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 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： 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.

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： 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.
