CAPTCHA Code Sample.abst

In order to prevent non humans from filling in forms one tries to generate something that can only be read by the human eye. The user needs to enter something he/she sees within a graphical representation. It needs to be something subjective, since the interpretation of butterflies would generate more discussion and confusion than needed. This PHP class code enables the inclusion of CAPTCHA technology within SAP Web AS BSP applications. Detailed information on implementation is covered in the SDN blog, "Die Mensch Machine"
