Cell Phone Forensics is a growing industry, making it an ideal career choice for many people interested in both computers and technology. Your cell phone or other mobile device holds plenty of sensitive information within it. This includes text messages, call logs, GPS data, Internet usage, App usage and much more. The information contained within a cell can actually become lost or corrupted; whether by accident or not.
There are several types of mobile devices, which fall under the Cell Phone Forensics category. Smartphones, PDAs, smart phones, and “others” fall into this category. With so many different models and manufacturers, it is important to know which type of mobile device you have in order to properly begin your investigation. Some of the major differences include; specific operating systems (such as android), screen resolution, memory size, camera models, etc. You need to be able to properly access and work with the data that is on your cellphone or smart phone. These are just a few of the things to consider when researching the various different mobile devices.
Text message forensic examinations and deleted call logs are two of the most popular aspects of cell phone forensics. Text message forensics examine deleted text messages from a cellular device. This includes both incoming and outgoing calls; and deleted text messages. In order to recover all of the data from any cellular communication device, experts utilize various methods such as computer vision, file corruption, and pattern recognition.
Excluded call patterns and deleted data examinations are also very popular among forensic examiners. This process consists of gathering different pieces of information from one phone and deciphering it to come up with an accurate and reliable extracted information. Some excluded call patterns and deleted data examinations use a known template which is then used to extract the needed information from the other devices being examined. Experts in this particular type of examination will often collaborate or work closely with other experts in order to get the most accurate results.
Not only will mobile devices contain deleted text messages, but they can also contain photographs, videos, voice calls, and email messages. When performing a text message or picture forensic examination, experts must also know how to extract information from the digital files found on cellular devices. In many cases, photos and videos can be extracted by simply viewing the files on the device in question. However, depending on the device, certain file types may require the use of specialized software in order to extract the needed data. When it comes to retrieving deleted data from mobile devices, experts in this particular area of forensics are some of the most skilled professionals in the industry.
One of the most popular tools for digital evidence extraction is a digital camera. Digital cameras are usually equipped with special software that makes them uniquely suited to this particular type of examination. One of the biggest advantages of using a digital camera is that it is able to instantly capture any images or text messages without having to wait for the device to download the images or messages. Another tool used in this particular type of cellular forensics is an electronic reading device, commonly known as an EOD reader. This particular device is similar to an EID, which is an individual’s tax id number. It is generally located inside the device, making it nearly impossible to tamper with or delete.
Aside from the physical tools that are used in this particular field of investigation, there are a number of technological tools that can be used in this type of investigation. Among the most popular tools utilized by cell phone forensics experts is a cell phone logger, which can be used to determine the frequency of call records and can also provide information such as text messages and phone numbers associated with the call. Cell phone forensic software can also be used to determine the location of certain individuals using GPS technology. It is also possible to trace email accounts and discover the sender of emails, as well as trace text messages. Digital devices and computer programs designed to do trace telephone calls can also be used by these professionals in their investigations.
Cell phone forensics professionals are required to obtain proper authorization before performing any type of digital evidence recovery procedure. In the past, cell phone forensics examinations could not be performed unless a warrant was first obtained from a judge. Now, most state courts permit the examinations of cell phones that are within the property of a third party. This is done in an effort to prevent people from secretly recording people without their knowledge or consent.
