Extra information about digital forensics

What is digital forensics?

It refers to the science and process of revealing visible and invisible data from the electronic memory devices. Such memory devices are used in computers, laptops, smartphones, feature phones, tablets, servers, CCTV cameras, and other electronic devices. The part of a device that stores memory may be built in or removable. In case of the latter, the memory system may connect to the device through a slot which can be inside or outside the device. It may be a temporary or permanent memory. Even though a temporary memory system does not keep record of data after it has been switched off, it may still have some secondary data different from the main data. The goal of this process is to investigate scientifically and collect all types of data present on a memory device. Advanced software and hardware solutions are used for this purpose.

The Purpose of This Investigation

This type of investigation is generally carried out when someone tries to hide digital data that must be shared with other authorised people or investigators. Rogue employees often try to hide sensitive information without authorisation. They may have carried out or plan to carry out some nefarious acts. Internal investigators may want to know about such plans. Police as well as investigators from different government departments use this type of investigation frequently to unearth evidence and establish connection between the crime and the suspect. It also helps prove innocence of a suspect or victim.


Why Conduct Such a Thorough Investigation?

People with criminal intent try to hide their digital data tracks. They try to delete information, data and images. Most such people fail to realise that deleted data can be recovered from memory devices even after completing the deletion process. There are software programs that run deep scans and can unearth even those data that were deleted, removed, erased, copied or moved. It has its limitation but some types of data can be recovered. Forensic investigation can reveal information related to the use processes and sessions. It can reveal date and time when the device was accessed and how long it was used during each session. Reports and results of such investigations are admissible as evidence in the court of law.


Digital data forensics has become crucial in internal investigations conducted by companies. Employees who try to defraud their company can be indicted with the evidence collected from their computer. Data obtained this way is now used in criminal cases and civil matters. Investigators can find when the culprit attempted to delete or cover up the evidence. Such actions by a suspect indicate an intention to harm the company, state or person. Forensic level data investigation helps indict such individuals for their crimes.
