point of origin of the message, where this creation step further
comprises the inclusion of a self-removing code in the message.
Although we recognize that Hansen teaches the ability
of a message originator to include codes within a message which
may result in the removal of the message, the teachings in this
reference indicate that it is not self-removing. Under the topic
“4. Security” at the second column of page 28 of Hansen’s
article, the article initially indicates that the Ness script is
a program and then teaches the following (bottom of column 2):
The Ness implementation has features that
make it more difficult--though by no means
impossible--for a villain to damage an unwary
user. In particular, no script is ever
executed--or even compiled--without
permission from the reader. Users may
choose among two options for this protection.
This same teaching is conveyed to the reader at the top of the
second column at page 29:
Finally, the design must provide some control
so nefarious authors are not as free to
produce programs which can damage readers’
files. With Ness, the reader has the option
to empower a script or not and also the Scan
mode which aids in reviewing the script for
potentially dangerous statements.
