Data e-TRUST

Realizing the safe, secure, and free exchange of data

Accelarating safe and secure data exchange by granting trust to data

The realization of a connected digital world that transcends individuals, companies, and industries such as global supply chain, super cities, healthcare and environmental protection represents a major issue in today’s digital society. To this end, the realization of digital trust for the reliable connection and safe and secure exchange and utilization of data has been gaining increasing importance.

Data e-TRUST offers customers a set of APIs that enable secure and reliable data exchange and utilization between different services and between individual users and businesses.
Leveraging Fujitsu’s proprietary IDYX and CDL technologies, this service enables tamper-proof management of data trails including the proof of origin, ownership, and authenticity of data. By granting trust to all online transactions involving data such as electronic documents and digital content,
Fujitsu’s Data e-TRUST supports customers in solving business and societal issues and ultimately contributes to the realization of a sustainable society.

Features of Data e-TRUST

Data e-TRUST provides customers with a secure, on-demand and distributed data exchange mechanism, electronic credentials, and a flexible ledger that extends the blockchain to ensure the authenticity and security of data exchange between different systems and services. In this way, Data e-TRUST supports both the authentication of all information related to individuals and corporations in digital transactions and the safe, secure, and free exchange of data, strongly promoting digital transformation and solutions to various issues in financial, manufacturing, retail, distribution, and medical sectors.

Secure linkage of distributed data

Data e-TRUST enables data linkage across individual users, organizations, and companies, allowing it to provide governance in data ownership and disclosure, including consent of individual users/organizations, as well as finely controlled access.

Ensured data authenticity

Data e-TRUST offers a wide variety of digital credentials that can prove the identities of individual users, organizations, and companies which can be used for authentication  scenarios for various services.

Tamper-free evidence management

Data e-TRUST can provide accurate visibility of value chain and customer journey by interconnecting transaction histories and evidence of activities among individual users, organizations, and companies.

Functions provided by Data e-TRUST

Three core functions enabling the creation of ecosystems, business process reforms, and new businesses

Enables confidential management of each companies' data to control data linkage across companies

Data e-TRUST finely controls data items to be linked between confidential individual users and companies' distributed database, allowing exchanges of personal information only after obtaining the user's consent, making it possible to achieve secure and on-demand distributed data linkage across individual users and companies. Moreover, individual users and companies can manage their own diverse data and pass it on to multiple companies and services, enabling them to exercise detailed control over distribution location and privacy, thereby enhancing data ownership and governance for information disclosure.

Enables exchange and utilization of various kinds of information by adding digital credentials

Fujitsu’s IDYX technology, a solution designed to guarantee that data to be used is accurate and not falsified, enables the issuance and use of various electronic credentials for digital information and ensures the authenticity of information exchanged in digital transactions. In this way, it supports a variety of authentication scenarios that require verification of digital information (i.e. enhancement of authentication processes by checking an individual's identity and personal credentials, information concerning corporate performance, provision of one-stop services such as contract procedures through interconnected customer information, management of copyrights and ownership of electronic documents and digital content, etc. ).

Manages transaction histories and evidence of activities in a tamper-proof way

Fujitsu’s CDL technology enables individual users and organizations to manage transactions and evidence of activities in a tamper-proof manner by extending the blockchain and enabling flexible, scalable, and centralized management of transaction histories across individual users and companies. This will enable the use of various kinds of digital transaction histories to prove the integrity of different business activities and social contributions. For example, supply and value chains can be more highly visualized and controlled by interconnecting data on carbon footprint and consumer behavior with data on CO2 emissions.

PoVTEIKOKU DATABANK, LTD.Joint trial aiming at social implementation of "Japanese electric seal"

Challenge

Proving the authenticity of digital documents and whether they are issued by companies or organizations which actually exists

Solution

To implement a trusted exchange of digital documents between companies using e-seals based on corporate certification

Fujitsu and Teikoku Databank, Ltd. conducted a joint trial aimed at the social implementation of a Japanese version of an electronic seal (hereinafter 'e-seal').
In this jointly-managed trial, a service model (prototype) for utilizing e-seals was developed by linking Fujitsu's Data e-TRUST, Teikoku Databank's knowledge of corporate identity verification, and the "Box" content cloud offered by BOX Japan. By using this prototype system, digital viability was confirmed through adding and verifying e-seals in the exchange of documents between corporate organizations expected in actual businesses.

Going forward, Fujitsu will continue to promote the use of e-seals to drive corporate digital transformation, and realize a society in which transactions involving all types of digital documents can be conducted smoothly and appropriately.
