Personal information on 980 Japanese school children from 37 shools has been exposed through Google Maps. The children range from Kindergarden through High School. Teachers using Google maps have been exposing this data totally by accident and unknowingly. and the problem is two fold.
Problem number one is the default settings. Users assume they are the only ones who can access the data they are putting in but the data is publicly accessible. The default setting must be physically changed by the user for privacy.
Problem number two is even when the data is deleted, it is remaining visible for some time. One teacher deleted information on November 5th and it was still accessible on the online map several days later. It is all too easy to expose data today and we must all use special care in protecting our own privacy and the privacy of others we do business with.
