Caller ID and spam protection apps let a user know who is calling even when the number is not on the user's contact list by using an online service to do the lookup. Users can also upload their and their contacts' names and numbers into an online service. This could allow potentially DoD sensitive data, such as names and telephone numbers, to be compromised.
