17-3 A Study on a Database Management Method for Protecting against Leakage of User Information

Abstract

Secure interactive transmission of user information makes it feasible to provide services that reflect viewer information on communications networks. For viewers to feel confident providing information, broadcasters that receive information must inspect and manage it in a secure manner. In this paper, we investigated a database management method for protecting against leakage of user information. In this method, even if the information in the database is leaked, users cannot be specified by the data in the database. We also investigated a database inspection method in which it is possible for items that can be inspected to be limited dynamically at each terminal by the database administrator.
