USING ACROBAT X PRO 243 Security Removing sensitive content Why remove sensitive content? Before you distribute a PDF, you may want to examine the document for sensitive content or private information that can trace the document to you. Such information can be hidden or not immediately apparent. For example, if you created the PDF, the document metadata normally lists your name as the author. You may also want to remove content that can inadvertently change and modify the document's appearance. JavaScript, actions, and form fields are types of content that are subject to change. Use the Remove Hidden Information feature to find and remove hidden content from a PDF. Use the Black Out & Remove Content tools to remove sensitive images and text that are visible in a PDF. Find and remove hidden content Use the Remove Hidden Information feature to find and remove content from a document that you don't want, such as hidden text, metadata, comments, and attachments. When you remove items, additional items are automatically removed from the document. Items that are removed include digital signatures, document information added by third-party plug-ins and applications, and special features that enable Adobe Reader users to review, sign, and fill PDF documents. To examine every PDF for hidden content before you close it or send it in e-mail, specify that option in the Documents preferences using the Preferences dialog box. 1 Choose Tools > Protection > Remove Hidden Information. If you don't see the Protection panel, see the instructions for adding panels at "Task panes" on page 9. If items are found, they are listed in the Remove Hidden Information panel with a selected check box beside each item. 2 Make sure that the check boxes are selected only for the items that you want to remove from the document. (See "Remove Hidden Information options" on page 244.) 3 Click Remove to delete selected items from the file, and click OK. 4 Choose File > Save, and specify a filename and location. If you don't want to overwrite the original file, save the file to a different name, location, or both. The selected content is permanently removed when you save the file. If you close the file without saving it, repeat this process, making sure to save the file. Last updated 10/11/2011

Removing sensitive content

Why remove sensitive content?

Before you distribute a PDF, you may want to examine the document for sensitive content or private information that

can trace the document to you. Such information can be hidden or not immediately apparent. For example, if you

created the PDF, the document metadata normally lists your name as the author. You may also want to remove content

that can inadvertently change and modify the document’s appearance. JavaScript, actions, and form fields are types of

content that are subject to change.

Use the Remove Hidden Information feature to find and remove hidden content from a PDF. Use the Black Out &

Remove Content tools to remove sensitive images and text that are visible in a PDF.

Find and remove hidden content

Use the Remove Hidden Information feature to find and remove content from a document that you don’t want, such

as hidden text, metadata, comments, and attachments. When you remove items, additional items are automatically

removed from the document. Items that are removed include digital signatures, document information added by

third-party plug-ins and applications, and special features that enable Adobe Reader users to review, sign, and fill PDF

documents.

To examine every PDF for hidden content before you close it or send it in e-mail, specify that option in the Documents

preferences using the Preferences dialog box.

Choose Tools > Protection > Remove Hidden Information. If you don’t see the Protection panel, see the

instructions for adding panels at “

Task panes

” on page

If items are found, they are listed in the Remove Hidden Information panel with a selected check box beside each item.

Make sure that the check boxes are selected only for the items that you want to remove from the document. (See

“

Remove Hidden Information options

” on page

244.)

Click Remove to delete selected items from the file, and click OK.

Choose File > Save, and specify a filename and location. If you don’t want to overwrite the original file, save the file

to a different name, location, or both.

The selected content is permanently removed when you save the file. If you close the file without saving it, repeat this

process, making sure to save the file.
