A person authentication system using second minor finger knuckles for door handle

摘要

This paper proposes a person authentication system using second minor finger knuckles, i.e., metacarpophalangeal (MCP) joint, for a door handle. The proposed system can be constructed by attaching a camera on a door handle. Region of interest (ROI) images around each MCP joint can be extracted from only one still image, since MCP joints are located on the front face of the camera. Through a set of experiments, we demonstrate that the proposed system exhibits the efficient performance of MCP recognition and also show the potential possibilities of minor finger knuckles for biometric recognition.
