Tokenized Key-Gated Adapter Routing: A Secure Access Control Mechanism Against Private Data Leakage in LLMs
Researchers introduce tokenized key-gated adapter routing to prevent LLMs from leaking memorised PII—a pattern with direct implications for GDPR-compliant AI deployments in healthcare, finance, and government.

arXiv:2610.00309v1 Announce Type: new Abstract: Large language models (LLMs) are increasingly deployed in privacy-critical domains (e.g., healthcare, finance, and government), but their propensity to memorize and disclose personally identifiable information (PII) poses serious security and compliance risks. Existing defenses typically force a trade-off between model utility, privacy protection, and access to fine-tuned private knowledge. We propose LoRA-Oriented Control via Keyed Entry Tokens (
Editorial Analysis
LLMs deployed in privacy-sensitive sectors risk leaking memorised personal data; access-control mechanisms at the model layer could become a compliance expectation under GDPR and the EU AI Act.
Add LLM memorisation and PII disclosure to your AI risk register and evaluate architectural mitigations like adapter-level access gating.
A new technical control could help prevent LLMs from leaking personal data, addressing a growing regulatory and reputational risk.
