In order, to create the activity of the work businesses easy, use of technology is important. Crime investigation analysis is a section records in data mining plays a crucial role in terms of predicting and learning the criminals. In our paper, we've got planned an incorporated version for physical crime as well as cybercrime analysis. Our approach uses data mining techniques for crime detection and criminal identity for physical crimes and digitized forensic tools (DFT) for evaluating cybercrimes. The presented tool named as Comparative Digital Forensic Process tool (CDFPT) is entirely based on digital forensic model and its stages named as Comparative Digital Forensic Process Model (CDFPM). The primary step includes accepting the case details, categorizing the crime case as physical crime or cybercrime and sooner or later storing the data in particular databases. For physical crime analysis we've used k- means approach cluster set of rules to make crime clusters. -

Forensic Attribution Challenges During Forensic Examinations Of Databases. Master's disser- tation, University of Pretoria, Department of Computer Science, Pretoria, South Africa, September 2018. Electronic, hyperlinked versions of this dissertation are available online, as Adobe PDF files, at: https://repository.up.ac.za/ Forensic Attribution Challenges During Forensic Examinations Of Databases by Werner Karl Hauger E-mail: [email protected] Abstract An aspect of database forensics that has not yet received much attention in the aca- demic research community is the attribution of actions performed in a database. When forensic attribution is performed for actions executed in computer systems, it is nec- essary to avoid incorrectly attributing actions to processes or actors. This is because the outcome of forensic attribution may be used to determine civil or criminal liabil- ity. Therefore, correctness is extremely important when attributing actions in computer systems, also when performing forensic attribution in databases. Any circumstances that can compromise the correctness of the attribution results need to be identified and addressed. This dissertation explores possible challenges when performing forensic attribution in databases. What can prevent the correct attribution of actions performed in a database? The first identified challenge is the database trigger, which has not yet been studied in the context of forensic examinations. Therefore, the dissertation investigates the impact of database triggers on forensic examinations by examining two sub questions. -
Current and Future Trends in Mobile Device Forensics: a Survey
Current and Future Trends in Mobile Device Forensics: A Survey KONSTANTIA BARMPATSALOU, TIAGO CRUZ, EDMUNDO MONTEIRO, and PAULO SIMOES, Centre for Informatics and Systems of the University of Coimbra, Department of Informatics (CISUC/DEI), University of Coimbra, Portugal Contemporary mobile devices are the result of an evolution process, during which computational and networking capabilities have been continuously pushed to keep pace with the constantly growing workload requirements. This has allowed devices such as smartphones, tablets and Personal Digital Assistants (PDAs) to perform increasingly complex tasks, up to the point of efficiently replacing traditional options such as desktop computers and notebooks. However, due to their portability and size, these devices are more prone to theft, to become compromised or to be exploited for attacks and other malicious activity. The need for investigation of the aforementioned incidents resulted in the creation of the Mobile Forensics (MF) discipline. MF, a sub-domain of Digital Forensics (DF), is specialized in extracting and processing evidence from mobile devices in such a way that attacking entities and actions are identified and traced. Beyond its primary research interest on evidence acquisition from mobile devices, MF has recently expanded its scope to encompass the organized and advanced evidence representation and analysis of future malicious entity behavior. Nonetheless, data acquisition still remains its main focus. While the field is under continuous research activity, new concepts such as the involvement of Cloud Computing in the MF ecosystem and the evolution of enterprise mobile solutions – particularly Mobile Device Management (MDM) and Bring Your Own Device (BYOD) – bring new opportunities and issues to the discipline. -

Solving Crimes by Using Forensic Entomology Dr
Solving Crimes by Using Forensic Entomology Dr. Deborah Waller Associate Professor of Biology Old Dominion University The Scenario The following is a hypothetical crime that was solved using insect evidence. Although fictional, this crime represents a compilation of numerous similar forensic entomology cases tried in the legal system where insects helped identify the murderer. The Crime Scene Pamela Martin, a 55 year-old woman, was found deceased in a state of advanced decomposition on March 30th. The body was discovered by her husband John on a path leading to a mountain cabin owned by the couple. The Martins had driven up to the cabin on March 1st, and John had left Pamela there alone while he completed a job in the northeastern region of the state. The Victim Pamela Martin was a former school librarian who devoted her retirement years to reading and gardening. She took medication for a heart condition and arthritis and generally led a quiet life. Pamela was married for 30 years to John Martin, a truck driver who was often gone for months at a time on his rounds. They had no children. The Cabin The cabin was isolated with closest neighbors several kilometers away. There was no internet access and cell phone service was out of range. The couple frequently drove up there to do repairs, and John often left Pamela alone while he made his rounds throughout the state.

DB3F & DF-Toolkit
Digital Investigation 29 (2019) S42eS50 Contents lists available at ScienceDirect Digital Investigation journal homepage: www.elsevier.com/locate/diin DFRWS 2019 USA d Proceedings of the Nineteenth Annual DFRWS USA DB3F & DF-Toolkit: The Database Forensic File Format and the Database Forensic Toolkit * James Wagner a, , Alexander Rasin a, Karen Heart a, Rebecca Jacob a, Jonathan Grier b a DePaul University, Chicago, IL, USA b Grier Forensics, USA article info abstract Article history: The majority of sensitive and personal user data is stored in different Database Management Systems (DBMS). For Example, Oracle is frequently used to store corporate data, MySQL serves as the back-end storage for most webstores, and SQLite stores personal data such as SMS messages on a phone or browser bookmarks. Each DBMS manages its own storage (within the operating system), thus databases require their own set of forensic tools. While database carving solutions have been built by multiple research groups, forensic investigators today still lack the tools necessary to analyze DBMS forensic ar- tifacts. The unique nature of database storage and the resulting forensic artifacts require established standards for artifact storage and viewing mechanisms in order for such advanced analysis tools to be developed. In this paper, we present 1) a standard storage format, Database Forensic File Format (DB3F), for database forensic tools output that follows the guidelines established by other (file system) forensic tools, and 2) a view and search toolkit, Database Forensic Toolkit (DF-Toolkit), that enables the analysis of data stored in our database forensic format. Using our prototype implementation, we demonstrate that our toolkit follows the state-of-the-art design used by current forensic tools and offers easy-to-interpret database artifact search capabilities.
