Improving Healthcare Applications Security Using Blockchain

Nowadays, the Internet of Medical Things (IoMT) technology is growing and leading revolution in global healthcare field. Exchanged information through IoMT permits attackers to hack or modify patient’s data. Hence, it critical importance ensure security privacy this information. The standard techniques are not secured enough, so paper introduces blockchain that used for securing Blockchain with smart contract secure private patient records. This presents how a may send his vital signs physician without meeting latter person. These collected from system we developed before. In proposed method, each medical record stored block connected previous by hashing function. order new block, SHA256 algorithm used. We modified using run-length code compressing If any hacker attempts attack record, he must change all blocks. preserve rights doctor patient, built into system. When transaction begins, withdraws money wallet stores contract. sends treatment transfers physician. shows recent work implements 2 also our can create O (n + d) time complexity. As result, one hundred blocks two minutes. Additionally, deposit physician’s promptly. method performs better than subsequent versions original blockchain.
