Idea
De-identification platform delivering accurate, locally deployable clinical text anonymization for secure enterprise EHR use.
Research Paper
Core Innovation
This paper presents SHIELD, a novel dataset with diverse, human-annotated clinical notes and distilled small language models that match large model performance on structured PHI categories. It uniquely combines semantic diversity with local deployment feasibility, overcoming cloud dependency and outdated benchmarks.
Why It Matters
Healthcare organizations must protect patient privacy while enabling secondary use of clinical data. SHIELD reduces reliance on costly cloud APIs and addresses limitations of outdated benchmarks by providing a diverse dataset and efficient models that run on standard hardware. This improves compliance, lowers costs, and accelerates data-driven healthcare innovation at scale.
Market Size (TAM)
$2–10B TAM for clinical data de-identification; $500M–$1B SAM from hospitals and health IT vendors. Driven by regulatory compliance and growing EHR data use.
