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 digital repository of digitally encoded content, the digitally encoded content of the type to be protected from unauthorized distribution, the repository located in a publicly accessible establishment and comprising:

a hardware interface for making a direct connection of a portable flash memory mass storage device; and

an authentication mechanism that verifies that the mass storage device is a genuine approved type of mass storage device with security measures that restrict unauthorized duplication of content residing in the mass storage device,

wherein the repository communicates with the mass storage device and reads an indication of encoding formats suitable for use with a player that has previously interfaced with the mass storage device.

2. The digital repository of claim 1 wherein the hardware interface comprises a receptacle.

3. The digital repository of claim 1 wherein the hardware interface comprises a near field communications transceiver.

4. The digital repository of claim 1 wherein the authentication mechanism utilizes a public key infrastructure.

5. The digital repository of claim 1, wherein the repository is operable to transfer a portion of the digitally encoded content from the repository to the mass storage device, in a format it has determined is supported by the player.

6. The digital repository of claim 1, wherein the repository further provides a decoder to the mass storage device in order to playback the content with the player.

7. The digital repository of claim 2, wherein the repository is further operable to transfer an indication of a validity period of the content.

8. The digital repository of claim 3, wherein the indication of the validity period is contained within a PKI certificate.

9. A digital repository of digitally encoded content, the digitally encoded content of the type to be protected from unauthorized distribution, the repository located in a publicly accessible establishment and comprising:

a hardware interface for making a direct connection of a portable flash memory mass storage device; and

an authentication mechanism, utilizing a public key infrastructure, that verifies that the mass storage device is a genuine approved type of mass storage device with security measures that restrict unauthorized duplication of content residing in the mass storage device,

wherein the repository queries the mass storage device for information regarding encoding formats suitable for use with a player to be used with the mass storage device.

10. A system for distributing digitally encoded movies, the system comprising:

a portable flash memory mass storage device;

a player operable to play back the movie from the portable flash memory mass storage device; and

a kiosk comprising a receptacle or radio frequency interface compatible with the portable flash memory mass storage device, the kiosk operable to connect with the portable flash memory mass storage device via the receptacle or radio frequency interface and authenticate the mass storage device using a public key certificate issued by a PKI certificate authority,

the kiosk further operable, if the mass storage device is authenticated, to load the movie into the mass storage device, encrypted with a public key of the public key certificate, together with an indication of a validity period of the movie,

the player operable to verify that the movie is within the validity period as a pre-requisite to decrypting the movie with the player private key and playing back the movie.
