This professional book discusses privacy as multi-dimensional, and then pulls forward the economics of privacy in the first few chapters. This book also includes identity-based signatures, spyware, and placing biometric security in an economically broken system, which results in a broken biometric system. The last chapters include systematic problems with practical individual strategies for preventing identity theft for any reader of any economic status. While a plethora of books on identity theft exists, this book combines both technical and economic aspects, presented from the perspective of the identified individual.
