One way to find out:
  sudo apt-get remove libsc7_2.3.1

It will remove all that depends on the package as well. Before doing it, it
will ask if you are sure. Say no, or hit Ctrl-C, unless the package list
looks totally harmless to you.

Probably to make reinstalling faster. I usually do 
   sudo apt-get clean
as a part of my weekly(?) update routine, and it seems to keep them away.
Actually, my routine command (cut and pasted from the wiki page where I note
the changes) is
  sudo apt-get update && sudo apt-get dist-upgrade -u && sudo apt-get clean
