Digital forensic is part of forensic science that implicitly covers crime related to computer and other digital devices. It‟s being for a while that academic studies are interested in digital forensics. The researchers aim to find out a discipline based on scientific structures that defines a model reflecting their observations. This paper suggests a model to improve the whole investigation process and obtaining an accurate and complete evidence and adopts securing the digital evidence by cryptography algorithms presenting a reliable evidence in a court of law. This paper presents the main and basic concepts of the frameworks and models used in digital forensics investigation.

With the advancement and growing science of technology and the internet, the threats to data and digital devices have been increasing due to hackers and data invigilators. So the branch of DIGITAL FORENSIC has been set up for the investigation of the cybercrimes committed through the means of the internet, network, digital devices, etc. There are millions of internet users worldwide who are targeted by these hackers, and they lose their data to these data thieves unknowingly. This data can be misused by cybercriminals for various purposes. This branch of forensic science tracks and investigates these cyber criminals and finds the appropriate evidence against them. This paper surveys the work of this branch gives you a brief explanation about the various sub-branches, job opportunities available, and several tools used in this investigation process.

Digital Forensic

The study and practice of forensic science comprises many distinct areas that range from behavioral to biological to physical and to digital matters, and in each area forensic science is utilized to obtain evidence that will be admissible within the legal framework. This article focuses on inconsistencies within the accepted methodology of digital forensics when comparing the current best practices of mobile digital devices and traditional computer devices. Here the authors raise the awareness of this disconnect in methodology, and they posit that some specific tasks within the traditional best practices of digital forensic science are artifacts of ritual rather than based on scientific requirements.

Investigation Process

The extensive use of digital devices by individuals generates a significant amount of private data which creates challenges for investigation agencies to protect suspects' privacy. Existing digital forensics models illustrate the steps and actions to be followed during an investigation, but most of them are inadequate to investigate a crime with all the processes in an integrated manner and do not protect suspect's privacy. In this paper, we propose the development of a privacy-preserving digital forensics (P2DF) framework, which facilitates investigation through maintaining confidentiality of the suspects through various privacy standards and policies. It includes an access control mechanism which allows only authorized investigators to access private data and identified digital evidences. It is also equipped with a digital evidence preservation mechanism which could be helpful for the court of law to ensure the authenticity, confidentiality, and reliability of the evidences, and to verify whether privacy of the suspect was preserved during the investigation process.

Digital crimes are taking place over the entire world. For any digital crime which commit at any part of world, computer or any electronic devices are used. The devices which are used to commit the crime are useful evidences which must be identified and protected for further use. The crimes involving electronic devices are called as cyber-crime. To investigate such crimes, a scientific procedures needs to be followed. The data collection, analysis, preservation and presentation of digital evidence is must in order investigate the cybercrime. This paper highlights the practices that are used worldwide in the investigation process of cyber-crime. Keywords: Digital Forensics, Analysis, Investigation, models of investigation.

AbstractThe field of digital forensics has grown exponentially to include a variety of digital devices on which digitally stored information can be processed and used for different types of crimes. As a result, as this growth continues, new challenges for those conducting digital forensic examinations emerge. Digital forensics has become mainstream and grown in importance in situations where digital devices used in the commission of a crime need examining. This article reviews existing literature and highlights the challenges while exploring the lifecycle of a mobile phone examination and how the disclosure and admissibility of digital evidence develops.

Principles And Standards

The discipline of digital forensics requires a combination of skills, qualifications and knowledge in the area of forensic investigation, legal aspects and information technology. The uniqueness of digital evidence makes the adoption of traditional legal approaches problematic. Information technology terminology is currently used interchangeably without any regard to being unambiguous and consistent in relation to legal texts. Many of the information technology terms or concepts have not yet achieved legal recognition. The recognition and standardisation of terminology within a legal context are of the utmost importance to ensure that miscommunication does not occur. To provide clarity or guidance on some of the terms and concepts applicable to digital forensics and for the search and seizure of digital evidence, some of the concepts and terms are reviewed and discussed, using the Criminal Procedure Act 51 of 1977 as a point of departure. Digital evidence is often collected incorrectly and analysed ineffectively or simply overlooked due to the complexities that digital evidence poses to forensic investigators. As with any forensic science, specific regulations, guidelines, principles or procedures should be followed to meet the objectives of investigations and to ensure the accuracy and acceptance of findings. These regulations, guidelines, principles or procedures are discussed within the context of digital forensics: what processes should be followed and how these processes ensure the acceptability of digital evidence. These processes include international principles and standards such as those of the Association of Chiefs of Police Officers and the International Organisation of Standardisation. A summary is also provided of the most influential or best-recognised international (IOS) standards on digital forensics. It is concluded that the originality, reliability, integrity and admissibility of digital evidence should be maintained as follows: Data should not be changed or altered. Original evidence should not be directly examined. Forensically sound duplicates should be created. Digital forensic analyses should be performed by competent persons. Digital forensic analyses should adhere to relevant local legal requirements. Audit trails should exist consisting of all required documents and actions. The chain of custody should be protected. Processes and procedures should be proper, while recognised and accepted by the industry. If the ACPO (1997) principles and ISO/IEC 27043 and 27037 Standards are followed as a forensic framework, then digital forensic investigators should follow these standards as a legal framework.

Unique Association

Investigation of every crime scene with digital evidence is predominantly required in identifying almost all atomic files behind the scenes that have been intentionally scrubbed out. Apart from the data generated across digital devices and the use of diverse technology that slows down the traditional digital forensic investigation strategies. Dynamically scrutinizing the concealed or sparse metadata matches from the less frequent archives of evidence spread across heterogeneous sources and finding their association with other artifacts across the collection is still a horrendous task for the investigators. The effort of this article via unique pockets (UP), unique groups (UG), and unique association (UA) model is to address the exclusive challenges mixed up in identifying incoherent associations that are buried well within the meager metadata field-value pairs. Both the existing similarity models and proposed unique mapping models are verified by the unique metadata association model.
