hCaptcha is a CAPTCHA service developed by Intuition Machines, Inc. that is used by Cloudflare on over 25 million websites.

About

hCaptcha is a 'leading recognized service that provides unique CAPTCHA challenges to help detect whether the user of a website or app is human or a robot. Filling out a hCaptcha is similar to filling out a reCAPTCHA. The program asks the user to prove they are human by asking the user to select all images matching a generated query, called a label, stored in the datasets that hCaptcha uses. If a user enters an hCaptcha successfully, the owner of the website hosting the CAPTCHA gets paid in consumer credit.[1] The 'h' in "hCaptcha" stands for "human", and the service tracks exchanges of value using the Ethereum blockchain.[2] hCaptcha earns revenue by selling its annotation services to third party companies.

Background

===hCaptcha was created by Eli-Shaoul Khedouri and his team in San Francisco. He founded Intuition Machines, Inc. in 2017. Early development of products at Intuition Machines required large quantities of human annotation, which caused Khedouri to hire workers in Vietnam to match images to labels and to build the dataset. The hiring of these workers was not easy to scale up or down quickly. Khedouri switched to using Captcha Farmers. Captcha Farmers are people who get paid a fraction of a cent to solve a CAPTCHA. According to ZDnet, these workers may receive as little as US$2 an hour.[3] Realizing that Google was extracting many billions of annotations per month from its reCAPTCHA service without paying anyone, he decided to create an alternative that shared the value captured with the websites using his hCaptcha service.

hCaptcha was designed to run using his HUMAN Protocol to secure the exchange of value via the Ethereum blockchain. In 2019, Fastcompany reported that ~10 million users were interacting with hCaptcha each month and that global technology companies used hCaptcha to build datasets.[2]. In 2020, The Register reported that hCaptcha was serving more than one billion requests per month[4] before its adoption by Cloudflare on over 25 million[5] websites.===

Adoption

It was announced on April 8, 2020[6] by Cloudflare as the company's official CAPTCHA service. Cloudflare moved to hCaptcha over Google's reCAPTCHA service due to privacy and sustainability concerns regarding Google's collection of data and, more recently, the company charging for the service.[7][8] According to Cloudflare, staying with reCAPTCHA "would have added millions of dollars in annual costs just to continue to use reCAPTCHA for our free users". hCaptcha is said to collect less user information than Google's reCAPTCHA. It also works in countries like China where Google services are blocked by the great firewall.[9][10][11]

Privacy Pass

hCaptcha is currently the only CAPTCHA service to support Privacy Pass, an emerging standard for preserving user privacy that is currently being developed through a working group at the IETF.[12] This works via an open source browser extension[13] that provides users with the ability to create and sign cryptographically blind tokens for websites that support the Privacy Pass protocol. The extension generates passes containing cryptographically blinded tokens that are signed by hCaptcha once a challenge is solved. When the user visits another site using hCaptcha and needs to pass a challenge, they are redeemed automatically. The blinding procedure means that signed and redeemed tokens are cryptographically unlinkable from hCaptcha's perspective, and thus user privacy is preserved.[14]

HUMAN Protocol

The HUMAN protocol is what hCaptcha's service runs on. The HUMAN protocol's job is to make sure that all information stored in hCaptcha's dataset is accurate, that websites are compensated based on the accuracy of the answers, and that requesters of annotation do not pay for inaccurate results.[15] The Protocol is responsible for paying website owners in its store credit (called "HUMAN Tokens") when the site's clients successfully solve a hCaptcha challenge.[16]
