    Lightbulb Secret Tags - An alternative to Captchas?

    For a website where users can enter content, register and comment, I needed a system to hold bots at bay regarding registration and commenting. I did not want to use captchas, because by using captchas a website discriminates the legitimate user, making her justify herself again and again -- and because of accessability.

    So I created a system called Secret Tags.

    This is a rather lengthy text, so please forgive me for pointing to it instead of posting it here.

    Any comments greatly welcome, whether here or there or via PM.

    That's an interesting read. While I'm not an expert on the abilities of bots, seems like it could be a helpful solution to the problem.

    Even if there are some potential problems with it, it definitely shows the need for a fix. The existing implementations just aren't accessible to those who can't see the image, or can't see it well.

    Thanks

    The existing implementations just aren't accessible to those who can't see the image, or can't see it well.
    Actually the used challenge-response systems are not accessible enough. Whether you look at captchas using characters in pictures, or several images a user has to choose a keyword to, or funny question the user has to answer, it takes the user too much work to get going. I am with Steve Krug here, keep it simple, stupid.

    Then again, captchas were not invented for their current usage - they are a system to tell a machine from a human, or vice versa. They were simply not designed for web applications.

    Here's an update. Secret Tags do work, quite well to be straight forward. 40% of all spamming attempts were blocked because the did not carry the secret tag with them.
