Sir, – I see that the latest update of the Apple iPhone system (version iOS 15.4) includes the ability for facial recognition to work if people are wearing masks. This enhancement will add benefits to the user experience of some, but it must also beg further questions for all about the invasiveness of digital technology in being able to detect, match, and store our uniqueness. – Yours, etc,
