One new article link has been added to our Related News page. BBC News published an article titled Battery power alone can be used to track Android phones.

Android phones can be tracked without using their GPS or wi-fi data by studying their power use over time, a study has found.

A smartphone uses more power the further away it is from a cellular base and the more obstacles are in its way as it reaches for a signal.

Additional power use by other activities could be factored out with algorithms, the researchers found.

They created an app designed to collect data about power consumption.

Related News: Naked selfies extracted from ‘factory reset’ phones

One new article link has been added to our Related News page. BBC News published an article titled Naked selfies extracted from ‘factory reset’ phones.

Thousands of pictures including “naked selfies” have been extracted from factory-wiped phones by a Czech Republic-based security firm.

The firm, called Avast, used publicly available forensic security tools to extract the images from second-hand phones bought on eBay.

Other data extracted included emails, text messages and Google searches.

Experts have warned that the only way to completely delete data is to “destroy your phone”.

Most smartphones come with a “factory reset” option, which is designed to wipe and reset the device, returning it to its original system state.

However, Avast has discovered that some older smartphones only erase the indexing of the data and not the data itself, which means pictures, emails and text messages can be recovered relatively easily by using standard forensic tools that anyone can buy and download.
