It proposes an on-premise AI assistant built on Retrieval-Augmented Generation (RAG) and LangChain, dynamically retrieving multimodal electronic evidence from a local vector database. LangChain modular pipelines enable secure control over knowledge linking. Experiments across 30 specialized tasks show higher overall performance, and multi-layer encryption supports judicial data privacy compliance.","cbCaiqnujdJxjrEO","https://ap.wps.com/l/cbCaiqnujdJxjrEO","pdf",783939,1,7,"English","# Introduction\n# Literature Review\n# Methodology and System Design\n## RAG-LangChain Forensic Assistant Architecture\n# Experiments and Evaluation\n# Conclusion and Future Work","[{\"question\":\"What problem does the RAG-LangChain fusion system target in digital forensics?\",\"answer\":\"It targets traditional tool inefficiency and large-model limitations in adapting to domain-specific queries and processing sensitive local data for real-time, personalized retrieval.\"},{\"question\":\"How does the proposed assistant handle multimodal electronic evidence securely on-premise?\",\"answer\":\"It uses RAG to retrieve text, images, and documents from a local vector database, while LangChain provides a modular pipeline with secure control.
