Computers are getting more powerful, so the field of computer forensics must constantly evolve. If it’s easy to change computer data, how can it be used as reliable evidence? Many countries allow computer evidence in trials, but that could change if digital evidence proves untrustworthy in future cases. Some people say that using digital information as evidence is a bad idea. Lawyers can contest the validity of the evidence when the case goes to court. If detectives seize a computer and then start opening files, there’s no way to tell for sure that they didn’t change anything.
Many of the techniques detectives use in crime scene investigations have digital counterparts, but there are also some unique aspects to computer investigations.įor example, just opening a computer file changes the file - the computer records the time and date it was accessed on the file itself. The purpose of computer forensics techniques is to search, preserve and analyze information on computer systems to find potential evidence for a trial. Civil cases on the other hand deal with protecting the rights and property of individuals (often associated with family disputes) but may also be concerned with contractual disputes between commercial entities where a form of digital forensics referred to as electronic discovery (e-discovery) may be involved. Criminal cases involve the alleged breaking of laws that are defined by legislation and that are enforced by the police and prosecuted by the state, such as murder, theft and assault against the person. The most common is to support or refute a hypothesis before criminal or civil courts.
