VIATRA Model Obfuscator

Obfuscate: To deliberately make more confusing in order to conceal the truth (http://en.wiktionary.org/wiki/obfuscate)

The VIATRA Model Obfuscator is a small utility for obfuscating structured graph-like models (e.g. XML documents, EMF models) by altering all data values (such as names, identifiers or other strings) in a way that the structure of the model remains the same. Two data values that were identical before the obfuscation will also be identical after it, but the obfuscated value computed based on an input obfuscation string will be completely different (e.g. “Info1” may become “K18DWVQ=”).

For more details, read the wiki page.
