Research Unveils Improved Method To Let Computers Know You Are Human

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."

You you just wait. They'll start putting advertisements in the captchas.

So that's why my last one said "be sure to drink your ovaltine."

I'd rather they continue to think I'm a bot!

Proving I'm human just subjects me to more ads I don't want to see.

Solve this puzzle for him.
