Which method of biometric attack involves submitting numerous different biometric samples to the capture device?

The method of biometric attack that involves submitting numerous different biometric samples to the capture device is known as a brute force attack. In this context, the attacker attempts to gain unauthorized access by systematically trying a vast number of biometric inputs, such as fingerprints or facial recognition patterns, until one successfully matches a stored template.

This method relies on persistently generating and testing multiple inputs to find a valid one, which effectively exploits the weaknesses in biometric authentication systems that may not have robust countermeasures against repeated submissions. The process involves trial and error, and it can be resource-intensive, but if the system does not have sufficient security measures in place, it can succeed.

Understanding brute force attacks in biometric systems emphasizes the importance of incorporating defenses such as liveness detection, limiting the number of attempts, or employing multi-factor authentication to bolster security against such vulnerabilities.
