Not ‘people’ but AI-assisted gait analysis. Scan of video footage identifies points on body, tracks movement of those points through space, represents this as output of an algorithm, which generates a result (e.g. a long sequence of numbers like a barcode) which is unique to you. They cannot i.d. you by name and address unless they have your biometrics on record but it is a potential way to identify you just like fingerprints or dna and will stay on record and might hurt you in future.
