In this chapter, you learned that an authentication system can be more than a simple face recognition interface by using multiple biometric properties of the person trying to authenticate. We showed you how to perform iris and fingerprint recognition using the OpenCV library to make a multi-biometric authentication system. One can add even more biometrics to the system, since the possibilities are endless.
The focus of the chapter was to get people interested in the power of biometrics and the endless possibilities of the OpenCV library. If you feel inspired by this, do experiment further and share your thoughts with the community.
