Facial recognition technology is a type of software that can identify or verify a person by analyzing their facial features. It works by capturing an image of a face and comparing it to a database of known faces. This technology is commonly used in security systems, smartphones, and social media platforms to enhance user experience and safety. The process involves several steps, including detecting a face, extracting key features, and matching them against stored data. While it offers benefits like improved security and convenience, it also raises concerns about privacy and potential misuse, prompting discussions about regulations and ethical use.
