Biometric System Attacks-A Case Study

The fact that biometric recognition systems are susceptible to different software-related or template is undeniable. Attacks at different vulnerable points in the biometric authentication system are possible. These attacks, however, are not without their flaws. One of two possibilities: either researchers or biometric stakeholders have they may have forgotten or ignored the consequences of these attacks, or they are unaware of some of these threats. In the meantime, if biometric systems lack adequate security, these attacks could result in the biometric system being compromised. The compromise and consequent loss of sensitive personal information, which is irreplaceable and irrevocable, are inevitable. Researchers and biometrics should consider the implications posed by these threats. Over the last two decades, stakeholders have proposed different methods to mitigate some of the attacks. Many of the existing attacks are left unattended, and a large number of them are left unattended. As a result, we deemed it essential to address this issue. The research community is paying attention. The implications of these attacks are highlighted in this article. Exploit the threat approach based on the attacker’s knowledge, and combine them into a single, thorough, and effective attack. Recent state-of-art protection mechanisms that are put forward are included in the comprehensive review. Reduce the impact of these threats. A comparative performance analysis of these protection mechanisms is also performed. It is given that possible countermeasures to the attacks are given. It is expected that this survey will be a success. The biometric template protection research community was woken up by a wake-up call. Hand in glove. Conversely, educating ordinary users and biometric stakeholders about the dangers posed by biometrics.
