“CAPTCHA” Protects from Automated Attacks – A Security Mechanism Deployed in Student Webmail

To protect your computer account from automated attacks, a security mechanism “CAPTCHA” is deployed in Student Webmail (http://studmail.umac.mo).                          

CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. It is a challenge-response test to ensure that the password is typed-in by a person rather than a computer program.

In normal condition, user needs to input User ID and password to access the Student Webmail.

However, if you failed to login for more than 3 times, an image of distorted text and audio-based CAPTCHAs will be displayed. It is necessary to enter “CAPTCHA” code (shown on login screen) before login for security reason.
