An organization is replacing proximity badges with palmprint scanners at critical entry points. Which of the following is the PRIMARY advantage of palmprint authentication over these traditional methods?
It eliminates the need to store any user credentials or templates in a database.
It requires no additional hardware beyond the existing badge readers.
It continues to authenticate users accurately even when they are wearing gloves.
It provides a high level of assurance because palm patterns are unique and very difficult to duplicate.
Palm patterns are extremely difficult to copy or spoof, so using a palmprint scanner greatly increases the assurance that the person presenting the credential is the authorized individual. Proximity badges can be lost, stolen, or cloned, and PINs can be shared or observed, but a person's unique palm geometry and vein pattern cannot be easily duplicated.
Why the other options are wrong:
Requiring no additional hardware beyond existing badge readers is false; palmprint scanners are specialized devices.
Templates of users' palms must still be stored in a secure database for comparison, so credentials are not eliminated.
A palmprint scanner cannot read through gloves; users would need to remove them.
