Removing Sensitive Information

Hi,
I used the Text Touchup tool in Adobe Acrobat Pro 6 to delete some sensitive information from a .pdf file. After deleting the info, I saved the .pdf file with a different name.
Is there any way someone could recover the deleted information if they got a hold of the document?
Thanks,
Bill

An example of this is a scanned document on which OCR was done. In this case you often have the scanned image of the page and an invisible layer of text which is used for searching. In such a case, deleting the letters from the image would still leave the hidden letters. That isn't the case you describe, but I don't know if there may be other such cases.

How to disable 'Remove Hidden Information' popup when closing PDF in Acrobat X on Mac?

How do I disable the function that causes the 'Remove Hidden Information' popup when closing PDFs in Acrobat X? I'm using OS X 10.9.4 on a Mac?
I've searched online and was directed to Preferences>>Security (enhanced) to uncheck 'Unable Enhanced Security', but it wasn't checked.
This box (see screen shot) opens each time I close a PDF. I'm forced to select an option before closing.
Please help.
Thanks.

Go to the menu Acrobat>Preferences
In the Preferences window's "Categories" pane, select "Document"
In the "Hidden Information" section deselect both check boxes
Click the OK button
You should be good now.

Remove Hidden Information tool

Hi,
I would have a question regarding Acrobat's 'Remove Hidden Information' tool. Under Tools, Protection there is the 'Remove Hidden Information' tool. When I click it the results can be seen on the left side. Under 'Comments and markups' the sum of objects can be seen. I figured out that it detects bookmarks, links (internal, external) and objects described here: http://help.adobe.com/en_US/acrobat/X/pro/using/WS58a04a822e3e50102bd615109794195ff-7e7f.w .html.
But it also detects some other objects as well which I am not aware of (based on the number of objects detected). I also know that it counts 2 objects when using 'Replace text' from the link above.
Does anybody happen to know what additional types of objects does this tool detects and how to search for them in the document?
Thanks for your help,
Csanad
I use Acrobat version 10.1.5

The hidden text is the collection of glyphs on the PDF page that use text rendering mode 3 (no stroke, no fill).
Any links placed in association with such hidden text are not "hidden" (that is not how it works with PDF Link annotations - see ISO 32000-1:2008).
Any Link annotation placed in a PDF are the same as any other Link annotation (with the exception, of course, of whatever the link's Action happens to be).
So, no special sauce for links that were placed in association with now removed "hidden text".
In context of what you've written it may be that you will have to select - Ctrl+click the Link annotations of interest then tap the Delete key.
Be well...

Protecting text files with sensitive information

I have an app where users log in and upload files with very
sensitive information (pdf's or word doc's). Depending on the
permissions an user can open and view or save specific files. I'm
saving files out of the web server folder and using middle cfm
page(docs.cfm) as a wrapper:
Link to the docs.cfm:
<a href="##"
onClick="MM_openBrWindow('docs.cfm?name=#docFile#','fileDoc','scrollbars=yes,resizable=ye s,width=750,height=550')">#docName#</a>
and here is docs.cfm code:
<cfheader name="Content-Disposition" value="attachment;
filename=#URL.name#">
<cfcontent type="application/unknown"
file="#Application.docsPath##URL.name#" reset="yes">
Application.docsPath variable points to D:\myFiles\ folder
(not in the web server directory).
It is sill possible to open file if you guess the file name.
Is it any way to protect files from unauthorized users and to
block them if they try to guess and open a file?
Thanks,
b.

I think the best way to protect them would be to store them
in a database and
restrict access to the database. The database should also be
outside the DMZ.
SQL 2005 has some field level encryption if you want to get
supper protective,
but that has some limits of data length that you'll need to
work around. We
encrypyt user passwords with SQL 2005 and it works great.
More info here:
http://blogs.msdn.com/yukondoit/archive/2005/11/24/496521.aspx
The other possible solution is to place all a user's files
into 1 zip file and
encrypt and password protect it, not as secure, but would
work. You could use
their userid and email or something for unique username's and
passwords per
file. Each user would have their own zip that you unzippped
to give them access
to what was inside. When they uploaded the file, you just add
it to the zip.
This way you could allow them to upload differant types of
files and handle
them all the same way.

Hiding sensitive information like SSN from being displayed as text

I want to hide sensitive information like SSN being shown in cleartext as result of a query. How can I do that?

You could use a view that excludes the SSN column or maybe use the DBMS_OBFUSCATION_TOOLKIT package.

File sizes explodes after removing hidden information

After removing hidden content in Acrobat Pro X (Tools/remove hidden content or Tools/sanitize) the file size increases, up to 10x (2 MB -> 20 MB). Save as optimized PDF only partly reduces the problem, file is still 3-4x the initial size. Document was created with Adobe PDF writer, but this problem occurs in principle also with other PDFs. Bug? Necessary? Workaround? Any help is appreciated. Thanks in advance!

Any one found a solution to this problem?
I'm having it too, acrobat xi pro 11.0.10...
Original file size before cropping ~27MB
Same file saved as optimized PDF before cropping ~12MB
Original file size after cropping ~27MB
Same file saved as optimized PDF after cropping ~12MB
Original file saved as some other file name after removing hidden information ~60MB
Same file saved as optimized PDF after cropping AND after removing hidden information ~60MB
What on earth is going on?

Collecting Sensitive Information Via a PDF Form

I have a client who is bound and determined to have a form on his website that collects sensitive information. Is there a way to create a PDF form that users can download, fill out, and submit the information securely? Since the data will be on the Internet it must be encrypted and send via a secure server (https). Does acrobat.com provide this functionality?
At first I was going to develop a simple webform hosted on a secure server, but I think this data should be encrypted.
Any help or direction on this issue is much appreciated.

Hello there,
For information on the security measures taken by Acrobat.com, I encourage you to look at our Security page. Acrobat.com account information and document security are taken very, very seriously; we do use secure sockets layer (SSL) technology (which, you'll notice, translates to https in front of a URL at Acrobat.com), and all data is encrypted. Please read further on the Requirements and Security page for details.
I hope this information is helpful! Let me know if you need additional assistance.
Best regards,
Rebecca

Remove UWL information areas under preview

Hi UWL Experts
I need to remove some of the information which is shown when a preview of a workflow item is displayed like Attachments and You can also links.
This part is easily fulfilled by use of the ivew parameters; but is this possible to customize on work item level instead? Because I only need to remove these information from some of the items and not all?
Thanks in advance
Cheers
John

Hi Kai
Thanks for the input, we have some tasks form the backend which is actually does not contain attachments but are displayed in the portal as attachments.
I have looked into the standard uwl.webflow configuration and found an item called uwl.task.webflow is guess that this is the one which the rest of my tasks receive the standard configuration from; if I want to create a new set of settings for some specific tasks then I need to copy this ad add a new prefix like costumized.webflow and add this prefix to the specific task that I want to change?
From this configuration I can see that it is possible to remove links from the you can also section, but is it also possible to remove informations from the details display of items as well (in the same way as it can be controlled globally from iview parameters)?
Thanks in advance
Cheers
John

Stop prompting me to remove hidden information

Please advise. Thank you.

BUG - remove hidden information - Acrobat remove some visible/live text (in all Acrobat versions)!!!

hello
I need to check many pdf for hidden/clipped text and remove them. Acrobat can find this BUT have bug.
Acrobat mark some live visible text and this is problem if you click "remove" button.
Here is evidence (6):

It was strange in my copy of DC, but I selected the Redact tool and then remove hidden information. I highlighted the hidden info in both files, but then backed out, not doing the remove. When I tried again, the remove hidden tool was blocked. When I actually did the removal, those items were missing as you mentioned. I am not sure why they were listed as hidden since they were indeed visible. I am not really helping answer the problem, but confirming your results.
Also, if you select remove hidden information when closing the document, you lose these fonts characters just as when using the Redact tool. I would agree that this is indeed an issue for a bug report. An earlier post provided the bug report link and I would suggest using it.

Remove Hidden Information

Hi! I am using Adobe Reader XI and can't find the QuickTool menu on teh right side of the document. I need it because I want to use the command Remove Hidden Information from a PDF file which keeps on giving me the error code 135 whenever I edit it and try to save it. I tried to save it under a different name but didn't help! I've read in the forum to try using the Remove Hidden Information, but didn't find it Any help will be appreciated.

May be that this function is not available in Adobe Reader.

My computer was used by someone else how can i remove their information for mine

my computer was my wifes old one and her iphone information is on here so i cant connect mine how would i remove her information so i can start clean with my own

The right way to do that is to copy your iTunes Library - the one that you used to sync your iPhone - to your wife's old computer.
The way it works is that your computer's content is transferred to the iPhone. So you need to start with a computer that already contains the information that you want to transfer to the iPhone. Or, simply restore the iPhone and configure it as a new device.

Remove hidden information without converting to RGB

I'm preparing a PDF for one-color printing, and it has some color data off the page that's messing up our prepress process. So I ran "remove hidden information" to cut that data out, but it converted the entire file from CMYK to RGB. I obviously need the file to stay CMYK (getting it down to just K was the whole point). Is there any way to remove cropped/overlapping data without converting to RGB?

You might try running the Preflight single fixup under Pages to "Remove page objects which are completely outside of page area" instead.

"Remove Hidden Information" not functioning properly after crop

Hello all,
I often print multi-page MS Visio documents to PDF, then edit them in Acrobat Pro XI. I have found that since the most recent update of Acrobat Pro XI, when I crop a page, then select "remove hidden information," it only removes text information, and not all the information that is cropped. For example, if I have a box filled with text that is partially cropped, and I select "remove hidden information," the portion of the text that is cropped is removed, but the entire graphical portion of the box remains and can be seen if the file is "uncropped." Is there a solution for this problem? It seems like it should be easy to remove all the previously-visible data that has been cropped, and in the past, I have been able to do so, but I can't seem to any longer.
Thanks in advance.

I wouldn't expect it to remove part of a graphic in general. I haven't compared results.

Working with sensitive information in Help

All,
I'm looking for advice on how to deal with including
"sensitive" information in Help. Specifically, there's a request to
add information in Help on how our software's security settings are
handled (i.e. setting up a user's security settings to access
certain areas or perform certain functions within our software).
Regarding access, what's the best or most recommended method
of limiting this information to only certain users (i.e. our
customers' system administrators), without their end users seeing
it? The issue would be a "regular" user accessing this information
and finding a way of changing their own settings without the
permission or consent of their sys admin.
The most immediate idea would be to maintain separate "Admin"
and "End User" versions of the help system. This wouldn't be much
work on my end, but I'm not sure if long-term there's interest in
having different versions floating around, and of course if a savvy
user finds where the admin-oriented help is located....
I'm open to any and all ideas. FWIW, we use RH 7 and our Help
is in Microsoft HTML (.chm) files.

Thanks for the link!
I'm not sure what support there might be in my office for
moving to a different Help format, but increased security is
probably a good selling point for a different format like WebHelp.
