Obfuscation, software protection and software security.
According to Business Software Alliance statistics, four
out of every ten software programs is pirated in software
business, world wide. Global piracy rate has increased
40% over the past years and nearly $11 billion is lost.
This is definitely a clear threat for software producers and
thus to global economy. Over the years, several software
protection techniques have been developed, code
obfuscation is one of them and it is very promising. Code
obfuscation is a form of software protection against
unauthorized reverse-engineering. In this paper we
discuss software protection techniques in general and
provide a broad overview of known obfuscation
algorithms. We also address the issues related to
implementation of obfuscation algorithms. Finally we
propose JHide, an obfuscation tool kit for protection of
Java code. We conclude our paper identifying the need for
reviewing the performance of the algorithms as the future
scope of our work.
