Today, more and more information is being produced in a digital form. In addition to this so-called born-digital content, material that was produced to exist in an analogue form is now being digitised both for preservation and for easier access. This digital information comes in an ever greater variety of formats, many of which are relatively short-lived. Newer versions of the same software are...

With digital recording devices readily available to most people, events are documented and shared on-line in real time by the “person on the street.” The ease of creation and dissemination belies what archivists know will be the long-term challenges of organizing and preserving collections of born-digital information. While other processes require little modification, the inherent fragility of ...

Computer forensics has the main objective to find digital evidences of crimes. One of the most researched digital crimes is the sexual abuse of children, including the production, sharing and possession of child pornographic files. Aiming to quickly detect files of child pornography at crime scenes, the NuDetective Forensic Tool was previously developed and it uses techniques like nudity detect...

Advanced Audio Coding (AAC), a standardized lossy compression scheme for digital audio, which was designed to be the successor of the MP3 format, generally achieves better sound quality than MP3 at similar bit rates. While AAC is also the default or standard audio format for many devices and AAC audio files may be presented as important digital evidences, the authentication of the audio files i...

MPEG Layer-3, otherwise known as MP3, has generated a phenomenal interest among Internet users, or at least among those who want to download highly-compressed digital audio files at near-CD quality.

When web archive data are not being actively used, it is usually beneficial to ingest them into a digital library for curation. However, it becomes a challenge when the volume of the data grows beyond the size of a typical repository. We propose to augment the digital library with external mass storage. More specifically, we developed a Java library to bridge the Fedora Commons repository with ...

Background & Aims: Conventional radiography is used for the diagnosis of problems such as dental caries and failure in root canal therapy. The diagnosis accuracy of conventional radiography is acceptable in the evaluation of anatomical and pathological structures. However, it seems that by using digital radiography we can obtain more information in this field. The aim of this study is to compar...

Unlike most traditional media, the Internet is both digital and interactive. Here we do not simply refer to interactions between consumers and a Web site or e-mail, but also between the marketer and the firm’s Web site or e-mail. Furthermore, the digital nature of the Internet records every interaction. These two characteristics — interactivity and digitization — facilitate research possibiliti...

iPhone logical backup files can provide forensic examiners with almost the entire contents of its host phone up until the point that the backup took place. This paper serves to provide an overview of the information attainable via the analysis of an iPhone backup, making references to the applicability of such analysis in the digital forensics field. The paper introduces the backup directories ...
