Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year. 相似文献

Whilst the field of digital forensics is now well established, its research community can be considered relatively emerging in comparison to the associated areas of traditional forensic and computer sciences. As a result, this comment article takes a quick look at the demographics of digital forensics research over the last 20 years, with metadata from 6589 articles being extracted and analysed from Scopus in order to provide a brief insight into this field’s research activity. 相似文献

在实行诉讼对抗制的国家,人们可以通过以下三种方法使信息技术证据成为保护企业利益的一种工具:(1)起诉,包括刑事诉讼;(2)法庭辩护;(3)为规则制定者和企业作出重要决策提供依据。然而,对于什么样的信息技术证据具有可采信性,人们仍有质疑。计算机法学正是研究如何确定、保存、分析及如何提交数字证据的一门新兴的学科。尽管传统上计算机法学被认为是一门滞后的学科,但是澳大利亚《信息技术证据管理指引》还是前瞻性地规定了能使电子证据效力最大化的系统生存周期的一些重要原则。 相似文献

The big data era has a high impact on forensic data analysis. Work is done in speeding up the processing of large amounts of data and enriching this processing with new techniques. Doing forensics calls for specific design considerations, since the processed data is incredibly sensitive. In this paper we explore the impact of forensic drivers and major design principles like security, privacy and transparency on the design and implementation of a centralized digital forensics service. 相似文献

目的研究NTFS存储设备的3种数据恢复方式,测试、比较不同方式的恢复效果,促进电子物证检验工作。方法本文针对同一NTFS存储设备,分别使自行设计的NTFS日志检验软件测试基于NTFS日志文件的恢复方式,使用Final Data的快速扫描功能测试基于MFT记录的恢复方式,使用Final Data的完整扫描功能测试基于文件头部存储特征值的恢复方式,比较3种方式的恢复效果,分析各自的恢复原理。结果基于NTFS日志和MFT记录的方式恢复出的信息较全,用时较短,但不适合恢复较长时间之前删除的文件。基于文件头部存储特征值的方式可恢复较长时间前删除的文件,但用时长,不能恢复文件名、创建时间等信息,也不能有效恢复离散存储的文件。结论结合实际情况、综合运用3种方式可有效恢复数据。 相似文献

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures. 相似文献

Do online and offline voters differ in terms of policy preferences? The growth of Internet voting in recent years has opened up new channels of participation. Whether or not political outcomes change as a consequence of new modes of voting is an open question. Here we analyze all the votes cast both offline (n = 5.7 million) and online (n = 1.3 million) and compare the actual vote choices in a public policy referendum, the world's largest participatory budgeting process, in Rio Grande do Sul in June 2014. In addition to examining aggregate outcomes, we also conducted two surveys to better understand the demographic profiles of who chooses to vote online and offline. We find that policy preferences of online and offline voters are no different, even though our data suggest important demographic differences between offline and online voters. 相似文献

Digital citizenship is becoming increasingly normalized within advanced democratic states. As society and governmental institutions become reliant on digital technologies, citizens are expected to be and act digitally. This article examines the governance of digital citizens through a case study of digitalization efforts in Denmark. Drawing on multiple forms of data, the article showcases how digital citizens are governed through a combination of discursive, legal and institutional means. The article highlights the political, but also institutional work that goes into making citizens digital. Providing this case study, the article contributes to current critical perspectives on the digital citizen as a new political figure. It adds new insights into digital citizenship by connecting this figure to wider processes of neoliberalization and state restructuring, pushing for a more pronounced focus on governmental practices. 相似文献
