Human Intelligence Identification

The Human Intelligence Identification Script looks for the Human Intelligence Identification Answer provided in a form submission. If the Answer is not correct the form will not be processed. This effectively prevents forms submitted by automated robot (bot) scripts from being processed. It blocks automated form span and can also decrease the risk of form hijacking.

The concept underlying the Human Intelligence Identification Script is similar to the that used in Captcha. Captcha is the application of distorted text images that are difficult for bots to decipher. It is extensively used as a human verification test in web form submissions to block automated form submissions by bots. Human Intelligence Identification possesses the advantages of Captcha but is much simpler to implement, cannot be bypassed using OCR (optical character recognition) and is more user friendly, with less accessibility issues. Human Intelligence Identification is an easy to implement, easy to use, and effective alternative to Captcha.

Human Intelligence Identification is included in form1 web form code. If a form is submitted without the correct Human Intelligence Identification Answer a Hii required message is displayed.

The Question and Answer used can be pretty much anything you like but it should be simple and clear. A human should never get it wrong. For example:

One of the strengths of Human Intelligence Identification is that the Question can be freely set by the form developer. This makes it very difficult for bot developers to identify a question pattern and related answer that can be programmed into the bot.

The question can be generic, related directly to your site or type of visitor, a common joke, a fill in the blank, some text on your page, java script prompt text, a select dropdown list, radio buttons or even a password (if you want to limit form submissions even for some real users).

You can see the script in action and give it a test at form1 Example.
