Abstract
In order to prevent illegal data tampering or leakage of information caused by devices connected to a system such as a conference system and save time and trouble in setting functional restrictions separately from an application, an access point uses authentication information for authenticating electronic devices operated by participants who participate in a conference also as the information to decide functional restrictions on the electronic devices during the conference.
