JP4189340B2 - Delivery box system and delivery box program - Google Patents

Description

  The present invention relates to a delivery box system and a delivery box program, and more particularly, to a delivery box system and a delivery box program used in an apartment house such as a condominium or a private home.

  In the conventional delivery box, one key belonging to each delivery box is provided, and unlocking / locking is performed using it. The delivery person locks the package in an empty delivery box, and then puts the key in the recipient's mailbox. The resident receives the key in the mailbox, inserts the key into the keyhole of the delivery box, unlocks it, and takes out the package.

  The first problem with this type of conventional delivery box is that the key is lost. Keys are handed over to any person every time the box is used, and there are many problems that keys are lost because the administrator cannot identify the key. If the key is lost, the box becomes unusable, or the key part needs to be replaced, which is expensive.

  The second problem is that the parcel delivery box can be easily taken out if only the key is available. Since the identity of the recipient has not been verified, there is a problem that if the key is accidentally inserted into the third party's mailbox, the third party can easily unlock it. . There is also concern about theft by key duplication and picking.

  Therefore, in recent years, a delivery box for solving these problems has been proposed (for example, see Patent Document 1).

  In order to solve the first problem, in the conventional delivery box according to Patent Document 1, an absent ID tag is issued by the tag issuing device 13 each time instead of the above key, and the absence The locker is unlocked using the ID tag for business. In other words, when the recipient is absent, the absent ID tag is issued by the tag issuing device 13 and inserted into the recipient's house, and the package is stored and stored in the locker of the storage. The recipient takes the absent ID tag and goes to the storage, unlocks by inserting the absent ID tag into the operation part of the rocker, and takes out the package.

  In order to solve the second problem, in the conventional delivery box according to Patent Document 1, after the absence ID tag is inserted, identity verification using an ID card is performed and it is recognized as the identity. Only try to unlock the locker door.

Japanese Patent Laid-Open No. 10-312486 (FIG. 12)

  In the conventional delivery box according to Patent Document 1, identity verification is performed using an ID card that stores ID information for identifying a user, but when a malicious third party obtains the ID card, Just by inserting it into the ID card insertion slot, it is possible to easily impersonate the person and take out the baggage, resulting in a problem of low security.

  The present invention has been made to solve such a problem, and an object thereof is to obtain a delivery box system and a delivery box program that ensure high security with a simple operation.

Embodiment 1 FIG.
First, the configuration of the delivery box system according to Embodiment 1 of the present invention will be described with reference to FIG. As shown in FIG. 1, the delivery box system according to the present embodiment is provided with a management terminal 1 for managing the entire system. The management terminal 1 is connected to a delivery box 2, a printer 3, and an IC card reading / writing device 4. The management terminal 1 controls the unlocking / locking of the electronic lock provided on the door of the delivery box 2. Further, the management terminal 1 outputs a receipt 5 notifying that the package 8 has arrived from the printer 3. Since it is necessary to deliver the receipt 5 which is a paper medium to the resident, the delivery person uses, for example, a mailbox 6. The resident uses the IC card 7 for the operation of unlocking the electronic lock provided on the door of the delivery box 2. Here, the IC card 7 will be described as an example of a portable storage medium. However, the present invention is not limited to this, and any portable storage medium can be used as long as it can store a “secret key” described later. Also good.

  In the present embodiment, “public key” and “secret key” of the public key cryptosystem are generated in advance, the “public key” is stored in the management terminal 1, and the “secret key” is stored in the IC card 7. These are stored and used as “keys”. That is, in this embodiment, an electronic key is used instead of a physical so-called ordinary key. The public key cryptosystem will be briefly described. Typical methods for encrypting data include a “common key encryption method” and a “public key encryption method”. In the common key cryptosystem, the sender and the receiver use the same key to perform encryption processing and decryption processing. On the other hand, in the public key cryptosystem, encryption processing and decryption processing are performed using a pair of two keys (a public key and a secret key). In other words, the data encrypted with the public key (or private key) cannot be decrypted unless the private key (or public key) paired with the public key (or private key) is used. .

  Next, a processing flow of the delivery box system according to the present embodiment will be described. FIG. 2 is a flowchart showing an outline of the overall processing flow of the delivery box system according to the present embodiment. First, the delivery person's procedure will be described. As shown in FIG. 2 (a), first, when the address resident is absent, the delivery person puts the package 8 into the empty delivery box 2 (step S1), and operates the management terminal 1 to operate the delivery box 2 Is locked (step S2). The delivery person puts the receipt 5 output from the management terminal 1 into the mailbox 6 of the resident of the package and completes the work on the delivery person side (note that, for the sake of simplicity, the delivery box 2 is , Assuming there is a sufficient number, not considering that there is no room.)

  Next, the recipient procedure will be described. As shown in FIG. 2B, when the resident receives the receipt 5 (step S4), the delivery terminal 2 is unlocked by operating the management terminal 1 based on the information described in the receipt 5. The door is opened (step S5), and the parcel 8 is received (step S6).

  3 to 5 are flowcharts showing processing of the management terminal 1. 3 shows processing at the time of moving in, FIG. 4 shows processing at the time of delivery, and FIG. 5 shows processing at the time of receipt.

  First, the process at the time of moving in will be described. As shown in FIG. 3, at the time of moving in, the resident uses the management terminal 1 to issue a “public key” and a “secret key”. First, the resident inputs a room number (step S10) and a personal identification number (step S11) into the management terminal 1, and inputs a random value used for key generation (step S12). Since the random value is used as a trigger signal for key generation, an appropriate meaningless value is input with a keyboard, or a meaningless movement is performed using a mouse. Extract. Next, using the random value obtained in step S12, a public key and a secret key are generated by, for example, RSA (step S13). Next, the generated public key and room number are stored in the internal memory of the management terminal 1 (step S14). Next, the secret key is stored in the IC card 7 by the IC card reading / writing device 4 of the management terminal 1 (step S15).

  Next, processing at the time of delivery will be described. As shown in FIG. 4, the process at the time of delivery uses a “password” that is randomly generated and a “public key” registered in the destination room number of the package. First, the delivery person inputs the box number (box number) of the parcel delivery box 2 containing the package and the destination room number of the package into the management terminal 1 (steps S20 and S21). By this operation, a “password” is randomly generated (step S22). The “password” may have any value, but for example, a value of about 8 digits consisting of only alphanumeric characters. Next, a plain text is generated by adding the box number of the delivery box 2 containing the package to the “password” (step S23). Next, the management terminal 1 searches for the public key using the destination room number and retrieves it from the internal memory (step S24). Next, the management terminal 1 encrypts the above plain text with the public key and simultaneously outputs a signal for locking the electronic lock of the parcel delivery box 2 containing the package (step S25). Next, the “password” and the encrypted plaintext (hereinafter referred to as “ciphertext”) are stored in the internal memory of the management terminal 1 (step S26), and the receipt 5 in which “password” is described is stored in the printer 3. (Step S27). The receipt 5 is put into the recipient's mailbox 6 by the delivery person.

  Next, processing upon receipt will be described. As shown in FIG. 5, in the process at the time of receipt, first, the recipient inputs “password” described in the receipt 5 contained in the mailbox 6 to the management terminal 1 (step S30), and then moves in. The IC card 7 on which the “secret key” created at this time is stored is inserted into the IC card reading / writing device 4 (step S31), and the personal identification number is input to the management terminal 1 (step S32). The management terminal 1 verifies whether or not the personal identification number matches the value registered in advance with the management terminal 1 and the IC card 7 to authenticate whether or not the person is the person (step S33). If it is determined that the user is not the person, the process is terminated as it is. On the other hand, only when it is determined that the user is the person himself, the operation of using the “secret key” in the IC card 7 is permitted. In other cases, the use operation of the “secret key” in the IC card 7 is prohibited. Next, ciphertext stored in the internal memory of the management terminal 1 using the “password” input in step S30 as a key (the ciphertext is stored in step S26 of FIG. 4). Is taken out (step S34). The ciphertext extracted in step S34 is decrypted using the “secret key” in the IC card 7 (step S35). Only the “password” part is cut out from the decrypted ciphertext, excluding the package box number added in step S23 of FIG. 4 (step S36). It is determined whether or not the “password” of the decrypted ciphertext extracted in this way matches the “password” input in step S30 (step S37). Based on the information, the delivery box 2 of the box No. is unlocked (Step S38), and the box No. is displayed on the display screen of the management terminal 1 (Step S39).

  In this way, using the public key method, the physical key of each delivery box is required by using the “public key” and “secret key” preset by the resident as the delivery box key. This eliminates problems such as lost keys. In the present embodiment, the resident stores and holds the secret key in the IC card 7, and the key manager becomes clear. The delivery box 2 is locked with a “password” randomly generated every time it is used and a “public key” registered in advance, and cannot be opened without using the correct “secret key”. It is possible to make it more difficult to open the parcel delivery box containing the package, and to prevent the malicious third party from taking the package illegally. The delivery box 2 can be opened only with the “secret key” of the resident of the destination room number of the package, and the identity of the person is confirmed by the personal identification number for using the “secret key”. You can deliver your luggage.

  As described above, according to the present embodiment, it is possible to make the delivery box keyless by using the mechanism of the public key cryptosystem and to realize security management of the delivery box. When the resident has a public key encryption method “public key” and “private key”, there is no key belonging to each parcel delivery box. At the same time, the “private key” is managed by the resident and is a personal identification number. Since the confirmation is performed, the security of the delivery box 2 can be improved.

  As a specific effect, since security is strengthened, theft by key duplication and picking can be prevented. In addition, since the key manager becomes clear (the private key [IC card] is not private but privately owned and does not exist in the common place), the system loses lost keys. Unusable boxes are lost due to lost keys.

  In this embodiment, an example of performing identity verification using a personal identification number has been described. However, the present invention is not limited to this, and biometric authentication using a fingerprint or the like may be performed. In that case, the security is further improved.

Embodiment 2. FIG.
In the present embodiment, a process when the IC card 7 is lost or stolen in the delivery box system according to the first embodiment will be described. FIG. 6 is a diagram showing a flow of processing when the IC card is reissued in the present embodiment.

  First, the resident inputs a room number into the management terminal 1 (step S40), and then inserts the IC card 7 into the management terminal 1 and inputs a password (step S41). When the management terminal 1 confirms the identity by the personal identification number and determines that it is the identity (step S42), the management terminal 1 uses the public key in the internal memory of the management terminal 1 based on the room number input in step S40. Is deleted (step S43). Next, the same processing as steps S11 to S14 in FIG. 3 is performed to newly generate a “public key” and a “secret key”, and thereafter use the new “public key” and “secret key”. To.

  According to this embodiment, even if the IC card 7 is lost or stolen, the current “public key” is deleted, and a new “public key” and “secret key” are generated. Thus, even if a malicious third party obtains the IC card 7 and knows the password, unauthorized use can be prevented by updating the “public key”. In addition, when a physical key is used as in the past, if the key is lost or stolen, use of the delivery box is stopped, or the delivery box itself is replaced or delivered. However, in the present invention, since it is an electronic “public key” and “private key”, even if the key is lost or stolen, the delivery box itself must be replaced. It is economical because it is not necessary to replace or replace the key part of the delivery box.

Embodiment 3 FIG.
In the first embodiment, an example has been described in which the receipt 5 in which the password is written is used to notify the recipient that the package is in the delivery box 2. However, in the present embodiment, instead of the receipt 5, Next, an example using electronic mail will be described.

  The e-mail address of the resident is registered together with the room number in the management terminal 1 in advance. The e-mail address may be an e-mail address specified for a mobile terminal such as a mobile phone, or any e-mail address specified for a fixed terminal connected to a communication network such as the Internet, and is arbitrary according to the resident's request. Register. When the parcel is placed in the delivery box 2, a message indicating that the parcel has arrived and a password are written in the body of the e-mail and transmitted to the registered e-mail address. After returning home, the resident performs the same processing as in FIG. 5 using the password of the e-mail and takes out the package from the delivery box 2.

  As described above, in this embodiment, since the recipient is notified by e-mail instead of the receipt 5, the package is surely and promptly (without waiting for the recipient to return home). It is possible to notify the recipient of the arrival, and convenience is improved.

  The receipt 5 and e-mail may be used together.

Embodiment 4 FIG.
In the present embodiment, in addition to the configurations of the first and second embodiments described above, a package for the resident to confirm whether the package addressed to himself / herself has arrived by using a user terminal, a mobile phone, etc. An example in which confirmation means is provided will be described. That is, the management terminal 1 is connected to a communication network such as the Internet, and a room number and a personal identification number are input via the communication network from a user terminal, a mobile phone, etc. It is possible to check whether or not there is a package. When there is no luggage, the management terminal 1 displays a message such as “no luggage” on the display screen of the user terminal or the mobile phone. On the other hand, when there is a baggage, a message such as “I keep my baggage” is displayed. At this time, the password may also be displayed.

  As described above, in this embodiment, since the presence / absence of luggage can be confirmed from a remote place, the resident can confirm the presence / absence of luggage at any time, which is convenient.

Embodiment 5 FIG.
In the first to fourth embodiments described above, the example in which the “secret key” is stored in the IC card 7 has been described. However, in the present embodiment, the “secret key” is stored in the mobile phone instead of the IC card 7. It is made to memorize | store in mobile terminals, such as.

  In this embodiment, since the mobile phone is used without using the IC card 7, it is not necessary to carry the IC card 7 and the IC card 7 is not lost or stolen. In addition, since the mobile phone that is likely to be always carried is used, the unlocking operation of the delivery box 2 can be performed at any time, which is convenient.
