HIPUU: a Universally Usable Approach to Defeating Automated Bots

There is clearly a need on the web for security features to stop spam and bots. However, many security features on web sites are not accessible for people with disabilities. A common form of security on web sites is a human interaction proof. HIPs are used to differentiate between humans and automated bots. The most common form of HIP is known as a CAPTCHA (Completely Automated Public Turing tests to tell Computers and Humans Apart), but visual CAPTCHAs are inaccessible, and existing audio CAPTCHAs are very hard to use. We have created an alternative form of human interaction proof, which is both secure and accessible. This presentation will give an overview of the HIPUU concept and evaluation testing.
