Pure Flash Captcha
Captcha in flash
Well not to say much but as we all know for ages we have depended on image verification systems called captchas. There have ben many variations of it over the years. Some have even come up with audio based captcha and picture identification captchas.
So i thought why not flash captcha ? why flash ? simply because i love it and it will be a unique distinction.
flash cannot be crawled. so taking advantage of that i thought why not design a captcha in flash as no program can use OCR on it.
Also using dynamic font embedding feature in actionscript 3.0 makes this a ideal project. you can view more info on AS 3.0 dynamic font embedding here.
You can put fonts in swfs and supply it from a folder on your server. The biggest advantage is that it can be used even by people who dont know PHP or have php involved in their projetcs. FlashCaptcha works even on static html pages.
Currently i have pushed ina plugin system where you can have dynamic obstructions over the captcha with actionscript. I can work more on it depending on what more is needed of it.
Though limitations also exist. We should be optimistic.. right ??
The example in the zip includes Javascript integration sample to help you integrate it in your web page.
So try it out and let me know how you like it and issues of course
