Facial recognition software is a technology that identifies or verifies a person’s identity using their facial features. It works by analyzing the unique patterns of a person's face, such as the distance between the eyes, the shape of the jawline, and other distinct characteristics. This software is commonly used in security systems, smartphones, and social media platforms to enhance user experience and safety. The technology relies on algorithms that compare a captured image to a database of known faces. If a match is found, it can confirm the person's identity. While useful, facial recognition software raises privacy concerns and ethical questions regarding surveillance and data security.
