APPLICATION SCENARIO

Personal Health Management provides for health education, health assessment, health promotion, and health tracking by performing data analysis of personal lifestyle choices, personal medical history, personal health check-ups, etc. Specialised health management services, such as supervision and medical consultation are also possible. Shelter Chain has a distributed database that allows personal comprehensive health information to be accessed by medical service providers and health service providers, allowing patients to benefit from more complete, more accurate, and safer data services, and ultimately improving quality across the board by providing better personal health management services. Simultaneously, the intelligent guided diagnosis platform implemented by Shelter Chain will allow users to assess their medical problems. 
Medical data is currently held "island-style" in centralised storage in most places, making it difficult to share securely. Health insurance-related claims are still at the stage of relying on paper documents, reducing both efficiency and accuracy. Using Shelter Chain, data on medical equipment, medicines, and medical personnel will be perfectly linked to the chain; any available information will be saved to the chain, and the best configuration will also be obtained in each case. Medical staff and users can choose the data with the highest utilisation value to go on the chain, connecting their medical data islands, and promoting regional interoperability. 
In the current insurance business, the lack of reliable means of data collection and storage of personal information means that disputes between the insurance company and insured parties often occur, particularly where the insured party provides false or incomplete information. Where personal information is lacking, when a claim is settled, there may be disagreement on the determination of any exemption clauses, for example. Insurance companies face various risks from time to time, and any regulatory agency can only take pre-examination or post-restraint measures. 
For other medical insurance institutions, Shelter Chain can be used to assist from the perspective of data management, effectively helping insurance companies improve their risk management capabilities, to improve risk management for policyholders and risk supervision for the companies. For allied medical insurance institutions, the Shelter Foundation and the Shelter Chain project profits will provide sufficient funds for claims settlement, and Shelter Chain (SHC) users can enjoy the benefits of shelter chain medical insurance, including 60 to 70% of claims, unlimited borders, and prompt payment. 
The development of new drugs can be used as an example. According to the 2016 Journal of Health Economics, it takes more than 10 years and 2.6 billion yuan for a pharmaceutical company to market a drug, though the cost, effort and time required for drug development are difficult to estimate. Many of these costs are exacerbated due to the high administrative costs of distributed multi-agency administrative supervision and clinical trial data collection. The use of Shelter Chain can help scientific research institutions and scientific researchers to conveniently and reliably manage the experimental results from multiple test sites and multiple test patients, reducing the cost of multi-centre test methods. 
As sensitive data such as personal medical information are scattered across various medical institutions, urban and rural medical industries in different regions are very suitable application scenarios for blockchain technology. The blockchain can be used to realise the circulation and authorisation of residents' health information so that doctors at various levels of hospitals in various regions can quickly understand a patient's past medical history and access medical examination information when they are authorised to do so, avoiding unnecessary secondary examinations and saving on medical payments. This improved access to full medical services should thus help global medical reform. Shelter Chain will invest in urban and rural medical development, simplifying medical assistance and standardising the workflow of urban and rural medical services to improve the management of intelligent medical assistance services.
