摘要： The invention relates to a method of authentication of a physical object and an apparatus applying said method. The method uses a helper data (Wl) and a control value (Vl) associated with a reference object to generate a first property set (Cl) using the helper data (Wl) and a metric (Y) associated with the physical object. It further comprises a step to generate a second property set (Sl) using a noise compensating mapping (NCM) on the first property set (Cl), as well as a step to establish a sufficient match between the physical object and the reference object using the second property set (Sl) and the first control value (Vl). The method is characterized by a step that generates an error measure (ERR) by quantifying the noise removed by the noise compensating mapping (NCM) using the first property set (Cl) and information derived from the noise compensating mapping (NCM). Error measure (ERR) is subsequently used for generating an authentication decision (D). Also provided is an apparatus configured to carry out the method.

摘要： A method for configuring a biometric template protected authentif ication system, in which the desired classification threshold (T) is first selected to optimize the trade-i off between FAR and FRR of the system, and then the ECC used in the authentif ication process is chosen such that the number (b) of errors which can be corrected thereby is equal to or greater than the selected classification threshold. During authentif ication, the number (b) of errors in a first codeword derived from biometric data associated with a physical object is determined and used in the decision process to accept or reject authentif ication.

摘要： The present invention relates to a system and a method of verifying the identity of an individual by employing biometric data associated with the individual (603), wherein privacy of said biometric data (X, Y) is provided. A helper data scheme (HDS) is employed to provide privacy of the biometric data. The present invention is advantageous for number of reasons. First, processing of security sensitive information is performed in a secure, tamper-proof environment (601, 604, 606) which is trusted by the individual. This processing, combined with utilization of a helper data scheme, enables set up of a biometric system where the biometric template is available in electronic form only in the secure environment. Moreover, electronic copies of the biometric templates are not available in the ecure environment permanently, but only when the individual offers her template to the sensor.
摘要翻译：本发明涉及通过采用与个体相关联的生物特征数据（603）来验证个人身份的系统和方法，其中提供所述生物特征数据（X，Y）的隐私。使用辅助数据方案（HDS）来提供生物特征数据的隐私。出于多个原因本发明是有利的。首先，在由个人信任的安全的防篡改环境（601,604,606）中执行安全敏感信息的处理。该处理结合使用辅助数据方案，可以建立生物识别系统，其中生物特征模板仅在安全环境中以电子形式提供。此外，生物特征模板的电子副本在永久环境中不可用，但只有当个人将模板提供给传感器时。

摘要： The present invention relates to an apparatus and a method of calculating an index key (140) for a template (105), the index key (140) for use in a database system applying continuous classification. The index key relates the template to a set of templates (110). The template (105) and the respective templates in the set of templates (110) each comprise a plurality of multi- value elements wherein each of the multi- value elements has one of at least three values. The method comprises calculating (125) an element-based distance metric for each template element of at least one subset of the template elements, the element-based distance metric being based on the difference of the respective template element from an average template element value computed over the set of templates (110). The precision of the element-based distance metric is determined by an estimate of the differentiating capability of the respective template element. The method further comprises generating (135) an index key (140) comprising multiple calculated element-based distance metrics. The invention further relates to a method of providing an index key for a template comprised in a database system applying continuous classification as well as a system and method of searching a candidate template in a database system applying continuous classification.
