Title
WiPIN: Operation-free Person Identification using WiFi Signals.
Abstract
Person identification is critical for sensitive applications such as system login/unlock, access control and payment. In this paper, we present an operation-free person identification system, namely WiPIN, that identifies biometric features of users using Wi-Fi signals. Our approach is based on an entirely new insight that different persons have distinct effects, including the absorption and reflection, on the Wi-Fi signals. We show that through effective signal processing and feature extraction/matching designs, the Channel State Information (CSI) used in recent Wi-Fi protocols can be utilized for person identification without requiring any collaborative operations, such as wiping, walking, or speaking. We theoretically analyzed the interaction between the human body and Wi-Fi Signals via an interactive model. We proposed a mapping rule between variation patterns of Wi-Fi signals and human biologic features, and demonstrated the feasibility of establishing CSI based person identifiers. We conducted extensive experiments over commodity off-the-shelf Wi-Fi devices. The results show WiPIN achieves 92% accuracy in person identification over a group of 30 users, with sufficient robustness to environment noises.
