Permissions in PDF file

Hi,

I have to generate PDF document using <cfreport tag without permission to print or save this file. I am using permissions attribute, but it does not work at all. Even if I specify permissions="" I can still copy and print this file.
For example,
<cfreport permissions=""
template = "../reports/ClippingLabelWithScann.cfr"
format = "PDF"
filename = "#tmp_file_name#.pdf"
overwrite = "yes">
still gives me all permissions. I have also tried not to save to the file but displaying it into the browser. The same behavior. I have all permissions.

Is anything here I do wrong?
