NotOneBit.com Killbot with Audio
Welcome to KillBot with Audio. This script is intended to eliminate various types of web based robots from repeatedly filling out forms by requiring the visitor to enter some simple data (called a Turing or CAPTCHA test). Many times you may have a form (feedback, poll, guestbook, etc.) on your web site and a malicious user targets a script to automatically fill out your form until it either cripples your server, skews statistics, or floods your inbox. By requiring the visitor to read the text in an image (over 900,000,000 possible combinations) and enter that with the other data in your form, you can prevent automated scripts from repeatedly filling out your form.
KillBot with Audio improves upon our popular KillBot application by adding an audio cue that will play the code you see on screen. If you are unable to read the visual cue, now you can listen to the cue and enter the code. Having an audio cue further ensures that all your visitors will be able to pass this simple authentication test. For convenience and compatibility, KillBot with Audio presents the audio cue in Flash format. Now your visitors that have difficulty reading a scrambled code, can simply listen to it, making your forms compliant with the Americans with Disabilities Act. KillBot can be set to be case-sensitive or case-insensitive, or it can be set to display only uppercase or only lowercase.
KillBot with Audio can play the audio cue using any language and can also differentiate between uppercase and lowercase text.
Please test out the sample form below for yourself and see! If you find the image too difficult to read, simply click on the image to reload the page for a new one, or listen to the audio cue. Looking for an industrial strength solution? Check out KillBot Pro!
