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


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

MPLS VPN Security


MPLS VPN Security
Cisco Press | June 18, 2005 | ISBN: 1587051834 | 312 pages | CHM | 5.2 MB

A practical guide to hardening MPLS networks

* Define "zones of trust" for your MPLS VPN environment
* Understand fundamental security principles and how MPLS VPNs work
* Build an MPLS VPN threat model that defines attack points, such as VPN separation, VPN spoofing, DoS against the network’s backbone, misconfigurations, sniffing, and inside attack forms
* Identify VPN security requirements, including robustness against attacks, hiding of the core infrastructure, protection against spoofing, and ATM/Frame Relay security comparisons
* Interpret complex architectures such as extranet access with recommendations of Inter-AS, carrier-supporting carriers, Layer 2 security considerations, and multiple provider trust model issues
* Operate and maintain a secure MPLS core with industry best practices
* Integrate IPsec into your MPLS VPN for extra security in encryption and data origin verification
* Build VPNs by interconnecting Layer 2 networks with new available architectures such as virtual private wire service (VPWS) and virtual private LAN service (VPLS)
* Protect your core network from attack by considering Operations, Administration, and Management (OAM) and MPLS backbone security incidents

Multiprotocol Label Switching (MPLS) is becoming a widely deployed technology, specifically for providing virtual private network (VPN) services. Security is a major concern for companies migrating to MPLS VPNs from existing VPN technologies such as ATM. Organizations deploying MPLS VPNs need security best practices for protecting their networks, specifically for the more complex deployment models such as inter-provider networks and Internet provisioning on the network.

MPLS VPN Security is the first book to address the security features of MPLS VPN networks and to show you how to harden and securely operate an MPLS network. Divided into four parts, the book begins with an overview of security and VPN technology. A chapter on threats and attack points provides a foundation for the discussion in later chapters. Part II addresses overall security from various perspectives, including architectural, design, and operation components. Part III provides practical guidelines for implementing MPLS VPN security. Part IV presents real-world case studies that encompass details from all the previous chapters to provide examples of overall secure solutions.

Drawing upon the authors’ considerable experience in attack mitigation and infrastructure security, MPLS VPN Security is your practical guide to understanding how to effectively secure communications in an MPLS environment.

Special Ops: Internal Network Security Guide is the solution for the impossible 24-hour IT work day. By now, most companies have hardened their perimeters and locked out the "bad guys," but what has been done on the inside? This book attacks the problem of the soft, chewy center in internal networks. We use a two-pronged approach-Tactical and Strategic-to give readers a complete guide to internal penetration testing. Content includes the newest vulnerabilities and exploits, assessment methodologies, host review guides, secure baselines and case studies to bring it all together. We have scoured the Internet and assembled some of the best to function as Technical Specialists and Strategic Specialists. This creates a diversified project removing restrictive corporate boundaries. The unique style of this book will allow it to cover an incredibly broad range of topics in unparalleled detail. Chapters within the book will be written using the same concepts behind software development. Chapters will be treated like functions within programming code, allowing the authors to call on each other's data. These functions will supplement the methodology when specific technologies are examined thus reducing the common redundancies found in other security books.

Internet Firewalls and Network Security

Karanjit S. Siyan, Internet Firewalls and Network Security
New Riders Publishing ISBN: 1562056328 1996 PDF 720 pages 10.11 MB
Internet Firewalls and Network Security succeeds precisely because of its restricted focus: half of this book is devoted to firewalls and packet filters. After a comprehensive introduction to the architecture and theory of firewalls, the guide documents several commercial and noncommercial packages, including a shareware product included on the bundled CD-ROM. One of the book's highlights is a fine chapter on defining a network policy. Coauthor Chris Hare is a contributor to SysAdmin magazine, and it shows. This section feels like it was written for real-world network administrators, whether beginning or experienced. There are some weaker points, including an introduction to TCP/IP and Unix basics with too many details for the beginner and too few for the expert. But these flaws are more than offset by the depth of information you'll find on the book's core subjects.
