[liberationtech] Enhancing Visual Privacy / Defeating Online Face Recognition

Hey Brian,

Bryan from WITNESS here.  I completely agree with your assessment, and I
would guess that most of us would agree that technology can never truly
replace good face to face safety and security training or implementing good
protocols for filming like the ones you mentioned.

The ObscuraCam doesn't set out to replace training and/or best practices,
but rather to introduce these concepts to a wider activist audience, as well
as to raise awareness and generate discussion around the idea of "visual
privacy."

That said, we do hope include a fair amount of information within the app
about best practices and other safety and security features, that I'm sure
we'll be in discussion about.

Thanks for the tips and hope to speak soon,
Bryan

PS.  Just a quick link to some basic filming tips from WITNESS:
