Abstract: A data carrier has stored thereon a secret code and a user's biometric data. In using the data carrier, a data carrier terminal is first authenticated for access to data stored in the data carrier by reading a secret code from the data carrier in a manner known only to an authorized terminal, and then displaying the read secret on the data carrier terminal. If the user determines that the displayed secret code is correct, the user then presents a biometric feature which is read and compared to the biometric data stored on the data carrier. If the read biometric data matches the stored biometric data, then the user is authorized for further use of the data carrier on the data carrier terminal.

Abstract: The present invention relates to devices and a method for biometric authentication by means of reference data stored in a memory of a portable data carrier. For biometric authentication methods to make their final breakthrough with respect to more widespread use, there is a need for standardized generation of reference data for the particular biometric features used for authentication. Different suppliers of methods and devices for biometric authentication have hitherto used algorithms for generating the reference data which normally lead to different reference data which are not interchangeable. This limits the employability of biometric methods to the supplier's particular system. The present invention avoids this problem by storing several sets of biometric reference data, thereby increasing the likelihood of the evaluation of at least one set of stored biometric reference data being possible. Thus, the desired system-independent authentication can be attained.

Abstract: A method, apparatus and system for biometric authentication of a person are proposed. Since the detection of biometric data never matches 100 percent, authentication is already effected when the detected data exceed a defined threshold value in comparison to stored reference data. In order to increase security, the invention provides that information about the person's individual properties influencing the biometric data is stored and taken into account in the authentication process. For example, the threshold value is set low upon comparison of a fingerprint only if the person has exceptionally dry or moist skin. On the other hand, the sensor for detecting the biometric data of the fingerprint can also be set to be more sensitive or less sensitive depending on the stored information.

Abstract: A method and an apparatus for testing a biometric feature wherein a set value of the biometric feature is stored in a data carrier in the form of one or more data records. For testing the biometric feature, measured values representing an instantaneous value of the biometric feature are first determined and made available in a terminal. The data carrier transmits to the terminal at least a subset of first reference values depending on the data record or data records for the set value. The terminal links data derived from the measured values with the subset of first reference values and transmits the result of the link to the data carrier. The data carrier tests the result of the link and determines therefrom whether the biometric feature is authentic.

Abstract: It is proposed to combine the advantages of PIN-based protection systems and biometry-based protection systems and avoid the disadvantages of the respective systems by generating the PIN biometrically uniquely. For this purpose it is provided that only characteristic data that are uniquely reproducible are derived from the determined biometric raw data. On the basis of these uniquely reproducible characteristic data a key record is then generated that either constitutes the PIN code or is used to generate the PIN code. The PIN code is thus always reproducible uniquely on the basis of the biometric data. The user need no longer remember the PIN code, and the PIN code cannot be passed on to third parties.

Abstract: The invention provides for a method of forming discrete solder portions (16) on respective contact pads (10) whereby a strip of solder paste (12) is formed over a plurality of said pads (10). The strip (12) is formed with portions of reduced width (14) which are located over the spaces (22) between adjacent pads (10). The paste is melted and the surface tension at the portions of reduced width (14) causes the movement of solder towards the pads (10) and the separation of the strip (12) into discrete solder portions (16).

Abstract: A printed circuit board assembly which includes a two-dimensional array of connectors to provide significantly higher data transfer rates than typical one-dimensional connectors, without sacrificing board space. The assembly preferably includes a plurality of connection pads on each printed circuit board. An anisotropically conducting material is placed between the connection pads and the boards pressed together.
