            Bug ID: 109199
           Summary: [Feature Request] (or extension): remove/block
                    sensitive content
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: eduardo at openxarxes.com

Could be something as described in:
https://helpx.adobe.com/es/acrobat/using/removing-sensitive-content-pdfs.html

Or even better, the issue is, while writing a report for internal (within the
organisation) use, at some point there could be a need to make it available to
public or third party, though with some sensitive information removed (or
blocked).

For some documents already exported to pdf (and signed) I have recomended a
solution mentioned in the link above, but for the new documents that are being
made we have given instructions to users in order to use a combination of these
techniques:

1.- Use conditional text, so there will be a variable with values 1 or 0, if it
is 1 text will show, if it is 0 alternative text will show (for example "*****"
instead of "hello"). Advantage: you can use more than one variable to control
which text is displayed and which alternative text is, a lot of control.
Disadvantage: time consuming, have to set it up for every text, and not very
"user friendly". Have to use hidden text for the variable, not straight
forward.

2.- Mark sensitive words you want to censor with an alternate style (for
example a cloned style of the parent style) then when exporting to pdf, change
the format of the style to something meaningful and make use of advanced search
techniques and regular expressions so the specifically formatted text gets
substituted by same amount of "*". Advantage: it works. Disadvantage: you need
to remember to mark with the style and then change it, eventually there is a
need to duplicate as many styles as needed if the words you want to censor are
written in different areas (so parent styles) within the document. Also the
user must learn regular expressions patterns, and advanced search and replace
techniques, this is good but no so user friendly and straight forward.

3.- Plain and simple search and replace, so for instance, a passport number or
a Name, Surname, Address... etc... any word you want to censor, could be easily
be searched and replaced for any string that hides it "* * * * * *" or else. ->
Adv: easy -> Disadv: in large documents with many different words it is kind of
"manually" feeling and can lead to mistakes.

4.- Also we have instructed users to combine the above practices with the use
of "versioning control" so they can get the uncensored document back or use the
censored one, instead of saving to versions of the same document with different
names (this may be good at the very end, when document is approved by
management, original exported to pdf and signed). And to use "control of
changes", notes and other techniques to get track of the censored or removed
text.

So, I think I have expressed my feature request (or extension) kind of clear,
in any case, I can make an effort to explain it clearer.

I was thinking of a feature (extension) so while writing the document, words or
string of text could be easily marked (right click button and option or keyword
combination) to be censored later, also let which kind of censor to apply
(replace characters with specific symbol ex: "*", or gray out, black out,
etc...), keep track of censored text, search in the document for similar text
that have been unmarked, it might have been unseen or just plain forgotten, for
instance, if I have marked 123456 (passport number) as sensible text to be
censored, it will be nice to check if that pattern is in some other part of the
document and unmarked, so it checks and tries to alert to possible mistakes
(forgot to mark).

Also, the censured report could/should have an option to add a watermark to
every page, so it is noticed that it is a censored document version from a full
document with all the info in it.

That's about it, I know I should maybe try to start an extension about this...
probably, but I need to get the programming/extension skills to do so and also
first thing first, make it public so if anything is out there similar to this,
maybe you can point me on the right direction.

Thanks!
