What is the metadata?
In
general, the metadata describing the data in this case, photo or images, a
description of the image captured by the camera. This information is embedded
in the photo / image that we take, which is needed by the application of computers
to process the photo to make a better image.
At some
format image / photo, the information stored is complete, such as information
about ISO, Aperture, Flash, Lens Type, applications to process and this is very
dangerous.
The dangerous of Geotagging.
What is a Geotagging?
Geotagging
is the process of providing information or add a location (Latitude coordinates
- longitude and Longitude - Latitude) on a document or photo. This information
can show the exact location where the photo was taken. Smartphone devices such
as iPhone, Samsung, BlackBerry or iPad or Galaxy Tab or Galaxy Note, in most
cases have the ability to automatic add this information in the photos we take.

A lot
sophisticated camera that produced lately I've also added a GPS (Global
Positioning System) which can determine the coordinates of our position
accurately. It's just this kind of camera users generally have understood why
he bought the camera with GPS facility. While users of smartphone or tablets
are generally ordinary people, many are not aware of this problem. After they
taking pictures with a variety of styles, and then they post their pictures to
the Internet.
Ignorance
of many people about embedding location information in the photo could be bad,
if there are people who want to do evil. Only by using a simple application,
they can learn various things about our lives:
- Where we
live
- Anyone
who lives in our house
- Where
are the children going to school.
- Where
are the children of foreign language tutoring, tutoring piano and so on
- Where we
work and our habit of eating lunch or dinner.
- When we
left the house and were located where
Because it
all comes apart coordinate our positions, also comes with our time taking
photos and post them to Twitter or foursquare.

Prevention tips:
In order
to avoid certain application retrieve and transmit data about the location we
are, smartphone or tablet allows us to turn off this service.
iOS (iPad or iPhone)
On the
iPhone or iPad, try clicking the Settings menu, then click the sub menu: Privacy,
then there will be a choice of Location Services. If we click, it will show all
applications that require the location of where we are or do something. If the
Location Services option is turned on, then it could aplikasi2 know where we
are at any given time.
For example,
if we turn on the option Camera Location Services, at the time when we take photos,
then our location data in the form of Latitude coordinates (latitude) and
Longitude (latitude) will be stored along with other information in our pictures.
Later one day, if we use iPhoto to manage the photos, we can know our
photographs taken anywhere in the form of a map of the world.
BlackBerry System 10
On
BlackBerry 10, select the Settings menu, then select the sub menu Location Services,
in the More Info section, there is an option to turn off Location Services. If
it is turned off, then all applications that take advantage of the position we
were not going to take us another location data, including Maps.
If you
just want to turn off the service in a particular application, click "Go
to application permissions to set .....” will display all the applications that
use Location Services, click on the application and then turn off the option:
Location and GPS Location.

Android such as the Samsung Galaxy
Note 10.1
Select the
Settings menu, then select the Location Services, then turn off all wireless
networks User option and Use GPS satellites. However it will shut down all
services needed by other applications that require our position.
Unlike in
iOS or BlackBerry, to turn off the GPS facility on the particular application,
we should immediately turn off on the application, for example Camera: turn on
the Camera application, select the Settings menu in the app, then select GPS
Tag sub menu, select Off .
It is a
turn off Location Services on the examples of several types of Mobile Operating
System that is popular in the community , other models flavors taste pretty
much the same way , just looking at the Settings sub- menu and turn off
Location Services .
