Have you tried to complete a form on a website and were asked to enter what you see on a distorted image of crazy letters or numbers? It can be frustrating especially if the letters are scrambled or right next to one another. However, these letters validate that you are a real human person completing the form and not an automated computer program.
The technical term for the distorted image is CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart). CAPTCHA can be used in various places on websites such as registration forms or blogs. The primary goal of CAPTCHA is to prevent spam that is generated by automated computer programs that attempt to complete forms or leave comments on a blog. It may seem like a hassle to be asked to enter in the letters you see on a distorted image, but it greatly reduces the amount of spam that a website owner is faced with. CAPTCHA is used on websites such as Google and Yahoo because they too want to reduce spam and the headaches it can cause.
If you receive spam through your website and are interested in reducing this, talk to the team at Vivid Image. We can help you integrate CAPTCHA into your website and help you receive the leads you need instead of the spam.
