GAPTCHA: A Game-Based Image-CAPTCHA
摘要
The threat of bot attacks has increased with the abundance of a diverse range of smart devices used globally. Users access the Internet for various needs, such as entertainment, education, e-commerce, and data exchange. It has tremendously increased the number of users and connected devices. The completely automated public Turing test to tell the computer and human apart (CAPTCHA) is a fully automated Turing test to differentiate a machine from a person and safeguard Internet services from spam and bot assaults. However, the distortion levels make human identification unpleasant and impossible. This paper proposes a novel CAPTCHA, named “GAPTCHA,” based on a famous game called Snakes and Ladders game. It uses a simple keyboard, mouse, and touch inputs. The results showed that 3% of the people got it wrong, and about reusing the proposed GAPTCHA, 100% of the users said yes, which is a positive result for its successful user experience.
