Proton, the Swiss-based company renowned for its commitment to privacy-focused online services, has unveiled its  CAPTCHA service. CAPTCHAs are familiar challenges on the web that distinguish between human users and bots. The company’s decision to create this proprietary solution stems from a desire to maintain its high privacy, usability, and security standards.

Proton’s team leader for machine learning, Eamonn Maguire, wrote in a blog post about the company’s goal to create their own CAPTCHA service. Specifically, they aimed to develop a CAPTCHA system that guarantees user privacy and a smooth experience. As a result, the outcome is a CAPTCHA solution that provides excellent defense against bots while upholding user privacy. Moreover, Proton CAPTCHA is the world’s initial CAPTCHA with pre-installed censorship-resistant technologies.
