Software self-checking systems and methods |
摘要 |
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.
