  1. Hi has anyone got any ideas about putting a captcha solution inside a
    standard web page?
    Thanks,
    Alistair.

    B says they suck so I don't know if you should.... look up the
    threads on this at this newsgroup (go to google groups and type
    in alt.html, then when there, type in "captcha")

    Also note the recent news about spammers' tools that penetrate through
    captchas.

    Of course, a "standard web page" does not need the protection that captchas
    are supposed to give. A _service_ (such as free e-mail service) might need,
    but captchas are a wrong approach anyway, and illegal in civilized
    countries, since they discriminate against various minorities (typically
    including the blind).

    As usual, it would have been best to start with stating the _problem_ that
    captcha was meant to solve.

    I like this one that was developed as a WordPress plugin, but you should
    be able to adapt it for more general use.
    http://sw-guide.de/wordpress/plugins/math-comment-spam-protection/

    It does require server-side scripting, of course.

    A captcha is synonomous with a bloody pain in the arse.

    Compared with the usual discrimination of the blind and nauseating trouble
    to other people, that method discriminates against arithmetically challenged
    people and causes nauseating trouble to other people. Why should I do some
    math exercise just to prove myself human? And the idea postulates that
    people who cannot compute 9+9 (I have actually seen such people working in
    shops, buses etc.) are not human - so they can presumably be eliminated
    without any moral objection past those against killing some insects or rats.
    Oh, was I somewhat provocative? But please blame the original provocation,
    captchas, not me.

    I'd suggest reading the CAPTCHA article at w3.org before considering any new
    ways to create problems with captchas.

    In any case a math exercise is a particularly bad test for
    distinguishing between a human and a bot. A script could easily be
    written to parse the sum, calculate the answer and submit it.

    A script can be written to parse pretty much anything.

    I wouldn't suggest using the math problem for a site with heavy traffic,
    but it can serve a small site. Depends on the type of site and target
    audience whether it makes sense to use such a scheme in the first place.

    http://www.w3.org/TR/turingtest/#conclusion
    "It is strongly recommended that smaller sites adopt spam filtering
    and/or heuristic checks in place of CAPTCHA."

    I do my own heuristic checks now, but they can be a real PITA to maintain.

    One of the objections against captchas is that they are often too
    hard to read. The easier to read, the easier for a robot to do so
    too. But to read and understand is the toe hold. I would be very
    surprised if we could not construct a question that anyone who
    could understand English would be able to answer easily but any
    present generation robots would fail.

    Two ends!!! Ain't seen you in an iguana's age, little buddy (-medium
    buddy? -big buddy?) How's life been (mis)treating ya? So, guess you _are_
    that old. Curious you made your reappearance on Friday the 13th...

    Me, myself, and I are doin' all right. Oh, been having trouble with the
    broads again, -so what else is new? When one is in unequal company,
    there's bound to be some unbalance on the downside. Lately, though, I"ve
    become more cautious of them vagrant varments of the vamplands ya run
    across every now 'n then, but whenever my guard slips down I find I can
    still get it up again.

    Welp, nice seeing you, ol' horse. Been drinkin' gallons of coffee so I
    gotta go and agitate the anaconda. As I say to my girlfriend, don't take
    any wooden pickles, and hasta luego.

    Been spending way to much time doing nothing but watching the nursie girls
    fussing about but old people do that a lot, watch that is. Don't worry,
    your days commin soon.

    Hehe, yeah, you've got that right. 'Course nursie-watching ain't such a
    bad pastime if they're wearing them short, little skirts with the
    translucent material and bend over alot.

    Better watch out, Pete. Things like those can swallow ya and turn you into
    Yorkshire pudding.
