Abstract

The invention includes a control system and a method for access control of an application system, with electrically measurable data acquired as the result of a biometric reaction of a user, the biometric reaction triggered by stimulatory information presented to the user. An acquisition means for acquiring the electrically measurable data, a provision means for providing reference data and a comparison means for comparing the data are provided in the control system. The reference data is provided relating to the stimulatory information and/or the acquired, electrically measurable data. The acquired measurable data is compared with the provided reference data by means of the comparison means. An authorization of the user to the application system takes place on the basis of the comparison results. By means of this control system it is possible to dynamically authorize and identify a user with absolute reliability and to unambiguously authenticate said user.

Claims

1. A control system for controlling access to an application system, comprising:

a presentation device for presenting stimulatory information to a user, wherein the stimulatory information is presented exclusively to the user who is to be authorized for an application system, and wherein no user information is assigned to the stimulatory information;

an acquisition device for acquiring current data comprising electrically measurable data as a result of a biometric reaction comprising a brain pattern of the user presented with the stimulatory information;

a storage device that assigns a unique authorization to the stimulatory information;

a comparison device that compares the acquired current data to provide a comparison result, wherein from a mental reaction of the user it is determined whether the user has recognized the stimulatory information,

wherein the biometric reaction of the user is triggered by a recollection of the presented stimulatory information, and

wherein, if the stimulatory information is known to the user, the user is directly authorized for the application system.

2. The control system as claimed in claim 1, further comprising a stimulatory information generating device that generates the stimulatory information.

3. The control system as claimed in claim 1, wherein the stimulatory information comprises one or more of an optical pattern, an acoustic pattern, or a combination thereof.

4. The control system as claimed in claim 1, wherein the stimulatory information is a group of patterns, comprising optical patterns, acoustic patterns, or a combination thereof.

5. The control system as claimed in claim 1, wherein the biometric reaction of the user is measured by electroencephalogram, electrooculogram or electromyogram.

6. The control system as claimed in claim 5, wherein, by means of an EEC reading (electroencephalogram reading), it can be deteimined whether terms, scenes or other things are known to the user.

7. A method for access control of an application system, comprising:

presenting stimulatory information to a user, wherein the presentation of the stimulatory information triggers a biometric reaction comprising a brain pattern of the user, wherein the stimulatory information is presented exclusively to the user who is to be authorized for an application system, and wherein no user information is assigned to the stimulatory information;

acquiring via an acquisition device current data comprising electrically measurable data of the user as a result of the biometric reaction;

assigning a unique authorization to the stimulatory information;

triggering the biometric reaction of the user by a recollection of the presented stimulatory information;

comparing the acquired current data to provide a comparison result, wherein from a mental reaction of the user it is determined whether the user has recognized the stimulatory information; and

authorizing the user directly for the application system if the stimulatory information is known to the user.

8. The method as claimed in claim 7, wherein the stimulatory information is provided as a group of patterns, comprising optical patterns, acoustic patterns, or a combination thereof.

9. The method as claimed in claim 7, wherein the biometric reaction of the user is measured via an electroencephalogram, an electrooculogram or an electromyogram.

10. The method as claimed in claim 9, wherein, by means of an EEC reading (electroencephalogram reading), it can be determined whether terms, scenes or other things are known to the user.
