Do you use pixelation or blurring software to obscure stuff?

Especailly in JPEGs?

Researchers find that standard pixelation methods applied to JPEGs can have faces and text reliably identified by machine learning systems.

the algorithm had 71% accuracy (or 83% if allowed to guess five times). The algorithm doesn’t produce a deblurred image—it simply identifies what it sees in the obscured photo, based on information it already knows.

.....

Companies like YouTube that recommend blurring should make it clear that their privacy measures only protect information from humans, not machines or determined adversaries, say McPherson and Shmatikov.

Better break out those wide black markers (or their Photoshop equivalents).

Can you pixelate a single pixel?

Well great. Remember just a few years ago when computers couldn't use semantics?

So it guesses what was in the blurred area based on context. Neat.

Yeah. In terms of social graces, this puts computers ahead of several people I know.

Its not guessing. It shares nothing, has no social network, no culture, or world it is immersed within and moves about to adapt towards and cope with. These are the ways meaning gets embedded with the abstracted representations creatures create and use to communicate with. So whats going on has nothing to do with that. Its simply a good example of a well designed tool that is able to perform mindless tasks and give back results useful to the people who wanted to obtain them.

Who knew one pixel could do so much.
