The timing of the release of this tool seems a bit innapropriate, given the state of rioting in a few US cities now. It's going to be incredibly draining on law enforcement in the US for a few years to identify and prosecute criminals involved in riots. Most victims already who have lost their homes, their businesses, and even their loved ones will mostly likely never see the criminals brought to justice given the sc…

Peaceful protest is being squashed and de-legitimized. This is the flowering of fascism.
Earlier quoted context omitted.
When I hear your first point, I consider the possibility that these are not retaliatory murders, but rather ways to keep something secret. If there was an agenda behind these riots organized at a higher level than these leaders, similar to what is being suggested by some during these current protests, and those higher level organizers wanted to keep the agenda or those who set it hidden, it could explain why lower le…
> When I hear your first point, I consider the possibility that these are not retaliatory murders, but rather ways to keep something secret. That contains as much conspiracy as "somebody is hunting down the protestors". There are simpler possible explanations, I believe, e.g. people who join (or organize) riots are usually not the stable boring kind that live long, predictable lives full of planning and quiet afterno…

Good. Black people factually live under an authoritarian regime in the US.
Can someone package this as an iOS and Android app and get it into the app stores?
There are also a few that do face detection and blur on the AppStore.
How resilient is blurring against deconvolution?
> How resilient is blurring against deconvolution? This depends a lot on the implementation details. If you blur an image using arbitrary-precision real numbers, then blurring is invertible. If you add a bit of random noise, or quantize your pixels into a finite-precision data type, then it becomes essentially one-way, and you cannot recover the original image.
Technically you are correct - you cannot recover the exact original image. The same is the true for saving an image as JPEG. But the question at hand is whether you can still recognize faces, not whether you can restore a byte-for-byte of the original. And whether JPEG or blurring, the answer is generally "yes".
It does depend on the implementation (and whether you know the implementation) how close you can get.
1) The code, for now, runs locally. This is good. To avoid the possibility of the code being tampered with at a later day (for example, it could be modified to send copies of the image to a server), download the webpage and use the saved copy, not the live copy.
2) Do not use the blur functionality. For maximum privacy, this should be removed from the app entirely. There are _a lot_ of forensic methods to reverse blur techniques.
3) Be weary of other things in the photograph that might identify someone: reflections, shadows, so on.
4) Really a subset of 2 and 3, but be aware that blocking out faces is often times not sufficient to anonymise the subject in the photo. Identifying marks like tattoos, or even something as basic as the shoes they are wearing, can be used to identify the target.
Some tips to maximise user privacy while deploying this tool: 1) The code, for now, runs locally. This is good.

Any examples? You can't reverse it if the data is gone.
