Abstract

A method and system of providing movies or other content is provided where a flash drive or flash memory card is used in place of DVD'"'"'s or other formats. A user receives the content on the flash drive from a kiosk. The system ensures that a codec supported by the player of the user will be utilized to encode the content, or in certain embodiments a corresponding codec is provided along with the movie. Authentication and encryption mechanisms ensure that the movie is only provided to an authentic card and/or player from a kiosk, so that the movies cannot be provided to flash devices that do not have proper security mechanisms to safeguard the content or to those not authorized to otherwise receive the movie.

Claims

1. A method of supplying content to an individual, the method comprising:

receiving a memory card in a receptacle of a kiosk for distributing the content;

performing a first verification, the first verification of the authenticity of the memory card, and occurring while in the receptacle of the kiosk, by comparing first and second keys of an RSA key pair;

performing a second verification, the second verification of the memory card and the user, by verifying a public key certificate chain issued by a certificate authority, and if both the first and second verification are successful, thereafter,

creating a container file;

placing the content within a media file in the container file;

placing a pluggable decoding module in the container file; and

transferring the container file from the kiosk to the memory card.

2. The method of claim 1, further comprising storing the RSA key pair, a first key of the key pair in the kiosk and a second key of the key pair in the memory card or a player used with the memory card.

3. The method of claim 1, wherein a public key of the public key certificate is stored in the memory card by the player.

4. The method of claim 3, wherein the transferred content is encrypted using the public key of the player.

5. The method of claim 4, wherein the transferred content is encrypted using a key of the kiosk.

6. The method of claim 1, further comprising receiving payment at the kiosk for the content.

7. The method of claim 1, further comprising checking a validity period of the content, and if playback of the content is requested during the validity period, playing the content on the card.

8. The method of claim 4, further comprising checking a validity period of the content, and decrypting the content with a private key of the player if playback of the content is requested during the validity period, but not if the content is requested outside of the validity period.

9. A method of supplying digitally encoded content to an individual, the method comprising:

storing, in a memory of a transportable flash memory mass storage device, an indication of the encoding formats supported by a player for use with the mass storage device;

monitoring, for an insertion of the mass storage device within a receptacle of a digital kiosk, and when insertion is detected;

performing a first verification, the first verification of the mass storage device, and occurring while in the receptacle of the kiosk, by comparing first and second keys of an RSA key pair;

performing a second verification, the second verification of a player of the user, by verifying a public key certificate chain issued by a certificate authority, and if both the first and second verification are successful, transferring, from the kiosk to the mass storage device, the content in one or more of the supported content encoding formats; and

performing a third verification, the third verification taking place while the mass storage device is coupled to the player, the third verification verifying that content selected for playback is within a validity period associated with the content.

10. The method of claim 9 further comprising encrypting the content prior to transfer with a product of the RSA key pair.

11. The method of claim 9 wherein the product comprises a content key encrypted with a public key of the RSA keypair.

12. The method of claim 10, further comprising decrypting the content post transfer with a product of the RSA key pair.

13. The method of claim 11, further comprising decrypting the content key with a private key of the RSA keypair.

14. The method of claim 13, further comprising decrypting the content post transfer with the decrypted content key.

15. A method of supplying content to an individual, the method comprising:

storing, in a memory of a memory card, an indication of one or more encoding formats supported by a player used with the memory card;

receiving the memory card in a receptacle of a kiosk for distributing the content;

performing a first verification, the first verification of the authenticity of the memory card, and occurring while in the receptacle of the kiosk, by comparing first and second keys of an RSA key pair;

performing a second verification, the second verification of the memory card and the user, by verifying a public key certificate chain issued by a certificate authority; and

,

if both the first and second verification are successful, transferring, from the kiosk to the memory card, the content in one or more of the supported content encoding formats.

16. The method of claim 15, further comprising storing the RSA key pair, a first key of the key pair in the kiosk and a second key of the key pair in the player or the memory card.

17. The method of claim 15, wherein a public key of the public key certificate is stored in the memory card by the player.

18. The method of claim 17, wherein the transferred content is encrypted using the public key of the player.

19. The method of claim 18, wherein the transferred content is encrypted using a key of the kiosk.

20. The method of claim 15, further comprising receiving payment at the kiosk for the content.

21. The method of claim 15, further comprising transferring an indication of the validity period of the content, from the kiosk to the card.

22. The method of claim 21, further comprising checking the validity period of the content, and if playback of the content is requested during the validity period, playing the content on the card.

23. The method of claim 21, further comprising checking the validity period of the content, and decrypting the content with a private key of the player if playback of the content is requested during the validity period.

24. The method of claim 15, wherein the card is a micro SD card format or an SD card format.
