Device And Data Acquisition Tools
This process involves not only acquiring the data from the device but also ensuring that the forensic image you’ve collected matches the file signature of the original . Below is a list of tools that can be used to perform the device acquisition process, verify an image, and collect network traffic .
Common Mobile Forensics Tools And Techniques
Data acquisition is the process of gathering information from mobile devices and their associated media. This process reduces the chances of data loss due to damage or battery depletion during storage and transportation. Mobile device identification is necessary at the beginning of the forensic examination. The identification process includes understanding of the type of cell phone, its OS, and other essential characteristics to create a legal copy of the mobile devices content.
There are many tools and techniques available in mobile forensics. However, the selection of tools and techniques during an investigation depends on the type of mobile device and its associated media.

Stage : Device Seizure
This stage pertains to the physical seizure of the device so it comes under the management and custody of the investigator/examiner. consideration should also be given to the legal authority or written consent to seize, extract, and search this information.
The physical condition of the device at the time of seizure ought to be noted, ideally through digital photographic documentation and written notes, such as:
- Is the device damaged? If, yes, then document the type of damage.
- Is the device switched on or off at the time of seizure?
- What is the date and time on the device if the device is on?
- If the device is on, what apps are running in background on the device?
- If the device is on, is the device screen accessible to check for passcode andsecurity settings?
Several different aspects of device seizure are described in the following as theyre going to have an effect on post-seizure analysis: radio isolation, turning the device off if its on, remote wipe, and anti-forensics
What Data Types Can You Collect From A Mobile Device
Students should understand data types before the collection of data from a mobile device. The common data types include contacts list, call log, SMS, images, audio, video, GPS data, and apps data. Also, both current and deleted data types can be extracted from a mobile device.
Service providers frequently use CDRs to improve network performance. However, they can provide useful information to investigators, as well. CDRs can show:
- The terminating and originating towers
- Whether the call was outgoing or incoming
- Who was called and who made the call
Almost all service providers retain these important records for a certain time. The forensic specialist can collect these records if he requires. However, the collection of this information depends on the policies of the concerned state. Every state has different laws in this regard.
Global Positioning System : GPS data is an excellent source of empirical evidence. If the suspect has an active mobile device at the crime scene, GPS can pinpoint his location as well as his criminal acts. GPS also locates the movements of the suspect from a crime scene to the hideout. Furthermore, it helps in finding phone call logs, images, and SMS messages. Presently, a GPS system includes 27 satellites in operation.
SMS: Text messaging is a widely used way of communication. Text messages leave electronic records of dialogue that can be presented in the court as evidence. They include the relevant information such as:

How Do You Gather Data From Mobile Devices
The data can be gathered from mobile devices in two ways, namely, physical acquisition and logical acquisition.
Physical Acquisition, also known as a physical memory dump, is a technique for capturing all the data from flash memory chips on the mobile device. It allows the forensic tool to collect remnants of deleted data. Initially, the received data is in raw format and cannot be read. Later on, some methods are applied to convert that data into a human readable form.
Logical Acquisition, or logical extraction, is a technique for extracting the files and folders without any of the deleted data from a mobile device. However, some vendors describe logical extraction narrowly as the ability to gather a particular data type, such as pictures, call history, text messages, calendar, videos, and ringtones. A software tool is used to make a copy of the files. For example, iTunes backup is used to make a logical image of an iPhone or iPad.

Stage 2 Data Acquisition
This stage refers to various methods of extracting information from the device. The ways of data extraction that may be used are influenced by the following:
- Type of mobile device: The make, model, hardware, software, and vendor configuration.
- Availability of a various set of hardware and code extraction/analysis tools at the examiners disposal: theres no tool that does it all an examiner has to have access to variety of tools which will assist with data extraction.
- Physical state of device: Has the device been exposed to damage, such as physical, water, or biological fluids like blood? Usually the sort of injury will dictate the information extraction measures employed on the device.
There are many differing kinds of data extraction that determine how much data is obtained from the device:
