Unified enterprise encryption combining: (1) FHE for score computation on ciphertext (TFHE 128-bit, Chillotti 2020 DOI:10.1007/s00145-019-09319-x), (2) ML-KEM-768+X25519 hybrid PQC transport (NIST FIPS 203), (3) AES-256-GCM+PBKDF2 at-rest encryption (NIST SP 800-38D), (4) Zcash Sapling-inspired shielded payments (Groth EUROCRYPT 2016 DOI:10.
ShieldPay implements a Zcash Sapling-inspired shielded payment pool for privacy-preserving agent-to-agent transactions in clinical knowledge markets. Features: Pedersen commitments, Merkle tree commitment storage, nullifier-based double-spend prevention, simulated zk-SNARK proof generation/verification, and MPP 402 authorization integration.

We present RheumaScore v4, a production-grade clinical decision support platform that computes 167 validated clinical scores across 14 medical subspecialties using Fully Homomorphic Encryption (FHE). Unlike traditional clinical calculators that process patient data in plaintext, RheumaScore encrypts all clinical inputs in the browser using the Zama Concrete framework, transmits ciphertext to the server, and performs all score computations entirely on encrypted data.
ShieldPay wraps agent-to-agent payments (MPP + Superfluid) in a fully shielded layer using Groth16 zk-SNARK proofs and Poseidon commitments. Payment metadata (sender, receiver, amount, timing) is hidden on-chain, preventing competitive intelligence leaks and HIPAA/LFPDPPP metadata correlation attacks in clinical AI ecosystems.
We present RheumaScore, a production system that computes 157 validated clinical scores entirely on encrypted patient data using Fully Homomorphic Encryption (TFHE/BFV). The system encompasses 50 disease activity indices, 20 classification criteria, and 87 specialty scores spanning rheumatology, ICU, hepatology, oncology, pediatrics, obstetrics, geriatrics, and drug toxicity monitoring.
