Fujitsu and the Keio Research Institute at SFC today published a white paper on the concept of a Trusted Internet, which enables general-purpose verification of the authenticity of data on the Internet by adding a new layer called “Authentication.” “Layer” between the existing Internet layer and the application/web layer. The white paper contains the results of research conducted in the “Trusted Internet Architecture Laboratory”. (1).

Trusted Internet will allow users to confirm the validity of various previously difficult-to-verify data on the Internet based on additional information about data creation and processing, validation and evaluation data by third parties who have viewed the data, and information about the physical location associated with the data (sensor data, etc.). This allows users to judge the reliability of information from different perspectives, thereby preventing the use of unverified information and the dissemination of false and unverified information (“fake news”), whether intentional or otherwise.

Moving forward, Fujitsu and the Keio Research Institute at SFC will promote the development of new technologies in the Trusted Internet Architecture Lab with the goal of contributing to the realization of the Trusted Internet by FY 2028 by implementing an “Authentication Layer.” and browser functions to verify the authenticity of data from users’ devices.

Fujitsu and Keio Research Institute at SFC first presented the concept of “Trusted Internet” at the W3C (World Wide Web Consortium) annual meeting and W3C TPAC 2022 meeting (September 12-16, 2022) and defined the concept based on feedback. various experts.


The deliberate dissemination of false or unverified information and data online is a growing threat to society, and according to some estimates, “fake news” costs the global economy at least $78 billion a year. (2).

Traditional methods of ensuring data authenticity include document approval management systems and data tracking systems such as baggage delivery tracking systems that use custom methods to record data traces.

However, verifying large volumes of data on the Internet remains a challenge, highlighting the need for a general-purpose method to prove data authenticity.

To address these issues, Fujitsu and the Keio Research Institute at SFC published a white paper outlining the concept of the “Trusted Internet” as a result of their research in the joint research base of the Trusted Internet Architecture Laboratory, which was established in April 2022. Through their joint research, the two parties aim to promote Research and Development of technologies that enable reliable data exchange on the Internet by pooling their knowledge and know-how to solve data authenticity issues.

The Keio Research Institute at SFC, the Japanese base of the W3C, has been promoting the standardization of web technologies since the 1990s and has been at the forefront of the global standardization of the Internet through various activities. Fujitsu has been an active player in the IT field since the early stages of the Internet and has a variety of technologies and expertise, including well-established security-related technologies, as well as newly developed cutting-edge technologies, including unique identity technology to connect different companies. identity infrastructures.


The Trusted Internet concept provides a new approach to simplify the verification of the authenticity of information on the Internet. In this approach, the creator or a third party can add background information as proof of the authenticity of the original information and verify the information by adding a “Verification Layer” to the Internet layers shared with users.

This configuration can be implemented without affecting the existing Internet and allows Internet users to use the Internet and applications as usual and obtain the necessary information to verify the authenticity of data and information when necessary.

Additional information that can be used to verify the authenticity of the data may be provided by people and devices during the creation of the data (name, affiliation and qualifications of the creator of the data). [person or corporation] or device used, location and date and time). In addition, additional information may be added after the data is created, including inspections and evaluations by third parties such as independent experts and data obtained from physical locations, including sensor measurements. Users can search and verify additional information needed to verify the authenticity of the data on the Internet at the Verification Layer, where the data will be stored as graphical data.

In this way, users can assess the authenticity of data from a multifaceted perspective, which makes data-driven decisions more accurate and helps prevent the spread of unverified information.
