Clinical Decision Support System

However, for example, an attacker trying to break a licensing routine would first focus attention on Strings having to do with licensing to locate the appropriate spot of code.
It will not prevent an absolute hacker from deciphering the conversion and seeing your data. Only specified strings will be encrypted/obfuscated.
Since Strings can provide useful clues for anyone trying to reverse-engineer your code it makes sense to protect your string data from spying eyes. You have choice to apply a cryptography method for the string encryption. You may select all strings to be encrypted. The string encryption function allows you to select literal values of string data type to be encrypted. Skater can make this more difficult by encrypting the strings in your .NET assembly. This is done by inserting a decryption routine into the assembly and calling the decryption code at runtime to return the original Strings.Also you may mark some specific strings to obfuscate.

Also, the control flow is critical to determining the intent of the program. Another technique is a technique called the bogus function calling graph. In this case, the obfuscated version is influenced by the dynamic analysis, which causes the obfuscated calling relationship to change. This change is very effective because it enables reverse analyzers to face more abstract functional units. COOPS starts from the semantics of the program and transforms it into an interfunction call flow graph. Because of this, the original version is difficult to interpret with the human eye. This method changes the called function before running the target program. Another technique is the COOPS (Control Flow Oriented Obfuscation Scheme), which changes the control flow structure of the program. If the control flow is not understood, it is difficult to determine the true content of the message.However, this method is easily susceptible to dynamic analysis of the program. Moreover, it improves the resistance of the software against similarity analysis techniques.
It is important to remember that obfuscation algorithms affect the program's semantics as well as the calling relationship.
