Abstract

The present invention provides a method for tracking of digital assets within a system through the use of digital serial numbers. Systems equipped with the present invention can uniquely identify copies of assets within it. Assets that originate within the system can be uniquely identified even outside the system. Their transaction history within the system can be traced by looking up the transaction history associated with an assets'"'"' serial number. The serial number applied to an asset is unique to each transaction and applied at the time a copy is made. Database entries are created that link each unique serial number to aspects of the transaction. Each serial number references details about a particular transaction such as parties involved, date and time of copy, ownership, terms of use, and payment terms. Using the present invention any copy of an asset within the system can be copied to another part of the system as if it were the original and with the accompanying terms and conditions in effect for that original at the time of transfer. The serial number does not noticeably interfere with the intended usage of the asset. Serial numbers can be applied to any asset media type or format.

further wherein said second digital asset has no copy protection and can be transferred from said second computer to a third computer by said customer without requiring an additional authorization from said first computer.

17. A method of exchanging digital assets over a network, comprising the steps of:

(a) storing a digital asset on a first computer coupled to the network, which digital asset includes both digital content and a first unique identifier associated with a first instantiation of said digital asset; and

(b) setting up a customer account with said first computer including an authorization to play said digital asset on a second computer coupled to said first computer over the network; and

(c) creating a second instantiation of said digital asset, including a second unique identifier;

wherein said second unique identifier includes customer information associated with a customer for said digital asset;

(d) storing said second instantation of said digital asset at said second computer;

wherein said digital asset has no copy protection and can be transferred from said second computer to a third computer by said customer without requiring an additional authorization from said first computer.

18. The method of claim 17, further including a step:
