i know we can use password security to prevent others from copy , edit and save the secure documents , but the "save as" button still is open , and others can use the button to download the secure documents , is there any way to disable the "save as" button ? or any 3'rd party provide the plug-in ?
Even if you gray out the menu, the PDF will still be located on the system (i.e., if the user right-clicks and downloads from the browser) and they can copy it from the Temp folder as often as they like. This is just the standard way that Windows interacts with web browsers.
To prevent these loopholes, PDF files can be integrated with Digital Rights Management technology. For more information on this you can visit:
