This plugin will be ideal for protecting vanilla (raw) PDF embedded on web pages that use a copy protection solution like the ArtistScope Site Protection System (ASPS).
ASPS provides the most secure copy protection for all media displayed on web pages… except for PDF, because while PDF is unencrypted and normally opens using Adobe Reader resources, the embedded reader will always provide save, print and copy options in its toolbar.
But with this plugin, those toolbar options can be removed, thus making it possible to copy protect PDF on ASPS web pages.
