What kind of error occurs when a biometric access system falsely accepts an unauthorized user?

1. Type I

2. Type II

3. Type III

4. Type IV

The correct answer is: Type II

A biometric access system that falsely accepts an unauthorized user is experiencing a Type II error. In the context of biometric systems, a Type II error, also known as a false acceptance or false positive, occurs when the system incorrectly identifies an unauthorized individual as an authorized user. This type of error undermines the security of the system, as it could allow someone without legitimate access to gain entry to secure areas or information. Biometric systems strive to minimize this risk, as a high false acceptance rate can lead to significant vulnerabilities. Type I errors, in contrast, involve a false rejection of an authorized user, meaning legitimate users are incorrectly denied access. Understanding the distinction between these errors is critical for designing and implementing effective biometric security measures. Recognizing Type II errors is essential for improving system accuracy and enhancing overall security.
