Unsecured Documents
Protocol and image files created in standard mode or created with previous versions
of Image Lab are unsigned, unsecure documents. Unsecure documents remain
unsecure. When you open these files in secure mode, you can make changes to
these files and save them without restrictions. A document log is generated for
changes to these files, but the log is not viewable in standard mode. You must log in
to secure mode to see the log.
You can also open unsecure documents in secure mode and sign them. You can
make changes to these files and save them as secure documents. The original
unsecure document remains unsigned and unsecure. The new document is saved
as read-only with an incremental revision number and Image Lab generates an audit
log. Image Lab will not be able to overwrite the secure file, but it can overwrite the
original unsecure file.
Secure Documents
Protocol and image files created in secure mode are known as secure documents
and generate a log. However, until they are signed, such documents save as
standard files. Only after they are signed are they saved with the secure
extension(.sptl or .sscn). Image files generated from signed protocols automatically
open the signing dialog box when the scan completes.
If you create a default protocol based on an existing signed protocol, the resulting
new default protocol cannot be edited.
Note: A secure document can be saved unsigned. Likewise, a signed
document can be saved as a new, unsigned file. In this case, the saved file is
still a secure document. All changes to the document are captured in the
document log.
