New features of the Rock 3D facial authentication include tailgating notification and mask detection. The Rock distinguishes an authorized user from an unauthorized user as they approach an access point or door together and can be set to immediately alert upon the attempt at unauthorized access. Another feature, facemask detection, was added in response to increasing mandates calling for businesses to require all occupants to wear masks. The Rock detects whether a user who is seeking access is wearing a facemask. The Rock is not used for surveillance and does not covertly or non-cooperatively collect or store images of individuals who have not enrolled in the system.
