Healthcare Blockchain
Operating System

phrOS, a revolutionary blockchain operating system, is specially designed for the healthcare industry. By integrating the blockchain technology and using the distributed database architecture, the system allows hospitals, care providers, medical device developers, App developers, financial companies and big data analysts to jointly create ecosystem applications for areas such as personal health records, data lakes, disease prediction and monitoring, precision medicine R&D, automatic insurance reimbursement, online health management, long-distance care, clinical data analysis, etc.

Vision

● To allow everyone in the society to enjoy the healthcare blockchain services and own personal health records which can be accessed worldwide so as to create a healthy and civilized new society.
● To allow every doctor and researcher to make medical advance by using blockchain services and data lakes.
● To solve the problem of privacy, data security and interoperability, and to promote healthcare industry collaboration.

Solutions


phrOS Super Node

phrOS is an integrated operating system with development tools specially designed for the healthcare industry. phrOS resolves the problems of privacy protection, data security and interoperability. By using phrOS, healthcare providers can easily and quickly develop and manage a distributed data lake and vast personal health records. Companies often find it very challenging to build up and maintain their own blockchain-based services. phrOS provides flexible and adaptable technology options so that companies can just focus on the development of their business models.

phrOS provides a platform featuring IoT ready, cross-chain and multi-nodes management. It integrates smart contracts with distributed storage technology, keys with data wallet management, transaction monitoring with client notification, etc. By using the open-source and permissioned blockchain structure, phrOS ensures the autonomy of all participants and developers, and sustains industrial collaboration.


phrOS API Server

phrOS API Server features speedy development of RESTful API, SDK, integrated application software, smart contracts for healthcare and blockchain services.


phrOS Client

phrOS Client is designed for the IoT hardware, such as identity authentication, wearable devices, small medical equipment, etc. It achieves equipment autonomy as no cloud or central server is required.


phrOS Light

phrOS Light is a lightweight node specially designed for small healthcare providers without requiring IT management. It integrates IoT gateways and supports service load distribution and node expansion.


phrOS Smart Contract

phrOS Smart Contract supports the use of smart contract codes in the blockchain, such as patients’ consent forms and automatic insurance reimbursement. As no cloud or central server is required, it simplifies the management and reduces the maintenance cost.

Technical Advantages

The hybrid blockchain platform is tailor-made for the healthcare industry


Blockchain integration tools

This platform has features of hierarchical account framework, the issuance and management of security keys and cross-blockchains (including public chains and private chains). Hence, developers can concentrate on the development of their business models without worrying about the underlying technology or being restricted by the lack of it, while keeping the R&D cost and maintenance cost to the minimum.


Identity authentication and identification

The platform provides identity links for participants in the healthcare ecosystem, such as hospitals, doctors, patients, nurses, IoT hardware, etc. It also performs the issuance and management of permits, authentication, revocation, electronic signature, annotation, etc.


Distributed data lake

Personal health records require the highest degree of privacy protection and data security. phrOS supports the distributed data lake within the blockchain framework. Every record is electronically signed and dated, and its ownership and data source are verifiable. These features make phrOS the best solution for keeping health records. It gives hospitals and research institutes the capacity to establish complete and high quality dataset and to fully unleash the power of the data.


Smart Contracts

Smart contracts are computer protocols embedded on the Internet. They can be used for all kinds of contractual clauses, including retrieval and storage controls, automatic capital flow, etc. The program is self-executing when triggered by events, and works independently from any computer environment. The applications include the management of healthcare resources, the provision of value-added healthcare services, automatic insurance reimbursement, etc.


Prompt and highly expandable

Permissioned blockchain can operate without mining as it is based on DPOS and PBFT. Hence, transactions can be done immediately without wasting any time on confirmation.


Standard API development environment

phrOS provides RESTful API for software engineers’ quick integration and application without requiring the knowledge of detailed blockchain technology. It speeds up the development and testing processes.

Data Security, Privacy Protection and Interoperability

The blockchain technology is the best solution to the protection and security of the healthcare information. phrOS creates a permissioned blockchain. Its distributed structure protects the system from single-point attack or malfunction, supports distributed storage and prevents data catastrophes. All personal health records are stored in personal encrypted security accounts. The keys are kept by patients themselves or by delegates authorized by patients. As no nodes in the blockchain alliance are linked to any centralized dataset or passwords, it significantly increases data security.


Centralised


Decentralised


Distributed


Using de-identified ID, patients can connect to healthcare service devices via the blockchain. All data will be encrypted when stored, and can only be accessed by the account owners who hold the keys or by their authorized delegates. It gives the highest level of the privacy protection.
As the blockchain is a trusted network, all participants in the network (including IoT equipment) can carry out point-to-point information exchange without requiring any third party as a trusted mechanism. This is the ultimate solution for data portability and interoperability.

Use Cases


Hospitals

  • Create the blockchain accounts for patients and access health records through their accounts.
  • Develop health management software to provide online service for patients or for other healthcare providers through authorization.
  • Develop data lakes, big data and AI applications so that doctors can improve medical benefits through AI and experiences with data.
  • Strengthen the information link between hospitals and district clinics so as to share information and develop value-added business models.
  • Doctors can submit healthcare resource requirements and the request for proposal (RFP) through the joint network of the blockchain.

Health Centers

  • Increase the portability of health reports, and link to data supplied by patients.
  • Create a close link between health centers, hospitals and GPs to form a network for disease prevention and collaboration, and to provide follow-up health monitoring services.

Biopharmaceutical industry

  • Access big data for researches with prior consents from patients or hospitals.
  • Track clinical data more timely and accurately.
  • Store personal genetic information safely in distributed personal storage space.

Financial and insurance companies

  • Carry out automatic insurance reimbursement without requiring patients to provide paper documents.
  • Provide accurate, quick and tailor-made online insurance services.

Healthcare IoT companies

  • Directly link medical devices, such as blood glucose monitors and wearable devices, to patients’ accounts. Tests results will be exported to users. All devices are interoperable without requiring centralized cloud service. Companies can develop applications by using the smart contract services without going through the hassle of integration.
