Discover LLM Text Watermarks with WMTrace
Analyze the source and watermarks of AI-generated texts.
1What is WMTrace?
WMTrace is a tool designed to detect watermarks, provenance signals, and hidden payloads in AI-generated texts. It analyzes whether texts carry a specific watermark scheme, key, and configuration. Each result clearly states what the evidence does not prove.
2How Does It Work?
WMTrace offers a web interface that allows users to analyze texts. This interface automatically loads and analyzes watermarked samples. Users can also scan texts by selecting a specific watermark scheme and receive full evidence bundles in JSON format.
3Watermark Schemes
WMTrace supports various watermark schemes. For example, it can analyze contextual green-list (KGW-style) and fixed keyed green-list schemes. Each scheme requires a specific key and configuration, and the evidence for these schemes is presented with categorical grades (E0-E5).
4Evidence Bundles
WMTrace presents analysis results as evidence bundles. These bundles include categorical grades and mandatory scope statements. For instance, E0 grade indicates that the required key or configuration is unavailable, while E3 grade shows calibrated evidence for a specific scheme.
5Detectors and Statistics
WMTrace ensures that each detector implements a five-method plugin contract. The shared statistics layer manages significance tests, and no detector creates its own statistics. This ensures that analyses are consistent and reliable.
6Use Cases
WMTrace can be used to verify the source of AI-generated texts. For example, it can check if a text carries a specific watermark scheme or detect hidden payloads. This enhances the reliability of texts.
7Future Plans
WMTrace plans to add features like model-based detectors, C2PA verification, and provider adapters. These features will expand the tool's capabilities and allow users to perform more comprehensive analyses.
8Why It Matters
WMTrace is an essential tool for verifying the source and reliability of AI-generated texts. This plays a critical role in the legal and ethical use of texts. It also helps prevent text manipulation.
