Patent number: 8370634Abstract: 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: GrantFiled: May 20, 2010Date of Patent: February 5, 2013Assignee: Intertrust Technologies Corp.Inventors: William G. Horne, Umesh Maheshwari, Robert E. Tarjan, James J. Homing, W. Olin Sibert, Lesley R. Matheson, Andrew K. Wright, Susan Owicki

Patent number: 7823135Abstract: 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: April 7, 2005Date of Patent: October 26, 2010Assignee: Intertrust Technologies CorporationInventors: James J. Horning, W. Olin Sibert, Robert E. Tarjan, Umesh Maheshwari, William G. Horne, Andrew K. Wright, Lesley R. Matheson, Susan Owicki
