'''Obfuscation''' is a code transformation technique used to make source code difficult to read and understand while preserving its functionality. This process typically involves renaming identifiers, restructuring code, or inserting misleading elements to obscure the original logic. Obfuscation is often used to protect intellectual property, prevent reverse engineering, or secure sensitive logic in software. While the transformed code remains executable, it becomes significantly harder for humans to analyze, ensuring that key implementation details are concealed without altering program behavior.

In addition to obfuscation, '''anonymization''' (also referred to as ''identifier anonymization'' or ''pseudonymization'') focuses on removing or replacing potentially sensitive naming information—such as customer names, project codenames, or personally identifiable data—while keeping the overall structure, control flow, and intent readable for legitimate reviewers. Whereas obfuscation primarily seeks to hinder reverse engineering by making the logic opaque, anonymization emphasises privacy and confidentiality by stripping away semantic context from identifiers.
In addition to obfuscation, '''anonymization'''  
 
Both techniques are complementary and are frequently combined in practice. Typical motivations include:
 
* '''Intellectual‑property protection''' – Obfuscation hides proprietary algorithms and data structures from competitors.
* '''Safe code sharing''' – Developers can supply code snippets to external consultants or open‑source communities without exposing confidential business knowledge.
* '''Security hardening''' – Obfuscation complicates automated exploit generation, while anonymization removes hints that could facilitate targeted attacks.
