Abstract

The computer security apparatus is appended to existing computer data file protection apparatus and operates as an adjunct thereto. The user invokes the password and/or data file encryption processes in the usual manner. If the user cannot remember the password used, the computer security apparatus presents a prerecorded password hint to the user in an attempt to jog the user'"'"'s memory to recall the password. If the initial password hint does not accomplish this goal, a succession of additional, more specific password hints, can be provided to ultimately induce the user to recall the password.

Claims

1. A password system for enabling a user to access data files stored on a computer system by providing a predefined password to said computer system, comprising:

means for storing data indicative of a password assigned to a user;

means for storing at least one hint that suggests said password to said user; and

means for displaying said at least one hint to said user.

2. The system of claim 1 wherein said hint storing means comprises:

means for storing data indicative of the identity of said user; and

means for storing data indicative of said at least one hint in a manner to associate said user with said at least one hint.

3. The system of claim 2 wherein said at least one hint comprises a succession of hints, said displaying means comprises:

means, responsive to said user failing to provide said password, for retrieving a first of said succession of hints from said hint storing means; and

means for transmitting said retrieved first hint to a display device for display to said user.

4. The system of claim 3 wherein said displaying means further comprises:

means, responsive to said user failing to provide said password upon receipt of a hint, for retrieving a next successive hint from said hint storing means; and

means for providing said retrieved next successive hint to said transmitting means for transmission to said display device.

5. The system of claim 4 wherein said displaying means further comprises:

means for successively activating said next successive hint retrieving means in response to said user failing to provide said password in response to a received password until no further hints are stored in said hint storing means for said user.

6. The system of claim 1 further comprising:

means, responsive to said user providing a password to said computer system, for comparing said provided password with said password stored in said storing means;

means, responsive to a failure to match said provided and stored passwords for activating said displaying means.

7. The system of claim 1 further comprising:

means, responsive to said user inputting data into said computer system indicative of a request for password hints, for activating said displaying means.

8. A method of password determination to enable a user to access data files on a computer system by providing a predefined password to said computer system, comprising the steps of:

storing data indicative of a password assigned to a user;

storing at least one hint in said memory that suggests said password to said user; and

displaying said at least one hint to said user.

9. The method of claim 8 wherein said step of hint storing comprises:

storing data indicative of the identity of said user; and

storing data indicative of said at least one hint in a manner to associate said user with said at least one hint.

10. The method of claim 9 wherein said at least one hint comprises a succession of hints, said step of displaying comprises:

retrieving, in response to said user failing to provide said password, for retrieving a first of said succession of hints from said memory; and

transmitting said retrieved first hint to a display device for display to said user.

11. The method of claim 10 wherein said step of displaying further comprises:

retrieving, in response to said user failing to provide said password upon receipt of a hint, a next successive hint from said memory; and

activating, using said retrieved next successive hint, said step of transmitting to send said next successive hint to said display device.

12. The method of claim 11 wherein said step of displaying further comprises:

successively activating said step of next successive hint retrieving in response to said user failing to provide said password in response to a received password until no further hints are stored in said memory for said user.

13. The method of claim 8 further comprising the steps of:

comparing, in response to said user providing a password to said computer system, said provided password with said password stored in said memory;

activating, in response to a failure to match said provided and stored passwords, said step of displaying.

14. The method of claim 8 further comprising the step of:

activating, in response to said user inputting data into said computer system indicative of a request for password hints, said step of displaying.
