Alan is evaluating different biometric systems and is concerned that users might not want to subject themselves to retinal scans due to privacy concerns. Which characteristic of a biometric system is he considering?

Acceptability T/F

Acceptability - True.

Explanation:

Bio-metric systems are demonstrated as the technological system that employs body/physical information or calculations to identify a particular person. Such systems are primarily employed by institutions for security reasons and various other purposes like keeping a record of the identity of their employees through their biological data like fingerprints, retina, etc.

As per the question, Alan's evaluation of the problem that 'users might hesitate to provide their physical data to a specific organization' as some of them might not be able to accept the technology or willing to provide their biological traits. Thus, Alan is rightly considering the 'acceptability' characteristic of bio-metric systems which may not be acceptable to all.
