Biometric Authentication: Biometric authentication
                    is a process in which biological characteristics such as
                    finger print, face and retina are used for identifying
                    the identity of an individual. In this process, a
                    biometric machine is used to capture the biological
                    details of a person and compare these details with
                    the existing details, which are  stored in computer.
                    Biometric systems offer an automated and reliable
                    way of recognizing a person's identity based on
                    characteristics that are difficult to replicate, providing         Biometric Authentication
                    an added layer of security. Some different types of
                    biometric authentication are as follows:
                     (i)   Face  Recognition:  Face  recognition  is the
                        process to identify an individual by using his/her

                        facial features. A biometric machine captures the
                        facial image or video of person's face. This image
                        is transformed into a unique faceprint. The image
                        is transformed using a techniques  such as deep
                        learning algorithms to map facial landmarks. The
                        resulting faceprint is sent to a back-end database
                        for comparison against stored templates to find
                                                                                          Face Recognition
                        a possible match. Face recognition is widely used

                        in smartphones for secure authentication.

                           Biometrics were used during prehistoric times.
                           Chinese used finger prints in the 14th century for identification.

                           In the 17th century, finger prints were used to seal official documents.




                     (ii)   Iris and Retinal  Recognition:  Biometrics  that analyse the complex and unique
                         characteristics of the eyes can be divided into two different types:

                            Iris  biometrics:  The  iris is the  colouredart  of  the  eye  surrounding  the  pupil.  Iris
                           recognition systems capture a video image of the iris, and the data is compared to
                           stored templates to verify identity.
                            Retina biometrics: Retina is the layer of blood vessels at the back of the eye. In retinal
                           recognition, an infrared light beam scans the retina’s unique pattern of blood vessels.
                           The captured data is then compared to the stored template to authenticate the user.
                           By using modern biometric technologies like face, iris, and retinal recognition, systems
                           can provide enhanced security and convenience for users.
