Abstract

A system for transferring verified media data. The system comprising: an item of content storing the media data, and having an associated serial number; a computing device including a first storage device and a network interface; a secure copying application program; a secure copy of the media data generated by the secure copying application program and stored on the first storage device; a verification server including a serial number database and having a network connection to the computing device through the network interface, wherein the secure copying application program generates the secure copy after verifying the serial number is valid and active by communicating with the verification server; and a portable copy of the media data, including license information, generated from the secure copy by the secure copying application program.

Claims

1. A method for transferring media data stored in an item of content using a computing device, the method comprising:

receiving, by the computing device, the item of content;

wherein the item of content includes the media data and a serial number associated with the media data;

extracting, by the computing device, the media data and a serial number associated with the media data from the received item of content;

storing, by the computing device, the extracted media data;

receiving, by the computing device, an indication that the associated serial number with the received media data has been determined to be valid and in active status;

generating, by the computing device, a secure copy of the received media data;

receiving, by the computing device, license information based on the associated serial number determined to be valid and in active status;

generating, by the computing device, a portable copy of the media data including the received license information of the media data using the generated secure copy of the media data; and

transferring, by the computing device, the generated portable copy of the media data including the received license information of the media data to a portable device.

2. The method of claim 1, wherein the media data is stored on an-the item of content which includes a digital video disk (DVD).

3. The method of claim 1, wherein the license information includes limitations on the use of the portable copy of the media data.

4. The method of claim 3, wherein the limitations are modified for the portable copy made after a certain number of copies of the portable copy is made.

5. The method of claim 3, further comprising resetting the limitations on the use of the portable copy by connecting the portable device to the computing device.

6. The method of claim 1, further comprising storing a license management program on the portable device to process and control access to the portable copy of the media data on the portable copy device according to the license information.

7. The method of claim 1, wherein the portable device includes a laptop computer.

8. The method of claim 1, wherein the portable device includes an MP3 player.

9. A non-transitory tangible storage medium storing a computer program, to transfer media data stored in an item of content using a computing device, the computer program comprising executable instructions when executed by a processor, causes the processor to perform the steps of:

receiving the item of content;

wherein the item of content includes the media data and a serial number associated with the media data;

extracting the media data and a serial number associated with the media data from the received item of content;

receiving the extracted media data;

receiving an indication that the associated serial number with the received media data has been determined to be valid and in active status;

generating a secure copy of the received media data;

receiving, license information based on the associated serial number determined to be valid and in active status;

generating a portable copy of the media data including the received license information of the media data using the generated secure copy of the media data; and

transferring the generated portable copy of the media data including the received license information of the media data to a portable device.

10. The non-transitory tangible storage medium of claim 9, wherein the media data is stored on an-the item of content which includes a digital video disk (DVD).

11. The non-transitory tangible storage medium of claim 9, wherein the license information includes limitations on the use of the portable copy of the media data.

12. The non-transitory tangible storage medium of claim 11, wherein the limitations are modified for the portable copy made after a certain number of copies of the portable copy is made.

13. The non-transitory tangible storage medium of claim 11, further comprising the step of:

resetting the limitations on the use of the portable copy by connecting the portable device to the computing device.

14. The non-transitory tangible storage medium of claim 9,

further comprising the step of:

storing a license management program on the portable device to process and control access to the portable copy of the media data on the portable copy device according to the license information.
