Metadata: An Invisible CAPTCHA

  "Pramana, which means "proof of reality" in Hindi, is currently in "stealth" mode, and won't reveal much about its customers or just how it works. The company isn't just media-shy--it also wants to prevent bot creators from figuring out how to evade its analysis." Sounds like security via obscurity to me.

    But they are not trying for security - but rather profiling, so clichés that apply to security don't apply here. But I don't think it will work anyway. For example, you might want to check the page to page timing - but I tend to middle click a whole bunch of pages, and then read each tab and close it.
