<p>An apparatus and method creates a secure document with installed software at a sending location. The secure document includes an executable program which, when received and opened, runs a program that can decrypt the secure document. A pass word or phrase may be included to prevent unauthorized access to the secure document. A secure reply option may be provided which, if selected, permits the received program to encrypt a reply and to transmit the encrypted reply to the sending location. The installed software can then open the reply. In alternative embodiments, the executable program contacts a predetermined global computer network site which provides a program to decrypt the secure message. Further, the executable program and/or the program downloaded from the site enables communication with a second global computer network site which can be instructed to take a particular selected action. A confirmation can be returned to the sending location, either from the receiving location or from the second global computer network site.</p> |
