Survey Paper on Secure Healthcare System Using Blockchain Technology

In today’s life healthcare security is most important issue. In block-chain technology, each page in a ledger of healthcare data forms a block. That block has an effect on the next block or page through cryptographic hashing. In other words, when a block is completed, it creates a unique secure code, which ties into the next page or block, creating a chain of blocks, or block-chain. In proposed system data will be of Medical data need to secure. This work is designed using block chain concept and key-based cryptographic technique. Stores the hash tables of raw data and files on the block-chain, validates other copies by running a hashing technique, and then compares the data stored in the block-chain, any interfere with the data will be quickly found, because the original hash Tables are stored on millions of nodes. Proposed system work on storing data of healthcare data. This system will work on consensus mechanism while adding data in block chain. This system will find malicious user’s and inform to owner.
