There is a program I've used for years called Beyond Compare. It's not free, but it's cheap. https://www.scootersoftware.com/

If you don't want to pay, you could search for free alternatives to beyond compare and likely find what you're looking for.

Thanks for the tip. That looks like it might do what I want.

Not easily because the combinations will be enormous if you didn't know what kind of data you're trying to find. If you're talking about images containing other files similar to ThePGPkey located in the epstein photo you may want to check into programs like stegdetect etc that could determine if something is in the file but then you have to figure out how to extract that from the file and usually they contain passphrases and further obfuscation etc.

More details would be required on precisely what you're trying to accomplish.

I have a gut feeling that certain social media bot nets use information hidden in images, videos, etc to flag those files and any posts with them in it for action. Like an internet equivalent of a streak of chalk on a mailbox to signal a dead drop.

I want to be able to take a batch of files and look for any strings of data they have in common.

You need a definition (your desired definition) of "similarity"

You mean image patterns ? (also considering colors or not) ?

You mean exact sequence of bytes ?

There are two major technologies

  • neural net, you train the net to "recognize" patterns, this is fuzzy matching
  • byte comparison, this is exact matching, quite slow, clearly.

See I'm not even sure where to begin. I'm not even sure how they can be doing it, I know there are bot nets that governments and corporations use to push their agendas. My gut feeling is that in images they share or profile pictures or whatever there are embedded ways they can recognize each other and let their fellow bots know what to do. For example upvote this, downvote this, share this, respond with this canned response, etc.

If this is true it would be outstanding if a person could crack it and turn it to their own purpose.

I see, it is neural-net

Google has their own version of the same old tech (neural-net was so old style name)

https://www.tensorflow.org/

Have a look at the tutorial and the examples on "classification"
