Accidental new born swapping, health-care tracking, and child-abduction cases are some of the scenarios where new born face recognition can prove to be extremely useful. With the help of the right biometric system in place, cases of swapping, for instance, can be evaluated much faster. In this chapter, we first discuss the various biometric modalities along with their advantages and limitations. We next discuss the face biometrics in detail and present all the datasets available and existing hand-crafted, learning-based, as well as deep-learning-based techniques which have been proposed for new born face recognition. Finally, we evaluate and compare these techniques. Our comparative analysis shows that the state-of-the-art SSF-CNN technique achieves an average of rank-1 new born accuracy of 82.075 %. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
