Abstract: An electronic device configured to perform forensic analysis on a target device includes a data extractor, an emulator, and a user data converter. The data extractor obtains, from the target device, a source file of at least one of applications installed on the target device. The data extractor obtains, from the target device, user data generated according to the least one of the applications being executed in the target device. The emulator emulates an execution of a target application installed based on the obtained source file. The user data converter converts the obtained user data having a data structure according to a database scheme of the target device into converted user data having a data structure according to a database scheme of the emulator. The emulator emulates the execution of the target application such that the target application operates using the converted user data.
