I recently found myself in a position where I had to blur a ton of faces from multiple pictures (about 100/day).

It’s really tedious to do it manually and something like OpenCV shines.

We found a repo [1] with python code that automatically detects and blurs faces. This script was one of many, except it had a very high accuracy. Over 90%.

Removing exif data is a great idea.

This is great for some situations. However, my personal policy is to upload my protest content to Google Photos asap (if appropriate). This makes sure your content is off your device if your phone gets confiscated AND it provides (be it thin) layer of authenticity/validation of the content.

For meta data, exiftool is handy for removing metadata[0].

$ exiftool -all= foo.jpg

And even better, save image first as .bmp or other format that doesn’t support metadata. Then reload and convert to jpeg, and run the exiftool on this image.

Can't they find photos from others, examine the angle of your photos and prove it was you that took the pictures? They can also subpeona your carrier for records indicating you were a location at a certain time.

I can see some diligent prosecutors going back and looking at data to gather evidence.
