| 摘要 |
A method or apparatus for a computer or microchip with one or more inner hardware-based access barriers or firewalls that establish one or more private units disconnected from a public unit having connection to the Internet, and one or more of the private units have a connection to one or more secure non-Internet-connected private networks for personal and/or local administration. The hardware-based access barriers include a single out-only bus and/or another in-only bus with a single on/off switch and/or both buses, each with a single on/off switch. The hardware-based access barriers can be positioned successively between an outer private unit, an intermediate more private unit, an inner most private unit, and the public unit, and each private unit can be configured for a separate connection to a separate network of computers that excludes the Internet.
