Patent ID: RE42212

Claim:
An anti-virus A protection method for use within a data transmission network to protect against the transmission of unwanted data from a transmission originator having a plurality of assigned security codes corresponding to a plurality of data security levels to a subscriber/recipient having a plurality of assigned discrete subscriber/recipient IP address codes over the data transmission network including a data transfer control means and a plurality of data transmission ports corresponding to the plurality of security levels, wherein said plurality of assigned security codes includes a first data security level code element and a second data security level code element and said plurality of data transmission ports include a first data transmission port and a second data transmission port such that data are transmitted through the first data transmission port to the subscriber/recipient when said discrete security code element is authenticated as a first data security code level element and data are transmitted through the second data transmission port to the subscriber/recipient when said discrete security code element is authenticated as a second data security level code element, whereas the anti-virus protection method comprising the steps of: generating a transmission pack including a discrete security code element corresponding to the data security level selected by the transmission originator of the data to be transmitted and a discrete subscriber/recipient IP address code element corresponding to the discrete subscriber/recipient IP address code of the subscriber/recipient, subscriber/recipient; transmitting data and said transmission pack to the data transfer control means that includes circuitry and logic to scan said transmission packets from the transmission originator for discrete security code elements and discrete subscriber/recipient IP address code elements to control the transfer of data from transmission originators to subscriber/recipients through said data transfer control means; scanning said transmission pack to authenticate discrete subscriber/recipient IP address code elements and discrete security code elements; and transferring data in authenticated transmission packs to the subscriber/recipient through the data transmission port corresponding to the data security level.
