Abstract
Continuous authentication is used to detect identity theft and to confirm the identity of a person. Continuous authentication using keystroke information, a type of biometrics, is a stress-free method that does not cause interruption of the work of the person being authenticated. In this paper, we present a model of continuous multimodal authentication using features obtained from a keyboard, a microphone, and a webcam, which are commonly used for external devices. This paper discusses the processing model we have built with the goal of realizing a processing model for the Enter key operation in free text input .
