Proposed On-site Document Sharing System using FIDO

With the advancement of information and communication technology, online file exchange such as document delivery, business reporting, and submission of reports within or between companies has been widely used. With the increase in convenience, however, security threats have also increased due to the high risk of external leak of files exchanged online. Although companies employ network separation by building an internal corporate network, this has a drawback, i.e., files cannot be used outside such as a work-from-home environment. To solve this problem, this paper proposes a secure file sharing system using the Fast IDentify Online (FIDO) technique. This service is expected to contribute to the improvement of file sharing security because it can encrypt and decrypt files through FIDO authentication when viewing internal files from outside.
