Research Unveils Improved Method To Let Computers Know You Are Human

Posted by Unknown on from the until-computers-improve dept.

An anonymous reader writes CAPTCHA services that require users to recognize and type in static distorted characters may be a method of the past, according to studies published by researchers at the University of Alabama at Birmingham. Researchers focused on a broad form of gamelike CAPTCHAs, called dynamic cognitive game, or DCG, CAPTCHAs, which challenge the user to perform a gamelike cognitive task interacting with a series of dynamic images. For example, in a "ship parking" DCG challenge, the user is required to identify the boat from a set of moving objects and drag-and-drop it to the available "dock" location. The puzzle is easy for the human user to solve, but may be difficult for a computer program to figure out. The game-like nature may make the process more engaging for the user compared to conventional text-based CAPTCHAs. There are a couple research papers available: "A Three-Way Investigation of a Game-CAPTCHA: Automated Attacks, Relay Attacks and Usability" and "Dynamic Cognitive Game CAPTCHA Usability and Detection of Streaming-Based Farming."

    1) Bad eyesight is a real thing, like any disability, and you don't have to be old to suffer from it. Some people find captchas simply impossible to read, no matter how bright they are;

    2) Captchas are merely evidence that techies are not smart enough to think of any way to solve a problem but by burdening the user. I suppose it goes with the territory that they'd also blame the user who doesn't like them. "It's your problem now and it's your fault if you don't like it!" - great pride in your work there, chump;

    3) A homeowners' association is one of those things that contributes Community and ultimately Society, both of which which Reagan tried to pretend didn't exist. A generation or two later, and we have one dying empire and world laughing stock. Well played, idiots!

    4) When you criticised voting, you lost entirely.

    I'm in my early 30s, so I'm far from Baby Boomer, but I'm not an ignorant, ungrateful little shit either.
