Google reCAPTCHA API Solves Identity Verification Puzzle

Google has announced a new reCAPTCHA API that eliminates the need to solve distorted text CAPTCHAs that have long added security against robots. Google’s recent research indicated that modern artificial technology can decode distorted text challenges with greater than 99% accuracy. The new reCAPTCHA technology considers a user’s entire engagement with the CAPTCHA — before, during and after — to decide whether the user is a human or a robot.


The new technology, implemented via the reCAPTCHA API, continues to utilize a question-and-answer methodology; however, the user simply clicks “I’m not a robot” instead of physically typing out the solution to a challenge. Google’s back end evaluates the entire experience and determines whether the user is a robot or a human. In the event that the risk analysis engine cannot adequately predict whether the user is a human or a robot, a traditional CAPTCHA will appear to add an extra layer of security.

Not only does the new API cut down on the workload of a Web user, the reCAPTCHA API is more mobile friendly. Using a mobile keypad to type distorted text is a hassle. However, the reCAPTCHA API allows users to solve simple image selection problems with the tap of an image. See the below image for an example of reCAPTHA implemented in a mobile environment.

Early adopters of the new technology include Snapchat, WordPress and Humble Bundle. In the past week, more than 60% of WordPress traffic passed through the new API with a No CAPTCHA experience. Humble Bundle’s No CAPTCHA traffic surpassed 80%. To learn more or to integrate the reCAPTCHA API with your website, visit the reCAPTCHA site.
