Detection & Attribution

Scope

Separate generated-versus-captured classification, model-family association, exact deployment identification, account linkage, and human attribution. A style resemblance or a model’s own statement about its identity is insufficient for exact identification.

Questions worth testing

• Does the test allow an unknown source?
• How often are unrelated sources wrongly attributed?
• Does the association survive realistic transformations?

Evidence and study material

Known-source controls, generation records, model configuration, deployment logs, content measurements, and independent account or task records can support different levels of attribution. Keep claimed source labels separate from verified labels.

Methods to begin with

• attribution
• ai detection limitations
• confidence

Limits on interpretation

Closed-set accuracy can hide open-set errors. Unknown generators, deployment drift, and post-processing weaken transfer from a benchmark to a case object. Shared model ancestry can further complicate family-level attribution.

Open research questions

Open problems include unknown-source rejection, cross-model transfer, score calibration, and reporting false attribution costs. Evaluation needs a held-out set of genuinely different sources and a stated decision rule.

Tools, projects, datasets, and publication

Consult the detection-limits guide before selecting a tool. No model classifier or attribution benchmark is supplied by this project. SFIF validation stages can structure a study for a Journal replication.

What happens when the true source is not a candidate?

Include unknown-source material in an attribution test. Compare the method’s willingness to reject unsupported candidates with its accuracy on known sources. Test relevant transformations and state which level of source identity the labels represent.

A classifier that always selects one listed model cannot demonstrate reliable rejection of unlisted models. Report that boundary and avoid translating a forced choice into certain identification of a historical source.
