A company plans to replace proximity badge readers with palm-print scanners at doors leading to its data center. Which benefit most directly explains why palm-print authentication provides stronger protection than the older badge system?
It requires no additional hardware beyond the existing badge readers.
It eliminates the need to store any user credentials or templates in a database.
It provides a high level of assurance because palm patterns are unique and very difficult to duplicate.
It continues to authenticate users accurately even when they are wearing gloves.
Palm patterns are unique to each individual and reside beneath the skin, making them very hard to image or replicate. A successful match therefore strongly indicates the person is who they claim to be, whereas badges can be lost, stolen, or cloned and PINs can be shared.
Why the other options are wrong:
Specialized scanning hardware is required, so existing badge readers cannot be reused.
The system must store an encrypted template of each user's palm for future comparisons, so credentials are still maintained.
Palm-print readers need a clear view of the hand; gloves block the surface lines and prevent accurate imaging.
