Possible use cases are services, with which Bots can manipulate or abuse the service, as for instance on-line inquiries, guest books, registering E-Mail addresses (by those Spam can to be sent) or log in entrances.
The now available captcha service "YourCaptcha" is one these picture-based CAPTCHAs. It is characterised by an easy integration with the help of a simple <IMG SRC='...'> HTML tag on the own Website. The correct character input is checked over a simple ASP.NET Webservice.
Additional feature list:
- The use of different character fonts
- Rotation and deformation of the individual characters
- Overlapping random pattern
et cetera ...
