We've all heard of the dreaded smudge attack: when a not-so-do-gooder gets a hold of your device and cracks your lockscreen combination using the evident fingerprints on the screen. Of course, this can easily be prevented by simply wiping the screen after you unlock it, but not everyone remembers to do that. Now, though, thanks to an app called WhisperCore, you are basically required to wipe the screen before you can access your phone.
