Publisher review:MSCABImage is the best protection from posting bots (robots). MSCABImage is the best protection from posting bots (robots).
These bots create hundreds of email accounts on your web-based mail servers and spam from there, fill your forums with thousands of commercial postings and screw your online polls. How it works
ABImage Component generates random number and converts it to image file. Your Web Application asks visitor to read the number and type it in a textbox.
Human can easily recognize the number, but there is no way how bot can do this. As soon as the form will be posted back, application compares the random number with the number posted by visitor and authorizes the human or rejects the bot. The number can be generated by internal random number generator or can be set by the application. Image can be extra protected from recognition by adding random noise.
