| The abbreviation CAPTCHA sounds a bit odd. Nonetheless, we deal with it almost every single day. The Internet is a lovely spot where users communicate, exchange information, do business in a convenient and cheap manner. But simultaneously it is a paradise for spammers, hackers and online fraudsters, with loads of spam and junk mail spreading around the global net. The term CAPTCHA stands for 'Completely Automated Public Turing test to tell Computers and Humans Apart'. It appeared in the year of 2000 as anti-spam software. It is a mandatory test that users have to before posting an e-mail. There exist a great number of types of a CAPTCHA. Yet, the most widespread one that we usually come across is a set of numbers & letters very often crossed with a line. Characters are typed in various directions. Thus, it takes a user several seconds to read what is typed in a prompt box. Some Internet users may find the CAPTCHA test excessive. However, it is an all-important preventative measure to shield your e-mail box from spam & junk mail. In fact it is the computer that creates a test & assesses if a user has managed to solve it. But the computer program is unable to solve a test itself. So, if you have solved test correctly, the computer identifies you as human, because bots cannot solve a CAPTCHA. This is the way the computer identifies if users are human or bots. It is known that spam heavily attacks the Internet. Certainly, there are different anti-spam protection modules that sort out mail. However, Drupal CAPTCHA is thought to be a lot efficient. Along with the spam protection, the module secures the protection process, too. The Drupal CAPTCHA simply installs a mandatory test to be solved each time when users or guests are going to submit any form. As stated above, the CAPTCHA module is in great need now. So, when it comes to picking out a CAPTCHA service provider, make sure it will meet your demands. You can download a free trial version to view if a protection module suits you. Some CAPTCHA modules are compatible with a great number of programing languages. Do also insure that your service provider will guarantee an emergency server in an isolated network to maintain a non-stop running of the software, whatever problems may occur. |
