## Abstract

A system and method for securing intellectual property rights in distributed intellectual property. The present invention grants and polices rights in electronically distributed intellectual property. Use limitations are established by agreement by the content provider and the client. The use limitations are reflected in time-based, usage-based and player based component codes that are used to determine if the client is entitled to use the intellectual property. The present invention further protects the intellectual property from unauthorized use by encrypting the intellectual property with a key created from some or all of the component codes. As the component codes are known to both the client and the content provider, no key exchange is required by the present invention.

## Claims

### Claim 1

A method for securing intellectual property distributed electronically comprising:
establishing contact between an intellectual property provider server and a client player, wherein at least two component codes are shared and pre-stored in both the client player and the server prior to ordering the intellectual property, wherein at least two component codes are selected from the group consisting of a billing code, a player code, a time and date code, and a last cookie code;
ordering an intellectual property product from the intellectual property provider server;
the intellectual property server creating a shared private key based on the pre-stored shared component codes and an additional shared component code at the time the intellectual property product is ordered and wherein the shared private key is not distributed to the client player;
encrypting the intellectual property product with the shared private key prior to distribution to the client player, and wherein the intellectual property product further comprises content data and rights data in digital form;
receiving the intellectual property product at the client player;
storing the intellectual property product on the client player, the client player further comprising a player data record and wherein the player data record comprises the pre-stored shared component codes and the additional shared component code determined at the time the intellectual property product is ordered;
the client player creating the shared private key using a combination of the pre-stored shared component codes and the additional shared component code determined at the time the intellectual property product is ordered;
decrypting the intellectual property product with the created shared private key;
comparing the rights data and the player data record to determine entitlement to play the content data; and
playing the content data on the client player if entitlement to do so has been determined.

### Claim 8 (depends on 1)

The method for securing intellectual property of claim 1, wherein the additional shared component code is selected from the group consisting of a time and date code, a last cookie code, and a combination thereof.

### Claim 9 (depends on 8)

The method for securing intellectual property of claim 8, wherein the component codes are selected from the group consisting of a billing code, a player code in the form of a player, and a combination thereof.

### Claim 10

A system for securing intellectual property distributed electronically comprising:
a network;
a client player connected to the network, the client player comprising a processor, a storage device connected to the processor, and memory;
the storage device bearing a player data record;
the player data record comprising at least two component codes that have been shared with an intellectual property server during an earlier contact and an additional component code determined at a time an intellectual property product is ordered from the intellectual property server wherein at least two component codes are selected from the group consisting of a billing code, a player code, a time and date code, and a last cookie code; and
the memory including software instructions, the software instructions comprising instructions for:
the intellectual property server creating a shared private key based on the pre-stored shared component codes and an additional shared component code at the time the intellectual property product is ordered and wherein the shared private key is not distributed to the client player;
encrypting the intellectual property product with the shared private key prior to distribution to the client player, and wherein the intellectual property product further comprises content data and rights data in digital form;
receiving over the network the intellectual property product at the client player;
storing the intellectual property product in the storage device;
the client player creating the shared private key using a combination of the pre-stored shared component codes and the additional shared component code determined at the time the intellectual property product is ordered;
decrypting the intellectual property product with the created shared private key;
comparing the rights data and the player data record to determine entitlement to play the content data; and
playing the content data on the client player if entitlement to do so has been determined.
