Comparative Review of Earlier Research on Multimodal Biometric Authentication Using Ear and Palm Print

Abstract

Biometric authentication systems have gained prominence due to their ability to provide secure and reliable identity verification. Among various biometric traits, ear and palmprint recognition have shown significant potential due to their unique and stable features. This review paper explores the integration of ear and palmprint biometrics in a multimodal authentication system, examining their individual characteristics, advantages, challenges, and the synergistic benefits of their combination. We also discuss recent advancements, methodologies, and future directions in multimodal biometric authentication using ear and palmprint.
