SYSTEM, DEVICE, METHOD AND COMPUTER READABLE RECORDING MEDIUM FOR DETECTING MANIPULATION OF A MOBILE APPLICATION FILE

摘要

The present invention relates to a device for detecting the manipulation of a mobile application file, which is capable of detecting whether or not of the manipulation of a mobile application file, based on whether the mobile application file including a signature (signature information) is repackaged. More particularly, the device comprises: a receiving unit for receiving a request from a user terminal; and a providing unit for providing the user terminal with a mobile application in response to the request. The mobile application includes an application signature information extraction unit for extracting first signature information from the mobile application and storing the first signature information in the user terminal, in the initial execution or initial installation of the mobile application, and extracting second signature information from the mobile application in the re-execution of the mobile application; and a signature comparison unit for comparing the first and second signature information and determining whether to execute the mobile application, based on the comparison results.
