Feature request: multi-blur

lebe-dev opened this issue ยท 4 comments

It would be great to have blur feature to mask sensitive content.

Also I would suggest to do multi-blur effect, not just once.
Security experts introduced method how to recover text after blur.

Usually I do multiple blur over sensitive information, but I do it manually.

Thank you for your project :)

I'm not sure how to pickup a solution which is proven to be safe. I will play with that.
For now you can use a filled rectangle which is 100% safe to use since it totally overrides pixels under it.

It looks like this:

Thanks for suggestion.

Solution for secure blur: apply to selected area blur multiple times in random coordinates :)

A secure and decent option would be

  1. Get the average color of a region
  2. Replace the region with the average color
  3. Blur it, so that there's no noticeable border
