Integration of Blockchain in WBAN

In today modern digital world, there is huge need of security in medical field also. Among all modern data transfer techniques, Blockchain is a fast growing technology which provide a cryptodata through which we can transfer data between peer-to -peer node. Blockchain provide security which depends on highly cryptographic schemes. We can integrate blockchain with wireless body area network. Because WBAN is also a very emerging field of medical department. All the data of patient is maintained in a electronic health record (EHR). So Maintaining a EHR is very challenging face of medical field. In WBAN we transfer the patients data among different entities like healthcare server, medical staff, health insurer over the network. So we can provide security in this field through blockchain. In this paper we propose an architectural model of block chain with WBAN. We also mention some challenges which are faced in the field of medical health care applications.
