Communication verification system

摘要

A communication system verifying the source of a file. The system uses a first link between a sending computer and an authorizing computer which contains a request for a PIN associated with the intended receiving computer. This PIN is returned to the first computer via a second link which permits the sending computer to properly communicate in an encrypted manner with the receiving computer. An alert or notice is sent to the receiving computer by the authorizing computer to further verify the authenticity of the file being sent to the receiving computer from the sending computer.
