Apparatus and method for detecting falsified application

PURPOSE: A device for detecting the forgery of an application and a method thereof are provided to determine the forgery of the application based on verification signature information, thereby accurately detecting a forged application. CONSTITUTION: A recognition unit(102) recognizes a diagnosis object application by extracting a recognition signature from a diagnosis object application and comparing the same with a recognition signature of a normal application. When the diagnosis object application is recognized, a verification unit(106) determines forgery of the diagnosis object application by extracting the verification signature from the diagnosis object application and comparing the same with the verification signature of the normal application. When the forgery of the diagnosis object application is determined, a blocking unit(110) blocks the diagnosis object application.
