Digital Forensic Investigations (DFI) using Internet of Things (IoT)

Digital Forensic Investigations is explained as are sponse to an event that has already occurred in relation to information which is highly classified or is of prime importance to a criminal incident. The case is considered when the suspect's electronic gadgets are seized. The related investigation proceeds to search for the traces in the image of the actual evidence. The traces of deleted, overwritten and archived files could also be found in forensic software's like EnCase, FTK etc. To ensure the evidence is well represented in the court of law, the examination is conducted in a sequential and legal manner. Softwares used in forensic investigations e.g. Encase, FTK etc. gives the entire details of the case, date and time, investigations involved and information on the computer itself. The process mainly lays emphasis on four main stages: i) Investigation Preparation, ii)Evidence Acquisition, iii) Analysis of Evidence and iv) Result Dissemination. The most essential component in DFI is the proper acquisition of the evidence. The DFI is preferably never performed on the actual exhibits that are seized from the crime scene. Hence, evidence acquisition holds huge importance. Although various forensic methods have been proved for their reliability and credibility in the criminal justice system, their main problem lies in the necessity of highly qualified investigators. The investigators should be vigilant right from the preparation required for investigating a crime scene till the dissemination of the result. The paper mainly lays emphasis on the most influential methods involved in the DFI and the effective results obtained.
