Privacy preservation of medical data in blockchain with secret key generation using RideNN

Medical equipment and applications produce a significant amount of data. This information is moved from one piece of equipment to another and occasionally shared via a global network. So, privacy preservation and security are important concerns in the medical field. Hence, a new medical data-sharing technique is introduced with blockchain for attaining privacy-preservation. At first, the blockchain system is modelled and then the input data is acquired from the databases, which is forwarded to the patient’s medical data preservation phase. Here, the secret key generation is used to bring privacy to the patient’s medical data using blockchain topology. Thus, the secret key generation is accomplished with the Rider Optimization algorithm-based Neural Network (RideNN). Here, the Rider Tangent Optimization Algorithm (RTOA) is utilized for RideNN training which is named as RideNN-based blockchain. The RTOA is generated by combining the Tangent search algorithm (TSA) and the Rider optimization algorithm (ROA). The RideNN-based blockchain performed better producing augmented privacy of 90.6% and utility of 88.5%.
