Digital forensics is a branch of forensic science which involves the recovery and investigation of material found in digital devices, often in relation to computer crime. Digital forensics cover investigation of all devices capable of storing digital data and therefore the technical aspect of an investigation is divided into several sub-branches, relating to the type of digital devices involved, i.e. computer forensics, network forensics, forensic data analysis and mobile device forensics.
Electronic discovery or “e-discovery” is the exchange of data in electronic format between parties in civil or criminal litigation. The process is essentially controlled by attorneys who define what data should be produced based on relevance or withheld based on claims of privilege.
