Authentication methods for important parts of the face are one of the modern biometric systems. These tools are based on the identification of the person through the unique geometric and visual analysis of the human face. The face is realized by deep algorithm technologies with the help of different forms of artificial intelligence, neural tools based on learning ability. These authentication methods are mainly used in smartphones, computers, and government services. In this topic, the main principles of facial recognition technology, the working process, technological and material aspects are covered. Their problems, such as faking facial images or cheating the system, are discussed. The abstract discusses facial image processing, data protection, and their software solutions.
