Wanted to apply captcha for this page Surplaplace . So i generate a random string n apply it on image & compare the string with entered text but my Sr. Nishant told that it can break by image processing techniques & he suggest that go for recaptcha which is very secure n simple to use.
Its amazing guys API provided by google. Just log on Here register with ur google acc. & site name after that it generates a public n private key that we have to use in our coding.
MailHide
It's not good to write your email address on the web page because anyone can use it use it the way you don't want. To avoid spam email's should use mail hide functionality. In short it hides some words from ur email id & view email id one should write correct captch. MailHide is also a good service.
