Block Chain Technology towards Identity Management in Health Care Application

Blockchain is decentralized architecture, where data are stored in the form of blocks for processing. The data has to be transferred from one person to another with safety and security and updated with smart contract in the blockchain. But there are some challenges such as data spoofing, integrity, authentication of the data. In the health sector the privacy of the patients' data has to be maintained. The proposed system, “Insurance Management in Healthcare Sector” uses blockchain combined with identity management to access the identity of a person when authorized by the person. After verifying the details, the insured amount will be transferred to the policy holder or the hospital with the help of matching smart contracts in the blockchain of the Ethereum platform. As a result, the insurance claim can reach the policy holder who has initiated the claim process with proof of work. The other use cases such as health care industries, social media networks are also discussed and the analysis of how the blockchain can be used in various fields.
