In its application, Apple describes a means of securing code using
either a specific hardware address or read-only memory (ROM) serial
number. Apple also talks about securing the code while interchanging
information among multiple operating systems. Mac OS X, Windows and
Linux are called out specifically in the filing.
I'd normally suggest finding prior art for this, since its a technique
that's been in use for decades, at least, but in this case I'm quite
happy to see the whole field become a morass of patents.
"This invention relates generally to the field of computer data
processing and more particularly to techniques for creating tamper-
resistant software," Apple says in its patent filing. Specifically,
Apple refers to the technique of "code obfuscation," in which
software makers employ techniques that make it harder for those
using
debuggers or emulators to figure out how a particular block of code
is working.
Will they never learn?
