Alexa/Google Home Forensics

Abstract

Amazon Alexa and Google Home are a potential source of digital evidence, partly because of their popularity. In additional, these devices are also always-on and listening to our day-to day conversations. Therefore, in this chapter we study Amazon Alexa and Google Home, the two most popular speakers. We will discuss how the voice service of these two devices work, what all information these devices potentially record, and where this information stored. Then, we will compare the accessibility of data stored locally on each device as well as data stored remotely associated with the specific device. The goal of the research is to see if the information collected by these smart devices could potentially have substantial value in a forensics investigation.
