Internet, intranet and other network communication security systems utilizing entrance and exit keys

摘要

A security system emphasizing ultra-long keys for restricting access to a host computer or server, through a network such as the internet or an intranet, from a remote computer by the usage of an electronic "double-sided pass key" established on a portable memory medium such as a CD-ROM. The key has ultra-long, constantly revised entrance codes to permit access to the server and ultra-long, constantly revised exit codes to authenticate or to validate the transactions conducted during authorized access and before termination of the authorized connection. If the proper exit code is not received the transactions of the connection are erased, thus aborting a hijacked connection. In addition, the portable memory medium includes defensive tools to thwart trespassing attacks on the security system including electronic dye markers and electronic homing beacons which serve to identify and to locate trespassers.
