Looking for a tool to obfuscate information in images

[sci0n]

When you post a picture on social media, the content on the picture is analyzed. On facebook, when you look into the code in the browser console, all pictures in your feed have a descriptive alt tag: "two man, one woman, a bottle" or so.

I want to post a picture that has text in it in large letters, and I need to fuzz the text so that it is still readable to a human but a pure noise to a computer. It apparently can't be just a regular blur, because software these days already knows this form of obfuscation and routinely reverses it. (Found that on Stack Exchange)

I am looking for a tool that will fuzz the image in some more complex way.

I know a tool like this exists because I've seen this as an example of "useless encryption": An image of the Linux penguin was run through that, the result looked like a random nonsense to a computer but to a human it was still obvious that it is a slightly fuzzy image of Tux.

I can't find anything on DDG/Google though. Any pointers?

I don´t know If this is what you´re looking for and it requires you to know Python...

This looks more like steganography (embedding an extra file into an image) but thanks anyway.

I'll try to search Github's python repos, I might find something

Are you talking about the ECB penguin?

That is, are you referring to

this:

Being turned into something like this?

Are you sure Facebook's Computer Vision algorithms won't recognise something like this? Can you try uploading the ECB penguin on Facebook and see what alt text it generates

As for a tool.If this is what you want, you can just replicate the steps that was used to make that ECB tux. Someone described their method here https://blog.filippo.io/the-ecb-penguin/

Also, if this works. Maybe a filter would work just fine. How about trying something like this online filter tool? https://www10.lunapic.com/editor/?action=thermal

Yes, thanks a lot, I'll try it!
