Digital transformation has caused continuous changes to the world at an unprecedented speed, leading to a new paradigm separate from the past. Companies, individuals, businesses, and systems are intricately connected together, which necessitates the handling of rapidly increasing data. With this, the verification of quality, authenticity, and eligibility of all factors has grown difficult. In order to resolve this issue, it is important to have ICT simplify the mechanism for achieving trust in the digital era, which is distributed and correlated in a complicated manner. This paper presents Fujitsu Laboratories' approach for how to use advanced technology in the realization and social implementation of trust in the digital era, which has taken on more significance than ever before in our increasingly complex world. © 2020 Fujitsu Ltd.
