BotDetect CAPTCHA - Features

With the exponential growth of services and businesses over the Internet, online security has become a real concern for software developers, architects, managers, and vendors.

Software programs are written to impersonate human beings, mimic their surfing patterns, and imitate online activities for various malicious purposes. These "pretending to be human" programs are referred to as spam robots or spambots.

Lanapsoft BotDetect CAPTCHA is an efficient out-of-the-box security solution designed to deal with this threat.

Features in Version 2.0

Audio CAPTCHA Support

• Besides CAPTCHA images, BotDetect 2.0 can now also generate CAPTCHA sound files for increased accessibility, thus making registration easier for the colorblind and people with otherwise impaired vision.
• The sound file containing a spoken recording of the random CAPTCHA code can be accessed by clicking the speaker icon to the right of the usual CAPTCHA image.
• When a user clicks the speaker icon, a CAPTCHA sound file is generated on the server and sent to the client without refreshing the page.

50 CAPTCHA Rendering Algorithms

• No single rendering algorithm is ever 100% unbreakable - but using multiple CAPTCHA algorithms can stop even the most determined attackers.

Improved Security and Scalability

• Since ASP.NET ViewState is no longer used to persist any information at all, BotDetect 2.0 ASP.NET CAPTCHA is now 100% safe from client-side ViewState tampering, resending, etc. This change is related to a previously reported issue.
• The workflow used to generate random CAPTCHA codes, images and sound files has been improved for maximum resource conservation, ensuring that even the most traffic-heavy sites can benefit from CAPTCHA protection without notable performance impact.
