Question

An amusement park is implementing a biometric system that validates customers' fingerprints to ensure they are not sharing tickets. The park's owner values customers above all and would prefer customers' convenience over security. For this reason, which of the following features should the security team prioritize FIRST?

1) Low FAR
2) Low efficacy
3) Low FRR
4) Low CER

Answer 1

The security team should prioritize Low False Acceptance Rate (FAR) to ensure only authorized customers are granted access to the amusement park. This helps maintain security and prevent ticket sharing.

Step-by-step explanation:

The security team should prioritize Low False Acceptance Rate (FAR) first in order to ensure that only authorized customers are granted access to the amusement park. Low FAR means that the biometric system will have a lower probability of mistakenly accepting the fingerprints of unauthorized individuals as valid. This is important to maintain security and prevent ticket sharing.

While convenience is valued, it is crucial to prioritize security to protect both the amusement park and its customers. Low FAR ensures that only genuine customers are granted entry, reducing the risk of fraud or unauthorized access.

Once a low FAR is achieved, the security team can then prioritize other factors such as low False Rejection Rate (FRR) to prevent valid customers from being mistakenly rejected, low Equal Error Rate (CER) which measures the balance between FAR and FRR, and high efficiency to ensure quick and hassle-free authentication.
