Visual Captcha[edit]

What about visual Captcha, where the human operator has to distinguish the shape? ("check all squares with cars"). Also, Stanisław Lem mentioned captcha in his books in the 1960s (! - a hint: it was employed in an elevator, with a chatbot). Zezen (talk) 06:35, 17 July 2017 (UTC)

Got a citation or a book name and page number for the Stanisław Lem claim? --Guy Macon (talk) 18:46, 5 November 2017 (UTC)

Relecteur VS2I[edit]

Hello, I'm Omar Mehrez and I'll be reviewing your article in the context of a project of my masters degree (VS2I).

First, I find the article quite detailled and well written. My comments are more about the form.

  • Form


      History

---> You can replace the "Such that a filter ..." with " So that the filter ..."

      Circumvention
           Machine Learning-based attacks

I don't quite understand the sentence : "As a result, there were many instances in which CAPTCHAs were of a fixed length and therefore automated tasks could be constructed to successfully make educated guesses about where segmentation should take place." ---> I guess it's a bit hard to get because it does not contain separators, such as ',' or '.'...

What do you mean by "which made the test much easier to game." ---> Do you mean "wich made the test much easier to solve." ?

What do you mean by "algorithms were created that were successfully able to complete the task..." --> Do you mean : "algorithms were created to successfully complete the task"? Or "Algorithm that were created completed successfully the task..."


  • Context


I Hope you can Develop further the "Relation to AI" Paragraph"; maybe adding details about the Use of Captcha solving to train AI.

Do you have references for the alternative method "MAPTCHAs" ?
