SVM-Based Biometric Authentication Using Intra-Body Propagation Signals

To use intra-body propagation signals for biometric authenticationhave been proposed. The intra-body propagationsignals are hid in human bodies; therefore, they havetolerability to circumvention using artifacts. Additionally,utilizing the signals in the body enables liveness detectionwith no additional scheme. The problem is, however, verificationperformance using the intra-body propagation signalis not so high. In this paper, in order to improve the performancewe propose to use user-specific frequency bandsfor all users in verification. The verification performance isimproved to 70 %. Furthermore, we introduce the supportvector machine (SVM) into the verification process. It isconfirmed that verification rate of about 86 % is achieved.
