Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we consider personal authentication technology using individual differences of acoustic transfer function measured from the pinna ; the Pinna Related Transfer Function (PRTF). In addition, in this paper, considering the convenience in practical use, a smartphone that is not necessary to be worn on the pinna for each authentication is used to measure PRTF. However, it is known that in the case of using a smartphone, PRTF changes according to the emission direction of measurement signal toward the pinna, so the authentication rate is lower than that of using earphones and headphones. In this paper, the position information of the smartphone is measured by the acceleration sensor and proximity sensor and used together with the PRTF for learning at the same time. We demonstrate that the proposed authentication can manage the changes in the emission direction of each measurement and improve the robustness.
