MSCABImage for Linux
-
Version
1.2
MSCABImage is the best cure from nasty posting bots
(robots). These bots create hundreds email accounts on
your web-based mail servers and spam from them, fill
your forums with thousands of commercial postings and
screw your online polls.
How it works. ABImage Component generates random
number and make a hard-to-recognize picture from it.
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 a bot can do that.
As soon as the form will be posted back, application
compare the random number with the number posted by
visitor and authorize a human or reject a 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 with
adding random noise.
