Protect Your PDFs
Courtesy of:

The next time you distribute a PDF (by email, posting on the Web, etc.), think first about what it contains. Anything sensitive? Or are there parts of the PDF — a logo sketch or one of your photographs, for example — that you don’t want floating around on the Internet?
Using Adobe Acrobat, you can apply a simple PDF password that prevents people from copying text and graphics or from printing. And when called for, you can even require a password to open your file.
In this short, easy-to-follow video tutorial, you’ll learn how to protect your files from tampering. Click on the image below to open a separate window with the video.
