Abstract
Systems and methods for changing a user password are described. In one embodiment, the method includes determining at least one password equivalent value, determining a safe-to-transmit password value, determining a password change authentication value, transmitting, from a remote device to a controller, the password change authentication value and the safe-to-transmit password value, confirming the data integrity of the password change authentication value sent from the remote device to the controller, and storing a new password equivalent value.
Claims20
A method for changing a user password, said method comprising:
- determining at least one password equivalent value;
- determining a safe-to-transmit password value;
- determining a password change authentication value;
- transmitting, from a remote device to a controller, the password change authentication value and the safe-to-transmit password value;
- confirming the data integrity of the password change authentication value transmitted from the remote device to the controller;
- and
- storing a new password equivalent value.
A system of access protection for a controller, said system comprising:
- a controller configured to:
- transmit a password change operation web page to a user-operated web browser;
- determine a password change authentication value;
- receive a password change authentication value;
- compare the password change authentication value with a password change authentication value transmitted by a user-operated web browser;
- determine a new password equivalent value;
- and
- store the new password equivalent value;
- and
- a user-operated web browser configured to:
- display a password change operation web page;
- determine a current password equivalent value;
- determine a new password equivalent value;
- determine a safe-to-transmit password value;
- determine a password change authentication value;
- and
- transmit the password change authentication value and the safe-to-transmit password value to the controller.
A method for changing a user password on a controller, said method comprising:
- determining a current password equivalent value;
- determining a new password equivalent value;
- determining a safe-to-transmit password value;
- determining a password change authentication value;
- transmitting, from a user-operated web browser to the controller, the password change authentication value and the safe-to-transmit password value;
- determining a password change authentication value to be stored by the controller;
- comparing the password change authentication value, stored by the controller, and the password change authentication value transmitted by the user-operated web browser to the controller;
- and
- storing the new password equivalent value.
