  We present our ongoing work on developing a system, called DashCam Pay, that
enables in-vehicle payments in a seamless and secure manner using face and
voice biometrics. A plug-and-play device (dashcam) mounted in the vehicle is
used to capture face images and voice commands of passengers.
Privacy-preserving biometric comparison techniques are used to compare the
biometric data captured by the dashcam with the biometric data enrolled on the
users' mobile devices over a wireless interface (e.g., Bluetooth or Wi-Fi
Direct) to determine the payer. Once the payer is identified, payment is
conducted using the enrolled payment credential on the mobile device of the
payer. We conduct preliminary analysis on data collected using a commercially
available dashcam to show the feasibility of building the proposed system. A
prototype of the proposed system is also developed in Android. DashCam Pay can
be integrated as a software solution by dashcam or vehicle manufacturers to
enable open loop in-vehicle payments.
