Abstract

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.”

wherein the tamper-resistant software is operable to impede users of the electronic appliance from circumventing the one or more electronic permissions.

2. The rights management system of claim 1, in which at least one of the one or more of the electronic permissions is electronically transmitted to the electronic appliance independently of an electronic content item to which the at least one of the one or more electronic permissions relates.

3. The rights management system of claim 1, further comprising a central processing unit operatively coupled to the secure processing unit.

4. The rights management system of claim 3, in which the secure processing unit is operable to decrypt, at least in part, the at least one content item.

5. A secure processing unit, the secure processing unit comprising:

non-volatile memory, the non-volatile memory including at least one cryptographic key for use, at least in part, in decrypting a piece of electronic content in accordance with rules associated with the piece of electronic content;

a processor; and

a tamper-resistant housing, the tamper-resistant housing being operable to impede unauthorized access to the cryptographic key.

6. The secure processing unit of claim 5, in which the non-volatile memory further includes at least one of said rules.

7. The secure processing unit of claim 6, in which the non-volatile memory further includes programming for decrypting the piece of electronic content using the at least one cryptographic key.

8. A method comprising:

receiving, at an electronic appliance, an electronic content item, the electronic content item being encrypted at least in part;

storing the electronic content item in memory of the electronic appliance;

receiving, at the electronic appliance, a rule specifying one or more permitted uses of the electronic content item;

receiving, at the electronic appliance, a request to use the electronic content item;

determining that the requested use of the electronic content item corresponds to a permitted use of the electronic content item specified in the rule; and

using, at least in part, a decryption key to decrypt the electronic content item, the decryption key being stored in a secure processing unit contained in the electronic appliance.
