Facial recognition is a biometric technology that identifies or verifies individuals by analyzing their facial features. It uses computer vision and machine learning techniques to detect and compare faces in images or videos against a database.
Facial recognition is widely used in security systems for access control, surveillance, and identity verification. It’s also common in consumer applications, such as unlocking smartphones, tagging friends in photos, or creating personalized experiences.
Despite its benefits, facial recognition raises privacy concerns, emphasizing the need for ethical use and robust data protection.
