Message from Faculty
Focusing on trust and security architecture for the digital age and its deployment strategy, we aim to address social issues from the users' perspective, based on internet, mobile, and device technologies, so that people can live safely in an increasingly unstable society. "Digital identity" plays a significant role in this. We will face head-on the difficult task of simultaneously satisfying different, often conflicting requirements. Continuing to change and respecting diversity will enrich our imaginations in fun ways. We will solve the challenges we face together and create and protect the digital society of the future.
