What does obfuscation mean?
Obfuscation is the act of making information, meaning, code, or identity difficult to understand, discover, or analyze. It commonly describes deliberate efforts to obscure a message or intention, such as the use of complicated jargon, indirect language, misleading presentation, or transformed code. The word can also have a technical meaning in computer security and programming, where obfuscation is used to make software harder to read, reverse-engineer, or tamper with. Although obfuscation can be associated with deception, it is not always dishonest: it may be used to protect privacy, intellectual property, security, or sensitive design information. Understanding the term is useful in discussions of language, law, politics, privacy, and software, where apparent clarity may conceal a more complicated purpose.

Where does obfuscation come from?
Obfuscation comes from the Latin verb obfuscare, meaning 'to make dark' or 'to obscure,' from ob- ('over' or 'against') and obscurus ('dark' or 'hidden'). English borrowed the related form obscure in the late 16th century, and obfuscation developed later as a formal noun derived from the same Latin root. Its relatives include obscurity and obscurely, all sharing the idea of concealment or lack of clarity.

How obfuscation is actually used
Usually formal or technical. It most often describes intentional concealment, although it can also be used more broadly for any process that makes something difficult to interpret. In computing, it commonly refers to making code harder to understand or reverse-engineer, without necessarily implying malicious intent.

Obfuscation is an active process of making something hard to understand, whereas obscurity is more often a quality of being unclear, obscure, or little known.
