Description

  The present invention relates to an identification system and an identification method, and more particularly to an identification system and an identification method using an IC chip embedded in the tooth of the person.

  There are disasters that cause many victims, such as the Great Hanshin Awaji Earthquake and the Great East Japan Earthquake. When the bodies of victims of these disasters are found, it is necessary to identify who the bodies are. Heretofore, for such identification, it has been determined from the tooth shape and the dental treatment mark by the dentist. And the body is handed over to the bereaved based on such judgment.

  In addition, when an elderly person suffers from dementia who is deceived and protected, it may not be possible to identify who the person is. If you know who is from the belongings etc., it is possible to contact the family etc., but if it does not hesitate, you may have spent in a state where someone happened to be accepted at the facility you received. In addition, people who are hospitalized without knowing who or who is hospitalized or who is protected by each municipality are increasing, and the cost burden is increasing year by year because of cerebral infarction and the like. A system that identifies the person who has suffered from such a person with dementia or who has fallen due to cerebral infarction is an important task that the government should work on. It is also urgent to build such a system.

  Hereinafter, the present invention will be described by way of the illustrated embodiments. The embodiment shown in FIGS. 1 and 2 relates to a person authentication system in which an IC chip is embedded using a porcelain laminate plate which is a kind of ceramic aesthetic plate. That is, here, when a porcelain laminate plate is joined to the outer surface of the front side of a tooth consisting of a denture or a natural tooth, the porcelain laminate plate is used to bury an IC chip inside the front tooth.

  This will be described below with reference to FIGS. 1 and 2. A shallow recess 11 is formed on the front surface of an anterior tooth 10 consisting of a denture or a natural tooth by dental treatment. The recess 11 is a very shallow recess having a thickness of about 0.7 to 1 mm. The front teeth 10 in which such a recess 11 is formed are molded using silicone rubber or alginic acid (agar). Then, using the mold, a plaster mold 12 having the same shape as the front teeth 10 is created. The plaster mold 12 is provided with a rectangular recess 13 on the front side as shown in FIG. The recess 13 has the same shape as the recess 11 formed in the front teeth 10. Then, intentionally, the projection 14 is formed at a predetermined position of the recess 13 of the plaster mold 12. The protrusion 14 is for forming a recess for embedding the IC chip later. Then, the recess 13 of the plaster mold 12 is filled with the porcelain powder and the resin solution, and the baking is performed. Thereby, a thin plate-shaped porcelain laminate plate 18 corresponding to the recess 13 of the plaster mold 12 is formed.

  The porcelain laminate plate 18 has a shape that matches the recess 11 of the front teeth 10, and the recess 14 is formed by the protrusion 14 on the back surface thereof. Therefore, the IC chip 20 is disposed in the recess 19, and the liquid resin is covered and fixed from above. As a result, the IC chip 20 is embedded in the recess 19 of the porcelain laminate plate 18 (see FIG. 2). After that, as shown in the lowermost part of FIG. 1, the porcelain laminate plate 18 is joined to the front side of the front teeth 10 by mounting the above-mentioned porcelain laminate plate 18 in the recess 11 of the front teeth 10.

  The IC chip 20 embedded in the recess 19 of the porcelain laminate plate 18 on the front side of the front teeth 10 has the name, date of birth, address, contact information, blood type, medical history, allergy of the person to whom the IC chip 20 is attached. It is possible to make various writings necessary for authentication, such as substance, history of dental treatment, photographs of teeth, etc. Writing of the information may be performed before attaching the IC chip 20 to the teeth or after attaching the teeth to the teeth. By accessing the IC chip 20 using the reader / writer head 24 shown in FIG. 2, the above various information written in the IC chip 20 can be read, and this can be taken out by the detection circuit 25. It will be possible. By supplying the information taken out by the detection circuit 25 to an information processing apparatus such as a personal computer, it becomes possible to take out various kinds of information necessary for the authentication of the person very easily and surely.

  The IC chip 20 is, for example, a rectangular semiconductor bare chip having an extremely small size of 0.4 × 0.4 × 0.3 mm. Such an IC chip 20 is inserted into a recess 0.5 to 0.7 mm deep inside of the porcelain laminate plate 18 mounted on the surface of the teeth to enhance the aesthetics of the teeth, and the adhesive By fixing the porcelain laminate plate 18 to the front teeth 10 as well as fixing them with the above, it becomes possible to hold the information necessary for the personal authentication on the front teeth 10. The porcelain laminate plate 18 to which the IC chip 20 is attached can be fixed to the inside of the oral cavity of the anterior teeth 10 consisting of dentures or natural teeth by resin cement. As a resin cement, an ultraviolet curing resin is suitably used. An appropriate mark such as an antenna mark may be provided on the surface of the front teeth 10 or the porcelain laminate plate 18 so that it can be determined that the IC chip 20 is attached.

  The IC chip 20 is accessible by the reader / writer head 24, and writing and reading with respect to the IC chip 20 are performed using the reader / writer head 24 and the detection circuit 25. Here, the contents written on the IC chip 20 may be the name, date of birth, address, contact information, blood type, medical history, allergic substance, history of dental treatment, dental photographs, etc. Can be written arbitrarily. By checking the content with the reader / writer only when there is a natural disaster or an emergency, and it is necessary to confirm the identity, it is possible to take out information about the identity quickly and reliably.

  The writing of information on the IC chip 20 and the management of the information on reading out the information from the IC chip 20 are approved by the person or the family regarding the written content, or alternatively by the dentist after receiving the approval of the adult guardian. Write using a dedicated IC writer. Moreover, it is preferable that the mounting of the above-mentioned IC chip 20 is performed within the responsibility of the act of dental treatment. In addition, it is preferable that only a dental doctor possess a reader of the IC chip 20 so as to be able to obtain and disclose information written by a proposal by a municipal mayor and a police document. The reader / writer preferably determines an individual identification number so that identification of the information source (dentist) can be performed.

  In the above-mentioned embodiment, the example which used the porcelain laminate plate was explained as a ceramic esthetic plate put on a tooth. However, other ceramic plates may be used as the ceramic aesthetic plate, and a zirconia laminate plate may be used.

  Another embodiment will now be described with reference to FIG. This embodiment is an example of burying an IC chip to an artificial tooth (denture) comprising a plurality of dentures 30. That is, here, the dentures 30 are erected on the common artificial gingiva 31. The artificial gum 31 is made of a polymer material such as PA (nylon), PET (ester), PC (polycarbonate), PP (polyolefin) and the like. Then, the recess 32 may be formed at an appropriate position such as the side surface of the artificial gingiva 31 and the IC chip 33 may be embedded in the recess 32. Here, the IC chip 33 may write and read information in the same manner as the IC chip 20 embedded in the porcelain laminate plate 18 described above.

  Next, still another embodiment will be described with reference to FIG. This embodiment is an example in which an IC chip is embedded in the implant denture 35, and the implant denture 35 is mounted on the abutment 36. The abutment 36 is joined to the upper portion of the implant body 37 having a male screw formed on the outer peripheral portion, and the implant denture 35 is fixed to the implant body 37 by a bolt 38 penetrating the central portion.

  Here, a circular small hole 42 is formed on the side of the implant denture 35, and the IC chip 43 is embedded in the small hole 42. The IC chip 43 is fixed by liquid resin after being inserted into the small hole 42, and the lid piece 44 is mounted from above to be securely embedded.

  Even in such a configuration, the IC chip 43 in the small hole 42 provided on the side surface of the implant denture 35 can read out the information necessary for the personal authentication, whereby the personal authentication is surely performed. .

  Although the present invention has been described above by the illustrated embodiments, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea of the present invention. For example, in the above-described embodiment, the IC chip is embedded using a porcelain laminate plate or using a resin-made artificial gum or an implant denture, for example, in the treatment of a dental caries part of a natural tooth. The IC chip can be embedded in a part of the treatment site, thereby performing identity verification. The IC chip may be fixed to the side of another normal natural tooth or denture with an adhesive. The IC chip is very small, so that it is possible to easily embed the IC chip in a predetermined part of the tooth only by forming a small recess on the side of a normal tooth.

  The present invention is applied to a personal authentication system capable of performing personal authentication of a deceased person's body or who survives but who can not be identified due to dementia, brain disorder, etc. quickly and reliably it can.
