For the head drive unit 16, for example, neodymium, which is a rare metal, is used as a magnetic material. An RFID (Radio Frequency Identification) chip 21 a is attached inside the hard disk drive device 10.

  The RFID chip 21a adopts a passive type, and functions as an IC chip unit that functions as a memory, a control unit that performs encoding / decoding of communication contents, an antenna for supplying power to the IC chip and transmitting / receiving information. It consists of an antenna part. With these configurations, information can be transmitted and received in a non-contact manner while receiving power from an RFID reader 62 described later using electromagnetic induction.

According to these configurations, unauthorized tampering can be prevented.

  FIG. 5 shows a system configuration of a composition information providing system for acquiring rare metal information from electronic components and electronic equipment 40 during recycling. The composition information providing system includes an information processing terminal 61 for acquiring rare metal information from an electronic component or electronic device 40 on which the RFID chip 21 is mounted, and a key management server 51 connected to the information processing terminal 61 via a network 55. And composed of

  In FIG. 5, the key management server 51 is a server that manages key information of encrypted rare metal information included in the electronic component or the electronic device 40. As described above, the key management server 51 manages the encryption key K1, and also manages the decryption key K2 paired with the encryption key K1. The key management server 51 performs an authentication unit 52 (terminal identification processing unit) that authenticates whether or not the terminal is an authorized user, and performs control to transmit the decryption key K2 only to the authorized user terminal. And a key management unit 53. The key management server 51 can transmit and receive information to and from the information processing terminal 61 via the network 55 by the communication unit 54 (decoded information transmission unit).

  For example, the information processing terminal 61 is arranged in a recycling factory, and an RFID reader 62 is connected to the information processing terminal 61. Information of the RFID chip 21 mounted on the electronic component or the electronic device 40 is read by the RFID reader 62. Further, the information processing terminal 61 is provided with an input unit 64 such as a keyboard and a mouse and a display unit 65. The information processing terminal 61 stores the key acquisition control unit 66 that controls acquisition of the decryption key K2, the storage unit 67 that stores the decryption key K2, and the acquired decryption key K2 or the storage unit 67. And a decryption unit 68 (composition information acquisition unit) for decrypting the rare metal information using the decryption key K2. The information processing terminal 61 can transmit and receive information via the network 55 by the communication unit 69.

  FIG. 6 is a flowchart showing processing of the recording device 100 when the rare metal information included in the electronic component or the electronic device 40 is encrypted and stored in the RFID chip 21.

  As illustrated in FIG. 6, the recording apparatus 100 acquires information on rare metals in each part of the electronic component or the electronic device 40 (Step S <b> 1).

  For example, in the case of the hard disk drive device 10 shown in FIGS. 1 to 3, it is conceivable that the portion of the substrate 17 is removed and recycled separately. Considering this, it is divided into a drive system and a substrate system. For example, RD01 is assigned as an identification code to the drive system, and RD02 is assigned as an identification code to the substrate system.

  As shown in FIG. 2, the drive system is provided with a platter 14, a disk drive motor 15, and a head drive unit 16. The platter 14 contains, for example, ruthenium as a rare metal. The drive motor 15 includes, for example, neodymium or cobalt as a rare metal, and the head drive unit 16 includes, for example, neodymium as a rare metal. Thereby, the rare metal information as shown in FIG. 7A is recorded on the RFID chip 21a.

  As shown in FIG. 3, the substrate system includes a substrate 17 and a circuit component 18, and the pattern of the substrate 17 includes gold or silver as a rare metal. Tantalum is included as a rare metal. Thereby, the rare metal information as shown in FIG. 7B is recorded on the RFID chip 21b.

  Next, in FIG. 6, the recording apparatus 100 encrypts the corresponding part of the rare metal information (step S2). Then, the recording apparatus 100 stores the identification code, the encrypted rare metal information, and the basic information in the RFID chip 21 (step S3).

  For example, in the case of the hard disk drive device 10 described above, two RFID chips 21a and 21b of a drive system and a substrate system are prepared. As shown in FIG. 7A, the names of the rare metals contained in the drive system (ruthenium, neodymium, cobalt, nickel), their contents (100 μg, 10 g, 10 g, 2 g, 20 mg), and part names (Platter, head drive unit, disk drive motor) are associated with each other and encrypted as rare metal information of the drive system. The RFID chip 21a stores the identification code RD01, the rare metal information of the drive system thus encrypted, and the basic information.

  Further, as shown in FIG. 7B, the substance names (gold, silver, tantalum) of rare metals contained in the substrate system, their contents (15 mg, 70 mg, 0.1 μg), component names (substrate and IC pattern, capacitor and other circuit components) are associated with each other, and encrypted as rare metal information of the board portion. The RFID chip 21b stores the identification code RD02, the substrate-based rare metal information encrypted in this way, and basic information.

  The basic information includes information necessary for decrypting the encrypted rare metal information, and the basic information is stored in the RFID chip 21 without being encrypted. The basic information includes information for managing authentication for decryption, or information on contact information (URL (Uniform Resource Locator), etc.) of an organization, organization, company, organization, etc. that is entrusted with management.

  FIG. 8 is a flowchart illustrating processing of the RFID reader 62, the information processing terminal 61, and the key management server 51 when the information processing terminal 61 acquires rare metal information included in the electronic component or the electronic device 40.

  As shown in FIG. 8, the RFID reader 62 reads information from the RFID chip 21 attached to the electronic component or the electronic device 40, and transmits the information to the information processing terminal 61 (step S101).

  The information processing terminal 61 determines whether or not the decryption key K2 is stored in the storage unit 67 (step S102). If the decryption key K2 is stored, the information processing terminal 61 reads the decryption key K2 (step S103). ). Further, the information processing terminal 61 decrypts the rare metal information using the decryption key K2 (step S104). Then, the decoded rare metal information is displayed on the display unit 65 (step S105).

  On the other hand, if the decryption key K2 is not stored in step S102, authentication is performed between the information processing terminal 61 and the key management server 51 (step S106). The authentication can be automatically performed by using the basic information recorded on the RFID chip 21 in addition to the user operating the information processing terminal 61 inputting the ID and password. Here, basic information is transmitted to the key management server 51.

  When receiving the basic information, the key management server 51 determines whether authentication is established (step S107). Here, if the authentication is not established, the connection is rejected (step S108). In this case, the information processing terminal 61 cannot obtain the rare metal information because the decryption key K2 cannot be obtained.

  When authentication is established in step S107, the key management server 51 transmits the decryption key K2 to the information processing terminal 61 (step S109). The information processing terminal 61 stores the decryption key K2 in the storage unit 67 (step S110). Then, the rare metal information is decrypted using the decryption key K2 (step S104). Also, the decoded rare metal information is displayed on the display unit 65 (step S105).

  For example, in the case of the hard disk drive device 10 described above, rare metal information as shown in FIGS. 7A and 7B is encrypted and stored in the RFID chips 21a and 21b. The rare metal information read from the RFID chips 21a and 21b is decoded and displayed on the display unit 65. As a result, as shown in FIG. 9, information on rare metals included in the hard disk drive device 10 is displayed on the display unit 65.

  In FIG. 9, the drive-system rare metal information and the substrate-type rare metal information are collectively displayed, but may be displayed for each identification code.

  As described above, in the embodiment of the present invention, rare metal information is encrypted and stored in the RFID chip 21 in the electronic component or the electronic device 40. At the time of recycling, the information read from the RFID chip 21 is decrypted, and rare metal information is acquired.

  Here, the decryption key K2 for decrypting the rare metal information is managed so as to be informed only to terminals that have received permission. In this way, in a regular recycling factory, rare metal information can be easily obtained, and for other than that, the rare metal information can be kept secret.

  The present invention is not limited to the above-described embodiments, and various modifications and applications can be made without departing from the gist of the present invention.

  For example, in the above-described example, the rare metal information is encrypted and recorded on the RFID chip 21 as the composition information, but the composition information is not limited to the rare metal information. For example, if synthetic resin information is recorded as the composition information, it is possible to determine whether the information can be recycled, whether it can be discarded, or the like, using the synthetic resin information.

  In the above-described example, the case where the electronic component or the electronic device 40 is recycled has been described. However, the present invention is not limited to this, and can be similarly applied to the case where other components and products are recycled. . Further, a program for executing each process of the composition information providing system shown in the above embodiment and various recording media (CD-ROM, flash memory, etc.) storing the program are also included in the scope of the right of the present invention.
