previous versions of Acrobat contained a
capability called
examined document inaccurate and this
has been renamed
to remove hidden information to more
accurately describe what it does
some other types of information that can
be hidden
and removed with the remove hidden
information tool
are meta-data attachments comments form
field additional signatures
deleted or crop content overlapping
objects
and now an acrobat 10 also JavaScript
links
and actions there are many reasons why
you might want to remove hidden
information from Acadia
for example if you need to comply with
regulations like the Health Insurance
Portability and Accountability Act
the US Privacy Act or for court filings
if you're about the publisher PDF online
you probably want to remove any personal
information like
who created the document or when it was
created and if you've been inserting
snarky comments on a PDF
you'll definitely want to remove those
before the PDF goes up for wider
distribution
now let's take a look at how to remove
hidden information from the PDF first
you select Tools and then you select
protection move down near the bottom of
the protection panel where it says
hidden information
and select removed hidden information
remove hidden information panel opens on
the left and shows you the results
if you to roll down any of their oath
you can see
all the different items that are going
to be removed
the hidden information that Acrobat
found in this PDF is
a lot of meta-data and then two items
have deleted
or cropped content if you want to get a
closer look
at exactly what within the meta-data
that's going to be removed
you can just select show preview and it
will show you
so in this case I can see that have the
author name
the title and they may or may not want
to have that included in this PDF
I'm going to cancel love this now
and go back over to the remove hidden
information panel
if I decide that it's okay to leave the
letter dated and eye candy so like this
and then it will not remove that
information but for right now
look selected and I'll hit removal
Acrobat then tells me what else is going
to remove
from this document and I select okay
noticed that even though Acrobat tell
it is done removing the selected items
that the changes are not apply it and
tell you save the document
but don't worry if you try to close this
PDF right now without saving
after that will prompt you to save it
first to remove hidden information tool
is efficient and it lets you see exactly
what you're going to remove
but if you know that you always want to
remove hidden information
you can go to your preferences select
documents and
down here words is hidden information
you can select to remove hidden
information one closing document
or remove hidden information when
sending document by email
and that way it automatically happens
you don't even have to use the tool
within Acrobat another way to automate
the removal love hidden information
in Acrobat is to use the action was
erred you can create your own action or
you can use an action that comes with
back about 10
publish sensitive documents this action
allows it to mark for redaction
then remove hidden information and then
reduce file size
so it's a quick way to get through
multiple processes
for ultimate efficiency in removing
hidden information from a PDF
you want to use the bar of soap tool
which is known formally as
be sanitized document tool when I select
sanitize document
Acrobat displays a list that shows me
everything that is going to be removed
once they save the document so when i
press OK
it props pay for a place to save it it
will give it a
sanitary prefix

sanitized file
