Multimodal Personal Ear Authentication Using Acoustic Ear Feature for Smartphone Security

Shunji Itani et al.

Summary: In recent years, biometric authentication technology for smartphones has become widespread, with fingerprint authentication and face recognition being the mainstream methods. However, these methods have limitations in specific situations. This paper proposes a multimodal personal authentication method based on the pinna-related transfer function (PRTF), and demonstrates its effectiveness and robustness through experiments.

INDIVIDUALIZED HEAR-THROUGH FOR ACOUSTIC TRANSPARENCY USING PCA-BASED SOUND PRESSURE ESTIMATION AT THE EARDRUM

Wenyu Jin et al.

Summary: The hear-through functionality on hearing devices has gained great attention from researchers due to its ability to provide open-ear equivalent hearing while allowing modification of sound pressure at the eardrum. However, designing equalization filters for this purpose requires precise knowledge of all relevant acoustic transfer functions, including the challenging transfer function between the hearing device receiver and the eardrum. In this study, an individualized hear-through equalization filter design is proposed, which leverages a principle component analysis based estimator to predict the sound pressure at the eardrum using measurements from the secondary path. Experimental results confirm the good sound quality achieved by the proposed method compared to traditional filter designs.
