Secure from All Angles

 

Traditional CAPTCHA is a binary test: if you present the right answer, you’re let in. Not so with PlayThru. Our security system requires multiple levels of user interaction before a site visitor is verified as human. And finishing the game isn’t enough: PlayThru actually analyzes how visitors play each game, modeling their behavior against our proprietary humanness algorithm. Even bots that complete the game are stopped.

 

Front-end

Natural Language Processing
We require more than just deciphering text and repeating it back: to complete a PlayThru, you have to comprehend the meaning of the instructions.

Image Tracking
Our games aren’t images that can be easily copied and processed by machines, or even by humans in a country with low labor costs. The dynamics of the game change constantly. If you’re a bot, that means you have to perform image segmentation, recognition, and tracking.

Variety
We keep the bots guessing by constantly releasing more games, incorporating an ever-changing library of images and scenarios that frustrate their efforts.

Back-end

Machine Learning
We analyze various facets of a user’s interaction with the game and run them through our machine learning algorithms to determine how “human-like” they are. Completing the game isn’t enough: you have to play like a human does.

Customization
Text-based CAPTCHAs can’t be made more difficult for bots without becoming more difficult for humans, too. With PlayThru, you can decide how strict or lenient you want the back-end scoring to be—without making the game any more difficult for users.
