We design and develop the PHR infrastructure considering economically sustainable, compliance to regulation in each country and visually understandable/controllable evaluation process and information value and risks.

In this service, we will help you from one specific part to whole architectural design leveraging broad governmental/academic connections to meet your requirements. 


Developing a patient/health-practitioner-centralized PHR

1. Current Situation

  • PHRs (Personal Health Record) in Japan still have not reached the stage of practical use. The major reason is that the medical portion (EHR: Electronic Health Record, a linkage system for medical records) of the PHR, which is to be the core of the system, has yet to be popularized, and there is a pressing need to give up on high-cost/low-advantage aspects, and to move on to creating a new earnings structure.

 2. Our Plan

  • Although it remains difficult to ensure earnings through preventive care under the current Japanese medical insurance system, we plan to establish a system of token payment in collaboration with Health Insurance Associations, pharmacies and point programs. We will reestablish the earnings model of the whole health care field, solving the problems concerning EHR, and returning profit by supporting the development of new drugs, medical equipment and analysis services.


Principles of PHR from a Viewpoint of Privacy Protection

- Effective, but not well referred guidelines have already been set in Japan, based on past considerations as below;

  1. Ensure that individuals can collect, store and utilize information concerning their own health with the aim of maintaining and improving QOL (Quality of Life).
  2. Information shall be owned by individuals, to be collected, stored, referred to and disclosed on an individual base, and controlled by themselves.
  3. The target health information covers a wide range including prevention, medical treatment and nursing care.
  4. (For GDPR Requirement)
    Personal data should be trackable and removable  through blockchain technology and meet “Right to be forgotten” policy

- As we strongly support and comply to these guidelines, adding economical policies below;

  • To make individuals effectively controllable their records, enough information should be given as;
  1. Leakage risks should be visualized even the information is anonymized
  2. The anonymization process should be done multidirectionally, with multi-evaluators (Multi-Privacy-Notions) as follows;

    k-anonymity, ℓ-diversity, t-Closeness, δ-Disclosure, ε-differential, δ-Presence, etc.

  3. Value of the information should be presented concurrently according to the anonymization level
  • To promote secondary, meaningful use of the information, PHR should take initiatives to include EHR systems with keeping individuals’ ownership
  • Collected information should be integrated and referred under individuals’ approval

Overview of PHR Cloud with Wearable Devices

  • Here is a sample of PHR design combing wearable devices and internal/external healthcare facilities information systems. In addition to normal PHR data storing and searching, we have specific data evaluation/visualization engine shown in violet polygon in the chart, being developed through the corporation with the companies well-practiced in strict privacy protection regulations in the European Unions.
