Recently, digital forensics has become increasingly important as it is used by investigation agencies, corporate, and private sector. To supplement the limitations of evidence capacity and be recognized in court, it is essential to establish an environment that ensures the integrity of the entire process ranging from collecting and analyzing to submitting digital evidence to court. In this study, common elements were extracted by comparing and analyzing ISO/IEC 17025, 27001 standards and Interpol and Council of Europe (CoE) guidelines to derive the necessary components for building a digital forensic laboratory. Subsequently, based on 21 digital forensic experts in the field, Delphi survey and verifications were conducted in three rounds. As a result, 40 components from seven areas were derived. The research results are based on the establishment, operation, management, and authentication of a digital forensics laboratory suitable for the domestic environment, with added credibility through collection of the opinions of 21 experts in the field of digital forensics in Korea. This study can be referred to in establishing digital forensic laboratories in national, public, and private digital forensic organizations as well as for employing as competency measurement criteria in courts to evaluate the reliability of the analysis results. 相似文献

How do market actors in the contemporary economy make decisions when they are uncertain of the value of what is being traded? To answer this question, this paper analyses the changing temporal and spatial orientation of economic valuations in increasingly digitalized economies, in which markets can no longer be understood as locally bound and closed sites of valuation and exchange. Drawing on ethnographic material from the fishing industry, the paper shows how digital tracking technologies link and synchronize auction markets with real-time information on fishing activities. Hence, ‘scopic media’ such as chart plotters and computer screens are not only deployed by skippers to monitor one another, but are also used as valuation devices that recontextualize local knowledge for the purpose of coping with economic uncertainty. As a consequence of this panoptic valuation regime, fishermen control their virtual identities by disciplining harvesting practices according to their buyers’ expectations. 相似文献

Advances in technologies including development of smartphone features have contributed to the growth of mobile applications, including dating apps. However, online dating services can be misused. To support law enforcement investigations, a forensic taxonomy that provides a systematic classification of forensic artifacts from Windows Phone 8 (WP8) dating apps is presented in this study. The taxonomy has three categories, namely: Apps Categories, Artifacts Categories, and Data Partition Categories. This taxonomy is built based on the findings from a case study of 28 mobile dating apps, using mobile forensic tools. The dating app taxonomy can be used to inform future studies of dating and related apps, such as those from Android and iOS platforms. 相似文献

Diversity is a core value of cultural policy, and new global digital conditions for creative industries mean new challenges for diversity at a national level. Internet has become a new infrastructure for services and platforms, and global actors as Google and Amazon are changing the play. This article concerns digitization of books, the collection of the National Library of Norway and cultural policy. The results indicate the National Library's digital collection contributes to diversity in terms of demography, content, dissemination and techno-cultural aspects. For policy makers, libraries and researchers the study demonstrates a national digital service's contribution to expanded diversity. 相似文献

Identification of Mobile Phone and Analysis of Original Version of Videos through a Delay Time Analysis of Sound Signals from Mobile Phone Videos 下载免费PDF全文
This study designs a method of identifying the camera model used to take videos that are distributed through mobile phones and determines the original version of the mobile phone video for use as legal evidence. For this analysis, an experiment was conducted to find the unique characteristics of each mobile phone. The videos recorded by mobile phones were analyzed to establish the delay time of sound signals, and the differences between the delay times of sound signals for different mobile phones were traced by classifying their characteristics. Furthermore, the sound input signals for mobile phone videos used as legal evidence were analyzed to ascertain whether they have the unique characteristics of the original version. The objective of this study was to find a method for validating the use of mobile phone videos as legal evidence using mobile phones through differences in the delay times of sound input signals. 相似文献
