Abstract
Tampering with pieces of software is inhibited. The obfuscation of a software image so as to becloud the comprehension of hackers in reverse engineering pieces of software comprising the software image is provided. A process of verifying whether the pieces of software together constitute a software package that requires protection from tampering is also provided. Another process for determining whether the hardware resources, such as the central processing unit or the cache memory on a computing machine, belong to a class for which inhibiting software tampering is possible, is also provided.
