String Obfuscation
* Encryption: Encrypt specific strings to prevent attackers from deciphering critical information.
* Obfuscation: Obscure the values of selected strings without altering their functionality.
Control Flow Obfuscation
* Bogus Function Calling Graph: Alters the calling relationships between functions to confuse reverse engineers.
* COOPS (Control Flow Oriented Obfuscation Scheme): Transforms the control flow structure of the program, making it difficult to determine the flow of execution.
Considerations
* Obfuscation only provides a layer of protection against static analysis.
* Obfuscation algorithms can affect the semantics and calling relationships of the program.
* Dynamic analysis techniques can potentially bypass obfuscation measures.
* Obfuscation improves resistance against similarity analysis techniques.
DDxHub is a concentrator that holds a lot of disease descriptions. It relies on the System knowledgebase to diagnose a health condition.
Differential diagnosis Hub is the System distinguishing of a particular disease or health condition from others.
