A system that authenticates a user on a computer system. During operation, the system receives an authentication request from the user. Next, the system receives a first multimedia data item from the user. The system then performs a transformation on the first multimedia data item. Next, the system determines if the transformation of the first multimedia data item matches authentication data for the user, wherein the authentication data for the user is a transformation of a second multimedia data item. If so, the system authenticates the user. |

| Claim: |
14. The method of claim 4, wherein a location for a placement of a pattern in a multimedia file is associated with a feature of the first multimedia file; wherein the feature of the first multimedia file can include: an object within the first multimedia file; a time index within the first multimedia file; a note within the first multimedia file; and a melody within the first multimedia file. |
| Claim: |
15. A computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for authenticating a user on a computer system, wherein the method comprises: receiving an authentication request from the user; receiving a first multimedia data item from the user; performing a transformation on the first multimedia data item; determining if the transformation of the first multimedia data item matches authentication data for the user, wherein the authentication data for the user is a transformation of a second multimedia data item; and if so, authenticating the user. |
