Mobile forensics refers to digital evidence from mobile device as compared to data from computers.
The mobile forensics includes getting data and evidence from not only mobile phones but also PDAs, tablets and GPS gadgets. Some of the information that can be used as evidence in these devices is calendars, notes, videos, contacts and photos and others including MMS and SMS. The currently leading mobile forensic tool is called Cellebrite and can be found here.
The use of mobile forensics is still relatively new but it is slowly seeing a growing demand as there is more use of these devices all over the world. There are many people who continue to buy smart phones, and tablets as their everyday communication devices.
This method still has many technical challenges for example tracing where the call was made, it is not exactly easy to say that the call was made from that exact phone at that particular place due to the reason that the sim-card can changed from one phone or gadget to another. The way the phone is being used also continues to change.
With all these challenges, the retrieving process becomes a prolonged and tedious process since there is need to use different tools for this job. This therefore also calls for extensive and thorough training of the forensic examiner. The training will help train the examiner on how the different tools reveal and retrieve information and how is keeps the forensic evidence.
The forensics examiner ensures that the information in this gadget which can be used as evidence is retrieved so as to help in investigations and can also be presented in court as evidence. In the beginning, the evidence was retrieved using the same method as that of the computers but this became challenging since it was taking more time.
Mobile forensics is mainly used in law enforcement but also used in military intelligence, civil and criminal defense, private investigations, corporate investigations, and also useful in electronic discovery. When conducting the mobile forensics there are different areas that are looked at, these include the internal memory which is mainly the flash memory.
The examiner will also look at the service provider logs which involve looking at the call details and also the text messages; these are retrieved through wireless carriers. They will also look at the external memory which is basically getting information from SD and SIM and memory sticks.
The mobile forensics follows a particular process. Firstly, the device has to be seized, then secondly is the retrieving of data or the needed evidence, then finally there is the analyzing of the information to ensure that data retrieved can be useful in the case.
The use of mobile forensics can be a long process but what is important is getting the most important evidence that can help in the case and also help in solving the case. The mobile forensics is fast becoming important in court cases, since it has come up with evidences that have been used in courts to solve cases. The mobile forensics is still relatively new but also very vital in law enforcement.
