Definitions
- the invention relates to a method and a device for user identification for the unique identification of a user or participant of a system.
- Such a system can be, for example, a terminal device such as a cell phone or a building to which only certain people should have access.
- a terminal device such as a cell phone or a building to which only certain people should have access.
- it can also be a computer network which only allows access to certain data after the user has been clearly identified, for example in online banking.
- PIN personal identification number
- biometric identification methods have recently been developed in which biometric features of a user are used for authentication.
- Such a biometric identification is not a simple, but comfortable and often very secure method of ensuring the assignment and access of a specific person to a system or a location.
- the advantage of biometric identification compared to the PIN code is that it cannot be forgotten and the biometric features can only be copied with great effort or not at all.
- the PIN code is pure software, there is always a more or less unambiguous assignment to the hardware, ie to the body of the respective user, for biometric features.
- One way of such a bio Metric identification consists of capturing the fingerprint of a user's finger.
- a computing unit compares the recorded fingerprint features, such as branches or minuscules, with the features of stored fingerprints of persons with access authorization. If there is a certain degree of agreement, which allows a clear identification of the user with a very high probability, the use is released.
- the invention is therefore based on the problem of proposing a method for user identification by means of biometric data, in particular fingerprint data, in which a false identification due to traces of a previous identification process that are left behind is avoided.
- an identification method comprising the steps (I) of capturing a biometric data record of the user and the respective spatial position of the biometric data relative to a reference position, (II) storage of the biometric data set and the associated position data,
- the invention is based on the fact that, as a rule, a user is unable to position the finger in the vertical and horizontal directions with an accuracy of less than 100 .mu.m when it is placed on the sensor again. If a matching fingerprint is detected in a matching position during two successive identification processes, it is assumed that in the second identification process only the imprint traces remaining from the previous identification process are misused and the access authorization is refused.
- the invention also proposes a device for biometric user identification with the features of claim 8.
- Advantageous developments of the method according to the invention and the device according to the invention are described in the subclaims.
- an average of the positions of a plurality of individual features of the biometric data is determined when the biometric data record is acquired, and these average position values are compared with one another when the position comparison test of two successive identification processes is carried out. Since the mean values of less scattering, for example due to an elongation or With this method variant, the tolerance range within which a position match is assessed as misuse can be selected more narrowly, so that an undesired non-recognition of a finger correctly placed twice in succession becomes less likely.
- FIG. 1 shows a schematic block diagram of an exemplary embodiment of the device according to the invention
- FIG. 2 shows a flow chart for explaining an exemplary embodiment of the method according to the invention
- FIG. 3 shows a flow chart to explain a further exemplary embodiment of the method according to the invention.
- a fingerprint sensor 1 has a support field 5 for supporting a finger (indicated by dashed lines) and detects the features such as branches or minus muscles of the fingerprint.
- a position detection device 2 detects the positions of these features relative to a reference position, for example a coordinate origin of an xy coordinate system of the support field 5.
- the fingerprint data determined in this way and associated position information are fed to a memory 3 and a comparison device 4.
- the corresponding fingerprint data and position data of the previous fingerprint acquisition are read out from the memory 3 and likewise fed to the comparison device 4. There, the fingerprint features and their positions are compared and, if there is a match, within a
- the comparison device 4 evaluates the current fingerprint acquisition or the current ID tification process as abusive use of fingerprint traces of the last identification process and refuses access, which is displayed on a display device 6.
- the invention is based on the fact that
- old fingerprint traces no longer play a role when repositioning any finger and are replaced by the reprint and (2) that a user is unable to position the finger when it is replaced so precisely that the finger is in position and direction up to 100 ⁇ m or 50 ⁇ m matches the previous fingerprint.
- step S1 the biometric data and their associated positions on the support surface are recorded. These are used in a step S2 for use in the next stored user identification process. Accordingly, the biometric data and associated positions of the preceding identification process are read out in step 3.
- step S4 a comparison is made as to whether the features and positions of the two successive acquisitions, ie the fingerprint acquisition of the current user identification process and the fingerprint acquisition of the immediately preceding user identification process, match. If both the characteristics of the fingerprint have a fixed degree of agreement and that
- step S5 If these features coincide within a tolerance range of 50 ⁇ m or 100 ⁇ m, the identification is rejected (step S5), otherwise the check proceeds to step S6, in which, as in the case of known user identification methods, it is checked whether the features of the current detection of the Fingerprint with the stored characteristics of fingerprints of certain people, for example authorized users. If this is not the case, the identification is rejected (step S7), otherwise the identification takes place.
- step S4 the positions of individual features of the fingerprints are not compared with one another, but rather the average position values of the current and the previous fingerprint acquisition. This has the advantage that statistical deviations due to elongation or
- the invention provides an improved method for biometric user identification, in which misuse due to fingerprint traces of a previous user identification process remaining on the recording device can be avoided.
- the invention is applicable to the checking of the authorization to use devices such as mobile phones or to identify a computer user in bank transactions.
- biometric data such as a fingerprint.
