A new white paper defines a new concept for simplified data validation on the Internet

TOKYO, Oct 13, 2022 – (JCN Newswire) – Fujitsu and the Keio Research Institute at SFC today published a white paper on the concept of a trusted Internet, which enables data validation on the Internet in a general-purpose manner by adding a new layer, called the “Authentication Layer” , between the current Internet layer and the application/web layer. The white paper contains the results of research conducted in the Trusted Internet Engineering Lab (1).

A trusted Internet will enable users to confirm the reliability of various data on the Internet that were previously difficult to verify based on additional information related to data generation and processing, information on confirmation and evaluation by third parties that reviewed the data, and information about the physical space related to the data (sensor data). , etc.). This allows users to judge the reliability of data from a variety of viewpoints to prevent the use of unverified data and the dissemination of false and unverified information (“fake news”), inadvertently or otherwise.

From now on, Fujitsu and the Keio Research Institute at SFC will promote the development of new technologies in the Trusted Internet Engineering Laboratory with the aim of contributing to a “trusted Internet” by fiscal year 2028 by implementing “authentication layer” applications and browser functions to validate Data from users’ devices.

Fujitsu and the SFC’s Keio Research Institute initially presented the concept of a “trusted Internet” at the annual W3C (World Wide Web Consortium) and W3C TPAC 2022 Meeting (12-16 September 2022) and defined the concept based on the opinions of various experts.


The deliberate spread of false or unverifiable information and data on the Internet is a growing threat to society, and according to some estimates, so-called “fake news” costs the global economy at least $78 billion annually (2).

Traditional methods of ensuring data validity include data tracking systems such as document approval management systems and baggage delivery tracking systems that use individual methods to record data paths.

However, validating large amounts of information on the Internet remains a challenging task, highlighting the need for a general-purpose method to validate data.

To address these issues, Fujitsu and the Keio Research Institute at SFC have published their white paper outlining the concept of a “trusted Internet” as a result of research in their joint research base, the Trusted Internet Engineering Laboratory, established in April 2022. joint, to promote research and development of technologies that enable reliable data exchange on the Internet by combining their knowledge and knowledge to solve problems related to data validity.

The Keio Research Institute at SFC, the Japanese base of the W3C, has been promoting the standardization of web technologies since the 1990s and is 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, possessing diverse technologies and knowledge, including well-established technologies related to security as well as recently developed cutting-edge technologies including Sovereign Identity Technology to interconnect various identity infrastructures.


The concept of a trusted Internet represents a new approach to simplifying data validation on the Internet. Under this approach, the originator or a third party can add background information as proof of the authenticity of the original data and verify the data by adding an “authentication layer” to the Internet layers that are 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, if necessary, to obtain the information necessary to verify the correctness of data and information.

Additional information that can be used for data validation by people and devices can be provided at the time the data is generated (information about name, affiliation, and qualifications of the data creator). [person or corporation] or device used, location, date and time). Furthermore, additional information including verifications and evaluations from third parties such as independent experts and information obtained from physical spaces including sensor measurements can be added after the data has been generated. Users can search and verify additional information needed to validate data on the Internet in the authentication layer, where the information will be stored as graph data.

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