USER TERMINAL TO DETECT THE TAMPERING OF THE APPLICATIONS USING CORE CODE AND METHOD FOR TAMPER DETECTION USING THE SAME

摘要

The present invention relates to a user terminal for detecting tampering of an application program using a core code, and a tamper detection method using the same. According to an embodiment of the present invention, the user terminal comprises: a communication portion for transferring information of the user terminal and information of the application program to a certificate server in a platform level or to a neighboring device paired with the user terminal if the installed application program starts, and receiving an original core code of the application program and the code property information from the certificate server or the neighboring device; a code recognition portion for recognizing the core code of the application program installed in the user terminal by using the received code property information in the platform level; and a tamper detection judgment portion for judging whether a tamper detection exists or not by comparing the original core code of the received application program in the platform level with the recognized core code. According to the present invention, it is possible to protect the user terminal from the tamper detected application program by detecting whether the tamper detection is applied to the application program. In addition, the present invention enables to overcome uppermost limit of a tamper detection method in a level of the application program, which is possible to detour or avoid, by detecting the tamper detection of the application program in the platform level.
