Abstract
The present invention is directed to systems for and methods of controlling access to computer systems. A method in accordance with the present invention comprises performing a test that includes comparing input responses to randomly selected questions with corresponding pre-determined responses to the questions and granting access to the system in the event the test is passed. A first condition of passing the test is that each input response matches a corresponding pre-determined response. Once passing the test, the user is granted permissions to access data based on his position. For example, a corporate director generally has greater permissions than an engineer. Preferably, the user's permissions determine an encryption key and a decryption key that the user is able to use to access protected data.
