Facial recognition is a technology that uses biometric software to identify or verify a person's identity based on their facial features. It works by analyzing and comparing unique facial characteristics such as the distance between the eyes, the shape of the nose, and the contours of the face. This technology has applications in security, law enforcement, and consumer electronics, among other industries. Facial recognition has the potential to be a powerful tool for identifying individuals, but it also raises concerns about privacy, surveillance, and potential biases in the algorithms used.
