Visual Cryptography and Secret Image Sharing (Digital Imaging and Computer Vision)

Published on 8:16 AM Category: Ebooks, Network Security

Visual Cryptography and Secret Image Sharing (Digital Imaging and Computer Vision) by Stelvio Cimato, Ching-Nung Yang
CRC Press | English | 2011 | ISBN: 143983721X | 545 pages | PDF | 9 MB

With rapid progress in Internet and digital imaging technology, there are more and more ways to easily create, publish, and distribute images. Considered the first book to focus on the relationship between digital imaging and privacy protection, Visual Cryptography and Secret Image Sharing is a complete introduction to novel security methods and sharing-control mechanisms used to protect against unauthorized data access and secure dissemination of sensitive information.

Image data protection and image-based authentication techniques offer efficient solutions for controlling how private data and images are made available only to select people. Essential to the design of systems used to manage images that contain sensitive data—such as medical records, financial transactions, and electronic voting systems—the methods presented in this book are useful to counter traditional encryption techniques, which do not scale well and are less efficient when applied directly to image files.

An exploration of the most prominent topics in digital imaging security, this book discusses:

Potential for sharing multiple secrets

Visual cryptography schemes—based either on the probabilistic reconstruction of the secret image, or on different logical operations for combining shared images

Inclusion of pictures in the distributed shares

Contrast enhancement techniques

Furthermore, throughout the book, extensive hands-on examples provide you with practical experience in establishing security with firewalls. Examples include, but are not limited to: Installing and configuring Check Point FireWall-1; scanning to validate configuration using ISS Internet Scanner; configuring the firewall to support simple and complex Web services; setting up a packet filtering router; enhancing firewall configurations to support split-DNS; authenticating remote users; and protecting browsers and servers with a proxy-based firewall.

· Install and configure proxy-based and stateful-filtering firewalls
· Protect internal IP addresses with NAT and deploy a secure DNS architecture
· Develop an Internet/intranet security policy to protect your organization's systems and data
· Reduce your susceptibility to an attack by deploying firewalls, data encryption and decryption and other countermeasures

Voice over IP Security

Published on 11:20 AM Category: Certification, Ebooks, Network Security

Patrick Park, "Voice over IP Security"
Cisco Press | 2008 | ISBN: 1587054698, 1587058200 | 384 pages | PDF | 3 MB

VoIP security issues are becoming increasingly serious because voice networks and services cannot be protected from recent intelligent attacks and fraud by traditional systems such as firewalls and NAT alone. After analyzing threats and recent patterns of attacks and fraud, consideration needs to be given to the redesign of secure VoIP architectures with advanced protocols and intelligent products, such as Session Border Controller (SBC). Another type of security issue is how to implement lawful interception within complicated service architectures according to government requirements.

Voice over IP Security focuses on the analysis of current and future threats, the evaluation of security products, the methodologies of protection, and best practices for architecture design and service deployment. This book not only covers technology concepts and issues, but also provides detailed design solutions featuring current products and protocols so that you can deploy a secure VoIP service in the real world with confidence.

Voice over IP Security gives you everything you need to understand the latest security threats and design solutions to protect your VoIP network from fraud and security incidents.

Patrick Park has been working on product design, network architecture design, testing, and consulting for more than 10 years. Currently Patrick works for Cisco® as a VoIP test engineer focusing on security and interoperability testing of rich media collaboration gateways. Before Patrick joined Cisco, he worked for Covad Communications as a VoIP security engineer focusing on the design and deployment of secure network architectures and lawful interception (CALEA). Patrick graduated from the Pusan National University in South Korea, where he majored in computer engineering.
