So... a built in back door has been compromised ?
Samsung's vaunted Knox security kept their passwords in a clear text file in an external Library in an unencrypted section of the operating system that anyone could easily find. Now we find they are keeping the images of their "secure fingerprint" comparison scans in a similar insecure folder in a Library that anyone can find and that any app or non-privileged user can access. WOW! That's considered security? They did not even try to HASH them.
