Patent number: 8035320Abstract: The present invention addresses the problem of providing illumination in a manner that is energy efficient and intelligent. In particular, the present invention uses distributed processing across a network of illuminators to control the illumination for a given environment. The network controls the illumination level and pattern in response to light, sound, and motion. The network may also be trained according to uploaded software behavior modules, and subsets of the network may be organized into groups for illumination control and maintenance reporting.Type: GrantFiled: April 18, 2008Date of Patent: October 11, 2011Inventor: W.

Publication number: 20110246782Abstract: Systems and methods are provided for protecting electronic content from the time it is packaged through the time it is experienced by an end user. Protection against content misuse is accomplished using a combination of encryption, watermark screening, detection of invalid content processing software and hardware, and/or detection of invalid content flows. Encryption protects the secrecy of content while it is being transferred or stored. Watermark screening protects against the unauthorized use of content. Watermark screening is provided by invoking a filter module to examine content for the presence of a watermark before the content is delivered to output hardware or software. The filter module is operable to prevent delivery of the content to the output hardware or software if it detects a predefined protection mark. Invalid content processing software is detected by a monitoring mechanism that validates the software involved in processing protected electronic content.Type: ApplicationFiled: June 14, 2010Publication date: October 6, 2011Applicant: Intertrust Technologies CorporationInventors: Michael K. MacKay, W. Olin Sibert, Richard A. Landsman, Eric J. Swenson, William Hunt

Publication number: 20110173409Abstract: A hardware Secure Processing Unit (SPU) is described that can perform both security functions and other information appliance functions using the same set of hardware resources. Because the additional hardware required to support security functions is a relatively small fraction of the overall device hardware, this type of SPU can be competitive with ordinary non-secure CPUs or microcontrollers that perform the same functions. A set of minimal initialization and management hardware and software is added to, e.g., a standard CPU/microcontroller. The additional hardware and/or software creates an SPU environment and performs the functions needed to virtualize the SPU's hardware resources so that they can be shared between security functions and other functions performed by the same CPU.Type: ApplicationFiled: March 23, 2011Publication date: July 14, 2011Inventor: W. Olin Sibert

Patent number: 7979542Abstract: The present invention provides systems and methods for conducting electronic transactions in a distributed computing environment. A communications protocol is provided that enables reliable transactional state synchronization for peers participating in a distributed transaction. A transaction processing application is deployed on a local computer system to manage transactions thereon. The local computer system contacts a remote computer system to obtain authorization to execute a transaction. The local computer system initiates a failure-recovery job that is operable to automatically resend status signals and other information to the remote system if the communication with the remote system exhibits certain predefined fault conditions. The remote system is able to dynamically adjust the definition of the predefined fault conditions. If the transaction concludes without triggering the predefined fault conditions, the failure-recovery job is cancelled.Type: GrantFiled: March 12, 2009Date of Patent: July 12, 2011Assignee: Intertrust Technologies CorporationInventors: Marc E. Strohwig, John M. McGinty, W. Olin Sibert

Publication number: 20110131422Abstract: 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—which may be a trusted independent third party—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)—allowing one tamper resistance work factor environment to protect itself against load modules from another, different tamper resistance work factor environment.Type: ApplicationFiled: February 4, 2011Publication date: June 2, 2011Inventors: Victor H Shear, W. Olin Sibert, David M. Van Wie

Patent number: 7940928Abstract: A technique for integrating message authentication with encryption and decryption is disclosed. Intermediate internal states of the decryption operation are used to generate a validation code that can be used to detect manipulation of the encrypted data. The technique is optimized with respect to processing time, execution space for code and runtime data, and buffer usage. The technique is generally applicable to a variety of block ciphers, including TEA, Rijndael, DES, RC5, and RC6.Type: GrantFiled: February 29, 2008Date of Patent: May 10, 2011Assignee: Intertrust Technologies CorporationInventor: W.

Publication number: 20110083009Abstract: A novel method and apparatus for protection of streamed media content is disclosed. In one aspect, the apparatus includes control means for governance of content streams or content objects, decryption means for decrypting content streams or content objects under control of the control means, and feedback means for tracking actual use of content streams or content objects. The control means may operate in accordance with rules received as part of the streamed content, or through a side-band channel. The rules may specify allowed uses of the content, including whether or not the content can be copied or transferred, and whether and under what circumstances received content may be “checked out” of one device and used in a second device. The rules may also include or specify budgets, and a requirement that audit information be collected and/or transmitted to an external server. In a different aspect, the apparatus may include a media player designed to call plugins to assist in rendering content.Type: ApplicationFiled: October 5, 2010Publication date: April 7, 2011Inventors: Talal G. Shamoon, Ralph D. Hill, Chris D. Radcliffe, John P. Hwa, W. Olin Sibert, David M. Van Wie

Publication number: 20110035733Abstract: Systems and methods are disclosed for protecting a computer program from unauthorized analysis and modification. Obfuscation transformations can be applied to the computer program's local structure, control graph, and/or data structure to render the program more difficult to understand and/or modify. Tamper-resistance mechanisms can be incorporated into the computer program to detect attempts to tamper with the program's operation. Once an attempt to tamper with the computer program is detected, the computer program reports it to an external agent, ceases normal operation, and/or reverses any modifications made by the attempted tampering. The computer program can also be watermarked to facilitate identification of its owner. The obfuscation, tamper-resistance, and watermarking transformations can be applied to the computer program's source code, object code, or executable image.Type: ApplicationFiled: August 11, 2010Publication date: February 10, 2011Applicant: Intertrust Technologies Corp.Inventors: James J.
