via “local-pii-anonymization-before-llm-transmission”
A zero-trust SDK for anonymizing PII locally before sending prompts to LLMs and seamlessly rehydrating the response.
Unique: Implements client-side anonymization with zero transmission of raw PII to external services, using deterministic token mapping that enables perfect rehydration without storing plaintext on remote servers. Combines regex-based pattern matching with optional NER integration for context-aware detection, all executed locally before API calls.
vs others: Unlike cloud-based PII masking services (e.g., AWS Macie, Azure Purview) that require uploading data for scanning, rehydra performs all detection and anonymization locally, eliminating the trust boundary problem and reducing latency by avoiding round-trip API calls.
