  • Software self-checking systems and methods
    Patent number: 10423779
    Abstract: 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: Grant
    Filed: March 14, 2018
    Date of Patent: September 24, 2019
    Assignee: Intertrust Technologies Corporation
    Inventors: William G. Horne, Lesley R. Matheson, Casey Sheehan, Robert E. Tarjan
