RECAPTCHA FORMS END DATABASE SPAM

Anyone who has provided a forms-based entry application as part of their web presence knows the havoc that spammers and automated "bots" can have in populating a database with junk and even malicious code. Protecting against is this threat is high on the list most company's online web priorities.

One large, business-to-business company was having problems with their web forms being filled in and submitted to their database by automated bots. They turned to the Majec Systems team for a solution to help ensure that the forms were completed solely by humans, and that the solution was not so onerous as to prevent people from completing and submitting the form entries.

Majec turned to reCAPTCHA, which is "...a free CAPTCHA service that helps to digitize books, newspapers and old time radio shows." CAPTCHA (Completely Automated Public Turing Test To Tell Computers and Humans Apart) is:

...a program that protects websites against bots by generating and grading tests that humans can pass but current computer programs cannot. For example, humans can read distorted text as the one shown below, but current computer programs can't.

Majec registered the company's domain on the reCAPTCHA site and added necessary code to each of the ASP-based web form pages to require the CAPTCHA challenge to be completed and be correct before the submit function would write the form contents to the database.

Once this CAPTCHA challenge was put in place, the junk caused by the automated bots immediately ended. Maryanne Moore led the project for Majec Systems.
