| The abbreviated word CAPTCHA sounds a bit weird. Nevertheless, we deal with it almost every day. The Internet is a lovely spot where users communicate, exchange information, do business in a cheap and convenient manner. But at the same time it is especially favoured by spammers, hackers and on-line fraudsters, with tons of spam and junk mail circulating around the global net. The IT term CAPTCHA is decoded as 'Completely Automated Public Turing test to tell Computers and Humans Apart'. It emerged in the year of 2000 as an internet protection module. It is a compulsory test that Internet users are to solve before posting an e-mail. There exist a lot of types of a CAPTCHA. Yet, on our computer monitors we most often see figures and characters frequently crossed with a line. Letters are not typed straight. Thus, it takes a user a few seconds to grasp what is typed in a prompt box. Some users will find the CAPTCHA test excessive. Yet, it is an essential preventative measure to shield your e-mail box from spam or junk mail. Actually it is the computer that creates a test & assesses if a user has managed to solve it. But the computer programme is incapable of solving a test itself. So, if you solve a test correctly, the computer will identifies you as human, as bots cannot solve a CAPTCHA test. This is the way the computer identifies users are human or bots. It is known that spam strongly assaults the World Wide Web. Surely, there are a number of anti-spam protection modules which sort out mail. Yet, Drupal CAPTCHA is viewed to be much more efficient. Along with the spam protection, the module secures the protection process, too. The Drupal CAPTCHA simply installs a test to be solved each time when users or guests are about to submit any form. As stated above, a CAPTCHA is in great demand in the XXI century. So, before you opt for a CAPTCHA service provider, assure it will meet your demands. There are also free trial versions you may get from potential service providers before you select a suitable one. Some CAPTCHA modules are well-compatible with a great number of programing languages. Do also ensure that your service provider will guarantee a backup server in a remote system to maintain a non-stop functioning of the software, if any problems occur. |
