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.
