With the increasing use of a wide Varity biometric systems in day-to-day work, fingerprints are used for a numerous identity verification application such as ID cards, access control, clock in for attendance, at airport for immigration and security, banks for verification, to unlock phones and laptops and many more. Fingerprints is one of the most widely used biometric system for authentication. The widespread use of fingerprints encourages forgers to create biometric fingerprints as well. Although forgery is less common in these circumstances, it has a significant impact on dactyloscopy.Furthermore, with the advancement of technologies like as 3D printing, the usage of a fingerprint biometric system could represent a security hazard.The primary goal of this research was to investigate fingerprint forgery using dummy fingers manufactured from 3D printed molds and gelatin and glycerin casts.The results were quite shocking that the fingerprints created with these casts were identifiable with the help of the Automated Fingerprint Identification System (AFIS). Also, the dummy finger made with gelatin and glycerin could unlock the phones and the door to restricted area. As a result, the findings of this study emphasize the gravity of the challenge and its impact on the biometric security industry, as well as advice for how law enforcement agencies should deal with such difficulties.One of the suggestions authors gave is that the sensors could be made more sensitive by detecting the heartbeat or body temperature to differentiate between human skin (real finger) and other materials (dummy finger).
