An In-Air Signature Verification System Using Wi-Fi Signals

Abstract

This paper presents a Wi-Fi based system for in-air signature verification. The proposed system is able to authenticate in-air signatures which are captured through Wi-Fi signals. The system consists of four main stages namely, data acquisition, preprocessing, feature extraction and matching. The proposed system shows an average equal error rate of 4.31% on an in-house dataset which consists of 1040 samples collected from 13 subjects. This experiment shows that the Wi-Fi signals can be applied to in-air signature verification effectively.
