I gave a talk at A New HOPE on the privacy and security of hCaptcha, a commercial captcha product. This talk was officially called “hCaptcha: Profits over People and Fscking Useless”. Due to new information I got after the deadline for changes, the talk I actually gave I titled “Is the CAPTCHA dead?”.
The slides, relevant video, FAQs and other materials are online on a dedicated page.
