Are embedded Fonts connected to the book id?

enibas · 07-18-2014, 05:48 PM

I have a weird question, but I cant seem to find an answer anywhere on the web...
I have finished designing an ebook (starting in InDesign (CS4) and finishing it in Dreamweaver) and decided to change the book-id to match its ISBN number as a last step. when i change the book id all embedded fonts – that worked well on all devices so far – were not working anymore. Why is that and how do i fix this? I searched every file, not finding one hint that fonts and book id are somehow related...? Any tips?
Fonts are encrypted via an xml-file but again, the code doesnt provide any connection to the book-id... I am absolutely clueless.

I don't remember the details, but it's highly likely the key used to obfuscate the fonts is book-id based.
