Leveraging Block Chain for Ensuring Trust in IoT in Health Care

Abstract

Internet of Things (IoT) devices has completely new challenges regarding security and privacy. Blockchain technology could be a great to mitigate challenges of data security and privacy relay in the IoT. Crypto currency networks like Bit coin, can prove to be required towards understanding concept of decentralized, security and Leveraging of blockchain for privacy preserving. Differential privacy is a mathematical technique of adding a controlled amount of randomized noise to a dataset to prevent anyone from getting information about individuals in the dataset. The added randomized noise is in controlled manner. Therefore, the resultant dataset is still accurate enough to generate aggregate output while maintaining the privacy of individual participants. As Block chain is a peer-to-peer distributed ledger, it is an optimal way for preventing identity, monitoring, non-repudiation and providing tracking in IoT, so due to these aspects we can explore future research challenges to preserve privacy in blockchain.
