Definitions

• the present invention relates to a biometric authorization control method, by automatic comparison a currently sensory recorded biometric feature a person with a first plurality of stored records, the the corresponding biometric feature of the first Represent a plurality of authorized persons, and by respectively calculating a match score, the Authorization is detected when a match measure above a predetermined threshold.
• An important application of such methods relates to access control to buildings or to certain security areas in buildings.
• Other applications are e.g. authorizations, to open a particular locker, a cash machine too operate or the like.
• the biometric feature may be e.g. for fingerprints, Facial features or iris traits act.
• Sensory Recording is understood as any image-like recording, be it through a capacitive fingerprint sensor chip, a camera, a CCD (Charged Coupled Device) or like.
• Minutia are the terminations and ramifications of skin ridges in skin imprint pictures.
• Conventional methods take into account the positions (in X / Y coordinates) of the minutiae in order to compare these position data with those stored fingerprint data sets from a database and to calculate a similarity value or a measure of conformity. If this match is above a certain threshold, then the person is considered positive identified or suggested in a hit list, and if the similarity value is below the threshold, the person is considered not to be identical or unidentified.
• Such a method according to the preamble of claim 1 is known for example from EP 0 366 850 B1.
• a biometric Authorization control device with a biometric sensor for receiving a biometric feature of a person, a data processing unit in which a first plurality Data records is stored that the corresponding biometric Feature of a first plurality of authorized persons represent, and which is prepared, the currently sensory recorded biometric feature data of a person those of the first plurality of records to compare, respectively to calculate a metric and the authorization determine if a match above a given Threshold value is found, characterized that the data processing unit continues to be prepared if no authorization is found for a person could, the biometric feature of this person with a second Compare a plurality of stored records that the appropriate biometric feature of a variety of unauthorized People represent, each a measure of agreement and, if doing so, a match measure above the predetermined threshold is found, data store the unauthorized access attempt.
• the second plurality of records may be e.g. the biometric data of unwanted or wanted persons include.
• the first plurality of records e.g. to include the persons the one authorization for access in a security area within the company, while the rest Employees who are only to the other parts of the building Company are authorized to access in the second records are recorded. If an unauthorized employee repeatedly tried to unauthorized access to the security area This can be done by registering the attempts are recorded and the employer is allowed to to take further security measures.
• biometric Feature one or more fingerprints of each person used.
• biometric Data the prints of several fingers for each person used; depending on the selection of a particular finger can do so selectively starting each one of a plurality of preprogrammed ones Functions be triggered.
• a security application can e.g. the capture of the fingerprint of a A person's finger may be provided to open a door Detecting another finger to trigger a covert alarm and that of another finger, to an open alarm trigger. This could be z. B. at an ATM or vault Serve that by selecting a specific finger Alarm or covert alarm can be triggered if one Person is forced to pay out or vault opening. On In this way a maximum of ten functions can be coded.
• the number of triggerable preprogrammed function can be increase considerably if, in addition, the circulation frequency different finger on the fingerprint sensor is detected and thereby selectively starting each one of a plurality of pre-programmed functions. If the multiple Applying a single finger is required and the number the circulation attempts are exceeded or fallen short of, the Authorization denied and e.g. the access refused. Farther can with a simple hang up a finger a certain Function are triggered, with two hang up Finger's another function and when thrown three times Fingers in turn trigger another function etc ..
• the number of triggerable preprogrammed function can be in addition, once again increase significantly, if the order the overlay of different fingers on the fingerprint sensor is detected, thereby selectively starting each one can be triggered from a large number of preprogrammed functions is.
• the pre-programmed functions can be triggered automatically an open alarm, a covert alarm, an emergency call or closing one or more doors; Furthermore, in this way, further security levels or Authorization levels are introduced.
• authorization control process is e.g. in the field of motor vehicle security. For example, it may be provided that the start of the engine only be triggered when the driver puts one of his fingers up a fingerprint sensor hangs up in the vehicle. simultaneously this authorization control can also be used to to identify the respective driver and corresponding individual settings in the motor vehicle automatically to make, e.g. Seat and mirror settings. By hanging up Other fingers may have other functions in the motor vehicle be authorized or triggered.
