Except, it seems, in Brazil. You learn something new every day

Why?

Yes, many. In most cases a trained doctor has a moral, and maybe contractual, responsibility to help some one, not a legal one. There is no law that says ‘you are trained doctor, you have to help fix this broken leg’. Now if you egregiously refuse the various medical licensing authorities might take a dim view and you might loose your license to practice, but that’s not the same as breaking the law

I think that’s exactly how it’s going to work - you can’t force all ‘fake’ sources to have signatures- it’s too easy to make one without one for malicious reasons. Instead you have to create trusted sources of real images. Much easier and more secure

Good article- thanks
