Why ? because some one could stole my money or because someone else could log in without my authorization? What if there is a way to prevent that without PIN or private key ?
What other way of preventing that do you propose? Fingerprint? I will will send the data of fingerprint. Facial recognition? I will just grab your profile picture. What kind of method do you envise that could prove you are you and not somebody malicious?
Here is another example: some people argue for privacy because the information can be used to criminalized gay people.
Well then fix the criminalization of gay people instead of trying to hide the fact that they are gay.
>Facial Recognition?
That could be one way
> I will just grab your profile picture.
Then maybe fix it to detect whether its a real person or just a picture.
Or maybe there are better way, I don't know.
Like I said, I'm not the expert, I wouldn't know every solution to every problem.
My point is we should spent the effort on figuring out that problem instead of trying to keep thing hiding.
You say "just fix it to detect whether it's legit data" - how? Deep fakes are getting better by the day, we already have problems with recognizing them ourselves.
Again, I'm not the expert, every situation will may require its unique solution.
>You say "just fix it to detect whether it's legit data" - how
Yes this my attempt to at least give a hint with my far from expert knowledge.
My point is we should spend our effort to solve this instead of trying to make information private.
No, this isn't a hint, because I already stated why it wouldn't work: thief will just use publicly available data and create deep fake to mimic the owner of the bank account.
If we had technology which could magically determine whether received data is genuine, the only safety check would be "Are you an owner? [y/n]"
> My point is we should spend our effort to solve this instead of trying to make information private.
Again, nobody sane ever have spend any effort on something without even a hint for it being possible. I am asking: what's your argument to even think it's possible?
It'd be fascinating to watch someone to try and recreate concepts from cryptography without the crypto though!
