A CAPTCHA alternative that asks users to identify photos without specific objects, improving accessibility and user experience.
Negative Captcha is an alternative to traditional CAPTCHAs that presents users with photos of everyday objects and asks them to identify images that do not contain a specific object, rather than solving a visual puzzle. For example, it might show images of cats, dogs, and birds and ask you to identify the images without birds.
It works by leveraging human abilities to easily recognize objects in images, rather than testing users' ability to decipher distorted text or solve visual puzzles. This improves the user experience, as most people find selecting images more intuitive than solving CAPTCHAs.
In addition, because Negative Captcha does not require deciphering text or letters, it is more accessible to users with visual impairments or learning disabilities. The images used are also pulled randomly from an expanding set, making it difficult for bots to solve.
Overall, Negative Captcha aims to offer a CAPTCHA alternative that has better usability, accessibility and user experience while still effectively blocking automated bots and spam.
