Obfuscation is the process of making information unclear, thereby making it more difficult to alter or copy.

Obfuscating data, similar to encoding it, can be reversed if the person accessing it has the algorithm used to make the transformation. Obfuscation, too, does not require a key and indeed it can be manually undone albeit with considerable effort.

Obfuscation, also called beclouding, creates an obstacle for the holder of the information by preventing them from understanding it. It is a barrier commonly used to protect a software’s source code, namey to avert its duplication.


“The source code for proprietary software is almost guaranteed to be obfuscated since product duplication is rampant in the technology sector. This is especially when dealing with jurisdictions where intellectual property rights are lacking.”
