摘要： The present invention relates to a method and a system of verifying the identity of an individual by employing biometric data associated with the individual while providing privacy of said biometric data. A basic idea of the present invention is to represent a biometric data set XFP with a feature vector. A number of sets XFP1, XFP2, . . . XFPm of biometric data and hence a corresponding number of feature vectors is derived, and quantized feature vectors X1, X2, . . . , Xm are created. Then, noise robustness of quantized feature components is tested. A set of reliable quantized feature components is formed, from which a subset of reliable quantized feature components is randomly selected. A first set W1 of helper data is created from the subset of selected reliable quantized components. The helper data W1 is subsequently used in a verification phase to verify the identity of the individual.

摘要： An optical arrangement of at least a coherent light source (1), a strongly scattering object (5) (the PUF), and a pixe-lated photo-detector (6), wherein the pixels are comparable in size with the bright and dark patches of the speckle pattern produced by coherent radiation traversing the scattering object (5). Quantitively, the pixel size should be roughly λ/NA, where λ is the wave-length, and (i) NA=a/z for free-space geometry, with a being the beam radius and z being the distance between the exit surface of the PUF (5) and the pixelated detector (6), or (ii) NA is the numerical aperture of a lens (7) in an imaging geometry. In a preferred embodiment of the invention, there are tentative requirements that the pixels should be at least smaller than ηmaxλNA and preferably larger than ηmaxλ/NA, where (in an exemplary embodiment) ηmax=5 and ηmin=0.05, say. It will be understood by a person skilled in the art that the present invention is concerned with the optical arrangement of the PUF (5) and the photo-detector (6), rather than the photo -detector (6) per se.

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 (IIDS) 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（IIDS）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窜改环境（601,604,606）中执行安全敏感信息的处理。该处理结合利用辅助数据方案，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才能使用。

摘要： The invention relates to a system for improved copy protection comprising a record carrier like a CD-RW+ or a DVD storing copy-protected information and a device for reading from and/or writing to the record carrier. For that the record carrier (1) has a first area (3) storing information (data), which is at least partly stored in encrypted form (EAK(data)), this part being called an asset (EAK(data)), and which includes a first part of decryption information (HCK, EDNK(HCK)), and the record carrier (1) further has a second area (4) storing a second part of decryption information (UCID), wherein both the first (HCK) and second (UCID) parts of decryption information serve in decrypting an asset (EAK(data)). Such distribution of decryption information over at least two areas of the record carrier may further be combined with additional safety mechanisms as e.g. hidden channels, encrypted keys, counter mechanisms, and revocation lists.

摘要： The present invention relates to a method for transforming a feature vector comprising a first and a second feature represented by a first and a second feature value, respectively, into a feature code using an encoder, said feature code usable in an algorithm and having a predetermined number of bits, said method comprising the steps of determining for each of the first and the second features the performance as a function of the length of the feature code, and using the dependency between the performance and the feature code length for each of the individual features derived in the step of determining to find feature code lengths for the first and the second features in such a way that the sum of the bit length of the first and the second feature codes has a length equaling said predetermined bit length. An advantage with the present invention is that it solves the problem in the case of template protection systems which only accept binary templates and where the resulting classification quality of the biometric system to a very large extend depends on the quality of the binary strings. Another advantage with the present invention is that it also solves the problem of matching time in an identification setting because binary strings can easily be compared. The present invention also relates to a similar arrangement for transforming a feature vector into a feature code.
摘要翻译：本发明涉及一种用于使用编码器将包括由第一特征值和第二特征值表示的第一和第二特征分解为特征码的特征向量变换的方法，所述特征码可在算法中使用并具有预定的所述方法包括以下步骤：确定作为所述特征码长度的函数的所述第一特征和所述第二特征中的每一个，以及使用所述个体中的每一个的所述性能和特征码长度之间的相关性在确定第一和第二特征的特征码长度的步骤中导出的特征，其特征在于第一和第二特征码的比特长度之和具有等于所述预定比特长度的长度。本发明的优点在于，在仅接受二进制模板的模板保护系统的情况下解决问题，并且生物测定系统的最终分类质量在很大程度上取决于二进制串的质量。本发明的另一个优点是它也解决了识别设置中匹配时间的问题，因为可以容易地比较二进制串。本发明还涉及将特征向量变换成特征码的类似装置。

摘要： The present invention relates to a method and a system of recognizing an ear by locating an invariant point in a representation X of ear geometry. An idea of the present invention is the improve the well known Iannarelli algorithm in that the scheme of the present invention captures and processes all pixels values along an axis and may use an arbitrary number of axes to combine these pixel values to a complete feature vector with a sufficient level of discrimination. The prior art Iannarelli method is improved by performing a Fourier transformation of a polar representation e[θ, p] of the ear, whereby a transformed E[Θ/P] polar representation is created. This transformed representation is sampled to create an ear feature vector XF.

摘要： The present invention relates to a method of authenticating an individual (321) at an authenticating device (311) and an authenticating system for authenticating an individual. A basic idea of the present invention is to store, at a device or a system with which an individual wishes to authenticate herself, one or more data structures each comprising a value based on an identifier pertaining to the individual and an encrypted copy of the identifier. When the individual wants to authenticate herself, she contacts the authenticating device whereby a request is made to attain the encrypted identifier included in a specific data structure stored at the authenticating device. The individual subsequently provides proof to the authenticating device that she actually knows the identifier.
