It seems it is no longer secure to blur face. It is possible to use image processing techniques to unblur or reconstruct a face, and facial recognition technology may still be able to identify a person even if their face is blurred (this is also highly depends on the blur algorithm). References: h…

At this time, both PrivacyBlur’s GitHub repository and website (both already linked here ) return 404 errors, rendering the source code unavailable. It’s definitely not an issue with GitHub uptime. So technically, it doesn’t meet this criterion for data redaction tools Apps developed for open-sou…

It does appear to be unmaintained, do we have any replacement suggestions?

it hasn’t been updated in a few years, but ObscuraCam comes to mind. similar face detection software from the guardian project, with multiple options for it including redacting (with solid color, and other options)

The only “maintained” service that comes to my mind is… Signal, since you can take a photo and blur the face or draw in the face to hide it with something like Note to Self Another method is using the device’s built-in blur tool, but that’s very device-specific. AFAIK, Samsung and Pixels have that …

As far as I know this app still works though, I don’t think we should be too quick to remove seemingly unmaintained apps simply because they haven’t been updated in a while. If an OS update breaks PrivacyBlur it may still receive a patch in the future for example, we don’t really know until that hap…

[image] jonah: If an OS update breaks PrivacyBlur it may still receive a patch in the future for example, we don’t really know until that happens. True enough I guess. The only issue can be if apps depend on old API levels it creates a lot of work for developers to catch up when those are dep…

Also, we do already have a warning about blurring text. You didn’t check the research paper? It’s not specific to text only, faces too etc. Being unmaintained is something that was discussed later in the thread, not the initial post by OP. Also dev said it won’t be updated for now Maintaince sta…

Also, the target sdk of this aplication influences its security? Because PrivacyBlur targets sdk 30 according to Aurora Store.

Also, is it possible to add a little warning below the PrivacyBlur recommendation? To mention the security issues of blurring your face.

Reading through the linked paper and other resources, I don’t think concrete security issues with face blurring have actually been identified, especially with the pixelate filter (as opposed to gaussian blur) present in this app. If we want, I’d be fine with amending the existing warning to say: B…

Yes, I’m definitely fine with that.
