A security system and method for authenticating a user's access to a system is disclosed. The security system receives an authentication request from the user and responds by generating a security matrix based on a previously stored user keyword and user preference data, the security matix being different for each authentication request. The security system sends the security matrix to the user and awaits a one-time code in response to the security matrix. The user forms the one-time code based on the user keyword, the user preferences, and the security matrix. The security system validates the one-time code against the security matrix, the keyword, and the user preferences, and responds by sending an authentication result to the user that either permits or denies access to the system. Additionally, the security system sends a success or fail message to the system to be accessed. |
