1 Privacy in Biometrics
نویسندگان
چکیده
Biometric features are increasingly used for authentication and identification purposes in a broad variety of institutional and commercial systems, such as e-government, e-banking and e-commerce applications. On the other side, the adoption of biometric techniques is restrained by a rising concern regarding the protection of the biometrics templates. In fact, people are not generally keen to give out biometric traits with little assurance that they cannot be stolen or used without an expressed consent. Recent results showed that generating a unique identifier by combining biometric traits making it impossible to recover the original biometric features (thus preserving the privacy of the biometric traits) is feasible. The chapter reviews the privacy issues related to the use of biometrics and presents some of the most advanced techniques available up to date, providing a comparative analysis. and giving an overview on future trends. —

متن کاملThere is more to biometrics than user identification: Making mobile interactions personal, secure and representative
This essay contributes an extended view on user information inferred by personal devices to motivate applications of biometrics beyond user identification. We unfold a new design space in two parts: First, we take inspiration from the shared focus on individuality in both biometrics and Belk’s Extended Self (ES, [1, 2]). ES describes that people use (digital) objects to define and reflect on th...
