A company is upgrading its authentication system by adding a biometric factor to its existing password policy. The security team's primary concern is preventing authentication bypass using simple spoofing methods, such as high-resolution photographs or voice recordings. Which of the following solutions BEST addresses this specific concern while being a widely adopted and mature technology?
Fingerprint scanning is the best solution in this scenario. It is a mature biometric technology that is not susceptible to spoofing from photographs or voice recordings, directly addressing the company's primary concern. While some facial recognition systems can be spoofed with high-quality images, advanced versions include liveness detection to prevent this. Voice recognition is particularly susceptible to being bypassed with recordings. A key fob is a possession-based factor ("something you have"), not a biometric factor ("something you are"), so it does not meet the requirement for a biometric method.
