  • Patent number: 4114139
    Abstract: A security controlled information exchange system for controlling the orderly exchange of information between two or more users under primary control of security identifiers. Each user is set up with a local user indentifier (LUID) and a number of remote user identifiers (RUID). Also, associated with selected ones of the RUIDs, are jobs which are to be communicated. A user initiates communication transfer by forwarding to another terminal its LUID and the receiving user compares the received LUID with its list of RUIDs and if a compare is made, the receiver forwards its own LUID to the initiating party. If a compare is is not made, it disconnects. The initiating party then compares the LUID which has been forwarded to it with its list of RUIDs and if no compare is made, it disconnects. If a compare is made, however, it holds onto the line and the called party then sends the jobs which are associated with the RUID which corresponds to the LUID which it received.
