"From the reviews: ""Secure data management in decentralized systems is addressed in this book. … This book should appeal to researchers and graduate students who want to acquire in-depth knowledge of information security and its extension to distributed database systems. After reading the book closely, one will have a better understanding of the new set of issues and the complexity of securing distributed data in emerging environments.""
