Obfuscation is a programming technique in which code is intentionally obscured to prevent reverse engineering and deliver unclear code to anyone other than the programmer. Obfuscation is also applied to programs to ensure intellectual property (IP) protection through reverse engineering prevention.
Common reverse engineering techniques rely on function and code clarity when copying program code. Obfuscation creates ambiguous code, which makes reverse engineering difficult.
Slicing is the most common technique used for resolving obfuscated program mysteries, where portions of code are analyzed and simplified to determine program functionality.
An obfuscator is a programming tool that is used to transform readable code into ambiguous code without affecting code functionality.
