Book Description
Cryptology, for millennia a "secret science", is rapidly gaining in practical importance for the protection of communication channels, databases, and software. Beside its role in computerized information systems, cryptology is finding more and more applications inside computer systems and networks, extending to access rights and source file protection. The first part of this book treats secret codes and their uses - cryptography - before moving on to the process of covertly decrypting a secret code - cryptanalysis. Spiced with a wealth of exciting, amusing, and occasionally personal stories from the history of cryptology, and presupposing only elementary mathematical knowledge, this book will also stimulate general readers.

Book Description
A vital instrument of power, telecommunications is and has always been a political technology. In this book, Headrick examines the political history of telecommunications from the mid-nineteenth century to the end of World War II. He argues that this technology gave society new options. In times of peace, the telegraph and radio were, as many predicted, instruments of peace; in times of tension, they became instruments of politics, tools for rival interests, and weapons of war. Writing in a lively, accessible style, Headrick illuminates the political aspects of information technology, showing how in both World Wars, the use of radio led to a shadowy war of disinformation, cryptography, and communications intelligence, with decisive consequences.

Book Description
This media history explores a series of portable small cameras, playback devices, and storage units that have made the production of film and video available to everyone. Covering several storage formats from 8mm films of the 1900s, through the analogue videotapes of the 1970s, to the compression algorithms of the 2000s, this work examines the effects that the shrinkage of complex machines, media formats, and processing operations has had on the dissemination of moving images. Using an archaeological approach to technical standards of media, the author provides a genealogy of portable storage formats for film, analog video, and digitally encoded video. This book is a step forward in decoding the storage media formats, which up to now have been the domain of highly specialised technicians.
