A forensic investigation includes the practice of legitimately facts and shreds of evidence that are to be presented in a law court. A crime scene investigator is a person who conducts or responsible for collecting and safeguarding evidence from a crime scene whereby he/she collect and document physical proof, for instance, taking photographs of the wrongdoings in the scenes. (Fick, 2020)Notably, the computer files, emails, transactions, emails, instant posts, images and net histories are instances of data collected from automated devices to provide good evidence that is effective. The mobile phone uses a cloud backup system that provides the forensic investigator with viable data when accessed in the messages and photos taken from a specific phone. The systems can hold 1000-1500 or more of the recent texted messages and received them from that phone device.
Further, the portable device also stores data about the positions where the gadgets have gone and when it was a particular time. Investigators access an average of roughly two hundred cell phones accessed by mobile devices; this information can also be obtained from the satellite triangulation systems and satellite wirelesses in vehicles. (Hikmatyar & Sugiantoro, 2019). Pictures displayed to social media such as Facebook may comprise location evidence too. However, pictures snapped when the global positioning system can contain rich data that shows when and precisely the shot was taken.
There are well analyzed seizing procedure that needs to be followed for accurate smartphone devices, for instance, the device to investigated there needs to be switched off instantly, and battery detached to guarantee the smartphone preserves the location, call logs and stops the phone from being used, which could adjust the information on the phone and much more it may update and compromise data. Secondly, the cell phone should be kept in a faraday bag for isolation and prevent other blocking materials set, such as Wi-Fi, Bluetooth, airplane mode or other communication systems, that must be disabled. Lastly, the device should have a report written in it, which suggests which operation or information to be sorted for, for example, call histories, phone numbers, short messages or images. To avoid misleading information, the first information should be recoded well and the equipment.
Performances of the analysis are done on the data gathered in the laboratory to retrieve data. An analyst follows these steps; contamination should be prevented as much as possible from the crime scene, and in the laboratory, also digital evidence should be prevented from the collection officer. A copy of the evidence analyzed is kept in a clean device not to be altered in any way. The device should be isolated from other wireless devices and examined in the isolation chamber to be fully assured the devices can’t connect to any network and keeps information as clean as possible.
Consequently, the analyst uses the data to view data, hence retrieving the hidden data and restoring the files; also, the deleted files are visible, considering they haven't been overwritten by new data is helping information to the analysis. The internet, short messaging, websites, emails, timestamps and other encrypted information can be put together and provide a viable claim.
