- the magnetic recording medium that can be used is not limited to a so-called magnetic card, but is intended to include any recording medium that magnetically records information and that requires so-called authentication.
- FIG. 1 is a schematic plan view showing a general magnetic card 10.
- the magnetic card 10 is provided with a magnetic recording area 12 to which a magnetic substance is directly applied or a film or the like to which a magnetic substance layer is applied is attached.
- three magnetic tracks 12a, 12b and 12c are formed.

If the magnetic card is used like a credit card from a credit card company at a bank, it will be read-only, and the basic information will include the owner's name, account number, credit card number, date of issue, etc. It is recorded in advance. -On the other hand, if the application of the magnetic card is a prepaid card, the cost information and the number of times of use are recorded as basic information, and these basic information can be rewritten after distribution of the card.
- FIG. 2 shows a physical pattern (corresponding to “second magnetic information” in the basic application) used for generating authentication information of each magnetic card according to the present invention.
- 3 shows a physical pattern forming unit according to the present embodiment for forming the magnetic recording area 12.
- a laser 14 is used as a physical pattern forming means, and a laser beam generated by the laser 14 is applied to the magnetic recording area 12 to form a physical pattern in the magnetic recording area 12.
- Laser; I4 is a rotary laser head, which irradiates a laser beam through a lens 16 to a magnetic recording area 12 of a card moving in a longitudinal direction.
- the rotation axis of the rotary laser head is arranged slightly inclined from the longitudinal direction of the card so that the irradiation area is perpendicular to the longitudinal direction of the moving card.
- Reference numeral 18 denotes a magnetic head that writes and reads basic information to and from a magnetic recording area.
- the magnetic head 18 is used to read magnetic characteristics based on the physical pattern formed in the magnetic recording area 12.
- one magnetic head 18 can perform not only writing and reading of basic information but also reading of magnetic characteristics based on a physical pattern. It is known that when a magnetic material is heated or heated above a certain temperature, its magnetic properties change or deteriorate. Therefore, when the laser is applied to the magnetic recording area 12 of the magnetic card 10, the temperature of that part instantaneously rises, and the magnetic properties of the part that has been irradiated with the laser are determined by the irradiation time, irradiation range, and irradiation light amount.
- the laser can easily control the traveling direction of the laser beam by mechanical control, so that the magnetic recording area 12 can be irradiated with the laser continuously or intermittently in any desired pattern.
- a pattern is called a “physical pattern”.
- a physical pattern By using a laser, a physical pattern can be formed quickly and easily, and the magnetic characteristics of the magnetic recording area 12 can be changed.
- a physical pattern should be formed so that the change in the magnetic characteristics due to the physical pattern does not affect the content of the basic information and the reading / writing of the basic information.
- a light beam having a high irradiation energy that can be a heat source, such as a halogen lamp can be used instead of a laser.

- FIG. 3B shows the magnetic recording area 1 in which the basic information is recorded as shown in FIG. 2 schematically shows an example of a state where a physical pattern is formed by irradiating a laser beam on the top of FIG.
- the vertical line in each area of the basic information (each area shown by S pole and N pole) is the physical pattern formed by laser irradiation.
- Territory One physical pattern is composed of the entire area. As described above, this physical pattern does not affect the basic information itself and the reading of the basic information.
- the existence of the physical pattern formed as shown in Fig. 3 (B) indicates that the existing basic information has been deleted and the basic information newly recorded That does not affect the.
- FIG. 4 is a diagram showing one track of the magnetic recording area 12 shown in FIG. 3B in more detail.
- the track width 22 for writing basic information to the magnetic recording area 12 by the magnetic head 18 and the track width 24 for reading the written basic information with the magnetic head 18 are, for example, 6 in the former case.
- the write track width 22 is wider than the read track width 24, such as 3 mm in mm and 3 mm in the latter. This is to ensure that the recorded basic information can be read even if the relative position of the magnetic head to the magnetic card slightly fluctuates in the vertical direction in Fig. 4 due to mechanical errors or the like when reading the basic information.
- the relative position of the magnetic head to the magnetic card slightly fluctuates in the vertical direction in Fig. 4 due to mechanical errors or the like when reading the basic information.
- the physical pattern is formed in a region completely included in the read track 24.
- the size of the physical pattern formation region 26 is set to 2 mm so that it is completely included in the read track width 24.
- the magnetic characteristics of the physical pattern forming region change before and after the physical pattern is formed.
- this change in the magnetic characteristics is a change at a minute level that does not affect the content of the basic information and the reading and writing of the basic information. Therefore, the magnetic characteristics obtained after forming a physical pattern are not only the physical pattern itself, but also the physical conditions around it, such as the size of each magnetic particle (number / xm ⁇ Several hundreds / m), shape, arrangement of magnetic particles, and magnetism based on basic information. In other words, the resulting magnetic properties are complex as they interact with each other.
- FIGS. 5 (A) and 5 (B) are block diagrams of an example of a circuit for processing signals obtained by reading magnetic characteristics from a magnetic recording area 12 where a physical pattern is formed by a magnetic head 18 (see FIG. 2). Is shown.
- the signal from the magnetic head 18 is amplified by an amplifier 30, passed through a high-pass filter 31, further amplified by an amplifier 32, and compared with a predetermined threshold by a comparator 33. Binary signals are output as a pulse signal.
- the signal from the magnetic head 18 is amplified by the amplifier circuit 40, digitally amplified by the AZD converter 41, and then digitally filtered and digitally encoded. 5 Outputs the same signal as the circuit in (A).
- FIG. 6 schematically shows signals in each part of the circuit in FIG. 5 (A).
- FIG. 6 (A) shows the signal waveform after amplification in the amplifier circuit 30.
- the signal waveform includes the shape and size of each magnetic particle constituting the magnetic recording area, the distribution of each magnetic particle, and the basic shape. Magnetism based on information is reflected. For this reason, all magnetic cards Even if the same physical pattern is formed, the signal waveform differs from card to card and is unique to the magnetic card.
- FIG. 6 (B) shows the signal after passing the signal of FIG. 6 (A) through the high-pass filter 31 and subtracting the DC component
- FIG. 6 (C) shows the signal after passing through the comparator 33 and performing digital filtering. Are shown.
- this series of numerical values is used as the authentication information of the magnetic card. That is, the value obtained here]: r 2 , r 3, ... is compared with the separately recorded authentication information, and it is determined whether or not they match with a certain range of error.
- the above-mentioned method of extracting authentication information is based on Fig. 6 (C) for some reason. It is possible to cope with a case where a part of the pulse of the signal waveform is missing. For example, if the above-mentioned authentication information is set to a certain number of numbers in series, for example, if more than 80% of them are in agreement, and if they match, a rule is recognized as an authentic magnetic card, then Even if a pulse of less than 2 °% of the signal in Fig. 6 (C) obtained from a simple magnetic card could not be read and was lost, it could be authenticated as an authentic card. On the other hand, a random force is inserted, and the probability that 80% or more of the authentication information extracted from it is accidentally matched is negligibly low. There is virtually no chance of recognition.
- a read-only card such as a credit card @ bank's cash card
- all issued cards can be individually specified by the authentication information obtained as described above. If this is used, for example, the following usage patterns can be considered.
- information identifying the owner name, account number, credit card number, etc.
- the supplier of the magnetic force records the basic information and authentication information of all magnetic cards on the server computer.
- the magnetic card reading device reads the authentication information in addition to the basic information.
- the readout device accesses the server computer via the communication line, and compares the read basic information and authentication information with the basic information and authentication information recorded on the computer. At that time, if the two match, the use of the card is determined to be proper use by the person.
- the basic information indicates that the card is used by the user, but if the authentication information does not match, it is determined that the card is used illegally.
- This may be the case, for example, when the basic information is read from one magnetic card and the basic information is copied on another magnetic card and forged.
- Such magnetic cards provide basic information Is the same as the original, but the physical information is not formed, or even if it is formed, it is different from the original physical pattern, so the read authentication information is different from the original. Therefore, in such a case, its use is immediately refused.
- a malicious user illegally obtains the basic information of another person's magnetic card, and it is possible to reliably prevent improper use when a forged magnetic card is impersonated and used based on this information. .
- the authentication information is recorded in a position different from the basic information of the magnetic card. Even if a malicious user illegally obtains the basic information and authentication information recorded on a certain magnetic card and forges the magnetic card based on this, even if the malicious user forges the magnetic card based on this, as shown in Figure 6 (A) obtained from the forged magnetic card. The signal waveform is different from the original magnetic card. Therefore, the authentication information extracted from the signal waveform of Fig. 6 (A) is compared with the authentication information of the original card recorded on the magnetic force, and if they do not match, it is immediately determined that the card is used improperly. be able to.
- the reading device itself checks whether or not the read authentication information matches the authentication and authentication information recorded on the magnetic card, the reading device of the magnetic card can be transferred to the server computer one by one. Access procedures can be omitted, and communication costs and communication time can be reduced.
- the pulse waveform of FIG. 6 (C) based on the signal waveform shown in FIG. 6 (A) and the authentication information based on this pulse waveform also change each time the basic information is rewritten.
- the pulse waveform shown in Fig. 6 (C) and the authentication information based on this are generated, and this is used as new authentication information each time. If it is recorded in a magnetic card, it can be handled in the same manner as a read-only magnetic card.
- the magnetic force of the present embodiment has a feature that compatibility with a conventional magnetic card reader / writer can be ensured.
- the physical pattern is recorded in the magnetic recording area 12 within a range that does not affect the basic information and its reading / writing. Therefore, the content of the basic information can be read from the magnetic card of the present embodiment using a conventional reading device. Further, basic information can be written on the magnetic card of the present embodiment on which a physical pattern is formed, using a conventional writing device. Authentication information cannot be handled by a conventional magnetic card reader / writer, but in that case, it can be used in the same range as before, and therefore, reading / writing of authentication information in the present embodiment is possible.
- a conventional magnetic card can be read / written / written for a conventional use by using a magnetic card reader / writer corresponding to the authentication information of the present embodiment.
- a physical pattern is formed by directly irradiating a magnetic recording area 12 with a laser with a magnetic force.
- the physical pattern of the present invention is not limited to such.
- Ferromagnetic materials are initially unmagnetized, but are magnetized when basic information is first written, and then retain this magnetized state.
- the magnetism caused by the ferromagnetic material is affected by the size, number, distribution, and interaction with the magnetism based on the basic information of the ferromagnetic powder. Become. If the signal waveform shown in Fig. 6 (A) is read from such a card, it is possible to extract authentication information unique to that card.

- an additive 50 that scatters or reflects light is mixed into the magnetic recording area 12 of the magnetic card, and a laser or other large heat is generated as a physical pattern forming means. Irradiates light (eg halogen lamp). Since the additive 50 distributed unevenly in the magnetic recording area randomly scatters or reflects the irradiated light, the physical pattern formed in the magnetic recording area 12 is based on the non-uniformity of the additive. It will be random. Therefore, the manner in which the physical pattern is formed differs for each magnetic card, and the obtained magnetic characteristics also change for each magnetic card.
- a surface coating material 52 mixed with a light absorbing substance 51 as an additive is applied on the magnetic recording area 12 of the magnetic card, and a laser is used as a physical pattern forming means. Or irradiate light with a large amount of heat (eg, a halogen lamp). Since the light-absorbing substance 51 distributed unevenly in the magnetic recording area randomly absorbs laser light and other light, the physical pattern formed in the magnetic recording area is also random according to the distribution of the light-absorbing substance. Become. Therefore, the physical pattern is formed differently for each magnetic card, and the obtained magnetic properties vary for each magnetic card. Become
- a heat ray reflective material is mixed as an additive when forming a magnetic force base material.
