Abstract: Biometrics are unique, measurable characteristics of an individual that can be used to automatically recognize an individual or to verify an individual's identity. Biometrics can measure both physiological and behavioural characteristics. Physiological biometrics (based on measurements of parts of the human body and data obtained from direct measurements) include finger scans, face recognition, iris scans, retina scans, and hand scans. Everything happens online as technology advances around the world. Facial recognition systems are used to identify people in photos, videos, in real time, etc. It is a category of biometric security. It provides an environment with privacy and authentication that helps organizations keep their data safe. It can be used for security, authentication, identification, accuracy and many other benefits. It can also be used because it is a non-contact, non-invasive procedure. In addition, facial recognition systems can also be used for attendance assessment in schools, colleges, offices, etc. Since the conventional manual attendance system takes time and effort to maintain, it can be used as a class attendance system that uses the concept of face recognition or for attendance scoring within the company, minimizing the burden on administrators. I can. Attendance is on your own and no substitutes are allowed. Therefore, the need for this system is increasing. The system consists of four phases: recording, training, facial recognition, and attendance update. A record is created when a new user uses the software to enroll their face and is assigned an ID. During training, the dataset created is used as input to a training model that uses a k-NN classifier to classify the images present in the datase
