Bog'liq DigitalEvidenceM obile devices: Although handheld voice transmission devices using radio transmission have been in use since the 1940s (the Walkie-Talkie), the first version of what we would now call a cell phone was not developed until the 1980s. Cell phone use around the world skyrocketed in the 1990s and hit 4.6 billion cell subscriptions by the end of 2009. Cell
phone and wireless technology has expanded
to include many types of mobile devices such as tablet computers and hand-‐held video games.
Once used only for voice communications, today’s cell phones are also used to take digital photos and movies, send instant messages, browse the web and perform many of the same tasks as a computer. Mobile devices allow criminals to engage in an ever-‐growing variety of activities and the devices keep track of every move and message. It is this tracking capability that turns mobile devices into key evidence in many cases.
Why and when is digital evidence used?
Digital evidence may come into play in any serious criminal investigation such as murder, rape, stalking, car-‐jacking, burglary, child abuse or exploitation, counterfeiting, extortion, gambling, piracy, property crimes and terrorism. Pre-‐ and post-‐crime information is most relevant, for example, if a criminal was using an online program like Google Maps™ or street view to case a property before a crime; or posting stolen items for sale on Craigslist or E-‐Bay®; or communicating via text-‐message with accomplices to plan a crime or threaten a person. Some crimes can be committed entirely through digital means, such as computer hacking, economic fraud or identity theft.
In any of these situations, an electronic trail of information is left behind for a savvy investigation team to recognize, seize and exploit. As with any evidence-‐gathering, following proper procedures is crucial and will yield the most valuable data. Not following proper procedures can result in lost or damaged evidence, or rendering it inadmissible in court.
