  • Patent number: 10637830
    Abstract: To provide a VPN access control system, an operating method thereof, a non-transitory computer-readable recording medium having a program recorded thereon, a VPN router, and a server capable of reducing the effort of work of an administrator and quickly permitting remote access. A VPN access control system includes a VPN router and an image server. The VPN router executes a router authentication process based on router authentication information, and the image server executes a server authentication process based on server authentication information. The image server receives an access right granting request from a portable terminal of a registered user to which the access right has been granted and executes a first user registration process. The VPN router executes a second user registration process based on a command from the image server, and transmits an authentication information notification to a user who is an access right granting target.
