CAPTCHA Form Security

Callsave uses CAPTCHA code on its forms.

c.a.p.t.c.h.a. = completely automated public Turing test to tell computers and humans apart.

In other words, captcha is used to protect web forms against spammers. Captcha can be a great help in reducing form spamming.

Captcha uses text or image recognition to validate a form and prevent spammers using internet 'bots' to use web forms improperly. Internet robots ('bots'),are programs made to scour the web for forms and e-mail addresses. Sometimes the image contains text that is distorted, to confuse bots that employ image recognition techniques.

Our eyes are much more sophisticated than bots, recognising complex images and able to extract the numbers and letters which are in the image. The bot on the other hand, does not have such sophistication, and mostly is programmed to extract e-mail addresses from the html code of a web page.

When you encounter a captcha page and see a code generated image - usually numbers and letters - you must insert this code, by typing the same numbers or letters in the image into a field and if you have copied correctly - you will be allowed to click the send button and send the form. This basically means that a human can pass through a captcha protected form but a bot will have a harder task.

This method of protection, whilst not perfect, is usually sufficient for websites where there is little commercial value in the collected data from the forms.

However, to ensure absolute data security, Callsave employs SSL technology on it's websites. For further information on this, please refer to our Site Security Statement.
