As many people carry their own smart phones and use them for various purposes, hackers’ interests move on toward developing smart phone hacking techniques. Among them, private information stealing becomes one of main topics because the information can be used for subsequent attacks such as smishing. For detecting such smart phone applications, some tainting analysis techniques are proposed to tag important information for tracking the tagged information. One of such evading techniques is to use a screen capture. In this paper, we showed how traditional steganography does not work for this purpose.
