Using Fragment-Level Provenance to Prevent and Recover from AI Misinformation
17.1 Introduction: Poison at the Memory Layer
As retrieval-based AI systems dominate knowledge delivery, they introduce a new surface of risk:
Data poisoning at ingestion scale.
Whether it’s misinformation, emergent bias, misaligned definitions, or adversarial prompt influence—poisoned knowledge embeds deep into model memory, where it silently contaminates generative output.
Most AI systems try to detect poison after it surfaces.
WebMEM prevents poison from surviving ingestion.
17.2 The Limits of Internal Detection
Even with anomaly classifiers, adversarial filters, and red teaming, LLMs can’t fully detect memory poisoning internally.
Why?
- Poisoned facts can mimic source tone
- Incorrect definitions can become dominant through reinforcement
- Hallucinated trust signals can pass unnoticed
Traditional AI defenses scan output.
WebMEM guards the memory layer itself—before hallucination happens.
17.3 Externalized Trust via ProvenanceBlock
WebMEM uses Semantic Digests that include a ProvenanceBlock—a machine-verifiable trust layer embedded in every fragment.
It includes:
prov:wasDerivedFrom
— Source dataset or publicationdcat:license
— Usage permissionstrust_layer
— Confidence level or review statusdata-confidence
— Optional scoreprov:generatedAtTime
— Timestamp of derivationretrieval_format
— Output method (JSON-LD, TTL, Markdown, etc.)
This externalizes trust—from model internals to machine-readable content scaffolds.
AI systems, agents, or validators can independently verify, cite, or reject content based on the attached trust metadata.
17.4 Fragment-Level Trust Immunity
Each field in a digest is modular and annotated with:
data-id
— Unique fragment keyderived-from
— Source file or datasetdefined_term
— Glossary alignmentderived_translation
— Any transformation logicconfidence
— Optional trust score
This structure enables granular fault tolerance.
If one field is poisoned (e.g., wrong MOOP value), the system can flag or suppress that field…
without discarding the entire digest.
This is structured trust immunity—the AI equivalent of selective rollback.
Memory becomes degradable, not destructible.
17.5 Recovery Through Feedback Loops
Most AI poisoning leads to system-wide instability.
WebMEM enables structured recovery via:
- Versioned Digests – New entries can supersede old ones, leaving an audit trail
- TrustScore Decay – Fragment-level retrieval behavior informs when trust is weakening
- Feedback-Based Reconditioning – Retrieval feedback loops (see Part 9) can identify and repair compromised fragments
- Machine-Readable Correction Notices – PROV metadata can log retroactive corrections (e.g.,
prov:invalidatedAtTime
,prov:alternateOf
)
This turns memory from a black box…
Into a declarative trust graph—auditable, updatable, defensible.
17.6 Summary
WebMEM isn’t just about retrievability.
It’s about resilience.
With structured provenance, versioning, and fault-tolerant memory scaffolds, you create:
- Trust zones within memory
- Immunity layers around misinformation
- Recovery paths for poisoned systems
In a world where AI outputs shape real-world decisions, you don’t just need content that can be retrieved.
You need memory that can be trusted, updated, and defended.
