From the reviews:

"This compact book gives the reader a complete overview of the techniques used for the encryption of digital video and images. This is evidently of deep technical interest nowadays, with the growth of applications such as pay-per-view and digital video broadcasting on demand. … It is extremely readable, even for those who are not experts in this specific field. Practitioners and students will benefit from this book. … a pleasant and interesting read for researchers from other fields who want to approach video encryption technologies." (Stefano Zanero, Computing Reviews, August, 2005)

Visual Data Formats.- Cryptography Primer.- Application Scenarios for the Encryption of Visual Data.- Image and Video Encryption.- Conclusions.

Image and Video Encryption provides a unified overview of techniques for encryption of images and video data. This ranges from commercial applications like DVD or DVB to more research oriented topics and recently published material. This volume introduces different techniques from unified viewpoint, then evaluates these techniques with respect to their respective properties (e.g., security, speed.....). 

Encryption of visual data is an important topic in the area of mutimedia security, applications range from digital rights management (DVD, DVB) ) to secure personal communications.  Within this topic area, we face several aims which contradict each other.  What we thrive on is good compression, fast compression, high security, fast encryption, bitstream compliance, little power consumption and little memory requirements. 

The authors experimentally compare different approaches proposed in the literature and include an extensive bibliography of corresponding published material.

Image and Video Encryption is designed for a professional audience composed of researchers and practitioners in industry.   The  book is also suitable for graduate-level students in computer science and electrical engineering.
