techniques often require hardware installations and/or user interaction (e.g., entering security codes for a Bluetooth pairing).

    Presented herein are techniques to support pairing between third party devices and enterprise devices in a manner that provides increased robustness and compatibility, as compared to the ultrasound techniques. The techniques presented herein utilize information that is "leaked" from displays and display interfaces into parts of the radio spectrum (often, enough information is leaked to be considered a security issue). As is described in further detail below, the techniques provided herein manipulate pixels in a display to control the leaked information to generate a pattern that can be detected by an enterprise device and effectuate a pairing.
