Definitions
- This invention relates to a method according to the preamble of claim 1.
- Identification systems of this type are well known, for instance from US-patent 2 293 399.
- the objects to be identified by such systems may be of any kind, but they often are animals, for instance as described in US-patent 5 211 129. No specific means are disclosed in the patent specifications mentioned above for preventing or at least detecting fraud by copying transponders wherein the identification code of some valuable object such as an animal is stored.
- the transponders usually make use of integrated circuits (chips) as active elements.
- chips integrated circuits
- Fraud by copying the code of a specific transponder into an OTP or R/W transponder in order to obtain two identical transponders can occur and needs to be made impossible.
- One well known approach is to use a secret key and some cryptographic algorithm (symmetric or asymmetric) to generate a cyphrate out of a random number sent to the transponder as challenge. The cryphrate is sent back from the transponders to the reader. Often the code of the transponder is also used as input to the cryptographic algorithm. Knowing algorithm and secret key (or public key in asymmetric systems) the reader can authenticate the transponder at any time. This method, however needs to make use of at least one secret key which needs to reside within the transponder memory and therefore requires sophisticated key handling.
- EP-A-0 689 150 discloses a somewhat less sophisticated system, wherein a radio time signal received at reading time as well by the transponder as by the interrogating station. This time signal is combined with the identification code and retransmitted from the transponder to the interrogating station where the information retransmitted is analysed for reading the code.
- transponders are often passive elements without power source, the power for retransmission of the information being provided by the interrogating signal received by the transponder. It is impossible under these circumstances to continuously run a time clock in the transponder, and it is hardly possible to receive a radio time signal without power source in the transponder. Further, without cryptographic treatment of the time signal and code it would be possible for foreigners to determine the addition of a time signal and the code from the response signal of the transponder and thus to copy the transponder.
- This invention aims in providing security against copying without reaching the level of cryptography and without increased power requirement.
- This security is obtained by the characterising features of claim 1.
- the advantage of this method is that it is not requiring complicated and error prone key handling and requires almost no computing power. The latter in contrast to cryptographic methods.
- the method makes use of a chip serial number that makes the combination of the code and the chip serial number almost unique as long as the respective chip manufacturer never produces two identical serial numbers.
- a database can be used at identification set-up time when the code/serial number pair is stored into the database. At this moment, the database can be searched for double serial numbers and/or codes.
- a chip manufacturer identification may also be associated to the chip and made part of the serial number using the above method.
- checksum type information e.g. CRC
- CRC checksum type information
- This identification of the manufacturer or the user of the chip may be a trademark such as the registered trademark RID of applicant.
- a geographic information etc. can be stored into the database along with time and date of the read operation to facilitate plausibility checks.
- Other and additional information may be stored in the memory of the transponder. A possible method is described below, whereby additional information mentioned therein may be omitted or replaced by other specific information.
- the code, the die serial number, and the die manufacturer-ID are combined into a consistency check number using a specific method, e.g. a CRC scheme.
- the resulting number is programmed into the memory of the transponder, e.g. in the trailer bits and needs to be stored in the respective database or marked down in the animals passport, etc. for subsequent consistency check.
- the code, the die serial number, the die manufacturer-ID, and the consistency check number are read and the same method is applied to check consistency of all respective numbers. Then comparing the consistency check number (i.e. the number stored in the trailer bits) with the respective number in the database, in the animals passport, etc. the tag (transponder) can be authenticated.
- This method can prevent from copying transponders as long as no OTP dies are available that allow the programming of die serial number and die manufacturer-ID at code programming time.
- the first solution is based upon an information stored outside the transponder and the interrogating station, this information being not accessible during transmission of the response from the transponder, and said information being invariable and being used as a check basis (claim 2).
- the second solution is based onto a consistency test of two or more data stored within the transponder, these data being connected by an algorithm outside the transponder (claim 3). Therefore, no algorithm or key has to be stored in the transponder.
- the previous registration at identification set-up time may be compared to the information retrieved from the transponder at code-read time to discover fraud by modification of said information or fraud by copying the transponder using blank chips and copying the code leading to different serial numbers. This allows explicit authentification at any time.
- a checksum type information may additionally be stored in a database not accessible by fraudulent personnel.
- the method for generation of a checksum type information may be a hashing function calculated from any portion of the transponder memory.
- the method for the generation of the checksum type information may also be a cryptographic function calculated from any portion of the transponder memory and making use of symmetric or asymmetric keys and where only the results of the respective calculations are stored in the memory of the transponder but not said keys.
- it is of importance that no key has to be stored in the transponder.
- Another possibility is to store any additional information in the memory of the transponder in such a way that the boundaries of the individual numbers of the stored additional information are not distinguishable to the not knowing. In this way the boundary between the checksum type information and the remaining information shall be obliterated in order to protect the checksum type information from fraudulent analysis.
