Regulation, risk awareness and technological advances are more and more drawing identity search requirements into business, security and data management processes. Following years of struggling with computational techniques, the new linguistic identity matching approach finally offers an appropriate way for such processes to balance the risk of missing a personal match with the costs of overmatching. The new paradigm for identity searches focuses on understanding the influences that languages, writing systems and cultural conventions have on person names. A must-read for anyone involved in the purchase, design or study of identity matching systems, this book describes how linguistic and onomastic knowledge can be used to create a more reliable and precise identity search.
