I created an Indesign (CS6) document with hyperlinks and exported it as a PDF document (Export -> Adobe PDF (interactive)).
I made 2 versions of the document. 1 full version and 1 light version (here some parts of the document are made invissible by adding white blocks over parts of the text/pictures). When opening the light PDF document in Adobe Acrobat Pro 9, it is still possible to remove those blocks. What can I do to both keep the hyperlinks working and make it imposible to remove blocks or adjust the light document in any other way?
Hope someone can help me with this.
Thanks for your answer. With different (legal and illegal) programs you can (easily) remove passwords or change the document in a way so that it can be adjusted. I am afraid this is not the solution I am looking for.
Anybody else a different solution?
There is no absolute security for a PDF that has interactive features because flattening removes most of them.
Perhaps you should rasterize the light version in Photoshop and add new hyperlinks to that.
