We propose a information presentation system using face recognition which provides information of the person whom the user met previously. This system extracts a face region from camera images, and then search the database using the face as a query, and presents information about found person. If the face has not been registered in the database, the system registers the face as a new person. A face region is extracted by the classifier using Haar-like features and face recognition is done by the eigenface method. The system update the database by registering used query image as new face image.
