Definitions

  • the invention relates to a method for biometric access control according to claim 1 and a corresponding device according to claim 18.
  • biometric access control which evaluate at least one characteristic feature of a living being, in particular a human being.
  • the evaluation of a person's fingerprint or image is known.
  • the fingerprint is so well suited for biometric access control, since it uniquely identifies almost every person.
  • Further characteristic features suitable for identifying a person result from evaluating the iris or iris, the facial lines, the voice or also the handwriting of a person.
  • biometric access procedures can also process dynamic components during access control. For example, in the dynamic recognition of a man's handwriting, the time course of the handwriting is evaluated during an access control. To do this, a person must provide a written sample before the access control.
  • biometric access control Another important aspect of biometric access control is user acceptance of the control. This is characterized above all by the user-friendliness and reliability. In order to achieve a high degree of user-friendliness, biometric access control by users should not be perceived as annoying or should even be rejected entirely. In order to achieve a high level of reliability, the likelihood that legitimate users are incorrectly rejected (the so-called FRR: False Rejection Rate) should be as low as possible. In order to achieve a high level of security, on the other hand, the likelihood that a wrong, illegitimate user will be accepted should be low (so-called FAR: False Acceptance Rate).
  • the object of the present invention is to propose a method and a device for biometric access control which, on the one hand, offer a high level of security against forgery and, on the other hand, offer user acceptance due to their easy handling.
  • An essential idea of the invention is based on at least partially evaluating at least one characteristic feature of the movement, in particular of the gait, of a living being as a biometric feature.
  • the gait or more precisely the gait behavior of a living being, preferably a human, is evaluated for a biometric access control. It has been found that the walk of a living being as a biometric feature offers approximately the same security against counterfeiting or deception as, for example, the dynamic handwriting recognition. Characteristic information about the living being can therefore be determined by an at least partial evaluation of the movement of a living being biometric access control can be used to advantage.
  • Living being the acceleration from a resting position of the living being, the direction of steps of the living being, the walking speed and / or the walking frequency of the living being. All of these factors can be used for evaluation as a characteristic feature of the movement of the living being, in particular since data for automatic processing can be derived from them.
  • the at least one characteristic feature is measured in a preferred embodiment of the invention with at least one sensor on the living being.
  • the at least one sensor can comprise an acceleration sensor that measures and stores the speed and direction of movement of the living being. With the movement data measured in this way, as with dynamic handwriting recognition, at least one characteristic feature of the locomotion or the gait behavior of a living being can be determined.
  • the acceleration sensor is preferably a monolithic silicon acceleration sensor with at least one bending beam etched in silicon and having strain sensors doped into it.
  • the acceleration sensor can be a capacitive monolithic silicon acceleration sensor.
  • One advantage of the monolithic silicon acceleration sensors is in the fact that these are very small and can therefore be integrated, for example, in a person's clothing, without this having a significant effect, for example, on the weight of the clothing and thus on the wearing comfort.
  • acceleration sensors are standard components and thus mass products that are inexpensive on the one hand and technically sophisticated on the other hand and therefore reliable.
  • the company Analog Devices GmbH offers acceleration sensors under the name ADXL202 / 210. With these acceleration sensors, speed and location vectors can be determined directly in both analog and digital form by integration.
  • the at least one sensor is preferably placed in or on a shoe, in particular in the heel and / or the sole of the shoe.
  • Shoes are particularly well suited for the inclusion of such sensors, since many people wear shoes every day and there is therefore little danger that a person will be refused biometric access control because they do not carry their access ID with them. In addition, there is little risk that shoes, such as ID, will be lost or even stolen by a thief. According to the invention, even if an unauthorized person is in possession of the shoes, unauthorized access to a secure system is hardly possible, since the unauthorized person would have to copy the walking behavior of the shoe owner, which is very unlikely.
  • the at least one sensor can also be placed in a shoe insert. This makes it possible to retrofit shoes with the sensor.
  • the at least one sensor in or on a foot strap that can be attached to a foot of the living being.
  • This solution is particularly suitable for people who do not own and / or want to wear shoes or shoe inserts with the sensor. In order to nevertheless give these persons access to a system secured by the method according to the invention, they can put on the foot strap.
  • the at least one sensor sends data wirelessly by means of radio and / or infrared in order to obtain access to a secure room or a computer system, for example.
  • it transmits data to a recipient in one
  • Access control device As a result, a person does not have to put down the at least one sensor for an access control in order to insert it, for example, into a reading device of an access control device.
  • the wireless transmission of data can take place, for example, using Bluetooth or in accordance with the DECT standard, which is widespread in cordless telephones.
  • all other wireless transmission methods are conceivable, which transmit data preferably over short distances between transmitter and receiver with low transmission power.
  • Embodiment of the invention transmitted encrypted. All common, in particular symmetrical encryption methods can be used for this.
  • the at least one sensor is replaced by one
  • Piezo element supplied with electrical energy is placed on the living being in such a way that it generates a piezo voltage when the living being moves.
  • This embodiment does not require a battery for power supply. As a result, it is no longer necessary to change the battery.
  • the at least one sensor and additional circuit elements as well as the piezo element can thus be firmly integrated into a shoe.
  • the piezo element can be integrated in the heel or sole of the shoe in such a way that when the shoe appears, pressure is exerted on the piezo element, so that it generates an electrical voltage to supply the generated at least one sensor. It would also be conceivable to implement the piezo element in a shoe insert which, like the heel, is regularly burdened by pressure when moving.
  • the at least one sensor can have an evaluation circuit for processing signals from the at least one sensor and processing for transmitting the processed signals.
  • the evaluation circuit can be integrated on a chip together with the at least one sensor, similar to an airbag sensor system. Such an integrated circuit can be mass-produced and installed in shoes or shoe inserts.
  • the evaluation circuit preferably comprises a processor with a memory that executes a program stored in the memory.
  • This program processes the signals received by the at least one sensor using an algorithm which uses the signals to determine typical features of the living being's locomotion.
  • the algorithm determines
  • Velocity and location vectors as typical features of the movement of the living being.

  • the senor can also be a capacitive monolithic silicon acceleration sensor.
  • the at least one sensor can have a transmitter for the wireless transmission of data by means of radio and / or infrared, in particular for the transmission of data to a receiver in an access control device.
