Invention to prevent automated robots from submitting web forms using verbal reasoning

For certain web applications, such as registration for web space and email accounts, there is a risk that the application can be accessed by an automated agent - and then used to publish or proliferate spam. In order to prevent this, there are current solutions which ensure that the web form is being submitted by a human being rather than by an agent. These rely on the web application publishing a code (a series of letters and numbers) on the form which must be typed in correctly in order to submit the form. The code is disguised, by converting it into an image which is then distorted in such a way that makes it difficult to interpret electronically, but relatively easy to decipher for a human.

There are problems with this solution:
- The disguised code is sometimes so well disguised as to make it difficult for a human to decipher
- The code cannot be automatically read by someone with a visual impairment and this means the web application has to provide a sound recording of the code for these users

    This invention would implement a similar solution to the problem, but instead of using a disguised code, the invention would publish an undisguised question in plain text. In order to submit the form, the user would need to answer the question correctly. The answer to the question is contained in the question itself, and can be determined by li...
