I'm sure this isn't done, but I do have to wonder if it'd be possible to identify a user by their unique behaviors when interacting with the extended Recaptcha puzzles. Something like writing style analysis, but applied to patterns of mouse movement, click timings and positions, or recognition rates for particular types of problems.
- jamiek88 8y agoIf it can be done it will be done seems to be the moral of these stories so lets hope not.
- justwalt 8y agoWith a large enough dataset, I bet you totally could. But if someone were completely anonymous, it might require too many inputs for it to be practical in a one off situation. I’d guess you could identify someone with enough time after they got a new computer.
