Intellectual Property Protection and Code Obfuscation -- Cont'd By Adnan Masood email this article to a colleague suggest an article Conclusion Source code is the biggest asset for any software enterprise, and its protection is critical. This article explained how we can protect code from being reverse engineered and falling into the wrong hands. This writing was aimed at introducing the technology which makes decompiled code difficult to be understood, and it included a brief discussion on virtual machines as it pertains to exposing the original source. And if it's of any consolation, decompilers don't reveal comments.
