MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611106906 A) filed by Panipat Institute Of Engineering And Technology Piet on September 04, 2026, for A Blockchain-Authenticated Quantum-Safe Digital Twin Healthcare System.
Inventors include Mr. Anurag Vashist; and Dr. Sakshi Patni.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: 046] A blockchain-authenticated quantum-safe digital twin healthcare system is disclosed for secure, patient-controlled sharing of healthcare and digital twin data among multiple authorized healthcare providers. The system comprises a patient-side interface, a healthcare digital twin, provider systems, a permissioned blockchain network, smart-contract logic, an off-chain healthcare data repository, an integrity-verification module, and a quantum-safe communication layer. Following strong patient authentication, a time-limited and revocable cross-provider access token is generated according to patient consent. A requesting provider is independently verified for credential status, role, token validity, consent, purpose, and requested data scope. Upon successful verification, a provider-specific quantum-safe session key is established. Healthcare data remain off-chain, while hashes, consent references, access events, timestamps, and revocation information are recorded on the blockchain. Integrity is verified by comparing off-chain data hashes with blockchain-recorded hashes, and normal or emergency access events are recorded in tamper- evident audit records.
