Go to settings, lock screen, additional information, and you should be able to disable it in there.
When I go into Settings, the menu is:
Settings > My Device > Lock Screen
From there the menu is:
Screen security
Swipe options
- Lock screen widgets (clock or personal message options only)
- Phone shortcut
- Camera shortcut
- Unlock effect (eg. Ripple effect)
- Help text
- Wake up in lock screen
- Set wake-up command
There is no "Additional information" dialog in this menu.
The obvious section would be under "Lock screen widgets", but the only options there are:
General Settings
- Clock or personal message [display clock or personal message on lock screen]
Clock
Personal message
Personal message options
