Description

  The present invention relates to an authentication system that is useful when applied to various electronic devices such as watches.

  Conventionally, a data carrier system (or Radio Frequency IDentification system = RF-ID system (ISO / IEC 14443) is a system that can read or write data from an information carrier in a non-contact manner by electromagnetic induction waves without directly passing a reader / writer. ), Hereinafter referred to as an RF-ID system).

  Today, the RF-ID system uses an IC card as an authentication medium (data carrier, ID Tag, hereinafter referred to as ID-Tag), an electronic ticket, an electronic ticket, or an electronic lift ticket used in a ski resort. Etc. are used.

  For example, in an electronic lift ticket, the ID tag corresponding to the RF-ID system is incorporated into a bracelet, necklace, or wristwatch worn by a skier (person to be authenticated), and the skier is provided at the entrance of the lift. You can pass through this gate by holding it over the reader / writer of the gate. This improves the ease of use of the lift for skiers who are busy with stock.

  Further, various communication methods of the RF-ID system are used depending on the application. For example, in the case of an electromagnetic induction system in an RF-ID system, the ID Tag is composed of an antenna coil formed with a loop and a data carrier IC that controls the induced electromotive force of the antenna coil, and a reader / writer provided at the gate. The antenna coil or the antenna coil with a magnet core is opposed to the antenna to communicate a signal of 100 to several hundred KHz (long wave to medium wave) as an information transmission medium using an induction electromagnetic field. .

  According to the above communication method, the ID Tag receives data by the coil antenna at a distance of several tens of centimeters, and reads / writes data in the nonvolatile memory in the data carrier IC.

  And long wave to medium wave signal used in such electromagnetic induction method, or electromagnetic coupling method that can transmit power at the same time without transmitting a battery, easily penetrates non-conductive materials, It is difficult to receive the reflection of the conductor, and in addition, since the directivity of the electromagnetic wave is low, there is an advantage that the communication data is not easily changed even if the direction in which the ID tag passes at the time of communication is slightly changed. If the constructed obstacle is between the gate and the gate, an electromotive force is generated in the metal by the magnetic field from the antenna coil to induce an electric current, and the electric field is disturbed by the electric current to cause an obstacle that prevents communication.

For this reason, the ID Tag used in the electromagnetic induction type or electromagnetic coupling type RF-ID system is incorporated into a bracelet, necklace or watch worn by a skier (authenticated person) and used as an electronic lift ticket. If you want to
(1) A structure in which the ID Tag is attached to a resin wrist band or arm band. (2) A structure in which a square type or coin type case with a built-in ID tag is attached to a wristwatch type holder.
(3) A structure in which the loop antenna coil of ID Tag and the data carrier IC are housed in a resin watch case and a back cover.
By adopting such a structure, the above problem is overcome and a good communication environment is secured.

  However, even if the above structures (1) to (3) are adopted, in the case of a wristwatch in which the decorative value as an accessory, the value as a fashion, and the value as a jewelry precious metal are emphasized, the ID Tag is arranged. There has been a problem that the value of the manufacturer has been significantly reduced, and the manufacturer cannot flexibly respond to the taste and use of the customer group in the design etc. when designing the watch. As the most general method for solving such a problem, there is a method of making the ID Tag difficult to see from the outside by incorporating or integrating a non-contact type electronic path into a main body such as a wristwatch.

  However, if it is simply built-in or integrated, especially in the case of outdoor and sports watches, for example, it is placed on the watch body for the purpose of improving waterproofness (pressure resistance), impact resistance, robustness, and environmental resistance. Since many metal members (conductors) are used for the back cover, window frame, etc., there is a problem that data communication with the reader / writer installed at the gate is likely to fail. Arise.

  And in order to avoid the above obstacles, such metal members must be replaced with non-conductive members such as resin, so the manufacturer has the waterproofness (pressure resistance), impact resistance, and robustness of the watch body. There is a problem that it is impossible to guarantee the performance and the environmental resistance.

  In addition, today's RF-ID systems are mostly applied to electronic periodic systems and prepaid card systems. However, contact protection is required for data protection, especially for credit systems and electronic commerce that involve security issues. Development is delayed from the IC card system.

  The present invention has been made in view of such conventional problems, and an object of the present invention is to provide an authentication system aiming at improvement in use by a user who receives a system service, taking into consideration the reliability of security problems.

And an information display means for displaying.

  According to a fourth aspect of the present invention, there is provided an authentication system in which the electronic device stores data communication means for performing data communication via a public line network and data communicated by the data communication means. And a first control unit for extracting data used in the authentication system from the data stored in the second storage unit and controlling the electronic device based on the data. It is characterized by.

  In the authentication system according to the fifth aspect of the present invention, the electronic device further includes communication control means for performing data communication of authentication data stored in the electronic device by the data communication means. Features.

  Further, in the authentication system according to the invention of claim 6, the first management means for managing the deposit account of the person to be authenticated, and the contents of the charge due to the use of the authentication system by the person to be authenticated When the use of the authentication target person to the system by the matching of the authentication data is permitted by the second management means to be managed and the authorization means, the first management means and the second And a second control means for controlling the management content of the management means.

  In the authentication system according to the seventh aspect of the present invention, a first connection unit that connects the permission unit, the first management unit, and the second management unit via a network is provided. And further comprising.

  The authentication system according to claim 8 further includes second connection means for connecting to a storage management system existing outside the authentication system via a network.

  The permission means includes an access permission means for permitting access to the storage management system via the second connection means when use of the authentication system is permitted due to a match of authentication data. .

  According to the authentication system of the present invention, authentication data is read from an electronic device attached to the person to be authenticated in a non-contact state by electromagnetic induction, and the authentication data matches the authentication data registered in the system. In this case, since the use of the system of the person to be authenticated is permitted, the use of the system can be managed without making the user feel complicated.

  In addition, since the usage status of the system is read and displayed from the card-shaped storage medium owned by the person to be authenticated by electromagnetic induction, the user should carry the card-shaped storage medium in a pocket of clothes, etc. Thus, the usage status of the system can be easily confirmed.

  In addition, since the electronic device transmits data that is permitted to be transmitted due to a match of authentication data, the authentication system receives the data and displays information based on the received data. When they match, a message or the like can be displayed on the information display means on the authentication system side so that the person to be authenticated can visually recognize the message.

  In addition, the electronic device performs data communication via the public line network, stores data by the communication, and controls the electronic device based on data stored in the authentication system among the stored data. . Therefore, according to this authentication system, since the data used in the authentication system is distributed via the public line, the electronic device is used in the authentication system without storing the data in the electronic device in advance. It becomes possible.

  In addition, since the electronic device also includes means for communicating authentication data via the public line network, the transmission form of the authentication data can be diversified and the convenience during authentication can be improved.

  In the present embodiment having such a configuration, even when the back cover member 105 is made of metal (conductor) and the metal member 106 is built in the case 103, as shown in FIG. In addition, when data is transmitted / received, a magnetic flux path that passes from the upper surface to the lower surface of the case 103 is secured, and the data carrier antenna coil 110 is separated from the back cover member 105, so that the back cover member 105 is made of metal. However, the rate at which it hinders communication is extremely small. Therefore, it is possible to ensure good communication while maintaining waterproofness (pressure resistance), impact resistance, robustness, and environmental resistance.

(Fourth embodiment)
14 to 16 are diagrams showing a wristwatch 400 which is a data communication apparatus according to the fourth embodiment of the present invention.
As apparent from FIG. 14, the wristwatch 400 has an appearance as a wristwatch for outdoors or sports, and is made of a watch body 402 and a resin made to be engaged with both ends of the watch body 402. It consists of wristbands 403 and 403.

  As shown in FIGS. 15 and 16, the watch body 402 has a case 404 made of reinforced resin, which is an internal case having the canopy portions 441 and 441 to which the wristbands 403 and 403 are locked, and an upper portion of the case 404. And the resin bezel cover 405 which is an outer case which covers an outer periphery has the structure covered. A metal display frame fixing member 406 is insert-molded above the inside of the case 404. A resin-made display frame member 407 is disposed on the back side of the display frame fixing member 406, while a hard transparent member 408 that closes the upper side of the case 404 is provided on the waterproof packing 409 on the front side of the display frame fixing member 406. It is mounted through. A plurality of keys (operation buttons) 410 and the like are attached to the peripheral wall of the case 404 covered with the bezel cover 405.

  Further, a synthetic rubber module cover member 412 and a module fixing member 413 are overlapped inside the case 404, and a watch module 414 and a module cover member 415 are accommodated in that order in order, and the lower opening of the outer case 404 is opened. The part is sealed by a back cover member 417 via a waterproof packing 416.

  The back cover member 417 is entirely formed of a magnetic material. Examples of the magnetic material include metals, alloys, compounds, magnetic powders such as iron and ferrite, mixtures of magnetic powders, ceramic materials, and the like. The sintered product is suitable.

  The outer surface of the back cover member 417 is covered with a resin case cover 418.

  The timepiece module 414 includes a timepiece LSI substrate 421 and a data carrier module 422 positioned by a module housing member 419 and a module housing member 420 (not shown in FIG. 15). An LCD panel 423 is provided.

  The data carrier module 422 is a data carrier IC substrate 425 having a data carrier IC 424 incorporating a modulation circuit and encoding / decoding circuit for transmission / reception signals, a data memory for storing data such as ID, and a control circuit for transmission / reception and authentication. And a data carrier side antenna coil 426 that is connected to the data carrier IC substrate 425 and transmits and receives signals by electromagnetic induction. The data carrier IC substrate 425 is assembled side by side with the watch LSI substrate 421, and the data carrier side antenna coil 426 is assembled on the outer periphery of the watch LSI substrate 421 so as to be fitted to the inner wall surface of the module housing member 420. It has been.

  In the wristwatch 400 having the above configuration, the user (authenticated person) brings the wristwatch 400 close to the reader / writer of the electromagnetic induction type or electromagnetic coupling type RF-ID system described in the related art. Thus, the wristwatch 400 itself is used as the ID Tag. At this time, in the wristwatch 400, since the back cover member 417 is formed of a magnetic material as described above, as shown in FIG. 17, the gap between the reader / writer side antenna coil 30 of the reader / writer 70 and the like is provided. When the induction electromagnetic field is formed, the magnetic flux passes through the back cover member 417 and passes therethrough. That is, a magnetic flux path is formed from the hard transparent member 408 on the upper surface of the watch body 402 through the data carrier side antenna coil 426 and the back cover member 417 in the case 404. Moreover, this magnetic flux path is the same when the case 404 described above is made of metal.

  Therefore, the case 404 and the display frame fixing member 406 can be made of metal, and the back cover member 417 has higher strength than the case where the back cover member 417, which must be thin, is made of resin. Can be secured. Therefore, it is possible to ensure good communication while maintaining waterproofness (pressure resistance), impact resistance, robustness, and environmental resistance. As a result, the decorativeness can be improved and the appearance and design can be varied according to the tastes and uses of the customer group.

(Fifth embodiment)
18 and 19 are cross-sectional views of a watch main body 502 showing a fifth embodiment of the present invention.

  That is, in this embodiment, a back cover member 517 for closing the lower opening of the case 404 is formed of a metal material, and a battery replacement hole is closed in a part of the back cover member 517. A battery replacement opening / closing lid 535 is mounted. The battery replacement opening / closing lid 535 is provided at a substantially central portion of the back cover member 517 and corresponding to the inner peripheral portion of the data carrier side antenna coil 426. The battery replacement opening / closing lid 535 is made of a magnetic material. Examples of the magnetic material include metals, alloys, compounds, magnetic powder such as iron and ferrite, mixtures of magnetic powder, ceramics, and the like. A sintered material such as a material is suitable.

  Other configurations are the same as those described in the first embodiment.

  In such a configuration, as shown in FIG. 19, when an induction electromagnetic field is formed between the reader / writer-side antenna coil 30 of the reader / writer 70 and the like, the magnetic flux is opened and closed for battery replacement. This is transmitted through the region R corresponding to 535. That is, a magnetic flux path is formed from the hard transparent member 408 on the upper surface of the watch body 502 through the data carrier side antenna coil 426 and the battery replacement opening / closing lid 535 in the case 404. Moreover, this magnetic flux path is the same when the case 404 described above is made of metal. Therefore, the same effect as that shown in the fourth embodiment can be obtained.

  The battery replacement opening / closing lid 535 may be replaced with a resin or ceramic that can transmit magnetic flux. Even in this case, the above-described magnetic flux path is formed during communication with the reader / writer 70 and the like. Therefore, the same effect can be acquired also in that case.

  In the present embodiment and the fourth embodiment, the case 404 is made of reinforced resin. However, as described above, the watch main bodies 402 and 502 penetrate the upper and lower surfaces thereof. Since a magnetic flux path is secured in the direction, data can be transmitted and received even when the case 404 is made of metal. Therefore, by making the case 404 metal, impact resistance and robustness can be improved.

(Sixth embodiment)
FIG. 20 is a cross-sectional view of a watch main body 602 showing a sixth embodiment of the present invention.

  That is, in the present embodiment, similarly to the fourth and fifth embodiments, a metal display frame fixing member 406 is insert-molded above the inside of the resin case 404. Inside the case 404 is a module cover member 412 made of synthetic rubber and the like, and a clock module 414 in which a data carrier module 422 is integrated and a module cover member 415 are accommodated in that order. The lower opening of the case 404 is sealed with a back cover member 417 via a waterproof packing 416. In the present embodiment, the back cover member 517 is formed of a metal material, and the timepiece module 414 is positioned at a location away from the back cover member 517 by the module cover member 415 or the like.

  In such a configuration, although the back cover member 417 is made of metal, the above-described metal display frame fixing member 406 is located on the upper side of the case 404, and metal parts are present on the lower side of the case 404. Therefore, the magnetic flux can pass through the peripheral wall on the lower side of the case 404. Therefore, as described above, when an induction electromagnetic field is formed between the reader / writer side antenna coil 30 of the reader / writer 70 and the like, the magnetic flux passes from the upper surface of the watch body 602 to the lower side of the case 404. A magnetic flux passage route 600 is formed (see FIG. 22).

  Therefore, when the back cover member 417 is made of metal, it is possible to ensure good communication while maintaining waterproofness (pressure resistance), impact resistance, robustness, and environmental resistance. In addition, since the data carrier side antenna coil 426 is provided at a position away from the back cover member 417, even if the back cover member 417 is made of metal, the rate of hindering communication is extremely small. Therefore, it is possible to ensure good communication.

(Seventh embodiment)
FIG. 21 is a cross-sectional view of a timepiece main body 702 showing a seventh embodiment of the present invention.

  That is, in the present embodiment, the back cover member 417 is formed of a metal material as in the sixth embodiment, while the outer peripheral surface of the data carrier side antenna coil 426 is connected to the inner cover of the module cover member 412. It has a configuration fitted to the lower side of the face case 404.

  Even in such a configuration, similarly to the fifth embodiment, the magnetic flux can pass through the lower peripheral wall of the case 404. As shown in FIG. 22, the reader / writer side antenna coil of the reader / writer or the like is provided. When an induction electromagnetic field is formed between the magnetic field and the magnetic flux path 30, a magnetic flux path is formed in which the magnetic flux passes from the upper surface of the watch body 702 to the lower side of the case 404. Even if the back cover member 417 is made of metal, the rate at which it hinders communication is extremely small. Therefore, it is possible to ensure good communication.

  In the present embodiment and the sixth embodiment, the case 404 is made of resin, and a magnetic flux passage is secured on the lower side thereof. All or a part in the vertical direction may be formed of a magnetic material. Even in such a case, when data is transmitted and received, a magnetic flux path passing through the data carrier side antenna coil 426 in the case 404 and the peripheral wall of the case 404 can be formed from the hard transparent member 408 on the upper surface of the watch main body 602 or 702. The same effect as described above can be obtained.

(Eighth embodiment)
23 and 24 are cross-sectional views of a watch body 802 showing an eighth embodiment of the present invention.

  That is, in this embodiment, the back cover member 417 is formed of a metal material as in the sixth and seventh embodiments, but the data carrier module 822 is configured independently of the watch module 814. ing. Specifically, the position of the data carrier module 822 is fixed to the lower part of the timepiece module 814 at a distance of several millimeters from the back cover member 417.

  The data carrier module 822 includes a data carrier IC substrate 825 having the data carrier IC 824 described above, a data carrier side antenna coil 426, and a plate-like magnetic plate formed of a magnetic material and provided with a recess 837 in the central portion. And a core 836.

  The first data carrier side antenna coil 826 and the second first data carrier side antenna coil 827 can communicate with the reader / writer side antenna coil at different carrier frequencies. For example, the first data carrier side antenna coil 826 can transmit / receive data to / from the reader / writer side antenna coil at a carrier frequency of 125 KHz and the second data carrier side antenna coil 827 at 13.56 MHz. Therefore, according to this example, the same wristwatch (ID Tag) can be used for two types of RF-ID systems having different carrier frequencies. Of course, by incorporating a larger number of antenna coils on the data carrier side, the same wristwatch can be used for a wider variety of systems.

The data carrier module 1022 includes a data carrier IC substrate 825 having the data carrier IC 824, a data carrier side antenna coil 426, and a plate-like magnetic core 836 made of a magnetic material.

  In the present embodiment, unlike the eighth embodiment, the linear conductive members constituting the data carrier side antenna coil 426 are arranged on the outer periphery of the disc-shaped magnetic core 436 on the front and back surfaces of the watch body 1002. Is wound several times to several tens of times with the horizontal direction perpendicular to the vertical direction passing through the substrate as a winding axis, and a data carrier IC substrate 825 is disposed above the disk-shaped magnetic core 436.

  Other points are the same as in the eighth embodiment described above.

  In such a configuration, the linear conductive member constituting the data carrier side antenna coil 426 is several times around the outer periphery of the disk-shaped magnetic core 436 disposed in the horizontal direction of the watch body 1002 with the horizontal direction as the winding axis. Since it is wound several tens of times, when an induction electromagnetic field is formed between the reader / writer-side antenna coil 30 of the reader / writer 70 and the like, a part of the magnetic flux is transferred from the upper surface of the watch body 1002 to the case. As shown in FIG. 34, most of them pass from the lower side of the case 404 to the inside of the data carrier side antenna coil 426, that is, a circle around which the data carrier side antenna coil 426 is wound. It passes through the plate-shaped magnetic core 836 and comes out from the other lower side of the case 404. Therefore, since the magnetic flux of the induction electromagnetic field can be passed through the watch main body 1002 in the horizontal direction, the same effect as that shown in the eighth embodiment described above can be obtained.

(Eleventh embodiment)
FIG. 35 illustrates an antenna that can be used for transmitting and receiving signals by electromagnetic induction in the tenth embodiment.

(Twelfth embodiment)
FIG. 36 shows a twelfth embodiment of the present invention.

  The present embodiment shows a modified example of the display frame fixing member 406 inserted into the resin case 404 described above. In addition, although each planar shape was shown as circular (or substantially circular), actually, it shape | molds in the required planar shape.

  Hereinafter, in order, the display frame fixing member 406 of FIG. 36A is formed into a shape having unevenness 4061 (see FIG. 36G) in the radial direction over the entire circumference, and the shape is previously transmitted and received data Is tuned so that the inductance component in the frequency band used in the above is increased in comparison with the basic cylindrical shape.

  In addition, the display frame fixing member 406 in FIG. 36B has a shape in which a plurality of concave portions 4062 are provided at equal intervals around the entire upper edge and the lower edge, and the display frame fixing member 406 in FIG. 36C. Has a shape in which a plurality of convex portions 4063 (see FIG. 36H) are provided at predetermined intervals around the entire upper edge.

  23B and 23C are formed in a variety of cross-sectional shapes in the direction of cutting the ring, and these shapes are preliminarily used in the frequency band used for data transmission / reception. The inductance component is tuned to have a shape that increases compared to the basic cylindrical shape.

  That is, in the display frame fixing member 406 having the above-described shape, the impedance is larger than that of the basic cylindrical shape. Therefore, the display frame fixing member 406 is generated when data is transmitted / received as compared with the case where the shape is simply formed into the basic shape. Eddy current is reduced. Therefore, if the display frame fixing member 406 in the watch body described above is the one shown in FIGS. 36A to 36C, transmission / reception troubles caused by eddy currents can be reduced even if the display frame fixing member 406 is made of metal. By making the frame fixing member made of metal, the communication performance can be improved while maintaining the basic performance such as impact resistance and robustness of the watch body 2.

  On the other hand, the display frame fixing member 406 shown in FIG. 36D is obtained by connecting both ends of a substantially Ω-type member by screwing with the non-conductive member 47 interposed therebetween. In such a display frame fixing member 406, since the electrical resistance at the coupling portion is larger than that of the other general portions, the eddy current generated during data transmission / reception is reduced. Moreover, the mechanical strength can be ensured by the annular shape. Therefore, the same effect as described above can be obtained. Note that the display frame fixing member 406 is shown as being screwed with the separate member 47 sandwiched between the joint portions, but the other ends may be joined by other joining means that increase the contact resistance. Thus, the same effect can be obtained.

  Further, the display frame fixing member 406 shown in FIG. 36E is provided with a coating layer 48 of a coating material containing particles or powder of magnetic material on the inner peripheral surface thereof. Eddy currents generated during transmission and reception can be reduced, and the same effect as described above can be obtained.

  The display frame fixing member 406 shown in FIG. 36F is provided with the coating layer 48 over the entire surface, and the same effect as that shown in FIG. 36E can be obtained.

  Further, in addition to the one shown in FIG. 36, the display frame fixing member 406 is formed of a non-conductive material such as reinforced resin or ceramic having the same strength, or another metal having a low conductivity. In other words, since the electrical resistance increases, the eddy current generated by receiving the induction electromagnetic field can be eliminated or reduced, and the transmission / reception failure caused by the eddy current can be reduced (eliminated).

  In the present embodiment, the structure of the display frame fixing member 406 of the watch body described above has been described. However, for example, when the case 404 is made of metal, the case 404 is used. In the case where there are other metal annular members that form a hollow portion through which the magnetic flux of the data carrier antenna coil 426 passes, the same effect can be obtained by adopting the shape and the like described above. Obtainable.

  In this embodiment, as shown in FIG. 56, when the tilt sensor 2207 detects a state of tilting at a constant angle for a predetermined time or more, it outputs a tilt sensor detection signal 56A at a predetermined timing. Then, the data carrier IC 1306 is turned ON at intervals of t1 at every output timing of the tilt sensor detection signal 56A, and generates the data carrier control strobe signal 56B. Only during this period, the periodic transmission signal 56C from the reader / writer 1310 side is received, and the response / transmission / reception processing 56D on the data carrier IC side corresponding to the transmission signal 56C is executed.
