Everyone is aware of the fact that mobile applications have become omnipresent. As the most frequently accessed features available in a handset, they are powered to provide an immense amount of communication abilities, channelized functionalities, and an essence of better productivity. Generally,…
Smartphones can be tracked by battery use
If you thought that someone can trace you, using GPS or Wi-Fi on your smartphone you were right. So, turning off GPS and Wi-Fi can solve the problem. Actually, no! One study found that your phone can be traced by battery use! The explanation is very simple. Your phone uses more power if it is further away from a cell tower. With a certain algorithm, researchers can trace you, with the same level of accuracy as with GPS.
Dan Boneh, Yan Michalevsky and Aaron Schulman, from the Stanford University, made an Android app that collects data about power consumption. It doesn’t require permission for location providers such as Wi-Fi or cellular or for the GPS. The only permission, this app requires is for network connectivity and the power data. These permissions are very common on Google play, at the moment there are 179 apps that require this permission! Listening to the music or taking voice calls, drain the battery, but the app for tracing your phone can discount this data!
Although this app was made just for research purposes, maybe the similar apps are already among us! If you remember, a tiny app for flashlight, required permission for accessing your personal data. So, maybe we have been traced already. Modern smartphones have many sensors (gyroscopes, accelerometer and etc.), which have been used for providing more options to the user. On the other side, they can be used for other purposes, like tracing your location! At the moment this affects only Android phones. IPhone is much safer. Apple even invested several million dollars for improving the protection on new phones!
