'Humans Not Invited' Is a CAPTCHA Test That Welcomes Bots, Filters Out Humans (vice.com) 82

While most CAPTCHA tests we come across on the Web are usually meant to keep robots out, one website is welcoming them in. From a report: The conceit of Humans Not Invited is essentially a reverse CAPTCHA. Visitors to the site are greeted with a vision test not unlike the ones you've done before, but instead it's filled with seemingly indistinguishable blue and gray blurry boxes. When I tried, prompted to "select all squares with selfie sticks." Most humans, like me, will fail to decipher the hidden selfie sticks and will be shown a message that says "YOU'RE A HUMAN. YOU'RE NOT INVITED." To the human eye these boxes appear indistinguishable, a specially programmed bot can spot out the correct image simply by identifying a handful of pixels, according to the project's creator, Damjanski, (his real name is Danjan Pita).

      I've heard that Tinder already uses this technology to populate the female profiles.

      • by Rande ( 255599 )

        It's been used to populate dating sites since they were created. There's always more horny guys than there are good looking women. Horny guys pay for dating sites, so the sites make sure there's lots of (fake) female profiles, even getting employees to interact with them to make sure the guys think they still have a chance at love and keep paying.

      I guess the big difference is that we humans can employ an AI program to help us beat the reverse captcha, but the AI can't (yet) employ humans to help them beat the captcha.

      Unless you see captcha's as a method for the AI to employ humans to help it beat the captcha, of course. And it wouldn't surprise me if there were sites that place a bot-encountered captcha in their human interactions in real time as a way of dealing with them?

    Off hand I'd think it wouldn't be too hard to define a bot only captcha. That harder part is whether the bot knows it's only for them.

    Awhile back I launched a social web site with TOU that only trolls were permitted; serious folks not welcome.

    This is also why we can't detect signals from alien intelligences. They don't care to contact meatbags, they're waiting for earthly intelligence worth communicating with.

  • Saw the article here and tried it twice before I showed it to a buddy in my office. He passed the captcha on his first try... THEY'RE AMONG US
    • I have that feeling with every CAPTCHA. They're becoming so difficult I need a bot to resolve them.

  • Am I the only one who got a CAPTCHA where the bots should identify dicks? Brings a whole new meaning to gender binary.
    • by Anonymous Coward

      Also got this on my second try. Laughed for a good ten seconds.

      Now I'm wondering about the social implications of using captchas to not only filter out robots, but filter out specific human demographics.

      If slashdot plastered dickpics on a captcha it would probably cut down immensely on people posting from work :)

      • Don't know why you've been down-voted, but good to know I'm not the only one who got that CAPTCHA. Was also not trying to be rude or funny when I wrote "dicks" instead of penises or something more work appropriate. It literally asks to identify dicks :)

    I think the take away from this is that it shows that AI isn't really seeing what we think it's seeing in most cases. Any human would say "there is no selfie stick" or "there is no traffic light", but for some reason the AI sees something where nothing exists, similar to how humans sometimes see a face where no face exists.

    Anecdote time/a>. There was an AI that was supposed to be learning to tell wolves from other dogs. They eventually thought the AI learned pretty well and thought it was doing a great job. On all their test photos, the AI was doing a great job in determining "wolf" or "domestic dog". However, they learned later that the AI was just actually seeing if there was show in the picture, as all the pictures of wolves contained snow, while the pictures of other dogs didn't contain snow.

    • And your comment just made me realize that this can be weaponized. Just toss one of these in every one designed for humans, and if they pick that one, they're a bot. Humans won't likely pick it, as demonstrated here.

  • welcomes bots while leaving normal, decent people totally unaffected.

  • Couldn't we use simpler test that are easier to solve with computers?
    Such as "which of these 100 numbers of 1000 digits are prime?", you have 5 seconds to answer.

    No human can ever beat this so you'd have to use some automated tool. Why weird computer vision task?

    I should have absolutely no trouble at all being invited into the brotherhood of bots. I frequently spend 4 or 5 minutes trying to prove that I'm a human, and I don't always succeed.

    The folks at Google who infected the Web with reCaptcha should DIAF.

    The definitive test for robot-hood was created over a decade ago. [youtube.com]

    Which of the following would you most prefer:

    A. A puppy*
    B. A pretty flower from your sweetie
    C. A large, properly formatted data file

    CHOOSE!

    * It is the bad kind of puppy - not mechanical in any way

  • Make an image that's all one color. Say #FFFFFF (white). Then set some of the pixels to #FFFFFE. A machine will instantaneously be able to tell the difference. The human eye won't. Why do you need anything more complicated than that?

  • Send them to a 3rd world country for cheap... :P deathbycaptcha.com
  • In the movie Blade Runner (and even in Philip K. Dick's novel "Do Androids Dream of Electric Sheep?" from 1968 on which the film is based on) there is an elaborate test to distinguish humans from androids, which is called a Voight-Kampff-Test (conducted with a Voight-Kampff device).
    This is exactly what a captcha does - distinguishing humans from non-humans. Therefore shouldn't we rename captchas to "Voight-Kampff-Tests", because that name is clearly older and therefore the original (and it's a cool name)?
    • by ghoul ( 157158 )

      The Voight-Kampff Test is used to capture non humans. Capture->Captcha->re Captcha. The name already pays homage

      I'd prefer it be written as VK-tests (otherwise I can't spell it!) but otherwise support this.
