Hello, personally I've signed the EU pedition https://reclaimyourface.eu/
to prevent allowing computers to automatically identify use everywhere. I believe such systems would have a bad effect on our democratic society here in Europe.
No, it won't be enough to make the software running facial recognition software Free Software. (It is good to do so, because it helps researching the abilities) Just like it is forbidden by law to read other peoples mail or listen to their conversations, we probably need a law to rule out mass surveillance by software.
I hope you'll sign and spread the word, too.
Best Regards, Bernhard ps.: Die privacy laws about conversations and email could also be better.
