EarPass: Secure and Implicit Call Receiver Authentication Using Ear Acoustic Sensing

arXiv:2404.15000v1 Announce Type: new
Abstract: Private voice communication often contains sensitive information, making it critical to ensure that only authorized users have access to such calls. Unfortunately, current authentication mechanisms, such as PIN-based passwords, fingerprint recognition, and face recognition, fail to authenticate the call receiver, leaving a gap in security. To fill the gap, we present EarPass, a secure and implicit call receiver authentication scheme designed for smartphones. EarPass sends inaudible acoustic signals through the earpiece speaker to actively sense …
