In today’s world security is main concern for every place. The unauthorized of entry of unknown people into an office creates huge risk. This will lead to loss of security. We cannot manually monitor entry of people and authorizing them. Security officials cannot check everyone entering into an office. It is a time consuming process too. Some technologies such as face recognition and fingerprint detection systems help us to do such security operations. The face recognition system helps in differentiating the face textures of various faces. This will help an organization to be safe by allowing only the authorized persons of that organization. Even within some restricted areas the entry of every person can be restricted by this system. This technique is also applied in some laptops. This makes only the owner of the laptop to access it. Every point of the face is observed by the technique for recognizing the face of the person who wants to enter into an area of an organization. The facial features like distance between the eyes, color of eye, cheeks are checked. The nodal points is the important feature which helps in recognizing the face. The simple text password can be copied by other person. But one’s face texture cannot be copied easily.
