Internet connection management system for information communication device, method therefor, and internet connection management program installed in information communication device

Abstract

A connection management system is a system for managing the connection of a smartphone (1) for a child to a specific connection target via the internet, the system characterized by having: a filter program server (9) for restricting the passage of a data packet to the internet, on the basis of the destination address of the passed data packet and a source IP of the smartphone (1); a VPN server (6) for establishing between the VPN server and the smartphone (1) a tunnel connection (27) for passing all communication traffic from the smartphone (1), and forwarding to the filter program serve (9) the data packets passing through the tunnel connection (27); and an API server (8) that is connected to the VPN server (6), confirms the existence of the tunnel connection (27) at a prescribed timing, and cuts off the internet connection of the information communication device when it is determined that the tunnel connection does not exist.

Description

technical field [0001] The present invention relates to a system, method, and Internet connection management program for managing the connectivity of applications connected to the Internet in mobile information communication devices such as smartphones. Background technique [0002] In recent years, victims of Internet crimes targeting minors have increased dramatically. Consequently, many parents wish to limit their children's connections to harmful Internet sites. [0003] Here, when the Internet connection device used by the child is only a personal computer or the like that is permanently connected to the home local network, it is relatively easy to restrict connectivity to the Internet. That is, in this case, by installing a function called parental control on a router or the like that controls network traffic, it is possible to finely limit connection destinations and use time. [0004] However, when the Internet-connected device used by the child is a smartphone, it...

However, according to this method, it is impossible to prevent the devious behavior of using other applications other than the restricted application in order to browse the animation content.

For example, even if the start-up of an application dedicated to video viewing is restricted, it may not be possible to restrict video viewing through a browser.

[0006] In addition, the connection destinations that can be realized at the terminal level are limited only when the URL contains a predetermined character string or a specific IP address, so it cannot effectively deal with harmful content that frequently changes the connection destination IP address. make connection limit
