Hi:Health is a global ecosystem analyst based on artificial intelligence. The personal ecosystem for diagnosing a human body in real time. Applying medical reports of great amount of patients, and also indicators of health-control gadgets, we teach artificial intelligence to ensure early diagnosis of different illnesses and determine previously unidentified cause-and-effect relationship between functioning of body organs and systems of the body and outbreak of diseases. AI will be able to analyze slightest deviations, which human can’t notice, and also to get more accurate survey results (for example, electrocardiogram) resulting from clearing devices of noise. Also with the help of Al it would be possible to monitor effectiveness of treating in real time and correct doctor's prescriptions. Primarily, Hi:Health will work with early detection of those diseases, increasing of which concerns WHO and other international organizations throughout the world that deal with health issues. It’s about cardiovascular diseases (including coronary heart disease and hypertension which often are the cause of infarctions and insults), asthma. To get a better insight into diagnostics we will use gadgets and mobile applications for survey-taking in real time, quite similar to ECG. Apart from it, we are in the process of collecting data according to DNA testing. It will help to ensure early diagnosis of prospective parents, including testing for their compatibility, undertake more detailed planning towards pregnancy, to recognize the chances of hallmarks of the hereditary diseases. And all this will be possible not during the intrauterine diagnosis, but during the preparatory stage of the conception. In order to verify users, to provide medical confidentiality, for safe storage of data, transfer of information between a doctor and a patient, and also for testing the authenticity of diagnostic gadgets, Blockchain – Ethereum and decentralized file-sharing service Ethereum swarm will be used. HIH token is a Ethereum-token, which can be accepted as a mean of payment during paying for medical services, medical equipment (gadgets) that is connected to HI:Health ecosystem. And also you can make money on your personal health. All users who are already in HI:Health ecosystem undertake to take HIH token during the payment for any of the health services rendered by physicians, during purchasing medical equipment (gadgets), when a patient recourses.
