Abstract: The disclosed technology can be used to develop systems and perform methods in which restriction, use, and/or interaction values can be assigned to license attributes associated with a first license to specify particular restrictions, uses (e.g., distribution), and interactions (e.g., manipulations) pertaining to a first protectable content. These restriction, use, and/or interaction values can be compared with corresponding attribute values associated with a second license and a second protectable content and such comparisons can serve as a basis for determining attributes associated with a third protectable content, where the third protectable content is based on a combination of at least some aspects of the first protectable content and the second protectable content.

Abstract: A system and method include means for processing a cryptographic certificate adapted to provide security functionality. A register means is provided and means for adjusting the register means to account for services when the cryptographic certificate is processed. In accordance with another aspect, a system and method include a register means for storing funds. Means are provided for processing a digital token providing proof of postage payment and means are also provided for processing a cryptographic certificate adapted to provide security functionality. Means debit funds stored in the register means when the digital token is processed and when the cryptographic certificate is processed. Processing the cryptographic certificate may involve many functions such as providing security services and/or certificate management functions (including generating and verifying cryptographic certificates) and/or key management functions and/or access to any needed private keys to perform security services.
