Mobile Computing

February 5th, 2021

Mobile computing refers to the use of any kind of computer in a moving environment. The motion may be of the device itself, as in laptops, palmtops, wearable computers, and mobile phones; or it may refer to the dynamics of the computing process, as in digital cameras, podcasters and MP3 players. Mobile computing devices generally use wireless technologies such as LAN, Wi-Fi, GPRS and the more recently introduced MAN.

Mobile computing can be broadly classified into two categories – portable computing and mobility computing. Portable computing actually refers to wired communication. Portable devices themselves are movable, but in order to access them one needs to connect them to a network port. That means, portable computing devices can be carried to wherever there is a network port available. Mobility computing is also called simply mobile computing nowadays. This is true wireless communication. Not only are the devices movable, but they can also be accessed from almost anywhere. Today, portable computing is almost on the verge of extinction; mobile computing has made its foray into almost every aspect of human life.

The first usage of mobile computing devices was perhaps in vehicles. Speedometers were among the first devices to get computerized. Almost every modern vehicle has several mobile computing devices under its dashboard. Cell phones are another rampant proliferation of mobile computing today. Every single cell phone is a computer in its own right. With the advent of wireless technologies, it is also possible to access the Internet through cell phones. Blue tooth has brought cell phone users closer than ever before and has facilitated data transfer within a stipulated area. Another brilliant advancement in the field of wireless technologies is the Metropolitan Area Network, or MAN, which will allow vehicles and cell phones to remain in communication with each other forming a network probably much vaster than the internet.

Today, mobile computing is a boon to people on the move. It can be used for checking mails while in transit and even carry out transactions and businesses. Services like SMS (Short Messaging Service) and MMS (Multimedia Messaging Service) are targeted towards the younger generation to remain in contact with their colleagues and friends. During sports events, mobile networks keep users informed of the goings-on.

However, critics are concerned with the intrusion of privacy that mobile computing creates. Several members of the younger generation are turning into ‘gizmo freaks’ and becoming almost addicted to their mobile computing devices like watches and cell phones. Some of these devices which work on infrared technologies can also pose potential health risks.

Yet, mobile computing has become an indispensable extension of technology today. It is definitely here to stay.

Electronic Evidence Discovery May Shift To The Mobile Computer Forensic Specialist

February 5th, 2021

As the computing world advances and especially as the world of the wireless computing advances, there are certainly going to be instances where the services of a mobile computer specialist will be required.

The mobile arena now includes hand-held devices with comprehensive capability, in fact there are many more wireless units than desktops.The complexities of today`s wireless units such as iPods, iPads, Smartphones and tablet computers now have the same computing power of PC`s that were manufactured within the last decade. With cutting-edge technology such as infrared and bluetooth now integrated in to mobile computers, the advances in mobile computing are rapidly surpassing those of the desktop computer.

The hand-held device now includes a wide variety of units and can include video cameras, iPods,digital recorders or any hand held units.Mobiles may differ from the desktop computer in the way that they operate. The mobile computer forensic field now shifts from hard drive recovery to electronic evidence discovery of hand held units.

The mobile operating systems and hardware standards may change more frequently as new advances are introduced. New versions may be introduced several times within the product year, whereas computer software, may be revised annually or bi-annually. There are many different platforms in the wireless computing arena which makes the job of the mobile computer forensic specialist even more challenging and additionally, there may be variations within each communication technology. There are several variations of the 802.11 which is the standard used by all wireless networks. Shorter range wireless communication involves the use of Bluetooth, while within even shorter ranges, communication is handled by the infrared light waves.

Mobile computer forensics does not only involve mobile phones and the approach is not yet standardized due to the rapid advances and multiple operating platforms. The main reason for the state of affairs is that many manufacturers are pushing different standards in hardware, interfaces, operating systems and protocols. As a result, mobile forensics cannot be treated in the same way as static computer forensics, even though the concepts, may appear to be similar. The mobile forensic specialist job may rely less on technology and more on skills, procedures and problem-solving ability and the approach can be different.

Perhaps the most important forensic component of the mobile phone would be the Subscriber Identity Module card which is used to authenticate the user and verify the services. Alternatively, this information can be embedded in the phone. Forensic information may also be available in external Secure Digital cards that can be used by most mobile devices.

The mobile forensic field is primarily concerned with the acquisition of mobile phone data and there are tools, both hardware and software. Another challenge for the mobile forensic specialist is to keep up with the avalanche of changes in the mobile computing industry. Mobile forensic software may behind the curve with regard to the new mobile technologies and you should be aware of the various tools both forensic and non forensic that can be used.

The new burgeoning field of mobile arena is sure to offer satisfying available opportunities and challenges for the mobile computer forensic specialist.

The mobile computer segment that includes notebooks, netbooks, tablets and other hand held devices, now easily surpasses the desktop PC market in market size.
