MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641048598 A) filed by Srm Trp Engineering College; and Srm Institute Of Science And Technology, Tiruchirappalli, Tamil Nadu, on April 16, for 'hybrid encryption and merkle-tree integrity verification for blockchain-based medical data storage.'
Inventor(s) include Sendhooran A; and Krishnamoorthy Ramaswamy.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a system and method for secure storage and integrity verification of medical records in a cloud environment. Medical data is encrypted using authenticated symmetric encryption, and the generated session key is protected using asymmetric encryption to enable secure key management. A Merkle-tree-based integrity mechanism is employed to generate a cryptographic integrity root from the encrypted medical data, and the integrity root is recorded on a blockchain ledger. The encrypted medical data is stored off-chain in cloud storage, thereby reducing blockchain storage overhead. During data retrieval, the integrity of the medical data is verified by recomputing the Merkle root and comparing it with the blockchain-stored value. The invention ensures confidentiality, integrity, tamper detection, and scalable storage of medical records suitable for healthcare information systems."
