摘要

In this study, we attempt personal authentication using steady-state visual evoked potentials (SSVEPs), a type of evoked electroencephalographic brain activity generated by external visual stimuli. We recorded SSVEPs induced by a 5-Hz light stimulus from 16 participants. Recordings were from four electrodes, and multivariate autore-gressive coefficients were used as features for authentication. Subsequently, classification based on the Mahalanobis distance was performed using the multivariate autoregressive coefficients. The authentication was performed under two conditions: 1) considering only those registered in the database and 2) considering unregistered third persons. Furthermore, we examined the effectiveness of the voting process, in which the person is authenticated on the basis of voting on multiple test samples. When authentication proceeded using only registrants, accuracy was higher when four electrodes were used than when two electrodes were used, and the voting process improved identification accuracy to 96.4%. Authentication using unregistered third persons was also more accurate with four electrodes than with two electrodes. The accuracy was 75.8% when voting was not applied and reached 90.4% when voting was applied. Our method, which can authenticate an individual in just a few seconds, is considered effective for realizing personal authentication by SSVEP.
