Strong authentication mechanisms are critical to ensuring the security of smart lockers. By requiring multiple forms of identification before access is granted, the smart lockers help ensure that only authorized individuals can access the sensitive removable media. This is especially important in a data center environment, where media access needs strict control. Although automatic notifications of unauthorized access attempts add an extra layer of security by alerting administrators, the primary objective of smart lockers is to prevent unauthorized access in the first place through robust authentication. Interior cameras and availability during power loss are supplementary to this primary function and may not be as critical as ensuring that the access control itself is secure.
