You can determine the location of a person using his smartphone battery
Scientists from Stanford University in conjunction with the Israeli company Rafael, has been developing in the field of military technology, proposed a new method for determining the location of a person using his Android-smartphone.
Unlike technologies that use the built-in GPS sensor data or Wi-Fi, access to mobile applications that can limit proposed by researchers method involves the use of information about the level of power consumption of the device. This information is available by default all installed applications on your phone.
During the experiments, it was found that minor variations in power consumption of the smartphone, which depend on the distance to the nearest cellular base station or the presence of nearby tall buildings, enable us to determine the route of the device owner. When this energy changes due to other causes, for example, a telephone call may be identified and filtered.
However, notable results demonstrate the technology, when it comes to a certain set of routes. Researchers previously collected data on energy consumption phones in seven different cases, and then compare these figures with the information obtained from a smartphone LG Nexus 4, which is moved by one of these routes. Able to correctly identify the route in 90% of cases.
Nevertheless, the study attempted to apply the development and in unfamiliar conditions and had some success. Study participant Jan Mikhalevsky representing Stanford University, said that the team plans to improve the accuracy of the methodology and noted that quite openly once again raises issues of confidentiality, and Android developers should pay attention to this problem.
Recall that in August last year, the same group of researchers reported that the gyros are built into most modern smart phones can be used as listening devices.http://szlifestyle.com/sz/2015/02/24/you-can-determine-the-location-of-a-person-using-his-smartphone-battery/https://i0.wp.com/szlifestyle.com/sz/wp-content/uploads/2015/02/sz_android_smartphone.jpg?fit=750%2C422https://i0.wp.com/szlifestyle.com/sz/wp-content/uploads/2015/02/sz_android_smartphone.jpg?resize=150%2C150TECH NEWSsecurity,smartphone,TechnologyScientists from Stanford University in conjunction with the Israeli company Rafael, has been developing in the field of military technology, proposed a new method for determining the location of a person using his Android-smartphone.
