Description

The invention relates to farm animal identification direction with a transponder chip, the transponder Chip is built into a support structure, which on a Farm animal is attached and the transponder chip egg has a storage sector, uses such Livestock identification device and a method to validate a product intended for slaughter res with such a livestock identification device. Farm animal means any of the human care, care or breeding subject. In addition to be slaughter agreed farm animals are therefore also pets, dairy cattle, Includes animals in zoos or wildlife parks, and the like!

For reasons of disease prevention and for the consumer It is desirable to have a surveillance system with protection Possibility of (possibly state) control of a farm animal to provide for This can ensure who that only meat from such farm animals has an end use reached user, whose origin and history define meets the criteria.

From the agricultural market reference 10/2001, pages 84-86, it is known to farm animals after birth with a benefit equip animal identification device which a Includes transponder. This farm animal identification device tion is attached to the ear of the farm animals. The transpon derchip stores important information in the course of livestock life  Data such as place of birth, parent animals or fattening farm. In a stall, slaughterhouse or cutting plant is u. a. on electronic reader for reading the transponder set up. All participating companies are online ver wets. When a farm animal is transported, the data flows as it were with and at a destination, one can Check by reading the transponder.

An RFID transponder chip without a carrier structure is out of the Literature DE 197 53 619 A1 known, which as Identification element u. a. for marking animals can be used.

From the literature US 4,461,807 is a farm animal identification device with a support structure and known transponder chip built into the carrier structure. A similar device is in the literature WO 93/22 907 A1.

From the reference DE 196 29 531 C2 is a Nutztie ridentification device known, in which the Spei only for security reasons against manipulation complete, but not partially deleted.

A disadvantage of the above prior art is that the manipulation possibilities in data technology Area not excluded with sufficient certainty are. In particular, there is no guarantee that people by storing incorrect data are closed.

The invention is therefore based on the technical problem to specify a farm animal identification device which against unauthorized storage of information, ins special incorrect information is secured.  

The invention teaches to solve this technical problem a livestock identification device with an RFID Transponder chip, with the RFID transponder chip in one Support structure is built in, which a farm animal arranges and / or is attached to it, and wherein the RFID Transponder chip has different memory sectors, which have different read / write permissions exhibit. A livestock identifier according to the invention tion device can be attached to a farm animal, but also, as it were, a farm animal pass separate from the farm animal managed and kept. Both together (if necessary with further farm animal passports at different places) redundancy acts, the risk of manipulation continues reduced.

RFID stands for "Radio Frequency Identification". own RFID transponder chips are for example Standard ISO / IEC 15693 removable. Of course but also different technical specifications possible. Examples of support structures are those of State of the art in question (injection molded parts), but also Plastic laminate structures in card form, in which the RFID transponder chip is laminated. Optimally are high-temperature plastics used for the support structure Turbo-resistant and biologically compatible and can tempe temperature loads of -40 ° C and + 100 ° C at 4 × 30 minutes / Survive 24 hours without damage. It goes without saying that if necessary with a suitable antenna structure connected to the RFID transponder chip and in the carrier structure is installed.  

The different read / write are preferably Authorizations using different keys for the different storage sectors. Here are the different keys, for example, according to one Key hierarchy established. This means that in the system different keys to use com men, where each key has separate access rights for different functions guaranteed. This allows separate users and those assigned to the respective user Access rights (read / write permissions) defined become. It is useful if the differ Chen read / write permissions for one or several authorized persons from the group consisting of "state regulators, veterinarians, breeders and masters ". The" Access authorization of a breeder or fattener is not that Include writing in memory sectors by one state regulatory agency and / or a veterinary ziners contain registered data. So it can Storage sectors based on access authorization be read-only with the key. insofar can write and / or read permissions correspond According to a hierarchical structure not only on one agreed to authorized group assigned own storage sectors, but according to the hierarchy also storage sectors of other group members with include. For example, it is possible that a Breeders and / or fatteners read / write permission only for has its own area. In contrast, can be provided be a state regulator and / or a Veterinarians do not have read / write permission owns only for its own storage sector, but also for the storage sectors of the others involved  authorized groups. Correspondingly, also limited ones Read permissions can be provided, for example a feed schedule with regard to quantities and times only for be readable by the breeder or fattener. The reading rights can be structured so that a complete Copy of the memory contents of a livestock identification establishment of no authorized group, at least ever if not by a breeder or fattener can be performed. A manipulation is then also inso far away.

The carrier structure preferably has an ear clip. This allows the usual attachment of the livestock identifi cation device on an ear of the farm animal. From green Protection against manipulation, it is advantageous if destruction of the support structure or opening of the Ear clips a deletion of memory content and / or a Setting a "manipulated" memory causes. This is in simplest case can be set up in that the carrier Structure is covered with micro lines, which me mechanical break become electrically high-resistance and thereby initiate the above processes. The ear clip, which one typically consists of two form-locking elements, can equipped with contacts on the positive locking elements be, in the closed state a low impedance Line loop is formed. When loosening the ear clip who which also opened the contacts so that the wire loop fe becomes high impedance. But it is also possible, for example Lich, a temperature sensor in the area of the ear clip and the above processes at subordinate / Initiate exceeding of defined temperatures. Corresponding programs are for the average specialist  easily within the scope of a controller of the RFID Trans ponderchips can be set up.

Furthermore, the invention teaches the use of an RFID Transponder chips for the production of a livestock identifier tion device, wherein the RFID transponder chip differs whose memory sectors are different from each other have different read / write permissions, whereby the RFID transponder chip built into a carrier structure and the carrier structure with the RFID transponder chip attached to a farm animal or associated with it, where defined before or after attachment / assignment Farm animal-specific data in at least one storage sec gate or in several memory sectors the. After attachment / assignment will be more appropriate gradually add further data in accordance with the different write permissions in different memory sectors are saved.

Finally, the invention relates to a method for vali a livestock intended for slaughter a livestock identification device according to the invention tion, data from the farm animal to a slaughterhouse are transmitted, whereby the delivered for slaughter Farm animal in the area of the slaughterhouse on a transpon the query device is guided past, whereby by means of the transponder interrogator data from the farm animal read identification device and with the transmitters telten data are compared, and according to the Comparing the data of the farm animal for slaughter leave or is rejected. A rejection in particular questioned if the data compared does not match come. A release can, for example, by the  Slaughterhouse or veterinary supervisor medical practitioners.

With the invention, overall due to the device of different storage sectors with differ Chen read / write permissions a high level of manipulation security achieved. A key can be used here Encryption of the data before it is saved in the Storage sectors are done. Using a reading system both a group identification and a Se individual identification can be carried out. Gruppenidentifi cation is the complete registration of all animals Group. Selective identification is the filtering out of one or several specific animals from the group, for example wise based on the ID numbers. Overall, you can be lively for animal breeding, consumer protection and Make animal welfare easier and especially one monitor more often. A livestock identifier according to the invention cationseinrichtung can be used as a seal of livestock be used. An external attachment of a he livestock identification device according to the invention to an egg The advantage of a farm animal is that the consumer can Implan showing little acceptance actions are not necessary. Basically, self-ver the use of a farm animal according to the invention not in the context of implants locked out. Within the scope of the invention, a trust can ter, which central data of all users animals recorded, managed and monitored. To one Trust centers are all connected from the birth of one Places involved in livestock until slaughter. Manipulations can be made in the data network by rapid comparison of target / actual are determined. This double  Data storage (software or database or trustcen ter / animal or animal passport) is particularly advantageous way. On top of that, in case of database problems nevertheless the data are available, namely based on the Livestock identification device.

Readings are made especially before slaughter the data from a farm animal identification device and their comparison with those for the farm animal in question Trust center stored data. Within the scope of the invention it is also possible that transport times are recorded. here at is by a transponder interrogation device first station a first time stamp in a memory sector registered and after completion of the transport there is a corresponding storage or lock a second time stamp at a target station. By reading out and forming the difference between the first and second timestamp can thus also legal trans port times, especially between breeder and slaughterhouse, be checked and monitored. Conclusions too Transport routes (and detours) are possible, which in particular may be relevant for truck / highway transport.

In the following, the invention is based on only Aus figures illustrating leadership examples.

It shows:

In Fig. 1, a livestock identification device 1 according to the invention is shown. It has a card-shaped support structure 2 (format: e.g. identity card), which is laminated from several polymer layers. Any other shapes and formats are of course also possible. A printed (paper) layer can be laminated. In any case, an RFID transponder chip with associated antenna is laminated. Data can be stored in and read from the transponder chip, as described later. In addition to the examples mentioned in Table 1, the data can also include DNA / R NA data and / or other biochemical "fingerprints" or characteristics of an individual. Blood analysis data, for example drug levels, are also particularly suitable here. The polymer layers of the support structure are temperature-resistant from -40 ° C to over 100 ° C. The support structure 2 has a form fit 5 , in which a polymer rivet can be riveted. When attached to a farm animal, the polymer rivet passes through an ear of the farm animal and thus holds the carrier structure to the farm animal. Data in plain text and / or encrypted form can be attached to the printed (paper) layer. The carrier structure can further contain security and / or verification elements known from security document technology, for example a hologram.

In FIG. 2, the basic structure is one within the framework of the invention men my-d Transpon derchips 3 shown preferably used. One can first see an antenna NEN connection 7 , to which an antenna 4 is connected. Connected to the antenna connector 7 is a control unit 8 which, among other things, controls an access control 9 and a memory access 10 to the memory 11 with the various memory sectors. Within the framework of the memory 11 , secured memory sectors 17-19 (see FIG. 4) with variable data access are released for several users or for their read / write devices 12 if these have the appropriate access rights. RFID transponder chips 3 used according to the invention operate for example with a standardized working frequency of 13.56 MHz and have up to 10 Kbit and more of available memory 11 .

In FIG. 3, it detects a present invention is translated RFID transponder chip 3, which is addressed by means of a read / write device 12th This has an antenna 13 , a control 14 therefor, and a microcontroller 15 . The microcontroller 15 can optionally be connected to a computer system 16 . Not only the data transmission takes place at the working frequency, but also the required energy transmission to the transponder chip 3 is carried out with this working frequency. Read / write operations take place in milliseconds rich, so that reliable data transmission is guaranteed even with fast moving farm animals.

In FIG. 4 one recognizes the organization of a memory used in the invention the RFID transponder chip 3. A total of three memory sectors 17-19 can be seen in the figure, to which different keys 20-22 are assigned. By means of the keys 20-22 an access authorization, in particular a write and / or read authorization for the assigned memory sectors 17-19 is defined and / or an encryption of the data stored in the assigned memory sector 17-19 is set up. Specifically, the key 20-22 for encrypting the data of the associated memory sector ( 17-19 ) can encrypt the data stored or stored therein. The access authorization is then defined in that a reader (with which it may also be possible to write into the transponder) either has the key assigned to the access authorization stored, or an operator must first enter the key therein, similar to a PIN.

For example, the following Table 1 shows access authorization of different groups of people to different memory sectors or memory contents shown.
