Remember, no one first asked any of us for our permission to be tracked by our physical features just for walking down the street and going about our daily business as we've always done, nevertheless this all-pervasive technology was introduced without our permission nor with any public debate.
I posted this comment several hours ago in a duplicate of this story. Having now had time to think about it, I seriously believe we're just beginning to see the beginnings of a new war on privacy and that this new technology has now given ordinary people the means of fighting back. If this war escalates because of criminals/bad actors then don't blame us—we didn't start it:
"Perhaps we'll all be wearing them sooner than we think out of necessity to counter facial recognition.
(It's just occurred to me that a blank conformal OLED version of the mask would be the ultimate form — one's face could dynamically change on-the-fly whilst one's out and about. That would give all-pervasive surveillance systems a decent run for their money.) ;-)"
It seems to me that the cat's now out of the bag thanks to unfettered/unregulated access to facial recognition by all and sundry.
Also, I would not call those Japanese masks "hyper realistic", unless the defintition of "realistic" has changed recently. There are better, much more realistic masks out there.
They'll run it through face recognition and find the original person that provided their face data and arrest them.
Plot twist, a criminal will flood the market with masks of their own face to get plausible deniability for the actual crime.
