    摘要: The invention relates to an identification system, wherein the identifier is a body comprising an inhomogeneous material, which body is identified by subjecting it to mechanical vibrations, in particular acoustic vibrations, observing how the propagation of this mechanical vibrations is affected by inhomogeneities present in the body, and recognizing the body on the basis of a previous observation. Such an identifier body can be associated with an information carrier, allowing for the authentication of the information carrier, and for a conditional access or a copy protection scheme which can be relied upon. The acoustic identification according to the invention can be seen as an alternative to the optical identification of a body, which is known in the art, which alternative, compared to the optical identification, is characterized by higher robustness, various simplifications in the identification system and lower costs of implementation. The invention can also be applied for the generation of keys.

    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.
