Hi, It wouldn't work for a high traffic, popular site because it would be easily broken. A low traffic or less popular site probably wouldn't need any kind of CAPTCHA system. Has anyone investigated the possibilities of decentralised identity management systems such as OpenID? The idea is that you can have just one identity (username and password) roughly speaking, and service providers delegate to your identity management service for verification. So, for example, if Google were an identity management service, you could use your Gmail address for every service that required registration. I don't think it would completely eliminitate CAPTCHAs, but it could make life easier. --Jim ----- Original Message ----- From: Claude Saulnier <claude.saulnier@xxxxxxxxxxxx> To: <vicsireland@xxxxxxxxxxxxx> Sent: Thursday, June 26, 2008 11:11 AM Subject: [vicsireland] Re: research on audio CAPTCHA > Hi > > On the Captcha matter, we are doing some research ourselves. > > In order to avoid captcha and the audio, and the complexity and so on, we > were thinking of using a question such as what is 2 + 3 and you then need to > enter the result to validate the form.
