Today PDF document almost has been the most
popular format in our daily life and work. As we all know, Portable
Document Format (PDF) is a file format used to represent documents in a
manner independent of application software, hardware, and operating
systems. Each PDF file encapsulates a complete description of a
fixed-layout flat document, including the text, fonts, graphics, and
other information needed to display it. It is really a convenient file
to use, save and read.
However, in such an advanced IT times, our PDF files
would be copied, distributed freely without the permission of the
source author, which could infringe the author’s right. You’d like to
share some of your PDF files online. Meanwhile, you’re worried about
they maybe copied and distributed without your permission. Sometimes,
although your files are encrypted for security, most freeware or open
source PDF readers ignore the permission "protections" and allow the
user to print or make copy of excerpts of the text as if the document
were not limited by password protection, even without removing the
password. It really furies the authors. We wonder how could the owner
protect their PDF files effectively?.
