Design and evaluation of a dedicated information environment with both portability and confidentiality

COVID-19 has led to a rapid increase in the use of video conferencing and video calls over the Internet. In this paper, we propose a low-cost, portable, and highly confidential occupied information environment. The authors developed a secure input/output device in the NICT's “SecHack365” program for fostering young security innovators. By improving the device and integrating it with traditional Japanese culture, we quanti-tatively evaluated that the device can achieve sufficient up-time, lightweight that does not burden the body, and has a price that does not strict on the wallet.
