Existing forensic detectors can target certain forgery types but lack interpretability, while vision-language models (VLMs) provide explanations but cannot exploit forensic traces for reliable detection. We propose Forensic Knowledge Graphs (FKGs), a unified framework that integrates forensic evidence extraction, structured reasoning, and human-interpretable explanation. Our FKG structure encodes forensic traces along with their causal dependencies and links to scene content. To generate accurate FKGs, we introduce a novel forensic authentication network and an Iterative Context Refinement strategy that guides VLMs to produce faithful, grounded explanations. We also present FKG-50K, a dataset of 50,000 realistic forgeries with ground-truth FKGs. Experiments demonstrate that FKG outperforms both forensic detectors and VLMs in detection, forgery identification and localization, and forensic justification.", "url": "https://wpnews.pro/news/trustworthy-image-authentication-using-forensic-knowledge-graphs", "canonical_source": "https://arxiv.org/abs/2606.23917", "published_at": "2026-06-24 04:00:00+00:00", "updated_at": "2026-06-24 04:23:14.654385+00:00", "lang": "en", "topics": ["generative-ai", "computer-vision", "ai-safety", "ai-research"], "entities": ["Forensic Knowledge Graphs", "FKG-50K", "arXiv"], "alternates": {"html": "https://wpnews.pro/news/trustworthy-image-authentication-using-forensic-knowledge-graphs", "markdown": "https://wpnews.pro/news/trustworthy-image-authentication-using-forensic-knowledge-graphs.md", "text": "https://wpnews.pro/news/trustworthy-image-authentication-using-forensic-knowledge-graphs.txt", "jsonld": "https://wpnews.pro/news/trustworthy-image-authentication-using-forensic-knowledge-graphs.jsonld"}}
