US Patent:
6763464, Jul 13, 2004
Filed:
Jul 18, 2002
Appl. No.:
10/196953
Inventors:
Xin Wang - Los Angeles CA
Thanh T. Ta - Huntington Beach CA
Prasad Ram - Manhattan Beach CA
Assignee:
ContentGuard Holdings, Inc. - Wilmington DE
International Classification:
G06F 1216
US Classification:
713193, 713160, 380 45, 380201, 705 51, 705 57
Abstract:
A system and method for the secure distribution of electronic documents reduces the likelihood of unauthorized reproduction and redistribution by either authorized or unauthorized recipients. A self-protecting document (SPD) contains an encrypted document as well as a secure set of permissions and the software necessary to process the document; full decryption of the document is performed as late as possible so as to minimize the possibility of intercepting the document before it has been fully rendered to screen or to paper.

US Patent:
6859533, Feb 22, 2005
Filed:
Dec 21, 1999
Appl. No.:
09/469487
Inventors:
Xin Wang - Los Angeles CA, US
Thanh T. Ta - Huntington Beach CA, US
Assignee:
ContentGuard Holdings, Inc. - Wilmington DE
International Classification:
H04L009/28
US Classification:
380 28, 380259
Abstract:
Methods for transferring among key holders in encoding and cryptographic systems the right to decode and decrypt messages in a way that does not explicitly reveal decoding and decrypting keys used and the original messages. Such methods are more secure and more efficient than typical re-encoding and re-encryption schemes, and are useful in developing such applications as document distribution and long-term file protection.

Systems And Methods For Integrity Certification And Verification Of Content Consumption Environments

US Patent:
6931545, Aug 16, 2005
Filed:
Aug 28, 2000
Appl. No.:
09/649838
Inventors:
Thanh Ta - Huntington Beach CA, US
Xin Wang - Los Angeles CA, US
Assignee:
ContentGuard Holdings, Inc. - Wilmington DE
International Classification:
G06F011/30
G06F012/14
H04L009/32
H04L009/00
US Classification:
713200, 713156, 713187
Abstract:
A content provider, such as a document publisher or distributor, provides, for example, protected content to a user, for consumption within a trusted user environment. By providing integrity certification and verification services, the authenticity of the content consumption environments can be verified. The content provider forwards to the user a protected version of the digital content which includes, for example, a license agreement and an integrity profile identification. The profile includes, for example, the applications and system components that are allowed to be used in conjunction with the protected content. Additionally, the content provider initiates a request for an integrity profile. This request for the integrity profile is forwarded to an integrity certification and verification device. The integrity certification and verification device can, for example, if an integrity profile does not already exist for the requested applications and/or systems components, query a content consumption system/application provider, who, for example, has supplied the system components to the user.

US Patent:
7068787, Jun 27, 2006
Filed:
Mar 24, 2000
Appl. No.:
09/534756
Inventors:
Thanh T. Ta - Huntington Beach CA, US
Prasad Ram - Manhattan Beach CA, US
Robert E. Schuler - Hermosa Beach CA, US
Arun Ramanujapuram - Redondo Beach CA, US
Guillermo Lao - Torrance CA, US
Xin Wang - Los Angeles CA, US
Assignee:
Contentguard Holdings, Inc. - Wilmington DE
International Classification:
G06F 7/167
US Classification:
380240, 380200, 380201, 713193, 705 57
Abstract:
A digital work and a system context (or resource information or system resource) are polarized enabling trusted rendering or replay of the digital work without depolarization of the digital content. The digital work includes digital content and resource information. Resource information may include information used by a replay application to format or process the digital content. The digital work and system context are polarized using a polarization scheme which relies on a polarization seed to initialize and customize the polarization. Different types of polarization seeds may be used, including a random number, a user's system's state or characteristic and a dynamic state-based polarization seed based on a dynamic system state or characteristic.

Abstract:
A method and system for managing the state of a protected resource in a system for granting access to a protected resource in accordance with usage rights. The usage rights include at least one state variable indicating a status of an associated protected resource. A message related to the state variable is transmitted from a resource control device to an interface framework. The resource control device is coupled to the resource to control use of the resource by enforcing the usage right. A state controller operative to track the value of the state variable is loaded into the framework and instructed to manipulate the value of the state variable in accordance with said message. For example, the message can be a query of the current value of the state variable.

Abstract:
A system and method of controlling use of content in accordance with usage rights associated with the content. A request for content is analyzed by looking for a signature from a user device making the request to determine if the user device has security components for enforcing the usage rights. If the request does not have the signature, a software agent is sent to the user device to determine if the user device is secure and the request is resent with the signature if the user device is secure. Content is rendered with a rendering engine of the user device in accordance with the usage rights in response to the resent request.
