In the last few decades, the use of the Internet has grown tremendously, and the use of online communications has grown even more. The lack of security in private messages between individuals, however, allows hackers to collect loads of sensitive information. Modern security measures are required to prevent this attack on the world's communication technologies. Advanced Digital Image Steganography Using LSB, PVD, and EMD: Emerging Research and Opportunities provides evolving research exploring the theoretical and practical aspects of data encryption techniques and applications within computer science. The book provides introductory knowledge on steganography and its importance, detailed analysis of how RS and PDH are performed, discussion on pixel value differencing principles, and hybrid approaches using substitution, PVD, and EMD principles. It is ideally designed for researchers and graduate and under graduate students seeking current research on the security of data during transit.

Businesses in today's world are adopting technology-enabled operating models that aim to improve growth, revenue, and identify emerging markets. However, most of these businesses are not suited to defend themselves from the cyber risks that come with these data-driven practices. To further prevent these threats, they need to have a complete understanding of modern network security solutions and the ability to manage, address, and respond to security breaches. The Handbook of Research on Intrusion Detection Systems provides emerging research exploring the theoretical and practical aspects of prominent and effective techniques used to detect and contain breaches within the fields of data science and cybersecurity. Featuring coverage on a broad range of topics such as botnet detection, cryptography, and access control models, this book is ideally designed for security analysts, scientists, researchers, programmers, developers, IT professionals, scholars, students, administrators, and faculty members seeking research on current advancements in network security technology.

The rise of network-based, automated services in the past decade has definitely changed the way businesses operate, but not always for the better. Offering services, conducting transactions and moving data on the Web opens new opportunities, but many CTOs and CIOs are more concerned with the risks. Like the rulers of medieval cities, they've adopted a siege mentality, building walls to keep the bad guys out. It makes for a secure perimeter, but hampers the flow of commerce.

Fortunately, some corporations are beginning to rethink how they provide security, so that interactions with customers, employees, partners, and suppliers will be richer and more flexible. "Digital Identity" explains how to go about it. This book details an important concept known as "identity management architecture" (IMA): a method to provide ample protection while giving good guys access to vital information and systems. In today's service-oriented economy, digital identity is everything. IMA is a coherent, enterprise-wide set of standards, policies, certifications and management activities that enable companies like yours to manage digital identity effectively--not just as a security check, but as a way to extend services and pinpoint the needs of customers.

Author Phil Windley likens IMA to good city planning. Cities define uses and design standards to ensure that buildings and city services are consistent and workable. Within that context, individual buildings--or system architectures--function as part of the overall plan. With Windley's experience as VP of product development for [email protected] and CIO of Governor Michael Leavitt's administration in Utah, he provides a rich, real-world view ofthe concepts, issues, and technologies behind identity management architecture.

How does digital identity increase business opportunity? Windley's favorite example is the ATM machine. With ATMs, banks can now offer around-the-clock service, serve more customers simultaneously, and do it in a variety of new locations. This fascinating book shows CIOs, other IT professionals, product managers, and programmers how security planning can support business goals and opportunities, rather than holding them at bay.

From transportation to healthcare, IoT has been heavily implemented into practically every professional industry, making these systems highly susceptible to security breaches. Because IoT connects not just devices but also people and other entities, every component of an IoT system remains vulnerable to attacks from hackers and other unauthorized units. This clearly portrays the importance of security and privacy in IoT, which should be strong enough to keep the entire platform and stakeholders secure and smooth enough to not disrupt the lucid flow of communication among IoT entities. Applied Approach to Privacy and Security for the Internet of Things is a collection of innovative research on the methods and applied aspects of security in IoT-based systems by discussing core concepts and studying real-life scenarios. While highlighting topics including malware propagation, smart home vulnerabilities, and bio-sensor safety, this book is ideally designed for security analysts, software security engineers, researchers, computer engineers, data scientists, security professionals, practitioners, academicians, and students seeking current research on the various aspects of privacy and security within IoT.
