Protect patients' privacy and prevent the proliferation of counterfeit drugs -- blockchain builds a strong defense line for the medical industry and the world tide of scientific and technological innovation

        In the real world, novel coronavirus is still raging, and there is another different "epidemic" on the virtual network & mdash& mdash; Network attack. In the past few years, the number of cyber attacks has increased significantly and has become a daily reality that the healthcare industry has to deal with. According to a recent report on the Forbes biweekly website, blockchain technology is expected to "escort" the medical industry and completely change the industry with its characteristics of decentralization, openness, transparency, traceability and non tampering. In 2021, the hospital network security vulnerability reached a record high, and 45 million people were affected by medical network attacks, an increase of 11 million over 2020.
        In addition, since 2018, the number of cyber attacks against medical institutions has tripled, and has also been extended to other medical fields. From 2020 to 2021, attacks against health programs increased by 35%; Attacks against third-party vendors increased by 18%. In 2022, there is still no sign of a slowdown in cyber attacks against the medical sector. In April this year, the US Department of health and human services issued a warning to blackmail groups that launched attacks against the medical ecosystem. These attacks may lead to various consequences: hospitals have to stop operation, non emergency patients are transferred, patient privacy is leaked, medical infrastructure is damaged, and so on.
        Medical data leakage accounts for 15% of global data leakage events and has become the second largest field of global data leakage. In the autumn of 2020, nearly a month after blackmail software closed access to electronic health records and other systems, the cancer center of the University of Vermont medical center had to refuse hundreds of chemotherapy patients. In addition, according to a recent report of the bonamont Institute of the security research center, in the past two years, 43% of the surveyed health care providers were attacked by extortion software. The consequences include poor results due to program or test delays (70% of the hospitals affected by extortion software have experienced), increased medical surgical complications (36%), and increased mortality (22%).
        Blockchain is a security technology for tracking transactions. It is essentially a digital ledger, encrypting information or data "blocks" and linking these information together to create a single real source. In short, blockchain is a decentralized distributed ledger database. According to the European Radiological Society, "blockchain technology is likely to become a breakthrough technology in the next few decades. It is a cross domain technology that can give citizens, public services and enterprises the ability to secure, transparent, verifiable, decentralized and share data access rights.". Health data information security and privacy protection are the most widely used fields of blockchain technology in the medical field.
        The blockchain technology with the characteristics of decentralization and sharing can record the complete health history of individuals, safely share patient data, and make the storage and access records of medical data recorded and non tamperable. This not only ensures the privacy and security of medical data, but also has valuable value for precision treatment and disease prevention, and can conduct health management based on patient data. In addition, the traceability characteristics of the blockchain make it possible to trace and supervise medical accidents and drugs. The instantly updated and widely shared blockchain data enables pharmaceutical manufacturers, pharmacies, buyers, regulatory authorities and other parties to observe the data flow in real time, strengthen drug supervision and prevent counterfeit drugs from entering the market.
        For example, a British company engaged in supply chain management has created a set of anti-counterfeiting solutions by using blockchain technology, so that medicines and luxury goods can be managed in the whole process to prevent fake goods from appearing in any process. Gemhealth, the developer of the US enterprise blockchain application platform, and "first capital" bank will jointly develop a blockchain based health care claim management solution to effectively prevent malpractices such as insurance fraud and reduce the waste of medical resources. Anthem, the second largest medical insurance company in the United States, has also started to use blockchain technology to help patients safely access and share their medical data. First, it is well known that the field of health care has made slow progress in adopting new technologies.
        In order to make better use of blockchain technology, the medical industry needs to change its operation process and infrastructure. For an industry that is still trying to exchange information electronically and use distributed information technology systems, turning to the implementation of blockchain will be an important step. Secondly, blockchain is a brand-new technology. The medical industry needs to develop payment applications using blockchain technology to build infrastructure from scratch. Once blockchain technology becomes more user-friendly, it can be widely adopted. Although blockchain technology seems daunting, it has great potential to change the medical industry by providing higher security, transparency and integrity.
        According to market research institutions, in recent years, the demand for blockchain technology in healthcare has been increasing. In response to the digital trend, the global blockchain healthcare industry market value will reach more than US $1.7 billion by 2026, with an average annual compound growth rate of 48.1%.
