Manage location data in the pictures you take [privacy and security]

Location data


Here ' s a point of Security and confidentiality that many of us forget, yet is really easy to manage – geo-location data on the photos you take with your Android phone. Cameras digital modern who have a way to capture data that GPS (which mean that your phone or Tablet Android) can attach location data to images using the Exif (Exchangeable image file format) standard. The Exif standard attached tags to metadata of images, sounds and video to track things like titles of songs, video length and camera model. He also has a slot for the coordinates of latitude and longitude of your GPS receiver.


Fixing GPS metadata for the photos you take can be useful, and there are reasons people would want to do so. Have the date, time and location in an image, means never forget where and when you took it, and you can use services such as Panoramio to place your photos on a map overlay. Have a fixed location of an image has several fun and legitimate uses.


But many times we don ' t want anyone else to know the precise location of GPS in an image we ' ve taken. "little Timmy ' s first day at summer camp" would make a great image to share on Facebook or Google +, but we do not want some stranger to know where the little Timmy is sleep this week? ". He ' s a scary world, which plenty of people with bad intentions. No one will blame you if you err on the side of caution.


It is important, because it ' s apps not only who can access these data. Download a picture from your (or friends) of the albums online somewhere. After you have saved it, right click (Windows) and look at all the properties. If the image is geo - tagged, you ' ll get GPS coordinates in a few feet from where the camera was when it was made. There are even programs and Web sites that spit out the data of the location of the images, and not all that uses these are trustworthy. Fortunately, it is really easy to transform the location marking on outside.


You ' ll find a place in your application of camera settings (stock or a custom store the set of Googleapplication) that will say location or geo - tag. Poke a little, he ' s in different places according to your phone ' firmware s or the app you ' matter the use, but it ' s. When this parameter is enabled, dependent on your GPS coordinates will be stored with the image data. When he ' s offshore, will take place.


Take control of these kinds of settings and keep you safe on the Internet.
