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： A basic idea of the present invention is to selectively employ one of at least two different feature extraction processes when generating a biometric template of an individual. An individual offers a physiological property, such as a fingerprint, an iris, an ear, a face, etc., from which biometric data can be derived, to a sensor of an enrollment authority. In the following, the property to be discussed will be fingerprints, even though any suitable biometric property may be used. From the fingerprint, a positional reference point of the biometric data is derived. The derivation of the positional reference point may be accomplished using any appropriate method out of a number of known methods. Such a reference point could be the location of a core, a delta, a weighted average of minutiae coordinates, or alike. Typically, the reference point includes a core of a fingerprint expressed as a three-dimensional coordinate denoted by means of xr, yr, and angle αr. A contribution indicator is calculated for the derived positional reference point, and it is determined whether the derived positional reference point can be considered reliable. Depending on the reliability of the derived reference point, one of the two different feature extraction processes is selected; either the first feature set is extracted using a method which is invariant of the derived reference point, or a method is used taking into account the derived reference point. The better the estimation of the reference point is, the more reliable the reference point-dependent extraction method is. Finally, the biometric template is generated using the extracted first feature set.

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 (W1) and a control value (V1) associated with a reference object to generate a first property set (C1) using the helper data (W1) and a metric (Y) associated with the physical object. It further comprises a step to generate a second property set (S1) using a noise compensating mapping (NCM) on the first property set (C1), as well as a step to establish a sufficient match between the physical object and the reference object using the second property set (S1) and the first control value (V1). 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 (C1) 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 relative movement sensor for measuring movement of an object (15) and the sensor relative to each other, the sensor comprising a plurality of lasers (3,5) for generating respective measuring beams and illuminating the object (15) therewith, and a plurality of respective photodiodes (4,6) for measuring changes in operation of each laser cavity caused by reflected measuring beam radiation re-entering the respective laser cavity and the optical wave in the laser cavity. The plurality of lasers (3,5) are operated in a time-multiplexed manner such that only a subset (i.e. one or more) of the lasers is operated at any one time, the remaining lasers being idle. This reduces peak power dissipation and prevents erroneous interference caused by measuring beam radiation from one laser entering the cavity of another laser.

摘要： The present invention relates to a method and a system of determining correspondence between location sets. A basic idea of the present invention is to provide a scheme in which correspondence between location sets is determined. A feature location set (X) comprising a number (n+1) of components is transformed into a feature vector that can be used in an HDS. Therefore, a feature density function (ƒjs(x)) is created. A feature vector (XF) for the HDS is chosen to be a sampled version of the feature density function (ƒX,g(x) ), which results in feature vectors of equal and finite dimensions regardless of the number (n+1) of features that are present in the biometric template XT from which the location sets is derived. Thereafter, a distance (d) between two feature location sets (X, Y) is determined. The distance (d) between the sets is chosen to be the Euclidian distance between the corresponding feature density functions.
