Hackers can gain access to information on the smartphone using its battery. This was told by a group of researchers in the report on the Symposium on Privacy Enhancing Technologies.
The study involved experts from the University of Texas at Austin, the Hebrew University in Jerusalem and the Technion (Israel Institute of technology).
When using the smartphone energy consumption is influenced by such factors as touch screen applications and much more. All of this information can allow for a variety of data from the use of the “activity portrait” to the typed text.
It is noted that the reason for panic the study does not, as it is only a theory which is very difficult to implement.
