How Polygraf AI Works
Polygraf operates across several layers depending on the product being used. Consumer tools analyze submitted content for AI generation, source, originality, and writing characteristics. Enterprise security products can intercept AI interactions and inspect them for sensitive information and policy violations.
Typical AI Detection Workflow
- Submit Content — Paste or upload the content to Polygraf.
- Analyze the Content — Polygraf evaluates the submitted material.
- Detect AI Patterns — The system estimates whether content appears AI-generated.
- Analyze the Source — Source detection can attempt to identify the likely AI model or humanizer.
- Generate Results — Polygraf provides detection scores and supporting insights.
- Review the Findings — Users can inspect highlighted passages and additional analysis.
Typical Secure LLM Workflow
- Send an AI Request — A user or application submits a prompt.
- Intercept the Request — Polygraf’s security layer analyzes the interaction.
- Detect Sensitive Data — PII, PHI, PCI, credentials, or other sensitive information is identified.
- Apply Policies — The system can allow, block, flag, or anonymize the request.
- Sanitize the Prompt — Sensitive information can be replaced with protected placeholders.
- Process Through the LLM — The AI model receives the sanitized request.
- Scan the Response — The resulting response can also be checked.
- Restore Protected Information — Where applicable, anonymized information can be restored for the authorized user.
