SPAM Form Processing / CAPTCHA Support
Stands for - Completely Automated Turing Test To Tell Computers and Humans Apart
Visual Form Submission SPAM Protection
Over the past while there has been a noticeable increase in automatic form submissions with junk details over the internet.
OSD have developed a process, which you may have seen on other sites, making it more difficult for these automatic submissions, by means of embedding text characters on an image.
However, some malicious scripts are even able to take the image and process it for the embedded characters, so it is not as simple as just putting an image up with a few characters on it. The goal is for it to be too hard for a script to process the characters but not too hard for a human to read.
OSD CAPTCHA support uses a configured list of various font types and randomly picks a configured number from all configured types and then dynamically adjusts the size, density, colour and spacing of the characters. The background image can also be configured and customised to match your website.
An example can be seen below:
