Application and development of block chain technology in health field / 中华医学图书情报杂志

ABSTRACT

Block chain, as a decentralized, trustless database technology program with an intact information trans-parency and a privacy protection function, can be use to construct a highly effective and reliable transmission sys-tem and promote the Internet to become an infrastructure in building the society-trusted network. Block chain is of significant advantages in optimizing the business processes, reducing the operation cost and improving the synergis-tic efficiency in financial industry, and is thus rapidly applied in other industries. The construction of health and medical big data is faced with the challenge of both information security and privacy protection in health field. Block chain is characterized by high fault tolerance, unaltered infrastructure and privacy protection function, and has thus a large room for its application in medical treatment, pharmaceutical industry, medical insurance and ge-nomics.
