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 secure environment permanently, but only when the individual offers her template to the sensor.

摘要： This invention relates to methods and devices for verifying the identity of a person based on a sequence of feature components extracted from a biometric sample. Thereafter, the feature components are quantized and assigned a data bit sequence in such a way that adjacent quantization intervals have a Hamming distance of 1. The data bit sequences are concatenated into a bit string, and said bit string is combined with a helper data set by using an exclusive disjunction (XOR) operation into a codeword. Finally, the codeword is decoded into a secret V and a secret S is matched with the secret V.

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.
