This paper presents the development and the evaluation of a biometric device using IntraBody Communication (IBC). The receiver is presented as a mobile phone casing and can be plugged into a smartphone. The emitter is a fixed antenna whose distance to the user hand may vary in time, depending of the user’s movements. The main objective of this device’s development is to evaluate whether the gesture of approach and contact the antenna is an inter-individual signature. A comparison is made between conventional IBC devices and our prototype (called Orange prototype). A preliminary study for evaluating the feasibility of biometric identification using the proposed device is also developed in this paper.
