  • The Internet was designed for machines, not humans, and hence, nobody owns a digital identity. Instead, a digital identity is rented from a website and an application. This lack of unique and secure digital identities has resulted in confusion in the online/cyber world. Digital identities pose one of the oldest and most difficult problems with regard to the Internet. There is still no way to use digital credentials to prove, own, and control an online identity, namely a self-sovereign identity, in the same manner we do in the offline world, particularly without a trusted third party. This article discusses the current open standards for digital identities, proposes solutions pertaining to digital identities in the future, and introduces the concept of a blockchain-based self-sovereign digital identity without the need of trusted third parties.

  • Digital twins are digital replicas of objects and systems in the real world. These digital replicas in a virtual environment can be connected with smart sensors and a variety of analyses, and simulations of real-time data from these sensors enable effective the operation, rapid feedback, and future predictions of real world phenomena. Until now, digital twins have been adopted and used mainly in the field of manufacturing, especially for smart factories. As digital twins are expected to be useful not only for productivity improvement but also for social problem solving, it is predicted that they will be extended to other fields such as those of transportation and cities. Digital twins will especially help realize smart cities through real-time monitoring, operation, and predictions using virtual digital twin cities. This paper summarizes the trends in digital twins for smart cities, the concept of digital twins, their application to smart cities, the strategies of various countries, and the development status of companies.

  • 인터넷의 확산과 유비쿼터스 환경이 도래함에 따라, 사용자가 관리해야 하는 digital 형태의 identity 정보가 기하 급수적으로 증가하고 있다. 또한 이러한 identity 정보는 서비스 제공자에 의한 오남용이나 외부의 해킹 위협에 직면하고 있으며, 이는 사용자의프라이버시를 침해하는 결과를 가져온다. 이에 따라, 사용자의 digital identity 정보를 관리하는 identity 관리 기술은 최근 그 중요성이 매우 높아지면서 국내외에서 많은 연구가 진행되고 있다. 본 고에서는 digital identity 관리 시스템에 대한 개요와 identity관리 기술에 대한 연구 및 시장 동향, 표준화 동향 및 관련된 연구 프로젝트에 대하여 살펴본다.
