Digital Evidence – How It’s Done

Computer documents, emails, text and instant messages, transactions, images and Internet histories are examples of information that can be gathered from electronic devices and used very effectively as evidence. 

For example, mobile devices use online-based based backup systems, also known as the “cloud”, that provide forensic investigators with access to text / messaging app messages and pictures taken from a particular phone. These systems keep an average of 1,000–1,500 or more of the last text messages sent to and received from that phone.

In addition, many mobile devices store information about the locations where the device travelled and when it was there. To gain this knowledge, investigators can access an average of the last 200 cell locations accessed by a mobile device. Satellite navigation systems and satellite radios in cars can provide similar information. Even photos posted to social media such as Facebook or Instagram may contain location information. 

Photos taken with a Global Positioning System (GPS)-enabled device contain file data that shows when and exactly where a photo was taken. 

Investigators can collect a great deal of history related to a device and the person using it!
