The History of Digital Forensics

Before the 1980s, crimes involving computers and digital devices were dealt with using existing laws. So, the field of digital forensics is relatively new. While its history may be short, it is quite complex.

As the years went by, the range of digital crimes being committed increased, but it was not until the 1980s that federal laws began to include computer offences. Canada was actually the first country to pass legislation in 1983, followed by the US Federal Computer Fraud and Abuse Act in 1986.

The fact that computer and digital crimes grew so much during the 1980s and the 1990s caused law enforcement agencies to start making specilised groups to deal with the technical aspects of the investigation. For example, the Computer Analysis and Response Team that the FBI formed in 1984.

Throughout the 1990s there was a high demand for these new investigative resources, this lead to the creation of regional and even local level groups to help handle the load. But, it was not until 1992 that the term “computer forensics” was actually used in academic literature.

Since the year 2000, a lot of people and agencies have written and published guidelines for digital forensics. A European lead international treaty, the Convention on Cyber crime, came into force in 2004 with the aim of reconciling national computer crime laws, investigative techniques and international co-operation.

The issue of training also received some attention. Companies, such as forensic software developers, began to offer certification programs, and digital forensic analysis was included as a topic at the UK specialist investigator training facility.

Since the late 1990s digital devices have become available everywhere, basically everyone has a phone or some kind of digital device. Devices have advanced way beyond simply communicating, they are great forms of information, even for crime not usually associated with digital forensics. However, digital analysis of phones has lagged behind traditional computer media, mostly because of problems over the ownership of the devices.

The complex field of digital forensics will always have unresolved issues. Many issues will include; increasing size of digital media, the wide availability of encryption to basically everyone, the variety of operating systems, increasing number of people owning multiple devices and lets not forget the legal limitations on investigators.
