Abstract: Obfuscation is a low cost software protection
methodology to avoid reverse engineering and re engineering of
applications. Source code obfuscation aims in obscuring the source
code to hide the functionality of the codes. This paper proposes an
Array data transformation in order to obfuscate the source code
which uses arrays. The applications using the proposed data
structures force the programmer to obscure the logic manually. It
makes the developed obscured codes hard to reverse engineer and
also protects the functionality of the codes.
