Abstract

A password management system is based on a complex password format having two portions, a first portion which stays the same and a second portion which can be regularly updated. The first portion may for example be a Personal Identification Number (“PIN”) and which is memorable. The second portion meanwhile does not have to be memorable. The password management system works with an operating system which uses passwords matched in length to the complex password format. The passwords can be regularly updated by the password management system by providing a fresh second portion of the complex password. This is put together with the existing first portion and the whole is used as an update of the password records in the managed operating system. At the same time, the fresh portion of the password is made available to the relevant user, for instance via a mobile telephone. The user can then reconstruct the updated complex password by adding the memorable first portion to the fresh portion they have received.

Claims

1. A password management system, the system comprising:

a password updater for updating a password stored in a first storage location, said stored password comprising a combination of a first portion and a second portion;

a password change controller for controlling changes in the second portion of the stored password; and

a password change output for outputting changes made by said controller in said second portion to one or more second storage locations;

wherein the password updater is adapted to update the password stored in the first storage location to comprise said first portion in combination with a second portion changed by the password change controller, which changed second portion is then available at or via the one or more second storage locations by means of the password change output.

2. A system according to claim 1, further comprising a password portion store for storing copies of first portions of passwords stored in said first storage location, wherein the password updater is adapted to assemble an updated password for use in updating the password stored in the first storage location by reading a first portion of the password from the password portion store and combining with it the second portion provided by the password change controller.

3. A system according to claim 1 wherein the password updater is adapted to update the password stored in the first storage location by sending the first portion together with the changed second portion to provide an updated password.

4. A system according to claim 1 wherein the first storage location comprises a password store for an authentication process in a software-based system.

5. A system according to claim 2 wherein said password store is constructed to store unitary passwords.

6. A system according to claim 1 wherein the second storage location is accessible via a user device.

7. A system according to claim 6 wherein said user device is a mobile device.

8. A system according to claim 1 wherein the first portion of the password comprises a personal identification number.

9. A system according to claim 8, further comprising a user profile store for storing personal identification numbers, each for use as a first portion of a password in respect of a user.

10. A system according to claim 1 wherein the second portion of the password comprises a random code.

11. A system according to claim 1 wherein the password change controller comprises a code generator for generating new code for use in changing the second portion of the stored password.

12. A system according to claim 1 wherein the password change controller is adapted to run a batch update of user passwords stored in relation to an authentication process in a software-based system.

13. A system according to claim 1, further comprising an update request input and wherein the password change controller is adapted to run an update of a single user password stored in relation to an authentication process in a software-based system, in response to receiving an update request at said input.

14. A system according to claim 1 wherein the second storage location is provided by a mobile user device.

15. A system according to claim 1 wherein the password change output is adapted to send changes in said second portion to one or more second storage locations by use of simple message system messages.

16. A system according to claim 1 wherein the password change output is adapted to send changes in said second portion to one or more second storage locations by use of facsimile transmission.

17. A system according to claim 1 wherein the password change output is adapted to send changes in said second portion to one or more second storage locations by use of voice messaging.

18. A system according to claim 1 wherein the password change output is adapted to send changes in said second portion to one or more second storage locations by use of paging.

19. A system according to claim 1 wherein the password change output is adapted to send changes in said second portion to one or more second storage locations by use of email.

20. A system according to claim 1 wherein the password change output is adapted to send changes in said second portion to one or more second storage locations by use of an Internet-based message service.

21. A method of updating a password stored for use in an authentication process, the method comprising:

assembling an updated password by referring to a data store for a first portion of the updated password and adding a fresh second portion thereto;

resetting the password stored for use in the authentication process to the updated password; and

making the fresh portion accessible to or via a user device.
