In the last decades, the number of digital devices (Yeh and Xing, 2016) has grown exponentially. Digital devices range from mobile phones, computers, car electronics and the like including any instruments containing digital components of evidentiary value. Since these devices are commonly used by criminals, they can be helpful for solving crimes by utilizing the digital evidence that can be extracted from them. Nowadays, criminal investigations almost always have a digital component (Casey, 2011; Garfinkel et al., 2009; Baggili et al., 2013). The arena of digital evidence in forensic laboratories has grown rapidly and its use in court is routine. In this chapter, we explain the different aspects of digital evidence ranging from quality assurance to alternate types of digital evidence.
