High throughput passenger identification in portal monitoring

A method for high throughput passenger identification in portal security, the method comprising:

• activating an image acquisition device disposed at a portal passageway leading into a secured area, the image acquisition device continuously acquiring imagery at the portal passageway and transmitting the acquired imagery to a display also disposed at the portal passageway;
• receiving in memory of a host computing system from the image acquisition device as part of the continuously acquired imagery a contemporaneously acquired image of a group of individuals approaching the portal passageway;
• identifying a set of faces of the group of individuals in the contemporaneously acquired image;
• querying a database of faces with each identified face in the set and for each face assigning a confidence value of having matched the face to a record of a known person in the database;
• visually decorating each face in the contemporaneously acquired image with an initial visual characteristic on condition that a correspondingly assigned confidence value falls short of a threshold, but with a different visual characteristic on condition that the correspondingly assigned confidence value does not fall short of the threshold;
• and,
• displaying the contemporaneously acquired image as part of the continuously acquired imagery in the display.

A computer program product for high throughput passenger identification in portal security, the computer program product including a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to perform a method including:

• activating an image acquisition device disposed at a portal passageway leading into a secured area, the image acquisition device continuously acquiring imagery at the portal passageway and transmitting the acquired imagery to a display also disposed at the portal passageway;
• receiving in memory of a host computing system from the image acquisition device as part of the continuously acquired imagery a contemporaneously acquired image of a group of individuals approaching the portal passageway;
• identifying a set of faces of the group of individuals in the contemporaneously acquired image;
