Definitions

  • the invention relates to a method for identity verification as a prerequisite for granting access and / or exercise authorization, in which at least one data record is generated on the basis of biometric features with the aid of a data acquisition and data processing system and in which the proof of identity is used of the underlying biometric features.
  • the invention also relates to arrangements for carrying out this method.
  • the patent DE 43 22 44 5 Cl describes a method for coding identification cards by means of fingerprints, in which a number of fingerprints are taken from the holder of the identification card with the aid of a sensor, and an imprint of the removed fingerprints is applied to the identification card as a key code is selected and after a processing key at least one of the other fingerprints is used as the identification code and is saved.
  • the key code fingerprint can be stored, for example, in the form of a hologram.
  • the method proposed here provides that the card holder inserts his identification card into a fingerprint comparison device and places a plurality or all of the fingers of both hands on a fingerprint sensor. There is a comparison of the fingerprint stored on the card with one of the natural fingerprints, after which, in the event of a positive comparison, an access to a memory is opened by means of an output signal which contains the fingerprint of the cardholder selected according to a scrambling system.
  • This memory can be a local terminal at the location where the card is used.
  • a central terminal is also proposed, which is connected to the fingerprint comparison device on site. With the open access to the memory, a comparison of the stored fingerprint with the transmitted fingerprints and, if the stored fingerprint matches with one of the transmitted fingerprints, the identification card is released.
  • a fingerprint scanning device is used for identity verification, in which an image input device is coupled to a storage device for the photoelectronic storage of fingerprints of registered persons.
  • a feature recognition device processes the image data and generates a spectra pattern.
  • a determination device identifies the person entering as a registered person.
  • An output signal device generates an unlocking signal and sends it to a door locking device.
  • a line thinning is provided in the feature recognition device used here, which separates the thick elements of the fingerprint lines from the two-dimensional fingerprint data that have been transmitted from a CCD camera to the feature recognition device. Furthermore, the feature recognition device a middle position recognition device which determines the middle section of the two-dimensional fingerprint data. Furthermore, a data recognition device is provided which recognizes a fingerprint section within a certain radius from the center position in order to present it as identification data. On the basis of this determination data, a two-dimensional Fourier transformation takes place, the result of which is the two-dimensional Fourier-transformed image which is recorded as a spectra pattern.
  • the invention has for its object to provide a method of the type described, in which, in contrast to the prior art, no permanent storage of data records is required, which are obtained from biometric sources and whose content is shaped by the characteristics of these biometric sources.
  • the object of the invention is achieved in that a first data set is generated from random data without reference to the characteristics of a biometric source and is stored on a data carrier as a control data set. Since this data set is based on random data, it does not allow any conclusions to be drawn about a biometric source of origin, even when evaluated by unauthorized persons.
  • This first data record is assigned as a tax data record to one of the persons belonging to the group of persons authorized to access. It will be saved permanently at least until the next access request is drawn.
  • the person authorized to access calls the first data record from the memory; in addition, the character Teristic biometric features of a biometric source to be identified of the person requesting access, for example the characteristic of a fingerprint, are recorded in the form of a feature data record, which is, however, not stored permanently, but is provided temporarily for linking to the control data record.
  • At least some of the feature data and at least some of the control data record are now transformed into a second data record by an irreversible arithmetic operation.
  • This second data record created in this way is used as a characteristic data record for granting access and / or exercise authorization and / or as a cryptographic key.
  • the data which have a reference to the characteristics of the biometric source, are not permanently stored in a memory and thus an uncontrollable access to this data is not possible.
  • the method according to the invention does not provide a YES / NO decision on the access authorization, but rather a value corresponding to the characteristic data record within a certain value range, the value range being able to be predetermined by the amount of the data to be recorded and processed.
  • This value which corresponds to the characteristic data record, is subsequently used as the basis for a YES / NO decision on access authorization. With each access request, this value or characteristic data record is regenerated from the combination of the permanently stored control data record with the currently obtained temporary biometric data. Only one value out of the total possible amount of achievable values is correct.
  • the second data set is unambiguous with regard to the combination of the tax data set with the biometric data which are recorded by the person requesting access; however, it is not unique in relation to the biometric data read in alone. A comparison of images or structures to identify the biometric source (fingers, facial features or voice) is no longer possible.
  • the second data record which is generated in the manner described and is intended to serve as an access criterion, is always related to the data read in and is generated anew and differently with every entry request, even if it is the same person. At the same time, however, this means that it is not possible to predict the content of the second data record generated during the next and the next but one access request, even if the same biometric data are used. This ensures that it is not possible for unauthorized parties to draw conclusions about the biometric data or to preview the data records that are generated as requests for access.
  • This symbolically means that as a prerequisite for access, a key for an existing lock is not necessary as was previously the case, but for each new access a new, unpredictable lock has to be overcome and an unknown key is required for this.
  • the second data record together with the name of the user, is used as a criterion or password for an examination, access and / or exercise authorization is only granted to those who meet the corresponding identity requirement.
  • a very preferred development of the invention consists in the fact that the computing operation for transforming the data takes place according to a cryptographic HASH function. This ensures that the transformation is irreversible with a high degree of certainty.
  • the HASH function converts a variable variable, for example any set of values, into a fixed string.
  • the arithmetic operation is easy to perform for any value, but is not reversible. Input sizes of any length become output sizes of fixed length, which briefly but precisely reproduces the original information.
  • the characteristic biometric features are recorded multiple times in order to achieve sufficiently reproducible feature data, and a feature extraction is carried out after each data acquisition. This has the advantage that later identification is possible with greater certainty.
  • the feature extraction can be carried out by multiple image recognition and "minutiae detection” analogous to forensic processing.
  • control data record can be stored uncoded on the data carrier without the risk of unauthorized decryption.
  • the method according to the invention can be applied very well on the basis of the biometric data of a finger, it can also be used in another way, e.g. based on the shape of the face or based on the voice.
  • the recording of the characteristic biometric data is carried out by capturing electronic image information, whereas when the voice is used as the basis, the data to be stored are generated using an electronic sound image.
  • This control data record has no relation to the characteristics of the user or to a biometric source.
  • the characteristic biometric features of a particular finger of this new user are recorded with high reproducibility using a high-resolution optical system, and a feature data record is obtained therefrom, which is not permanently stored on a data carrier, but is only used temporarily for linking to the control data record.
  • control data record and the feature data record are generated by an irreversible arithmetic operation, for example likewise by means of the arithmetic circuit according to
  • HASH function H (m) f ⁇ y ⁇ , transformed into a characteristic data record.
  • This characteristic rate corresponds to a specific numerical value that is used as the basis for a YES / NO decision on access authorization.
  • this value or the characteristic data record is regenerated from the combination of the permanently stored control data record with the currently obtained temporary biometric data.
  • this value or the characteristic data record is regenerated from the combination of the permanently stored control data record with the currently obtained temporary biometric data.
  • the user is first asked to enter his name using the keyboard, whereupon it is checked whether the user name is known; if the result is positive, the control data record is activated.
