Use of recognition-based technology to count passengers using the security screening service
The purpose of this notice is to advise you of the trial of recognition technology to count the number of passengers using the security screening service and to produce a wait time for the security screening service so passengers know how long they can expect to wait in the queue.
This trial was extended due to recent COVID-19 travel restrictions leading to a decline in passenger volumes, and ended 19 October 2021. A full evaluation of the system is being undertaken before any recommendation is developed for further operational use.
Cameras will capture an image from a video feed of you entering the security screening queue. The face biometric data from the image will be converted to a digital signature (numbers) and the image deleted.
The digital signature is retained in a temporary memory cache in a secure government dedicated server only for the duration that you are in the queue. When you exit the queue another camera records your exit, creates another digital signature and matches your exit with the digital signature of your entry.
The information will be used to compile a wait time that is displayed for other passengers so they know how long they can expect to wait in the queue, and produce a count of the number of passengers using the security screening service.
The images of your entry and exit are deleted after the digital signatures have been created, and the digital signatures are then deleted after you exit the queue. No other use is made of the video feed or digital signature other than to count the number of passengers passing through the security screening area.
There is no image or digital signature retained of the fact that you have used the security screening service.
As no image or digital signature of you is retained after you have exited the queue there is no personal information retained that you can request access to, or correction of.
