Documents and other items can be delivered electronically from sender to recipient with a level of trustedness approaching or exceeding that provided by a personal document courier. A trusted electronic go-between can validate, witness and/or archive transactions while, in some cases, actively participating in or directing the transaction. Printed or imaged documents can be marked using handwritten signature images, seal images, electronic fingerprinting, watermarking, and/or steganography. Electronic commercial transactions and transmissions take place in a reliable, 'trusted' virtual distribution environment that provides significant efficiency and cost savings benefits to users in addition to providing an extremely high degree of confidence and trustedness. The systems and techniques have many uses including but not limited to secure document delivery, execution of legal documents, and electronic data interchange (EDI).

Trusted and secure techniques for item delivery and execution

Secure computation environments are protected from bogus or rogue load modules, executables and other data elements through use of digital signatures, seals and certificates issued by a verifying authority. A verifying authority&#x2014;which may be a trusted independent third party&#x2014;tests the load modules or other executables to verify that their corresponding specifications are accurate and complete, and then digitally signs the load module or other executable based on tamper resistance work factor classification. Secure computation environments with different tamper resistance work factors use different verification digital signature authentication techniques (e.g., different signature algorithms and/or signature verification keys)&#x2014;allowing one tamper resistance work factor environment to protect itself against load modules from another, different tamper resistance work factor environment. Several dissimilar digital signature algorithms may be used to reduce vulnerability from algorithm compromise, and subsets of multiple digital signatures may be used to reduce the scope of any specific compromise.

Systems and methods using cryptography to protect secure computing environments

The present inventions provide an integrated, modular array of administrative and support services for electronic commerce and electronic rights and transaction management. These administrative and support services supply a secure foundation for conducting financial management, rights management, certificate authority, rules clearing, usage clearing, secure directory services, and other transaction related capabilities functioning over a vast electronic network such as the Internet and/or over organization internal Intranets. These administrative and support services can be adapted to the specific needs of electronic commerce value chains. Electronic commerce participants can use these administrative and support services to support their interests, and can shape and reuse these services in response to competitive business realities. A Distributed Commerce Utility having a secure, programmable, distributed architecture provides administrative and support services. The Distributed Commerce Utility makes optimally efficient use of commerce administration resources, and can scale in a practical fashion to accommodate the demands of electronic commerce growth. The Distributed Commerce Utility may comprise a number of Commerce Utility Systems. These Commerce Utility Systems provide a web of infrastructure support available to, and reusable by, the entire electronic community and/or many or all of its participants. Different support functions can be collected together in hierarchical and/or in networked relationships to suit various business models and/or other objectives. Modular support functions can combined in different arrays to form different Commerce Utility Systems for different design implementations and purposes. These Commerce Utility Systems can be distributed across a large number of electronic appliances with varying degrees of distribution.

Trusted infrastructure support systems, methods and techniques for secure electronic commerce transaction and rights management

The present invention provides systems and methods for secure transaction management and electronic rights protection. Electronic appliances such as computers equipped in accordance with the present invention help to ensure that information is accessed and used only in authorized ways, and maintain the integrity, availability, and/or confidentiality of the information. Such electronic appliances provide a distributed virtual distribution environment (VDE) that may enforce a secure chain of handling and control, for example, to control and/or meter or otherwise monitor use of electronically stored or disseminated information. Such a virtual distribution environment may be used to protect rights of various participants in electronic commerce and other electronic or electronic-facilitated transactions. Distributed and other operating systems, environments and architectures, such as, for example, those using tamper-resistant hardware-based processors, may establish security at each node. These techniques may be used to support an all-electronic information distribution, for example, utilizing the 'electronic highway.'

Systems and methods for secure transaction management and electronic rights protection

The present invention provides systems and methods for electronic commerce including secure transaction management and electronic rights protection. Electronic appliances such as computers employed in accordance with the present invention help to ensure that information is accessed and used only in authorized ways, and maintain the integrity, availability, and/or confidentiality of the information. Secure subsystems used with such electronic appliances provide a distributed virtual distribution environment (VDE) that may enforce a secure chain of handling and control, for example, to control and/or meter or otherwise monitor use of electronically stored or disseminated information. Such a virtual distribution environment may be used to protect rights of various participants in electronic commerce and other electronic or electronic-facilitated transactions. Secure distributed and other operating system environments and architectures, employing, for example, secure semiconductor processing arrangements that may establish secure, protected environments at each node. These techniques may be used to support an end-to-end electronic information distribution capability that may be used, for example, utilizing the 'electronic highway.'

An integrated, modular array of administrative and support services are provided for electronic commerce and electronic rights and transaction management. These administrative and support services supply a secure foundation for conducting transaction-related capabilities over electronic networks, and can also be adapted to the specific needs of electronic commerce value chains. In one embodiment a Distributed Commerce Utility having a secure, programmable, distributed architecture provides these administrative and support services. The Distributed Commerce Utility may comprise a number of Commerce Utility Systems. These Commerce Utility Systems provide a web of infrastructure support available to, and reusable by, the entire electronic community and/or many of its participants. Different support functions can be collected together in hierarchical and/or networked relationships to suit various business models or other objectives. Modular support functions can be combined in different arrays to form different Commerce Utility Systems for different design implementations and purposes.
