Secure Document Screening & Summarization Workflow

Secure Document Screening & Summarization Workflow

Protect your sensitive data with our cutting-edge n8n Secure Document Screening & Summarization Workflow. Automatically screen documents for HIPAA, GDPR, and PCI compliance, and detect prompt-injection threats with seamless integration. Clean documents continue to Anthropic Claude for summarization, while questionable entries are flagged, ensuring robust data security every time.

What this workflow does

• Receives data via a POST request to a webhook, handling either a PDF upload or a JSON body with a `text` field.
• Extracts text from PDFs, or utilizes JSON text directly when provided.
• Dispatches document text to PromptLock Guard for risk assessment, focusing on regulated-data security and prompt-injection risks. Any errors during screening halt further processing for safety.
• Allows or redacts approved documents, forwarding them to Anthropic Claude for a structured JSON summation response.
• Sends flagged documents for human review through a Gmail notification, bypassing AI model analysis.
• Blocks unsafe documents, providing a JSON webhook response with block/unverified reasoning.
• Logs document processing details in a Google Sheets `DocAuditLog`, ensuring transparency with an audit trail.

Use cases

• Ideal for organizations that need to process large volumes of contracts, intake forms, and reports while ensuring compliance with major data protection regulations.
• Perfect for SaaS operators who must safeguard against prompt-injection threats in document workflows.
• Suitable for automation engineers looking to streamline document processing while maintaining stringent security checks.

Technical details

• Key integrations include PromptLock Guard for data screening and Anthropic Claude for document summarization.
• Utilizes nodes such as if, set, Gmail, webhook, sticky note, and HTTP request within the n8n platform.
• Requires setup of n8n-nodes-promptlock-guard community node, PromptLock API key, Anthropic API credentials, and Gmail OAuth2 credentials.
