Abstract. Class attendance system is widely used in colleges and universities to maintain the students' attendance. In this paper, we proposed a new framework of class attendance system. With the use of base station location services that could quickly determine whether students to class and use the face recognition and dynamic decision to prevent cheating. The system could save the class time and finish the statistics of the class and could realize real-time statistics and feedback quickly. That could provide effective technical support for real time control of the teaching situation for the teachers and the teaching department. It could also save a lot of roll call time and the statistical work after class. With the user authentication methods based on face recognition and dynamic facial features tracking, it could effectively prevent generation, alternative phones, and virtual positioning forging method
