If you are running any web pages, some times you wish to give the contact Email ID to the readers. Some automatic Email tracking application easily get your Email IDs and send some spam mails to your inbox. How can we resolve this problem.

Some web sites, they put there Email IDs in the image format. So the Email Tracking applications fail to find those Email ids, because they don't use the proper OCR processing to find out from the images. Another way is using reCAPTCHA.

What is reCAPTCHA? It is a free CAPTCHA service, and reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly.
