The Automatic Extraction System of Application Update Information in Android Smart Device

ABSTRACT As the utilization rate of smart device increases, various applications for smart device have been developed. Since these applications can contain important data related to user behavio rs in digital forensic perspective, the analysis of them should be conducted in advance. However, lots of applications get to have new data format or type when they are updated. Therefore, whether the applications are updated or not should be checked o ne by one, and if they are, whether their data are changed should be also analyzed. But observing application data repeatedly is a time-consuming task, and that is why the effective method for dealing with this problem is needed. This paper suggests the automatic system which gets updated inf ormation and checks changed data by collecting application information.
