Architecting Guardian-AI: Multi-Layered Content Integrity Filters for Autonomous Publishing

How I Built a Defensive Content Pipeline to Safeguard AI-Generated Media Against Misinformation and Adversarial Injections TL;DR In my experiments with autonomous publishing, I discovered that LLMs, while powerful, are highly susceptible to adversarial injections and factual hallucinations. To solve this, I designed Guardian-AI—a multi-layered filter swarm that audits content through four distinct integrity layers: Injection Detection, Fact-Checking, Plagiarism Auditing, and Ethics Compliance. This experimental PoC demonstrates how a sequential defense-in-depth strategy can significantly harden AI-generated workflows against sophisticated attacks. Introduction From my experience, the transition from 'AI as a tool' to 'AI as an autonomous publisher' is fraught with hidden risks that most organizations aren't prepared for. I observed that simply asking an LLM to 'be safe' isn't enough; adaptive paraphrasing and adversarial prompt attacks can easily bypass single-layer system prompts. I w
