An Anti-Money Laundering Methodology: Financial Regulations, Information Security and Digital Forensics Working Together.

Abstract: Analysing large amounts of financial information within databases can be hardly accomplished when dealing with money laundering. The main reason is the lack of digital forensics and proper database analysis procedures within the anti-money laundering strategies of financial institutions. Also, analysing single or grouped financial events related to money laundering is difficult when the Know-Your-Customer Policies in these institutions are not enforced, or even used as evidentiary instruments to gather digital evidence and track suspicious customers through the whole investigation life cycle. Even though the relevant data sources to get information from can be identified and used to create Suspicious Activity Reports, they need to be protected from money laundering events, and by these means, prevent their confiscation. Hence, in this article, we propose a methodology for combining digital forensics and database analysis in order to enhance money laundering detection. Additionally, in order to tackle the lack of synergy between the KYC policies and Information Security requirements, we enhance our previous model by analysing the FATF recommendations, the Basel Frameworks along with the BS ISO/IEC 27001, 27002 and 27037 standards in order to incorporate some of their best-practices into a methodology for money laundering detection model to deliver a set of requirements and activities for customer verification and financial evidence extraction before, during, and after a suspicious activity takes place.

The Information-Seeking Behavior of Digital Evidence Examiners

Abstract: The current research sought to gain in-depth insights into the information-seeking behavior of Turkish National Police digital evidence examiners (DEEs); to explore the information sources that DEEs use and the factors affecting their decisions about source selection. Factors that affect information source selection and use by DEEs are: accreditation, workload, type of information, time, cost, availability, reliability/scientific importance, up-to-date data, prior experience with the source, relevance, interactivity and importance. The Internet was the information source most commonly used by participants during the examination stage; other sources included forums, experts, colleagues, forensic tools/kits and books. During the analysis stage, the most frequently mentioned information source was the investigation file, containing information about the elements of the crime; other sources included: personal experience, experts, detectives, the Internet, clients, professional training, the prosecutor, evidence submission forms, in-lab manuals, forums and colleagues. During the report-writing stage, most DEEs used in-lab manuals and report templates as information sources, but previously written reports, editing software, and colleagues were also used to obtain information about the format, style and language of reports as legal documents.

A log file digital forensic model

Abstract: This paper describes a digital forensic model for investigating computer networks, focusing specifically on network log mining. A thorough examination of log files is needed to reveal the hidden actions of criminals in computer networks. The proposed model specifies the steps that forensic investigators can follow with regard to the extraction and examination of digital evidence from log files for use in legal proceedings.

Digital Forensics: Challenges and Future Research Directions

Abstract: Information and communications technologies (ICT) are fundamental to modern society and open the door to increased productivity, faster communication capabilities, and immeasurable convenience. The increased dependence on ICT and the pervasive interconnectivity of our ICT infrastructure also change the way criminals conduct their activities. There is a need for policing to adapt enforcement and investigation strategies in order to account for these changes. This chapter looks at challenges faced by law enforcement agencies in examining digital evidence for modern communication technologies. Three potential research questions are identified in the areas of physical memory forensics, forensic investigation in the cloud environment, and alternatively non prosecution-based approaches to low-end/less serious high volume data cyber criminal cases.

The use of UAVs and photogrammetry for the documentation of cultural heritage monuments: the case study of the churches in Cyprus

Abstract: Innovative technologies provide an accurate, simple and cost-effective method of documenting cultural heritage sites and generating digital 3D models using novel techniques and innovative methods. These digital 3D models can then be saved in a central database that can be accessed by end users. The project “Digital unblocking of holy islands” proposes digital service requires the creation of digital infrastructure and its enrichment with culturally digital evidence and data, in order to serve as an information hub for the management and promotion of ecclesiastical cultural heritage. The internal and external digitization of ecclesiastical monuments will be carried out using several methods, including images from Unmanned Aerial Vehicles and photogrammetry. Hundreds of images from the monument will be taken using a UAV with an attached high-resolution camera. The images will then be processed through photogrammetry to provide a digital model of the church. The use of digital technology to document cultural heritage within a structure, creates a dynamic database and valuable resource to better understand the cultural heritage monument, as end-users will be able to access the information from the digital platform at any time. This research is supported by the project entitled: “Navigators of Cultural Heritage Digitization of Churches of Cyprus and Crete” referred as “Digital unblocking of holy islands” and is co-funded by the European Regional Development Fund (ERDF)and by national funds of Greece and Cyprus, under the Cooperation Programme “INTERREG V-A GreeceCyprus 2014-2020”
