A unifying view on template protection schemes
نویسندگان
چکیده
We show that there is a direct relation between the maximum length keys extracted from biometric data and the error rates of the biometric system. This information can be used a-priori to evaluate the potential of the biometric data in the context of a specific cryptographic application. We model the biometric data more naturally as a continuous distribution and we give a new definition for the fuzzy extractor that works better for this type of data. We give three examples in this sense.

An Improved Biometric Template Protection Method based on Non-Uniform Quantization
In recent literature, the issue of biometric template protection was raised. Some schemes were proposed to solve the contradiction between the fuzzy biometric information and accurate cryptography functions to achieve the protection of biometric template via cryptography method. In this paper, a novel methodology to achieve the security of the biometric templates in biometric systems is propose...
متن کاملTemplate Protection under Signal Degradation: A Case-Study on Iris-Biometric Fuzzy Commitment Schemes
Low intra-class variability at high interclass variability is considered a fundamental premise of biometric template protection, i.e. biometric traits need to be captured under favorable conditions in order to provide practical recognition rates. While performance degradations have been reported on less constraint datasets detailed studies based on a certain ground truth have remained evasive. ...
متن کاملImage Compression in Iris-Biometric Fuzzy Commitment Schemes
Template protection targets privacy and security risks caused by unprotected storage of biometric data. Meeting properties of irreversibility and unlinkability template protection systems can be applied to secure existing records within biometric databases, i.e. without re-enrollment of registered subjects. The National Institute of Standards and Technology (NIST) demonstrated that iris recogni...
متن کاملIris-Biometric Fuzzy Commitment Schemes under Image Compression
With the introduction of template protection techniques, privacy and security of biometric data have been enforced. Meeting the required properties of irreversibility, i.e. avoiding a reconstruction of original biometric features, and unlinkability among each other, template protection can enhance security of existing biometric systems in case tokens are stolen. However, with increasing resolut...
متن کاملUnlinkable and irreversible biometric template protection based on bloom filters
Deployments of biometric technologies are already widely disseminated in numerous large-scale nation-wide projects. Since the protection of biometric reference data is of particular concern in order to safeguard individuals’ privacy, biometric template protection schemes are designed to handle biometric reference data in an irreversible and unlinkable manner. In past years, schemes based on Blo...
