浅谈数字图像真实性的检验鉴定

随着IT技术的迅速发展,数字图像的采集越来越方便,但通过数码设备形成的数字周像非常容易被篡改。当前国内外均存在照片伪造现象,因案件性质不同,影响的范围也有所差异,但共同的目的都是为了私欲而混淆是非。这就要求我们必须不断提高检验鉴定的水平,还原事实真相。     

Web Content Management Systems: An Analysis of Forensic Investigatory Challenges

With an increase in the creation and maintenance of personal websites, web content management systems are now frequently utilized. Such systems offer a low cost and simple solution for those seeking to develop an online presence, and subsequently, a platform from which reported defamatory content, abuse, and copyright infringement has been witnessed. This article provides an introductory forensic analysis of the three current most popular web content management systems available, WordPress, Drupal, and Joomla! Test platforms have been created, and their site structures have been examined to provide guidance for forensic practitioners facing investigations of this type. Result's document available metadata for establishing site ownership, user interactions, and stored content following analysis of artifacts including Wordpress's wp_users, and wp_comments tables, Drupal's “watchdog” records, and Joomla!'s _users, and _content tables. Finally, investigatory limitations documenting the difficulties of investigating WCMS usage are noted, and analysis recommendations are offered.

Usability and Digital Inclusion: Standards and Guidelines

This article aims at discussing e-government website usability in relation to concerns about digital inclusion. E-government web design should consider all aspects of usability, including those that make it more accessible to all. Traditional concerns of social exclusion are being superseded by fears that lack of digital competence and information literacy may result in dangerous digital exclusion. Usability is considered as a way to address this exclusion and should therefore incorporate inclusion and accessibility guidelines. This article makes an explicit link between usability guidelines and digital inclusion and reports on a survey of local government web presence in Portugal.     

COOPERATIVES FOR THE PERFORMING ARTS: A PROSPECTUS

The author describes research that addresses the problem of organizational change associated with the use of new information and communication technologies. The author focuses on the change processes associated with the use of the World Wide Web by cultural heritage organizations: archives, galleries, libraries, and museums. This research note outlines the research problem and the theoretical perspectives and research methodologies to be used in the research.     

Digital Technology and Cultural Heritage Sites in the City of Tshwane

This article examines the feasibility and sustainability of digital technology to promote cultural heritage sites in the City of Tshwane (CoT), South Africa. Post-Apartheid development imperatives compel the CoT to construct new cultural sites. Over time, the number of visitors to the places declined. The CoT introduced digital technology to collect and repackage information on some of the cultural edifices to add value to them. However, the absence of heritage/digital technology impact analysis and cultural policy in the CoT could compromise the program. The article recommends further introduction of important facilities and services in the sites to increase public interest.     

The Intellectual and Cultural Dimensions of International Relations: Present Ironies and Future Possibilities

Reported is a study that focused on the Millennial Generation and potential differences in viewing an exhibition in person versus online. The exhibition featured the artwork of Paul-Henri Bourguignon, whose extensive body of work includes a variety of paintings and drawings that employ a wide range of styles. Some viewers traveled to the physical space of a museum gallery, while others viewed reproductions of the same works on the Internet. Informants engaged in reflexive self-interviews using Dervin's Sense-Making Methodology. The authors compare viewers’ responses to works experienced in person versus online and discuss implications.     

Digital Network Repertoires and Organizational Hybridity

This article summarizes a study of 37 televised debates on political issues in Denmark, conducted live before representative audiences, with polls on the issues before and after each debate. These debates are of interest to research because they were authentic, and they supply data indicating persuasive effects. Various rhetorical features were observed and related to debaters success in attracting votes. In a qualitative interpretation of the observations, we suggest that debates such as these are likely to be won by debaters whose argumentation is fair and thoughtful. Audiences may respond differently depending on whether they are voters or merely viewers. The debate format may enhance such a response, for the benefit of the democratic process.     

A Novel Forged Image Detection Method Using the Characteristics of Interpolation

Development of digital image‐editing programs has enabled us to be widely exposed to forged digital images surrounding us. Such forged images have been dispersed through the Internet, newspaper articles, and magazines, and in particular, the information contained in these unverified images happened to be regarded as true. As a result, the forged images provided wrong information for individuals and society, thus sometimes creating social issues. In order to solve such problems, this study was aimed to suggest the methods of identifying the veracity of forged images. In this way, it suggested re‐interpolation algorithm. Namely, the study re‐interpolated in identical arbitrary values both the interpolated and un‐interpolated regions based on the interpolation used a lot in forged, confirmed discrete fourier transform (DFT) characteristics of these two regions, and embodied a detection map for the final forged images, using the subtraction value between two regions in DFT characteristics.
