Abstract
With The Internet VPN system of IPsec, construction sites can be connected with broadband network. But overseas sites, small-scale construction sites and loaned employees still connect with narrowband network. Because of the security system (i. e. Firewall, NAT), IPsec-VPN cannot use for the above network. And when the ID and password are stolen, it is easy to access to the company network from the world in secret. So we developed the new system that connects SSL-VPN and biometrics system simply. By using this system with a fingerprint, we can connect them safely. And we can cut cost to 35%.
