MSCABImage for Linux 2.0
MSCABImage for Linux - 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.
