Abstract

Currently, the vast majority of smart devices with LEDs are on the rise. It has been observed that the lights emitted by each LED have unique spectral characteristics. Despite the fact that there are a number of methods out there to generate fingerprints, none seem to explore the possibility of generating fingerprints using this unique feature. In this chapter, the method to perform device fingerprinting using the unique spectrum emitted from the LED lights is discussed. The generated fingerprint is then used in device pairing.

Conceptual Model

In this chapter, the method to perform the LED-based device fingerprinting is discussed. In LED-based device fingerprinting, the unique spectrum information of one LED mounted on the first device is saved inside itself. Then, when another device wants to connect, it takes the photo of the light of the LED of the first device, extracts the spectrum from the image, and sends the spectral information to the first device. Next, the first device compares the received spectral data with the one stored inside it. If the information matches, the device generates the pairing protocol, and the two devices become paired. This process is shown in figure 1.
