* Windows dependencies will be eliminated and the code will be platform independent
* Multi-threading will be added 
* Various different type of data can be extracted

* More vulnerability check, memory and CPU usage analysis (Performance Profiling)
* Further experiments with different types of disk images will be done
* Different JPEG images might have different type of information, include various types of jpeg files
