Recognition system for searching and recognizing data patterns and identification system for storing and recognizing data patterns

The present invention relates to a recognition system of the type specified in claim 1, which is used for searching and recognizing those data patterns which substantially match a predetermined data pattern, and to an identification system of the type specified in claim 21, for identifying a person in order to do so to give authorization at certain points.

The most reliable detection of matching or at least essentially matching data patterns is a common problem that occurs in many variations in daily life and is often still largely unsolved. A data pattern in the sense of the invention can e.g. a compilation of the essential preferred properties of a desired partner, e.g. an indication of body size, hair color or hobbies that you would prefer to expect from a partner. A data pattern in the sense of the invention can, however, also be information or information that a person is looking for in a particular situation or environment; For example, it is often very difficult at a trade fair to focus specifically on those exhibition stands that may show the products that are of interest to the person concerned.

In the first-mentioned problem of recognizing the ideal

Data pattern of a desired partner, the main difficulty is that on the one hand, many of the searched for

Characteristics are not obvious when you have one meets another person, while on the other hand it is usually impossible or at least takes some effort to address all those people and ask about their characteristics that at first glance seem sympathetic to you. The partner search is therefore carried out in particular through advertisements or with the help of special institutes.

In the second-mentioned problem of recognizing all of the trade fair stands that may be of interest, the difficulty lies in the fact that it is usually not easy to find the relevant information from the abundance of incoming optical and acoustic information in a reasonable time.

The invention is therefore based on the object of providing a recognition and identification system of the type specified in claim 1 or claim 21, which enables a very simple and expedient type of recognition of matching data patterns and in particular, if not exclusively, for the above problem cases is suitable.

This object is achieved according to the invention with the features specified in claim 1.

The invention thus proposes a recognition system which contains at least a first and at least a second electronic device, at least the first device being portable and a display device, a storage device in which the respectively predefined data pattern can be stored, and a wireless transmission and Has a receiving device which transmits the predefined data pattern and actuates the display device when a match signal is received; the second electronic device also contains a memory direction in which a further data pattern can be stored, and a wireless transmission and reception device; furthermore, this device has a comparison device which, upon receipt of the predetermined data pattern sent by the first device, compares it with the further data pattern and triggers the transmission of the match signal when both data patterns match to a predetermined degree. The degree of correspondence can be set continuously between 0 and 100%.

If both the first and the second electronic device are constructed identically, i.e. if both devices are portable units, each having a display device, a memory device in which, in addition to the specified data pattern, a data pattern representative of the device in question can also be stored, a transmitting and receiving device and also a comparison device, so that the detection matching data pattern is mutually possible, the recognition system according to the invention is particularly suitable for carrying out a new type of partner search:

It is possible, for example, to distribute devices according to the invention to all persons willing to do so within discos or nightclubs, during animations or club holidays, in retirement homes, at television shows or promotional campaigns and at other major events. Then when each of these people - for example by means of a computer by keyboard or touchscreen input or with the help of a data reader into which a filled-in card can be inserted - enters the respective data pattern of their desired partner (i.e. information about body size, hair color, hobbies etc. ), the display device always becomes a match display if a desired partner is within the transmission and reception range. You can thus easily identify a potential partner of choice and generally have no inhibitions about contacting this person now.

With this type of partner search, it is also advantageous if the first device compares the data pattern sent by the second device with the representative data pattern stored in it, while the second device compares the data pattern sent by the first device with the representative data pattern stored in it , and each device should only generate a match indicator if it has both sent and received a match signal. This ensures that only those pairs can be found that really match.

Since in practice it will often not be possible to find a sufficient number of people whose search pattern is in complete agreement, it will generally be expedient to determine the degree of agreement of the search pattern to be compared that is used to generate the match signal leads to make changeable, whereby it will be advantageous at the mentioned events to set the degree of agreement for all devices used together to the same value.

However, the detection system according to the invention is also suitable for searching for information at trade fairs or similar events: in this case, each visitor using the system carries an electronic device of the first type specified in claim 1, while each trade fair stand has a (possibly stationary) device as claimed in claim 1 specified second type. As soon as the user has entered the data pattern (again using a computer or a data reader) that corresponds to the information or trade fair novelty he is looking for, his device will always provide a match indicator when he is in the vicinity of a trade fair stand that is suitable for is interesting to him. The information search is thus made considerably easier.

In this case too, it can be advantageous if the degree of correspondence can be changed, it being advantageous here if the user of the respective device can do this himself (and possibly on the device).

The portable electronic devices of the recognition system according to the invention are preferably designed as attachable or transferable buttons and preferably work with infrared rays of a predetermined range. To avoid disruptive interference or to reduce data traffic, it is advantageous if each transmitter device first sends out a specific code and then sends out the specified data pattern or the match signal only when the associated receiver device receives a corresponding confirmation code from another device .

The first or second electronic device is supplied with power in a simple manner via a battery or a rechargeable energy store, such as an accumulator or a capacitor, it being possible for the rechargeable energy store to be charged with electricity from solar cells.

If the first or second electronic device of the recognition system according to the invention has an input direction, the respective data pattern can be entered into the electronic device in a simple manner. For this purpose, the data pattern is entered directly into the electronic device, for example using a keyboard, which then stores it in its memory device.

By providing the first or second electronic device of the detection system according to the invention with a function status display device which determines and displays the function status of the electronic device, it is possible to inform the user about the state of charge of batteries or accumulators in the electronic device or about the functionality of the electronic device Device.

The detection system according to the invention furthermore has at least one further wireless transmitting or transmitting and receiving device, which transmits or communicates further data to the wireless transmitting and receiving device of at least one electronic device to be determined. The further transmitting or transmitting and receiving device, which is connected to a central location, preferably works with infrared rays of a predetermined range and is designed such that it transmits data from a central location to one or more electronic devices located within the predetermined range or vice versa. The data can, for example, in the direction of transmission to the electronic device for a gain of the user of the electronic device in a game carried out simultaneously and in the direction of transmission in the further transmission and reception direction to the presence of the electronic device and thus the user within the predetermined range for the further Transmit and receive device around concern. So that the transmission data can take place, either the transmitting or transmitting and receiving device must send the electronic device or vice versa a predefined data pattern (or a specific code) which is linked to the data pattern stored in the further sending or transmitting and receiving device and the electronic device ( or code) must match. Corresponding comparison devices are provided in the transmitting or transmitting and receiving device and / or the electronic device.

The display device optically and / or acoustically displays the further data received from the further wireless transmitting or transmitting and receiving device.

A control device controls the functions or the functional sequence of the first or second electronic device by means of a control program which is stored in a further memory device. This memory device is preferably designed as an EEPROM. The memory content of the memory device can be changed by externally supplied signals, so that the electronic device can be reprogrammed with regard to the functions or the functional sequence. This increases the possibility of using the electronic device.

The control or correspondence device of the first or second electronic device determines the degree of correspondence and / or non-correspondence of the respective data pattern and supplies a corresponding signal to the display device for displaying the determined degree.

The display device of the first or second electronic device is provided with an interface for further processing of optically and / or acoustically. connectable signals. For example, the display device can be held to the receiver of a telephone system, so that the data relating to the degree of correspondence and / or non-correspondence between the respective data patterns is forwarded from the display device to a central unit and evaluated there.

Since the transmitting and receiving devices of the electronic devices and the further wireless transmitting or transmitting and receiving device work with infrared rays of a predetermined range, the communication is restricted to a predetermined range.

Personal identification is of crucial importance in security systems of, for example, companies or research institutions. Personal identification is intended to prevent unauthorized persons from gaining access to security-relevant areas. Personal identification also plays an important role at large events, such as trade fairs, congresses or political rallies, where it is used, among other things, to protect people. Important or dangerous objects can also be considered for an identification system under the security aspect.

Known identification systems use small plastic cards with a magnetic strip on which the identification data, such as name, date of birth, passwords, etc., of the person concerned are stored. The secure and reliable recognition or recognition of people is not easily possible simply by identifying the personal data, since, for example, the plastic cards could be exchanged or shared. To prevent such abuse, there is therefore a need for an additional one visual recognition possibility. As a result, in some identification systems an additional passport photo of the person concerned is attached to the card.

If the plastic card with passport photo is reasonably forgery-proof, the passport photo must be attached to the plastic card in a manner that is difficult to replace. For example, the plastic card and passport photo are sealed in foils. Falsification by exchanging the passport photo is then no longer possible without considerable effort. However, a desired exchange, for example due to heavy soiling of the surface of the plastic card, a major change in the appearance of the person concerned (e.g. shaving a full beard or severe weight loss), is then made more difficult. This means that updating the image data of people involves considerable effort, but the security against forgery of such cards is comparatively low. This also explains the fact that card systems of this type are generally not recycled. After a large event, such as a party convention or congress, which does not take place regularly with the same participation, all cards are destroyed. This is both an economic and an ecological disadvantage of the magnetic card system.

Another disadvantage is that cards with a magnetic memory device, such as a magnetic stripe, cannot be read or written over long distances without additional devices. It is therefore not possible to transmit data to the card or the magnetic stripe by means of wireless transmission, for example by infrared transmission. Authorization, which is stored as a code on the card, cannot be issued using wireless transmission. In such systems are used for reading or writing the magnetic strip mostly uses magnetic readers and writers that have a slot through which the card must be pulled in a certain orientation. This movement sequence must therefore be carried out by each person to be identified during identification. In addition, signs of wear will appear on the types of plastic over time, which can also prevent the passport photo from being clearly identified.

Another disadvantage is that the visual information of the passport photo cannot be used directly in a data processing system, such as a computer, since this requires prior digitization of the analog image information present in the form of the passport photo.

It would therefore be advantageous to create an identification system in the manner specified in claim 21 which has improved identification of persons, increased security against forgery and improved manageability, and in particular, if not exclusively, avoids the disadvantages mentioned above.

The electronic storage of the image data of the person offers the advantage on the one hand that the image quality is largely protected from environmental influences, and on the other hand the advantage that renewing the image information with the aid of the recording device is easier compared to the creation of a new passport photo and subsequent attachment to the plastic card and can be carried out faster. When using a wireless transmission of data patterns and codes, this is also done without wear and does not require any particular movement sequences from a person to be identified. Consequently handling of the system compared to the card system is also simplified, and thus improved. With electronic storage, daily updating of the image data is therefore also easy to carry out, as a result of which the image data of the person are always up to date.

In addition, electronic storage offers significantly more protection against counterfeiting, especially if the data patterns are encoded (i.e. encrypted). Even without such additional coding, the manipulation of electronically stored data in the electronic device requires significant technical knowledge and understanding.

In the identification system according to the invention, the result of the identification can be recorded by, for example, infrared transmission of a release code in the electronic device to be carried (also referred to below as an ID button). This offers additional protection against forgery or misuse of the authorization or access authorization. In addition, an individual authorization can be carried out for every person, which also leads to an increase in the counterfeit security of the system. One could, for example, grant access authorization that is limited in time and / or space.

In an identification system of the type according to the invention, the image information contained in the data patterns offers an advantage when logging identification processes. If it is found at a later point in time that an ID button has been forged or misused, at least the appearance of the perpetrator is known. In addition, if a release code is used, this can also provide information about make any affected areas. This makes prosecution easier and has a certain deterrent effect on potential perpetrators. This also improves the security of the system.

In order not only to be able to capture image data already provided in digitized form, for example on a floppy disk, in the capture device, the capture device provides an optical recording device for recording the analog image data of a person.

If digital photo cameras or digital video cameras are used as optical recording devices, digitization by the processing device can advantageously be dispensed with, since these already supply the image data in digital form.

Another embodiment includes an ID button on which a hard copy of the stored data pattern is visibly attached. This enables limited identification in the event of a system failure.

A further embodiment includes an ID button, the storage device of which uses an EEPROM memory, and is therefore independent of a voltage supply or energy supply with regard to maintaining a memory content.

A further embodiment uses an accumulator for the energy supply of the devices of the ID button, as well as solar cells for charging the accumulator. Instead of the accumulator and the charging device, a battery can also be used. An advantageous embodiment in which the comparison result is displayed optically and / or acoustically is also conceivable.

The portable electronic devices of the identification system according to the invention are preferably designed as attachable or transferable buttons and preferably work with infrared rays of a predetermined range. To avoid disruptive interference or to reduce data traffic, it is advantageous if each transmitting device first transmits a specific code and then only transmits the specified data pattern or the match signal when the associated receiving device receives a corresponding confirmation code from another device .

If the portable electronic device of the identification system according to the invention has an input device, the respective data pattern can be entered into the portable electronic device in a simple manner. For this purpose, the data pattern is entered, for example by a keyboard, directly into the portable electronic device, which it then stores in its storage device.

By providing the portable electronic device of the identification system according to the invention with a functional status display device which determines and displays the functional status of the portable electronic device, it is possible to inform the user about the state of charge of batteries or rechargeable batteries in the portable electronic device or about the functional of the portable electronic device. The identification system according to the invention furthermore has at least one further wireless transmitting or transmitting and receiving device, which transmits or communicates further data to the wireless transmitting and receiving device of at least one portable electronic device to be determined. The further transmitting or transmitting and receiving device, which is connected to a central point, preferably works with infrared rays of a predetermined range and is designed such that it transmits data from a central point to one or more portable electronic devices located within the predetermined range, or vice versa. The data can, for example, in the direction of transmission to the portable electronic device for a gain of the user of the portable electronic device in a game carried out simultaneously and in the direction of transmission in the further transmission and reception direction to the presence of the portable electronic device and thus the user within the concern predetermined range around the further transmitting and receiving device. In order for the data to be transmitted, either the transmitting or transmitting and receiving device must send the portable electronic device, or vice versa, a predetermined data pattern (or a specific code) which is associated with that in the further transmitting or transmitting and receiving device and the portable electronic device stored data pattern (or code) must match. Corresponding comparison devices are provided in the transmitting or transmitting and receiving device and / or the portable electronic device.

The display device optically and / or acoustically displays the further data received from the further wireless transmitting or transmitting and receiving device. Since the interfaces of the detection device, the electronic device, the control device and the further wireless transmitting or transmitting and receiving device of the identification system according to the invention work with infrared rays that can be used within a predetermined range, the communication is limited to a predetermined range.

Further advantageous developments of the invention are the subject of the dependent claims.

The invention is explained below with reference to the description of exemplary embodiments with reference to the drawing. Show it:

The detection system described below relates to an embodiment of the invention which is suitable for carrying out the novel type of partner search described at the outset. Accordingly, this system consists of a variety of portable electrical devices in the form of buttons (see Fig.l), an input device for entering the search pattern in the form of a computer (see Fig.2) or a data reader (see Fig.3).

According to FIG. 1, each button B according to the invention consists of a housing which is sufficiently small to be able to be plugged in or transferred around without problems. Inside the button B there is a battery (not shown) for the power supply, a storage device (also not shown) in which a predefined data pattern (which corresponds to the search profile of the desired partner) and a representative data pattern (which corresponds to the property profile of the person wearing the button contains) can be stored, as well as a (also not shown) wireless transmitter and receiver, which works in the example with infrared rays that have a range between 1 and 5 meters. Furthermore, the housing of the button B contains an electronic control unit, which in particular has circuits for controlling the storage device and the transmitting and receiving device, and a comparison device.

A display device A, an operating display BA, a display for special functions SA and an advertising space W are provided on the outside of the housing of the button B. The display device A has a plurality of light-emitting diodes LED, which form a heart-shaped figure which surrounds an inner cross; if the heart shaped Figure (possibly flashing or with a running effect), a match is displayed, while driving the cross indicates a mismatch. The operating display BA also consists of light-emitting diodes and can optionally be an LED running light. The special function displays SA are used to display the results of competitions or promotions. The advertising space W can finally be used for advertising purposes by sponsors and bears corresponding logos.

Either the computer PC shown in FIG. 2 or the data reader DL shown in FIG. 3 will be used to enter the data into the respective button. In the case of the computer PC, the data is input either with a keyboard or by touching the corresponding screen areas (touchscreen input). When using the data reader DL, on the other hand, corresponding cards are filled in by the respective person and inserted into a slot in the data reader DL so that the data on the card can be scanned. In both cases, the recorded data is transmitted wirelessly to the button B located nearby and stored in its storage device, as is symbolically indicated in FIG.

4 shows an embodiment of a card BK which can be inserted into the slot of the data reader DL. This card DK also shows the data pattern according to the invention which, in the case of the partner search game described here, contains data about the desired partner, namely information about the area of the desired age, body size, hobbies, etc.

According to a further embodiment, the button B has an input device (not shown in the figures). A button control device activates a corresponding sequence program which leads a dialog with the user of the button via the display device A. The respective input of the data requested via the display device, which together form the predetermined data pattern M, is carried out using a keyboard. The data entered in each case is stored in the storage device of the button immediately after it has been entered, or is only temporarily stored and then stored overall in the storage device of the button.

The button B is provided with a function status display device (not shown in the figures) which determines and displays the function status of the portable electronic device. The user of the button is informed by the function display device about the state of charge of batteries or accumulators located in the button and about the functionality of the button as a whole. For this purpose, the control device of the button is provided with the test devices necessary for recording the functional status of the button.

The partner search game runs with the recognition system according to the invention according to FIG. 5 as follows:

Each player receives a button B and uses it to go to the nearest computer PC or to the corresponding data reader DL. With the help of the computer PC or by filling out a corresponding card DK, the player specifies both his own data pattern (ie the "representative" data pattern of his button) and the data pattern of his desired partner (ie the "specified" data pattern of his button). Both data records are transmitted wirelessly to button B after entering a corresponding command on the computer PC or after inserting the cards DK into the data reader DL and stored in its storage device. Then this button begins to send a code signal continuously or at cyclical intervals.

If the relevant player (for example the man designated 4 'in FIG. 5) is within range of another player (eg within the range of the three women 1 ^' to 3 ^" shown in FIG. 5), the buttons B are these four players capable of receiving the code signal of the other button. After receiving the code signal, each button B sends out the "predetermined" data pattern stored in it, ie the desired search pattern. This is received by the other button and with the "representative" stored there "Data pattern compared, that is, the property profile of the wearer of the button in question. In the event of a match (or a certain degree of match), the button sends a match signal that is received by the transmitter of the search pattern data. Each button that sends both a match signal as receives one, then activates its match display; for example, contain n the button of the woman 2 ^' and the button of the man 4 ^' each have data patterns that mutually correspond to the ideas of the two people, so that the display device activates the heart-shaped LEDs flashing: the two people 2 ^' and 4 ^' therefore recognize that they are each other's desired partner.

In contrast, for the two women 1 ^' and 3 ^' , the buttons activate the cross-shaped display to indicate that there is no match.

The respective degree of correspondence is preferably specified uniformly by the organizer for all buttons used. By changing this grade you can thus influence can be exerted on the number of pairs finding each other.

If the recognition system according to the invention is used for measurements, the described process proceeds in principle in a similar manner, but the recognition display of the button is already activated when a match signal is received, since in this application of the invention no mutual match is required, as is the case this is the case with a partner search game.

Furthermore, the detection system according to the invention is suitable for forwarding information from a central point via one or more further wireless transmitting or transmitting and receiving devices to the respective portable electronic devices or vice versa. For example, the current location of the user of a portable electronic device can be determined centrally and any information that is displayed optically or acoustically on the display of the portable electronic device can be transmitted to him.

The identification system (1) described below relates to a preferred embodiment of the invention.

The identification system (1) accordingly consists of a detection device (see FIG. 6), one or more ID buttons (see FIG. 8) and one or more authorization points (see FIG. 7).

The detection device (4) in FIG. 6 consists of an optical recording device (43) and a com- computers (41) connected to each other. The computer (41) also has, as an interface to an electronic device (ID button) (3) to be carried, a wireless transmission device (42) which in this exemplary embodiment works with infrared transmission. The optical recording device (43) serves to record the image data of a person (2) and transmits the recorded image data to the computer (41). The computer (41) digitizes the image data, if necessary, and, together with the characteristic data of the person (2) entered or already stored via a keyboard (not shown) (eg age, name, identification numbers, secret codes, etc.), forms a person-specific data pattern for the person (2). The wireless transmission device (42) sends the person-specific data pattern to the ID button (3), which stores this in its storage device (not shown).

An ID button of this embodiment is shown in FIG. 8. The ID button (3) is able to save and send digitized image and text information. It has a storage device (not shown) for storing person-specific data patterns. It also contains a wireless transmitter (31) and a wireless receiver (32), which also use infrared transmission. The dimensions of the housing of the ID button (3) (approx .: 40x70x10 mm) are so small that it can be attached to a jacket or shirt, for example. The ID button (3) is operated by a battery (not shown). In this embodiment, the ID button (3) has an LED display (34) on the outside with the inscription "ON / OFF", which indicates the operating status of the ID button (3). If the ID button (3) is in operation, the LED display lights up, if the ID button (3) is switched off or the battery is empty, it does not light up. A control device (5) of an authorization point of this exemplary embodiment is shown in FIG. 8 and consists of a computer (52) with a monitor (521) and an optical recording device (53). The computer (52) also has a transmitting device and a receiving device (both not shown), which also work with the wireless transmission of infrared rays.

An identification process of the system of this embodiment is described below:

If a person comes to an authorization point for identification, the ID button (3) sends the person-specific data pattern, which contains the identification data and the picture of the person, to the computer (52) of the authorization point. This receives the image and stores it in the working memory (not shown). In addition, the optical recording device (53) takes a picture of the person at the authorization point. This image is also fed to the computer (52). This digitizes it if necessary and carries out an image pattern comparison. This means that he compares the image data of the data pattern received by the ID button (3) with the actual appearance of the person at the authorization point. If the two images largely match, the computer (52) determines that the person has been correctly recognized visually. At the same time, the computer (52) compares the person-specific identification data received with the identification data stored in a database (not shown). If these also match, the computer (52) determines that, when the visual recognition described above is present, a release code for authorization by the wireless transmitter is sent to the ID button. At the same time, the image of the person is displayed on the monitor, so that a person has the Can track comparison process. The release code is stored in the storage device of the ID button and can be queried electronically for further identification processes. The person-specific data pattern received by the ID button and the release code are stored in a database by the computer (52) and are used for logging the identification process. The identification process is now complete.

As the above description shows, multiple modifications or variations of the illustrated embodiment are possible without leaving the scope of the invention.

For example, the degree of correspondence of the image data can be adjustable in the embodiment described above. Likewise, a control person can assess the correspondence of the image and characteristic data instead of the comparison device on the basis of the display of the monitor and decide on the granting of an access authorization.

Furthermore, the identification system according to the invention is suitable for forwarding information from a central point via one or more further wireless transmitting or transmitting and receiving devices to the electronic device or vice versa. For example, the current location of the user of the electronic device can be determined centrally, and any information that is displayed optically or acoustically on the display of the electronic device can be transmitted to him.
