[liberationtech] Enhancing Visual Privacy / Defeating Online Face Recognition

[Brian Conley]

Glad to know you are considering it. It's something I hadn't realized myself
until I started looking at a number of "obscured" photos.

I think its definitely important for us as a community of individuals
promoting security practices to ensure that endusers comprehend the
distinction, and recognize that simply blurring a face, though it may be
enough to prevent the use of an image as "Evidence" in a court of law, that
is not the same as ensuring an image cannot support extra-judicial action or
response from a repressive state actor.
