Wireless earphones, in particular, have seen a skyrocketing growth due to its great usability and convenience. With the goal of seeking a more unobtrusive wearable authentication method that the users can easily use and conveniently access, in this study we present EarEcho as a novel, affordable, user-friendly biometric authentication solution. EarEcho takes advantages of the unique physical and geometrical characteristics of human ear canal and assesses the content-free acoustic features of in-ear sound waves for user authentication in a wearable and mobile manner. We implemented the proposed EarEcho on a proof-of-concept prototype and tested it among 20 subjects under diverse application scenarios. We can achieve a recall of 94.19% and precision of 95.16% for one-time authentication, while a recall of 97.55% and precision of 97.57% for continuous authentication. EarEcho has demonstrated its stability over time and robustness to cope with the uncertainties on the varying background noises, body motions, and sound pressure levels.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670320150201860","@type":"Researcher","foaf:name":[{"@value":"Yang Gao"}],"jpcoar:affiliationName":[{"@value":"University at Buffalo, State University of New York, Department of Computer Science and Engineering, Buffalo, NY, USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320150201857","@type":"Researcher","foaf:name":[{"@value":"Wei Wang"}],"jpcoar:affiliationName":[{"@value":"University at Buffalo, State University of New York, Department of Computer Science and Engineering, Buffalo, NY, USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670320150201858","@type":"Researcher","foaf:name":[{"@value":"Vir V.
