Abstract: In an increasingly digital world, protecting confidential information from hackers and unauthorized individuals is becoming more difficult and the need for robust security is paramount. As a result, Biometric spoofing is a growing concern as biometric traits are vulnerable to attacks. Biometric spoofing is the ability to fool a biometric system into recognizing a fake user as a genuine user by means of presenting a synthetic forged version of the original biometric trait to the sensor. Specific countermeasures that allow biometric system to detect fake artefacts and to reject them need to be developed. This paper’s main goal is to provide an overview of different antispoofing techniques used in the now emerging field of antispoofing with special attention to face modality.

Keywords: Biometrics, spoofing, antispoofing, antispoofing techniques.
