Securing Healthcare Data in Blockchain Using TSE Algorithm

Received Date:19 July 2023, Accepted Date:29 September 2023, Published Date:17 November 2023


Objective: The main objective of this work is to create a novel patient-centered management system that uses the two-stage encryption TSE algorithm to secure a private blockchain-based healthcare system while providing users with the highest privacy, complete control, and security over their sensitive data. Methods: TSE Encryption Process: The user or the patient asymmetrically encrypts the data's symmetric key using the public key of the party with whom the data is to be shared. TSE Decryption Process: The party wishing to access the health data initially selects the user (patient), then sends the private key to decrypt the data present in the network. The public key of the user is used to verify the signature, and finally, the confidential data is retrieved back to be accessed by the party intended to see it. The TSE algorithm is compared to the DES (Data Encryption Standard) and MD5 (Message Digest Method 5) algorithms, and the results show that the proposed algorithm performed significantly better than the other two. Finding: In this work, the asset is encrypted and indexed in a database, and the asset's value or data is encrypted and stored on a private blockchain to provide the best possible privacy and security. The concept makes use of the immutability, cryptography, and distribution aspects of the blockchain but overlooks the blockchain's public nature and the conventional mining process. Novelty: Most existing approaches store all of the data in the blockchain, which reduces user privacy. The proposed algorithm uses the blockchain to store the index of the health care asset.
