Methodology Overview
FABench Dataset
Agentic Tool Use
ForenAgent employs a novel interactive multi-turn framework enabling MLLMs to autonomously generate, execute, and iteratively refine Python-based low-level tools for Image Forgery Detection (IFD). The approach integrates both low-level forensic analysis and high-level semantic reasoning, addressing key challenges in current IFD systems.

ForenAgent's core innovation is its ability to autonomously compose Python toolchains for forensic analysis. It utilizes a toolbox of 12 low-level forensic methods, dynamically selecting and applying them based on the task.
Example: Synthetic Image Identification
In one case, ForenAgent successfully identified a synthetic image by applying a DCT-based global screening, followed by local focusing and iterative probing with JPEG Ghost and Bayar Constrained Convolution. The agent integrated all cues to provide a well-founded decision, demonstrating logical, tool-driven forensic rationale. This highlights ForenAgent's ability to not only produce correct labels but also assemble a logically sound, tool-driven forensic rationale, charting a promising path toward general-purpose IFD.
Key Benefit: Generates interpretable and systematic forensic reasoning paths.
Outcome: Accurate detection and explanation of synthetic content.

Your ForenAgent Implementation Roadmap
A structured approach to integrating advanced AI forensics into your enterprise operations.
Phase 1: Cold Start Training
ForenAgent adopts a self-exploration and experience-distillation paradigm, observing large collections of forgery samples under system prompts to distill operational patterns into structured agent-interaction data.
Phase 2: Reinforcement Fine-Tuning (RFT)
MLLMs acquire tool-calling and reasoning using pure RL. A dynamic reasoning loop (global perception, local focusing, iterative probing, holistic adjudication) is formulated as data-sampling strategy and task-aligned process reward.
Phase 3: Deployment & Monitoring
Integrate ForenAgent into existing workflows for real-time image forgery detection. Continuously monitor performance and retrain with new data to adapt to evolving manipulation techniques.
