Common Mistakes

applying obfuscation to mobile app code

Heavy obfuscation made the JavaScript file impossible for Ilan to read, even though it still ran perfectly.

Common collocations
  • code obfuscation
  • obfuscation tool
  • JavaScript obfuscation
  • binary obfuscation
Synonyms
  • minification

    the reverse activity — turning compiled code back into something readable

Grammar Patterns

code obfuscation

obfuscation of [code/binary]

Usage Note

Common Mistakes

The programmer used obfuscation to fix the bug.
The programmer used obfuscation to protect the app from being copied.

Synonym discussion

Sense: noun/1

All four words describe ways of avoiding plain truth, but they differ in scope and register. 'Obfuscation' is the broadest: any deliberate use of confusing language to stop people understanding a situation, from a politician's reply to a contract clause. 'Evasion' is narrower and more personal — it focuses on dodging a specific question, often by changing the subject rather than by piling up vague words. 'Obscurantism' is the most academic; it typically describes a whole habit or movement (a scholar's whole style of writing, for example), not a single statement. 'Doublespeak' is more informal and journalistic, and points at language that twists meaning so a bad thing sounds good — calling layoffs 'workforce optimisation', for instance. A minister who buries an answer in vague phrases is engaging in obfuscation; one who simply refuses to address the question is committing evasion.

Etymology

LatinLate LatinEnglish

Comes from Latin 'obfuscare', meaning 'to darken' (built from 'ob-', meaning 'over', and 'fuscus', meaning 'dark'). The word entered English in the early 1500s with the literal sense of dimming or shadowing something physical, and gradually shifted to its modern figurative meaning — clouding the mind by clouding the language. The computing senses (online privacy and code) are recent extensions of the same image: instead of darkening sight, they darken data or instructions.
