Intelligent printing content identification and security risk control method and system

Abstract

This invention discloses an intelligent document content recognition and security risk control method, comprising the following steps: S1, receiving printed and copied documents through a unified intelligent entry point; S2, performing comprehensive and multi-level analysis on the uploaded documents to extract structured information and semantic features; S3, before printing / copying, conducting real-time security risk assessment on the extracted structured information and semantic features based on a preset three-layer security policy library, and executing a tiered response strategy according to the assessment results; S4, establishing a full-text index for the processed document content, while recording document metadata to construct intelligent retrieval and auditing. This invention achieves deep perception and understanding of printed document content, laying the foundation for advanced applications. It establishes a proactive security risk prevention and control mechanism to prevent information leakage at the source.
