Tracing Provenance and Detecting Tampering with Complementary LLM Watermarks

This work introduces a dual-signal watermarking scheme for LLM outputs that simultaneously proves provenance and detects tampering, addressing a gap where existing robust watermarks paradoxically enable attackers to modify content while maintaining false attribution. The approach uses complementary signals within the same watermarking mechanism to provide both protections.
