    This book presents the experimental development of an information-powered engine inspired by the famous thought experiment, Maxwell¿s demon, to understand its potential to produce energy for practical purposes. The development of an engine based on Maxwell¿s demon was for a long time inconceivable, but technological advances have led to novel investigations into theoretical and practical applications. The built information engine consists of a micron-sized glass bead trapped in a tightly focused laser beam. It rectifies the bead's Brownian motion by controlling the laser's position and generates a unidirectional motion against gravity without doing any work, thus converting thermal heat into stored gravitational potential energy. A theoretical model based on a spring-mass system describes the engine's dynamics and was then used to find optimum parameters to improve the engine's performance. Experimentally implementing these optimization strategies led to engine output powers comparable to those measured in biological motors. This book also highlights performance improvements made in the presence of measurement noise and presents important guiding principles to design information engines to operate in non-equilibrium environments. By focusing on practical applications, the book overall aims to broaden the scope of information-engine investigations.

    Cryptography has become an integral part of the globe. The need to secure things has become a necessity as the world leaps towards technology enhancements. Modern security systems use cryptography for secure transactions and communications, to secure personal information and other confidential data, to create trust between different servers etc. Weak cryptography may expose the infrastructure to vulnerabilities. This may cause information leakage and brand destruction. Hence, the latest development in technologies should also sternly focus on how cryptography is employed and managed throughout the innovations. With these novelties, it is very safe to transmit sensitive information since they become unreadable and unmodifiable. The plaintext is in a readable format which is then encrypted to get the cipher text. The cipher text is the encrypted data which is in a non-readable format. The cipher text is then decrypted to get the plaintext back which is in the readable format. The major aspects to be included in a crypto module includes the algorithms, the keys, libraries and the certificates that are being used. The use of cryptographic keys is to protect sensitive information. The length of the keys should be maintained as suggested by the NIST (National Institute of Standards and Technology) and private keys must be kept secret to be effective. The use of insecure keys or disclosing the secret keys makes the crypto algorithm obsolete. Crypto algorithms have the basic mathematical foundation to maintain the confidentiality, integrity and authenticity of sensitive information. It is important to choose reliable, standardized and mathematically secure crypto algorithms to prevent data exposure, data tampering, or repudiation. In the present time, cryptography has become a mandatory source for digital business. The organizations and technologies that provide crypto security should follow the techniques suggested by standard groups such as NIST and ISO (International Organization for Standardization). This leads to crypto agility which is the key to keeping pace with the latest cryptographic compliance requirements, standards, and recommendations that sustain and secure digital business.

    The primary means of communication in today's digital world is the internet, whose characteristics are secrecy, privacy, confidentiality, and authentication. Among the most common methods for securely sending and receiving data are steganography and cryptography. Both of these techniques are fundamental components of information security, even though they work differently. Security of critical information and privacy, as well as the security of individual user transactions over open networks has become not only a necessity but also something that has grown more and more significant. The scope of applications of information and multimedia security research has expanded dramatically in recent years. Confidentiality, integrity, and authenticity are the goals of information security. Since not all information is of equal importance and is likely to be attacked by unauthorized parties, security requirements and procedures must be tailored accordingly. It is necessary to follow highly secure procedures and assign different levels of priority to authorized parties for highly secret data, such as in the case of government, military, and banking. However, security is primarily concerned with preventing the unauthorized use of resources in academic and scientific applications. Steganography hides secret data from third parties, while cryptography prevents outsiders from reading the information. As far as highly secret information is concerned, the government, military, and banking sectors require extremely secure procedures, and they assign different levels of priority to authorized parties according to their level of responsibility. Security is primarily concerned with preventing unauthorized access to resources in academic and scientific environments. Steganography is a method that aims to achieve resilience, transparency, and conceal ability. Embedding is a method of enclosing a message with a stego key that is the same for transmitter and receiver. This output gives a stego sound. At their receiver side, the inserted text is recovered from the cover audio using the stego key. Different steganography techniques utilize images, text, and audio, video, and network protocols. In contrast to the Human Auditory System, which is more sensitive to distortions in audio cover files, the Human Visual System is less sensitive to image alteration. As a result of this, it is considered as a source of motivation for researchers to develop new methods of audio steganography. Steganography techniques are primarily concerned with image steganography schemes, rather than audio steganography schemes.

    Cryptography is the science that studies various mathematical aspects of information security used to protect data that is communicated over an insecure channel or stored in an unprotected medium. As Rivest said, it "is about communication in the presence of an adversary" [1]. Though historical records indicate the usage of secret messages around 4000 years ago, cryptography, as we see it today, is just less than 100 years old. The military and governments predominantly used classical cryptography to maintain the confidentiality of the information communicated. With the advent of computers and the internet, cryptography became more and more ubiquitous by being part of a multitude of applications, and now each of us knowingly or unknowingly employs it while using internet banking, e-commerce, smartphones, Internet of Things (IoT), etc. Apart from confidentiality, which is considered the central aspect of information se- curity, modern cryptography focuses on three fundamental services: integrity, authen- tication, and non-repudiation. The set of algorithms used to provide these information security functions is known as cryptosystem. A present-day cryptosystem addresses the following:

    This book takes readers through the sensational history of blockchains and their potential to revolutionize database systems of the future. In order to demystify blockchains, the book capitalizes on decades of research and field testing of existing database and distributed systems and applies these familiar concepts to the novel blockchain system. It then utilizes this framework to explore the essential block platform underpinning blockchains, which is often misunderstood as a specific attribute of cryptocurrencies rather than the core of the decentralized system independent of application. The book explores the nature of these decentralized systems, which have no single owner and build robustness through a multitude of stakeholder contributions. In this way, blockchains can build trust into existing systems and thus present attractive solutions for various domains across both academia and industry. Despite this, high-impact and real-world applications of blockchain have yet to be realized outside of cryptocurrencies like Bitcoin. The book establishes how this new data system, if properly applied, can disrupt the sector in much the same way databases did so many years ago. The book explores the fundamental technical limitations that may be preventing blockchain from realizing this potential and how to overcome or mitigate them. Readers who are completely new to blockchains will find this book to be a comprehensive survey of the state of the art in blockchain technology. Readers with some experience of blockchains, for example through developing cryptocurrencies, will likely find the book's database perspective enlightening. Finally, researchers already working with blockchain will learn to identify existing gaps in the design space and explore potential solutions for creating the next generation of blockchain systems.
