What People are Saying About This

From the Publisher

With more and more regulations focusing on protection of data privacy and prevention of misuse of personal data, anonymization of sensitive data is becoming a critical need for corporate and governmental organizations. This book provides a comprehensive view of data anonymization both from a program sponsor’s perspective as well as a practitioner’s. The special focus on implementation of data anonymization across the enterprise makes this a valuable reference book for large data anonymization implementation programs.
Prasad Joshi, Vice President, Infosys Labs, Infosys Ltd.

This book on data anonymization could not have come at a better time, given the rapid adoption of outsourcing within enterprises and an ever increasing growth of business data. This book is a must read for enterprise data architects and data managers grappling with the problem of balancing the needs of application outsourcing with the requirements for strong data privacy.
Dr. Pramod Varma, Chief Architect, Unique Identification Authority of India
