What is BotDetect?

BotDetect is a kind of test that can reliably determine if the solver is human -- allowing webmasters to tell bots and humans apart.

BotDetect automatically generates and grade tests that:

  • Most people (i.e. real human users) can easily pass
  • Current bots (i.e. various computer programs) can't pass

Bots are the Problem and BotDetect is the Solution

With the exponential growth of online services and businesses, website security has become a serious concern for webmasters and web application developers.

The Problem: Bots

Many software programs are written and used to impersonate human beings, mimic their surfing patterns, and imitate their online activities for various malicious purposes. These "pretending to be human" programs are referred to as bots (short for "robots"), spambots or spam bots (since they are most commonly used for spamming).

The Solution: BotDetect

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

Using test images specifically designed to be out of the reach of currently available computer vision and OCR technologies, bots can be prevented from accessing protected website functionality.

While computer programs cannot read the textual code from the image, it is easy to read for most humans. So the answer to the webmaster's question "is the current client submitting this page a real person, and not a bot?" will be the same as the test validation result.

To keep websites accessible to the blind and people with impaired vision – for whom reading the test images could be a problem – BotDetect also provides a sound test alternative, pronouncing the textual code to users who prefer to hear it.
