Hey,
I'm fairly sure this patent is referring to Apple's method of
encrypting certain binaries (Finder, Dock, etc.) which can "only" (I
think it's been cracked now?) be decrypted with the "Dont Steal Mac OS
X.kext" kernel extension (check out your /System/Library/Extensions
folder).
A very nice article on the subject can be found here: http://www.osxbook.com/book/bonus/chapter7/binaryprotection/
Perhaps you could implement something like this?

This may be slightly off topic, but does anyone know of any object
code obfuscators which will work with mach-o binaries (PPC and
x86)? I've looked around but haven't had much luck. The only
product even remotely related I've been able to find is a C/C++
source code obfuscator from stunnix (http://stunnix.com/prod/cxxo/overview.shtml
), which I assume won't much good in terms obfuscating the generated
object code.
Apparently Apple applied for a patent a couple years ago on some
object code obfuscation technology (http://www.macsimumnews.com/index.php/archive/apple_files_patent_system_and_method_for_creating_tamper_resistant_code/
). But if they've done anything with it, they haven't made it
public. Other than the somewhat irrelevant product from stunnix
above, I haven't been able to find any other third party commercial
or open source technologies.
