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: receiving an intellectual property product wherein the intellectual property product further comprises content data and rights data in digital form; storing the intellectual property product on a player, the player further comprising a player data record and wherein the player data record comprises component codes; comparing the rights data and the player data record to determine entitlement to play the content data; and playing the content data on the player if entitlement has been determined. ### Claim 2 (depends on 1) The method for securing intellectual property of claim 1 wherein the player is selected from the group consisting of a computer, a smart television, an MP3 player, a VCR, a set-top box; and a satellite receiver. ### Claim 3 (depends on 1) The method for securing intellectual property of claim 1 wherein the rights data comprises a player identifier, and wherein the player record further comprises a player specific identifier unique to the player, and wherein comparing the rights data and the player data record to determine entitlement to play the content data further comprises determining that the player identifier and the player specific identifier are the same. ### Claim 4 (depends on 1) The method for securing intellectual property of claim 1 wherein the rights data comprises a number of plays limit, and wherein the player record further comprises a number of plays counter, and wherein comparing the rights data and the player data record to determine entitlement to play the content data further comprises determining that the number of plays counter does not exceed the number of plays limit. ### Claim 5 (depends on 1) The method for securing intellectual property of claim 1 wherein the rights data comprises an end of play time, the player record further comprises a current time, and comparing the rights data and the player data record to determine entitlement to play the content data further comprises determining that the current time is not after the end of play time. ### Claim 6 (depends on 1) The method for securing intellectual property of claim 1 wherein the rights data comprises a last date, the player record further comprises a current date, and comparing the rights data and the player data record to determine entitlement to play the content data further comprises determining that the current date is not after the last date. ### Claim 7 (depends on 1) The method for securing intellectual property of claim 1 further comprising encrypting the content data before receiving an intellectual property product. ### Claim 8 (depends on 1) The method for securing intellectual property of claim 1 further comprising decrypting the content data before playing the content data on the player. ### Claim 9 (depends on 8) The method for securing intellectual property of claim 8 wherein decrypting the content data requires a private key and the private key is created from one or more component codes. ### Claim 10 (depends on 9) The method for securing intellectual property of claim 9 wherein the private key is unique to the player. ### Claim 11 A system for securing intellectual property distributed electronically comprising: a network; a player connected to the network, the player comprising a processor, a storage device connected to the processor, and memory; the storage device further comprising a player data record; the player data record further comprising component codes; and the memory including software instructions, the software instructions comprising instructions for: receiving over the network an intellectual property product wherein the intellectual property product further comprises content data and rights data in digital form; storing the intellectual property product in the storage device, comparing the rights data and the player data record to determine entitlement to play the content data; and playing the content data on the player if entitlement has been determined. ### Claim 12 (depends on 11) The system for securing intellectual property of claim 11 wherein the player is selected from the group consisting of a computer, a smart television, an MP3 player, a VCR, a set-top box; and a satellite receiver. ### Claim 13 (depends on 11) The system for securing intellectual property of claim 11 wherein the rights data comprises a player identifier, and wherein the player record further comprises a player specific identifier unique to the player, and wherein the software instructions for comparing the rights data and the player data record to determine entitlement to play the content data further comprises instructions for determining that the player identifier and the player specific identifier are the same. ### Claim 14 (depends on 11) The system for securing intellectual property of claim 11 wherein the rights data comprises a number of plays limit, and wherein the player record further comprises a number of plays counter, and wherein the software instructions for comparing the rights data and the player data record to determine entitlement to play the content data further comprises instructions for determining that the number of plays counter does not exceed the number of plays limit. ### Claim 15 (depends on 11) The system for securing intellectual property of claim 11 wherein the rights data comprises an end of play time, the player record further comprises a current time, and wherein the software instructions for comparing the rights data and the player data record to determine entitlement to play the content data further comprises instructions for determining that the current time is not after the end of play time. ### Claim 16 (depends on 11) The system for securing intellectual property of claim 11 wherein the rights data comprises a last date, the player record further comprises a current date, and the software instructions for comparing the rights data and the player data record to determine entitlement to play the content data further comprises instructions for determining that the current date is not after the last date. ### Claim 17 (depends on 11) The system for securing intellectual property of claim 11 wherein the content data is encrypted and wherein the software instructions further comprise software instructions for decrypting the content data. ### Claim 18 (depends on 17) The system for securing intellectual property of claim 17 wherein decrypting the content data requires a private key and the private key is created from one or more component codes. ### Claim 19 (depends on 17) The system for securing intellectual property of claim 17 wherein the private key is unique to the player.
