Patent number: 10423779Abstract: Software self-checking mechanisms are described for improving software tamper resistance and/or reliability. Redundant tests are performed to detect modifications to a program while it is running. Modifications are recorded or reported. Embodiments of the software self-checking mechanisms can be implemented such that they are relatively stealthy and robust, and so that they are compatible with copy-specific static watermarking and other tamper-resistance techniques.Type: GrantFiled: March 14, 2018Date of Patent: September 24, 2019Assignee: Intertrust Technologies CorporationInventors: William G. Horne, Lesley R. Matheson, Casey Sheehan, Robert E. Tarjan

Patent number: 10255414Abstract: 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: GrantFiled: June 5, 2015Date of Patent: April 9, 2019Assignee: Intertrust Technologies CorporationInventors: James J. Horning, W. Olin Sibert, Robert E. Tarjan, Umesh Maheshwari, William G. Horne, Andrew K. Wright, Lesley R. Matheson, Susan S. Owicki

Publication number: 20170300670Abstract: Systems and methods are disclosed for embedding information in software and/or other electronic content such that the information is difficult for an unauthorized party to detect, remove, insert, forge, and/or corrupt. The embedded information can be used to protect electronic content by identifying the content's source, thus enabling unauthorized copies or derivatives to be reliably traced, and thus facilitating effective legal recourse by the content owner. Systems and methods are also disclosed for protecting, detecting, removing, and decoding information embedded in electronic content, and for using the embedded information to protect software or other media from unauthorized analysis, attack, and/or modification.Type: ApplicationFiled: May 4, 2017Publication date: October 19, 2017Applicant: Intertrust Technologies CorporationInventors: William G. HORNE, Umesh MAHESHWARI, Robert E. TARJAN, James J. HORNING, W. Olin SIBERT, Lesley R. MATHESON, Andrew K. WRIGHT, Susan S. OWICKI
