This highlights the importance of not only collecting such digital evidence but also having up-to-date procedures for its proper handling, archival, and maintenance, particularly to ensure its suitability for presentation in court. Digital imaging tools, such as digital cameras, photo cd discs and image handling software, can be important assets to the police department as it gathers and presents evidence but, to ensure that evidence gathered is valid and will be accepted by courts of law, protocols should be followed to maintain its integrity and genuinity .

Simply put in all likelihood perhaps the most important evidence to be gathered in digital evidence collection today and for the foreseeable future exists only in the form of the volatile data contained within the computers ram. To counteract those computer-related crimes, computer forensics plays a very important role “computer forensics involves obtaining and analysing digital information for use as evidence in civil, criminal or administrative cases (nelson, b, et al, 2008). Computer forensics is the practice of collecting, analysing and reporting on digital data in a way that is legally admissible it can be used in the detection and prevention of crime and in any dispute where evidence is stored digitally. Digital evidence is different from physical evidence, in that a carefully protected image of a hard drive is as good as the original hard drive in the eyes of a court.
The ability to convince the court that digital evidence is worthy of reception into the criminal process is dependent on the qualifications and competence of the tendered expert, the skill and knowledge of the prosecutor in leading such evidence and the quality of the digital evidence itself.

Digital evidence and forensics computers are used for committing crime, and, thanks to the burgeoning science of digital evidence forensics, law enforcement now uses computers to fight crime digital evidence is information stored or transmitted in binary form that may be relied on in court. Enter digital hashing, or the hashing function, which may be the most effective tool yet for securing digital evidence think of the hash as a digital fingerprint, not of a person, but of the digital evidence.
Digital evidence analysis disc, hard drive, and digital tape in most instances, optical discs and hard drives are the only realistic options an important consideration is how much data to export john is the general editor for the “handbook of digital & multimedia forensic evidence” published by humana press john can be reached. The volume of digital evidence is only going to increase, and media is only going to proliferate – far better to be in front of the issue before storage and it becomes unmanageable what we lack is the ability to join up the evidence outside of borders or across force digital stores. Issues in preserving digital evidence digital evidence is defined as any evidence of a crime that is neither physical nor human, but, are electronic impulses and programming codes (1279 pg 29.
