The rules of digital evidence include admissibility, authenticity and reliability, best evidence, direct and circumstantial evidence and hearsay. Digital evidence must be thoroughly checked that it abides by these rules to be admissible in court.

There are many sources of digital evidence, but for the purposes of this publication, the topic is divided into three major forensic categories of devices where evidence can be found: Internet-based, stand-alone computers or devices, and mobile devices.

Potential evidence: Handheld devices such as mobile phones, smart phones, PDAs, digital multimedia (audio and video) devices, pagers, digital cameras, and global positioning system (GPS) receivers may contain software applications, data, and information such as documents, e-mail messages, Internet browsing history.

Akin to categories of evidence in the “traditional” forensic sense, digital equipment and their attributes can be categorized into class and individual groups.

Digital evidence can be defined as the information or valuable data stored on a computer or a mobile device that was seized by a law enforcement organization as part of a criminal investigation.
