How to prevent BOT Attacks in Form

Hi Team,

I have a requirement to add captcha in my form to prevent bot attacks.

My Initial thought is to include Google Recaptcha but later I came to know like google API will not work in China.Since our majority of the client business is from china.I could not leverage google captcha.

Is there any alternative options available.Please let me know your thoughts.

Thanks,

Sambasivaraja.

    Hi Sambasivaraja

    We are also working on defining a solution for Bot attacks on forms, here is what we are doing:

    1. Honeypot technique: http://jennamolby.com/how-to-prevent-form-spam-by-using-the-honeypot-technique/

    2. CSRF: The CSRF Protection Framework  (but this doesn't work for anonymous users and hence it is of no use to us)

    There are other ways to implement captcha too but Google's Recaptcha is the best bet.

    Hi Sambasivaraja,

    You might need to host server near to china instead of china and use mod proxy to redirect to google Or use different service provided.
