Golden Rock: A Cognitive Authentication Framework for AI-Generated Content

Abstract. The proliferation of generative models has shifted the central question of media integrity from whether synthetic artefacts can be produced to whether observed artefacts can be trusted. We introduce Golden Rock, a cognitive authentication framework that evaluates AI-generated content through a multi-stage cognitive pipeline and returns explainable, auditable verdicts rather than an opaque classifier score. We describe the threat model, the pipeline architecture, and an evaluation methodology oriented toward provenance recovery, structural consistency, and human auditability.

1. Introduction

Contemporary detection systems typically reduce authenticity to a single scalar produced by a discriminative classifier. Such systems are brittle under distribution shift, offer little recourse to a human reviewer, and degrade rapidly as generative models improve. We argue that authentication should be treated not as a binary classification problem but as an act of cognition: a structured process of perception, hypothesis formation, and justification.

2. Threat Model

We consider an adversary with access to state-of-the-art generative models for image, video, audio, and text, capable of post-hoc editing intended to defeat naive detectors. The defender requires not merely a decision but a defensible rationale — evidence that can be inspected, contested, and retained for audit.

3. The Golden Rock Pipeline

Golden Rock composes several cognitive stages. A perception stage extracts multi-modal features and provenance signals; a reasoning stage forms and tests competing hypotheses about the artefact’s origin; and a metacognitive stage estimates its own confidence and abstains when the evidence is insufficient. Each stage emits intermediate artefacts, so the final verdict is the terminus of a traceable chain rather than an inscrutable output.

4. Explainability and Auditability

The system’s output is an explainable verdict: a decision accompanied by the signals that supported it, the hypotheses that were considered, and a calibrated confidence. This design prioritises auditability and aligns with emerging content-provenance standards [3] and with the broader position that trustworthy systems must expose their reasoning.

5. Evaluation Methodology

We evaluate along three axes: provenance recovery, robustness under adversarial editing, and the quality of human-auditable explanations. We contend that reporting a single accuracy figure is insufficient; a cognitive authenticator must be judged partly on whether its justifications enable correct human decisions.

6. Limitations and Future Work

Cognitive authentication inherits the open-world difficulty of all detection: no system is complete against an unbounded adversary. Golden Rock is therefore designed to abstain rather than guess, and to improve continuously as new generative modalities emerge. Future work extends the framework to real-time streams and to cross-modal consistency checking.
