The patents in lot 92 relate to innovation for verifying human users through cognitive processes. Visual patterns and tests are used to distinguish between human users and computers through exploiting the fundamental differences between computer-based vision and human visual processing. The patents also teach preventing the outsourcing of cracking captchas through detecting language and/or cultural fluency. Further disclosed mechanisms prevent human validation requirements from interrupting workflow, in one aspect by providing the ability to keep a Captcha response updated between user tasks.
