Evidencepartial
All methods achieve 100% identifier recovery under benign and sanitization workflows (Tiers 1–2).
Implicationpartial
Explicitly stated in the abstract with clear numeric results.
Verificationpartial
partial
Evidencepartial
The hybrid Mode B maintains 97% through targeted adversarial transforms (Tier 3)
Implicationpartial
Explicitly stated in the abstract with clear numeric results.
Verificationpartial
partial
Evidencepartial
We show that improper layer composition can reduce Tier 3 recovery from 97% to 0% via cross-layer interference
Implicationpartial
Directly stated in the analysis excerpt with specific numeric degradation.
Verificationpartial
partial
Evidencepartial
An end-to-end case study against an LLM-orchestrated ransomware pipeline confirms that both modes detect and block canary-bearing uploads before file encryption begins.
Implicationpartial
Stated in the abstract as confirmed by an end-to-end case study, though specific numeric detection rates for the case study are not provided in the excerpt.
Verificationpartial
partial
Evidencepartial
Current defenses offer limited protection... LLM analysis of documents that have already left the organization’s control.
Implicationpartial
Directly stated as a limitation of current defenses in the introduction.
Verificationpartial
partial
Evidencepartial
We support two modes of operation where Mode A marks existing sensitive documents with layered symbolic encodings... while Mode B generates synthetic canary documents using linguistic steganography
Implicationpartial
Explicitly and clearly described in the abstract.
Verificationpartial
partial
Evidencepartial
AI-powered malware increasingly exploits cloud-hosted generative-AI services and large language models (LLMs) as analysis engines for reconnaissance, file triage, and code generation. Simultaneously, routine enterprise uploads expose sensitive documents to third-party AI vendors. Both threats converge at the AI service ingestion boundary
Implicationpartial
Directly stated as the core problem motivation in the introduction and abstract.
Verificationpartial
partial
Evidencepartial
To our knowledge, this is the first framework to systematically combine symbolic and linguistic text steganography into layered canary documents for detecting unauthorized LLM processing
Implicationpartial
Explicitly claimed as a novel contribution in the abstract, though it is a knowledge claim ('to our knowledge') rather than a directly verifiable result.
