Dynamic Self-Checking Techniques for Improved Tamper Resistance

We describe a software self-checking mechanism designed to improve the tamper resistance of large programs. The mechanism consists of a number of testers that redundantly test for changes in the executable code as it is running and report modifications. The mechanism is built to be compatible with copy-specific static watermarking and other tamper-resistance techniques. The mechanism includes several innovations to make it stealthy and more robust.
