Two families comprising six simple schemata, which reproduce with high accuracy the outputs of Bayesian belief networks as used in actual digital forensic investigations, are described, analyzed, and evaluated numerically. Their application as a forensic triage measure to help in deciding whether a full digital forensic investigation is warranted is critically discussed. The concept of a digita...

Representatives from a variety of distributed digital preservation initiatives will serve as panel members and discuss the technical adaptability, economics, and functionally compelling benefits of using cooperative distributed digital preservation networks to preserve the vast array of at-risk digital content produced by our societies and their institutions.

Over the past decade, wireless mobile communication technology based on the IEEE 802.11 Wireless Local Area Networks (WLANs) has been adopted worldwide on a massive scale. However, as the number of wireless users has soared, so has the possibility of cybercrime. WLAN digital forensics is seen as not only a response to cybercrime in wireless networks, but also a means to stem the increase of cyb...

In the center of the current digital revolution is the digital convergence phenomenon. The ability to convert various types of analog data to digital form has made it possible for such data as voice, music, photographic images and video to be stored in computers, processed using computers, transmitted via digital communications networks, and presented on both digital and analog devices. Digital...

This chapter deals with a stream cipher method for encrypting images. As digital devices such as scanners and digital cameras become more and more available and mass storage media for digital data become more affordable, the use of digital images in practical applications are becoming more widespread. The wired and wireless IP networks are vulnerable to eavesdropping making essential the data t...

TOOLS & TECHNOLOGIES USED A start-up company that was looking to provide easy digital content access to millions of consumers in India through a network of Digital Vending Machines (DVMs) or kiosks. Their vision was to become a consumer brand in the digital content landscape by delivering all forms of digital content and services at a low cost, through multiple retail networks such as music caf...

This paper develops a design of two-dimensional (2D) digital filter with monotonic amplitude-frequency responses using Darlington-type gyrator networks by the application of Generalized Bilinear Transformation (GBT). The proposed design provides the stable monotonic amplitude-frequency responses and the desired cutoff frequency of the 2D digital filters. This 2D recursive digital filter design ...

The digital exhaust left by flows of physical and digital commodities provides a rich measure of the nature, strength and significance of relationships between countries in the global network. With this work, we examine how these traces and the network structure can reveal the socioeconomic profile of different countries. We take into account multiple international networks of physical and digi...

Transportation planning models are typically used to estimate future traffic patterns, peak period traffic, travel time, and various environmental or other related traffic flow characteristics. Unfortunately, traffic safety is seldom, if ever, explicitly considered proactively during the transportation planning process. This omission is attributed to various factors, including the lack of avail...
