A Quick Review of Ways to Secure Adobe PDF Files

An Adobe PDF File is an easily accessible, highly portable and certainly more secure way of sharing important information with clients and colleagues. If you are sharing sensitive data such as litigation matters or corporate information, you might want to ensure that your Adobe PDF file is completely secured and cannot be accessed by unauthorized parties. In fact, Adobe Acrobat realizes that users might use PDF files to share valuable data and offers you more than one way to secure your files. We will quickly take a look at some of the commonly used techniques to secure Adobe PDF files including recovery methods that allow for a quick pdf repair so that there is no loss of the sensitive data contained in the files.

Typically, Adobe Acrobat makes use of the security features provided by operating systems such as Windows XP to secure the PDF files. Some of the more commonly used methods are -
" Using password encryption: You can secure the Adobe PDF file by adding a password and setting restrictions on being able to carry out certain functions. For example, the password can be used to restrict printing, editing and even opening of the PDF file. In other words, only those who know the password will be able to use these functions. If you know the password but are still unable to open the file, it is possible that the file has been damaged. You may then need to carry out a pdf repair before you can again access the file.
" Saving the PDF file as a Certified Document: The document author can restrict the changes being made to a PDF file. The author can specify what can and cannot be changed in the file, and add a certifying signature that will ensure that no person other than the author can make the changes.
" If you would like to send PDF files as an attachment via e-mail, you should use security envelopes. Sometimes, these PDF files do get corrupted in transit but using good recovery tools, you should be able to conduct a pdf repair and restore the data in the file.
" Using server-based policies: If you would like to allow others to access certain PDF files for a limited time period, you could use Adobe server-based security policies. In fact, if you are planning to enforce these security policies for a large batch of PDF files, you can use the Batch processing command and simply automate the steps.
" Before you proceed with securing a PDF form, you should first remove all the content that could be considered sensitive. Else, someone could make changes in this content and compromise the integrity of the document. If any form fields have to be filled in or signed, you may want to set the properties of the form fields to read-only so that no one can make any modifications in them.
" PDF files do become corrupted due to hardware or software failures and if a pdf repair is not carried out in time, you could lose valuable data. You should secure the data in an Adobe PDF file by knowing how to use third-party tools such as Advanced pdf repair from DataNumen to scan and recover data from the damaged files.
