Definitions

  • Biometric characteristics such as fingerprint patterns, iris patterns, and similar characteristics of a person are characterized by their uniqueness and immutability. Therefore, every person can be easily recognized by such biometric features with the help of information technology systems.
  • a secret password is also a characteristic of a person, as long as the password has not been revealed. Biometric characteristics and passwords are therefore generally well suited for the purposes mentioned.
  • Modern biometric verification methods initially record the biometric characteristics of a person using a special sensor as raw data.
  • the actual features can be extracted from this raw data using special algorithms.
  • the verification or identification is then carried out by comparing a stored set of reference features with the current features.
  • the object of the invention is to improve this situation. This object is achieved with the aid of an arrangement for recording and evaluating data or signals with features according to claim 1 or by a method for checking the identity or authorization of a person with features according to claim 5.
  • the invention is based on the idea of not transferring the data characteristic of a person to a third-party system, but of capturing this data or signals by an arrangement which is in the possession of the authorized person, and with the aid of this arrangement input data which the Receives the order from a third-party system to be encrypted, so that the third-party system does not recognize the authorization of the person by their characteristics, which are to be protected, but by the correct encryption of the input data.
  • Input data encryption takes place within the arrangement that is particularly secured against unauthorized access. This effectively protects a person's characteristic data against misuse.
  • FIG. 1 shows the structure of a preferred embodiment of the invention in a schematic manner and at the same time illustrates the sequence of a method according to the invention.
  • An arrangement according to the invention for recording and evaluating data or signals, in particular for checking the identity or authorization of a person, etc., comprises a device (DE) for recording data (D) or signals (S) and a device (DV) for Checking the recorded data or signals within the arrangement and a device (KE) for encrypting input data (ED) within the arrangement.
  • DE device
  • D data
  • S signals
  • DV device
  • KE device
  • ED encrypting input data
  • the device for acquiring data or signals can be a simple keyboard of a computer or communication terminal or another small device.
  • a graphical input medium such as e.g. a pressure-sensitive input surface, perhaps with an underlying display, can be used.
  • Such input devices are particularly suitable for entering passwords or signatures.
  • the device for recording data or signals can also be a microphone, or a camera, or a
  • Fingerprint sensor Further devices, in particular for recording biometric characteristics of a person, are conceivable.
  • the recorded data or signals can include anything from text, numbers, lettering, to voice samples, spoken words or sentences, all for identification or for
  • the user can therefore be sure, at least as long as he remains in the exclusive possession of the arrangement and can rule out interference by unauthorized persons, that his data cannot be misused. Passes the exam successful (positive), ie if the recorded data and signals indicate an entry by an authorized user in the sense of checking, input data (ED), which are supplied to the arrangement from outside, are encrypted with the help of a device (KE) the arrangement is encrypted.
  • ED input data
  • KE device
  • An external system can now check the correct encryption of the input data and thus the identity of the person or your authorization at any time. All that is required is to read out and check the encrypted input data. The characteristic data of the person remain in the arrangement and are therefore protected against misuse.
  • the personal data can be checked within the arrangement in many different ways.
  • Another possibility is to supply the characteristic data to a decision function, which directly determines the test result in the form of a yes / no decision.
  • the simplest, however, is probably the direct comparison of the data, signals or feature data with reference data (RD) stored in a memory device (SEI) of the arrangement.
  • RD reference data
  • SEI memory device
  • the key (K) is not calculated directly within the arrangement, it is advantageous to store it in a storage device (SE2) within the arrangement.
  • SE2 storage device
  • Another possibility would be to use a "hard-wired" encryption algorithm, in which the key is implicit in the architecture is hidden from the circuit.
  • this method has the disadvantage of more complex production.
  • the explicitly stored key is the only person-specific parameter of an otherwise universal arrangement.
  • asymmetrical key pairs are particularly suitable.
  • the key (K) would be the private key of the authorized person, which is to be kept secret.
  • the public key would be used to decrypt the encrypted input data in a third-party information system that wants to check the identity or authorization of the person.
  • Random or pseudo-random sequences of characters, numbers or symbols are particularly suitable as input data (ED), the correct encryption of which can easily be checked by the checking external system and which can practically not be predicted or guessed by an attacker.
  • the return time of these symbol rims should also be sufficiently long, i.e. be practically infinitely long.

Abstract

Des données secrètes ou spécifiques d'une personne sont protégées de l'agression d'un tiers, lors du contrôle de l'identité ou de l'autorisation d'une personne, en effectuant le contrôle de ces données dans une zone protégée. Si le résultat du contrôle est positif, des données d'entrée venant de l'extérieur sont chiffrées par un code mémorisé à l'intérieur de la zone protégée. Les données d'entrée chiffrées sont sorties. L'identité ou l'autorisation peut alors être contrôlée par décryptage.
