Thank you very much for your purchase of Ryoden products and services. My name is Ryuji Takeuchi and I am an engineer with Ryoden Corporation’s New Business Promotion Department.
As an introduction to security technology, I would like to explain to you how personal data is utilized. I will divide my discussion into three parts.
At Global ICT Summit 2014, Martin Jetter, CEO of IBM Japan, Ltd., offered the following remarks:
IBM thinks of data as a new natural resource. It’s a resource that will bring economic growth and enormous change to society. Every century has its once-in-a-century discovery. If the 18th-century discovery was steam power, the 19th-century breakthrough was electricity and in the 20th century it was hydrocarbons, the once-in-a-century discovery of the 21st century is centrally collected data.
This declaration that “data is the oil of the 21st century” is often quoted in a wide range of literature and public addresses.
In its 2018 telecommunications white paper, MIAC noted that, while the value of Big Data has swelled amid the advance of ICT, the data worth collecting and storing should be collected and stored.
As a result of his research as an AI specialist into the value of data, Professor Hashida of the University of Tokyo has proposed and developed the Personal Life Repository (PLR), a tool to realize in concrete form the MyData principle, that the person to whom the information pertains guides how that information is used. PLR is a distributed personal data store (PDS) that satisfies the three requirements of low price, safety and versatility.
1. Low Price
Unlike general applications, PLR does not require dedicated servers. PLR is used on the PLR cloud, a cloud service domain where individuals can register and open accounts, basically for free. Currently PLR uses Google Drive, but plans call for support of other services as well, such as OneDrive, DropBox and iCloud.
2. Safety
In addition to end-to-end encryption, PLR features digital rights management (DRM), which enables the user to limit how the data is used. This feature distinguishes PLR from most information systems, which vest a central administrator with authority to access all manner of data on the system, leaving them vulnerable to misuse that can lead to massive data breaches. With PLR, data management is distributed to individual users and data is encrypted, so large-scale data leaks do not occur.
3. Versatility
Professor Hashida, the progenitor of PLR, incorporates data normalization into PLR as a basic specification, bearing in mind the expected use of the data by AI. This normalization enables many varieties of personal data to be shared by PLR.
PLR, which enables autonomous management and independent use of one’s own personal data, can be used with a wide range of services that handle personal data.
Ryoden is continuing discussions with customers on the themes of mobility, healthcare and smart cities. In connection with those discussions, we are providing an introduction to applications slated for release in FY 2020. If you’re interested, please don’t hesitate to contact us.
