  [Description of Operation] Next, the operation of the color code utilization system 1 in this embodiment will be described. FIG. 7 is a flowchart of the code authenticity determination process in the present embodiment.

  The code authenticity determination process is started when the authenticity determination apparatus 100 receives video information including one or more color codes.

  In the code authenticity determination process, the authenticity determination device 100 identifies the color code and the accompanying information included in the video information, and if the related information associated in advance with the color code corresponds to the accompanying information, The color code is determined to be authentic.

  First, the video reception unit 111 receives a video in which a color code is reflected (step S001). Then, the code reading unit 112 specifies a color code (step S002). Specifically, the code reading unit 112 detects the presence of the color code and detects the position in the video by pattern matching the shape, arrangement, etc. of the graphic characteristic of the color code from the received video information. One or a plurality of codes are read by specifying and specifying the reading direction. Although not shown, the code reading unit 112 indicates that the specified color code is within the expiration date 121C, is not invalidated by the invalid information 121D, and is affixed by the pasting target information 121B. It is also determined whether or not the object corresponds to the reading object 300. If any of the objects is negative, the code authenticity determination process is terminated.

  And the authenticity determination part 114 reads the kind of related information (step S003). Specifically, the authenticity determination unit 114 reads the related information type 122B associated with the management code 122A related to the color code specified in step S002 from the related information storage unit 122B.

  And the authenticity determination part 114 determines whether relevant information is required (step S004). Specifically, the authenticity determination unit 114 determines that the related information is required if any related information type is stored in the related information type 122B, and if not, stores the related information. Judge that it is not necessary. If it is determined that the related information is not required, the authenticity determination unit 114 advances the control to step S006.

  When related information is required (in the case of “Yes” in step S004), the authenticity determination unit 114 determines whether or not the received video is associated with information that matches the related information (step S005). . Here, “matches with related information” means that the incidental information acquisition unit 113 acquires incidental information with the same type of associated information from the video information, and the incidental information and the associated information 122C match or is predetermined. To be within the range of. The incidental information may include information (for example, size, height, depth, width, uneven shape, etc.) indicating the shape of the reading object 300 that is the object provided with the color code 350. Further, for example, the supplementary information may include information for specifying a distance to a subject reflected in a plurality of predetermined pixels on the video information, or information for specifying a person reflected on the video information. Alternatively, it may be information for specifying a feature point of the shape of a person's face reflected on the video information. Alternatively, the incidental information may be information specifying one or more other code information reflected on the video information.

  When information that matches the related information is associated with the received video (in the case of “Yes” in step S005), the authenticity determination unit 114 returns display information indicating the determination result “true” along with the code ( Step S006). The browser unit 212 that has received the display information displays the display information. Then, the authenticity determination unit 114 ends the code authenticity determination process.

  When the received video is not associated with information that matches the related information (in the case of “No” in step S005), the authenticity determination unit 114 returns display information indicating the determination result “贋” along with the code ( Step S007). The browser unit 212 that has received the display information displays the display information. Then, the authenticity determination unit 114 ends the code authenticity determination process.

  The above is the process flow of the code authenticity determination process according to the first embodiment. According to the authenticity determination process, regarding video information including a color code and incidental information, if the related information previously associated with the color code corresponds to the incidental information, the color code is regarded as authentic. Can be determined.

The result display screen 600 includes a management code 611, a reading position 612, a reading date and time 613, a reading operator 614, a message 610, a read video display area 620, a reread instruction reception button 630, a reading A stop instruction receiving button 640. In the message 610 of the result display screen 600, for example, when the incidental information of the video is different from the related information associated in advance, a message such as “Code reading is not valid. Please perform correct reading.” Is displayed, suggesting that the code may not be authentic, and can be prompted to reread.

  The management code 611 is an area for displaying a code obtained as a result of decoding the color code 350 included in the video information obtained by imaging. If the color code is not authentic, the code obtained as a result of the decoding should not be adopted, and another character string such as “cannot be displayed” is displayed as the management code 611.

  The reading position 612 is an area for displaying information for specifying the position where the reading terminal 200 exists at the time of imaging. For example, it may be information specifying a range having a predetermined spatial extent, such as a coordinate position acquired from GPS or an SSID display of the nearest wireless LAN access point.

  The reading date and time 613 is an area for displaying information for specifying the time of imaging. For example, it is information on the time when the image was taken, which is incidental to the video information.

  The reading worker 614 is an area for displaying information for identifying the photographer. For example, it is exif copyright information incidental to video information.

  Video information captured by the imaging control unit 211 of the reading terminal 200 is displayed in the read video display area 620. The video includes a reading target 620B, a color code 620A, and an arrangement near view 620C.

  When the rereading instruction acceptance button 630 accepts an input, the video is reacquired and the code authenticity determination process is started again.

  When accepting an input, the reading stop instruction acceptance button 640 terminates the code authenticity determination process and ends the screen so that the code authenticity determination process cannot be executed.

  The above is an output example of the result display screen 600 according to the first embodiment.

  The above is the color code utilization system 1 which concerns on 1st embodiment. According to the first embodiment, it is possible to easily determine the authenticity of a color code using the color code 350 attached to the reading object 300 and the accompanying information.

  The present invention is not limited to the first embodiment described above. The first embodiment described above can be variously modified within the scope of the technical idea of the present invention. For example, in the first embodiment described above, there is one related information associated with the management code, but the present invention is not limited to this. For example, a plurality of related information may be used so that higher authenticity can be determined. Such a second embodiment will be described below. Note that the second embodiment basically has the same configuration as that described in the first embodiment, but there are some differences, and thus the differences will be mainly described.

  A second embodiment will be described with reference to FIGS. 9 and 10. FIG. 9 is a diagram illustrating a configuration example of the related information storage unit 122 ′ according to the second embodiment. The related information storage unit 122 ′ is similar to the first embodiment in that the management code 122A, the related information type 122B, and the related information 122C are associated with each other. However, in the second embodiment, the related information associated with the management code 122A can be further associated with the sub-related information. Specifically, the sub-related information is associated with the management code 122A. One or more information types 122E, sub-related information 122F, and guidance control 122G are associated with each other.

  The sub-related information type 122E is information that specifies the type of information used to prove the authenticity of the color code 350. For example, the sub-related information type 122E has one relationship selected from among the coordinates indicating the position information, the distance information to the subject, or the date and time of imaging that excludes the type designated as the related information type 122B. Indicates the type of information.

  The sub-related information 122F is information used to prove the authenticity of the color code 350. For example, the sub-related information 122F is information predetermined for the sub-related information type 122E, such as coordinates indicating a position, a distance to a subject, or an imaging date and time.

  The guidance control 122G is a program that guides an imaging method such as an imaging position and an imaging range, for example, when the related information is matched but the sub-related information is not matched. As an example of such guidance control 122G, for example, the imaging control unit 211 of the reading terminal 200 is guided to fix the focus distance to a predetermined distance so that the in-focus position is the correct imaging position. including. Also, for example, when the distance to the subject is the main related information and the GPS position information is the sub related information, if the distance to the subject is correct but the GPS position is slightly different, the guidance is given so that the correct GPS position is obtained. Including doing. That is, by using the guidance control 122G, it is possible to perform guidance by performing control on how to use an external device that acquires video.

  FIG. 10 is a flowchart of the code authenticity determination process according to the second embodiment. The code authenticity determination process according to the second embodiment is basically the same as the code authenticity determination process according to the first embodiment, with the same reference numerals as those in FIG. 7 being used. Differences will be described below.

  In the code authenticity determination processing according to the second embodiment, when related information is required in step S004, the authenticity determination unit 114 determines whether information that matches all the related information is associated with the received video. Is determined (step S105).

  If the received video is not associated with information that matches all the related information, the authenticity determination unit 114 determines whether only the sub related information is insufficiently matched (step S107). If there is no shortage of information only (if “No” in step S107), control proceeds to step S007.

  If only the sub-related information is insufficient (“Yes” in step S107), guidance is performed using the guidance control 122G associated with the insufficient sub-related information (step S108). Then, control is returned to the head of the code authenticity determination process.

  The above is the color code utilization system 1 according to the second embodiment. According to the second embodiment, it is possible to easily determine the authenticity of a color code with high accuracy by using the supplementary information as a subordinate to see a match.

  The present invention is not limited to the first and second embodiments described above. For example, in the first embodiment, the color code is treated as a management code corresponding to the color code on a one-to-one basis when the incidental information matches the predetermined associated information, and the incidental information is associated information. If it does not match, it can be said that it is not treated as a management code, but it is not limited to this. Such a third embodiment will be described below. Note that the third embodiment basically includes the same configuration as that described in the first embodiment, but there are some differences, and thus the differences will be mainly described.

  FIG. 11 is a diagram illustrating a configuration example of the related information storage unit 122 ″ in the third embodiment. In the related information storage unit 122 ″, a reading rule 122 D indicating a rule for specifying which digit of the color code is read as valid information is added to the related information storage unit 122. Note that the reading rule 122D may be information for specifying a digit handled as dummy information in the color code.

  FIG. 12 is a diagram illustrating a code authenticity determination process in the third embodiment. The code authenticity determination process in the third embodiment is basically the same as the code authenticity determination process in the first and second embodiments with the same reference numerals as those in FIGS.

  In step S004, when related information is required, the authenticity determination unit 114 determines whether or not the received video is associated with information that matches all the related information (step S205). If information that matches all the related information is associated (in the case of “Yes” in step S205), the code reading unit 112 rereads the color code according to the rule if there is a reading rule. (Step S206). Then, the authenticity determination unit 114 returns the determination result “true” together with the information of the color code obtained as a result of the re-reading (step S210). Then, the authenticity determination unit 114 ends the code authenticity determination process.

  The above is the process flow of the code authenticity determination process according to the third embodiment. According to the code authenticity determination processing according to the third embodiment, since the incidental information does not match the related information, the color code read without following the reading rule is information different from the management code, and thus significant management is performed. In order to obtain the code, it is necessary to acquire the video so that the incidental information matches the related information, and it is possible to secure higher security and to easily prevent forgery of the color code.

  The present invention is not limited to the first to third embodiments described above. For example, in the first embodiment, the color code is treated as a management code corresponding to the color code on a one-to-one basis when the incidental information matches the predetermined associated information, and the incidental information is associated information. If it does not match, it can be said that it is not treated as a management code, but it is not limited to this. Such a third embodiment will be described below. In the third embodiment, the configuration with the same reference numerals as in FIG. 1 is basically the same as the configuration described in the first embodiment, but there are some differences. The difference will be mainly described.

  FIG. 13 is a diagram illustrating a configuration example of the color code utilization system 1 according to the fourth embodiment. Regarding the fourth embodiment, the configuration given the same reference numerals as in FIG. 1 has basically the same configuration as the first embodiment, but there are some differences. Hereinafter, the difference will be mainly described.

  The reading terminal 200 is basically the same as the reading terminal 200 according to the first embodiment, but the control unit 210 is provided with a code reading unit 215 instead of the satellite wave control unit 213. In addition, a storage unit 240 implemented by a nonvolatile storage device such as a hard disk or an SSD is provided, and the decryption key storage unit 241 is stored in the storage unit 240.

  The reading terminal 200 can access the premium member server 800 and the general member server 810 via the network 10. For example, when there is a predetermined service that requests payment of a predetermined price for enjoyment of the service, the premium member server 800 is a server that performs information processing for realizing the service. The general member server 810 is a server that performs information processing for realizing a predetermined service that does not require payment of a predetermined price for the enjoyment of the service, for example. The difference between the premium member server 800 and the general member server 810 naturally includes, for example, cases where the types of services are different. However, when the quality and quantity of services are different, they are divided according to the amount paid for the members. May be used.

  The code reading unit 215 finds the color code 350 constituting a part of the video included in the video information received by the imaging control unit 211 and reads it as a code. Note that when the video information includes a plurality of color codes, the code reading unit 215 reads the plurality of codes included in the video information. Further, the code reading unit 215 recognizes characters included in a video in the vicinity of the color code (for example, within a predetermined number of pixels based on the outer periphery of the color code) in the video information, and reads it as a series of character strings. .

  FIG. 14 is a diagram illustrating a configuration example of the decryption key storage unit 241 according to the fourth embodiment. In the decryption key storage unit 241, a decryption key 241A that is a decryption key applied to a color code via a predetermined algorithm, and an implicit access obtained by applying the decryption key to the color code via a predetermined algorithm Information 241B is stored in association with each other. For example, the decryption key may be information corresponding to a color filter that converts color information. Specifically, the decryption key may be code information for executing processing for partially replacing RGB channel information for each digit of the color code or mutually in a predetermined direction.

  FIG. 15 is a diagram illustrating a code reading process according to the fourth embodiment. The code reading process in the fourth embodiment is started when the imaging control unit 211 receives an instruction to capture an image by the imaging unit 220.

  In the code reading process, the reading terminal 200 identifies the color code included in the captured video information and the character information in the vicinity of the color code, and decodes the color code included in the captured video information with a predetermined decoding key. When the implied access information obtained in this manner matches the predetermined implied access information, the server, that is, the premium member server 800 is accessed using the implied access information. If it does not match the implicit access information associated with any decryption key, the general member server 810 is accessed using the character string read from the vicinity of the color code as the explicit access information (URL).

  First, the imaging control unit 211 captures an image in which a color code is reflected (step S301).

  Then, the code reading unit 215 specifies a color code (step S302). Specifically, the code reading unit 215 detects the presence of the color code and the video by pattern-matching the shape and arrangement of the graphic characteristic of the color code from the video information obtained as a result of imaging. One or a plurality of codes are read out by specifying the position of the inside and specifying the reading direction.

  Then, the code reading unit 215 specifies the character string in the video as the explicit access information (Step S303). Specifically, the code reading unit 215 recognizes characters included in the video in the vicinity of the color code among the video information represented by the video information captured in step S301, and reads out as a series of character strings.

  Then, the code reading unit 215 reads the decryption key and the implicit access information (Step S304). Specifically, the code reading unit 215 refers to the decryption key storage unit 241 and reads the decryption key 241A and the implicit access information 241B in association with each other.

  The code reading unit 215 determines whether or not there is a decryption key whose decryption result matches with any of the implicit access information (step S305). Specifically, the code reading unit 215 decrypts the color code identified in step S302 with a predetermined algorithm using each of the decryption keys read in step S304, and information obtained as a result of the decryption is obtained. It is determined whether or not the corresponding implicit access information matches, and it is determined whether or not there is a decryption key in which the decryption result information matches the implicit access information.

  If there is no decryption key whose decryption result matches the implicit access information (“No” in step S305), the code reading unit 215 determines whether there is a decryption key whose decryption result matches the explicit access information. Is determined (step S306). Specifically, the code reading unit 215 determines whether each of the results of decryption in step S305 matches the explicit access information specified in step S303, and the decryption keys having a matching relationship The presence or absence of is determined. If there is no decryption key that matches the explicit access information, the code reading unit 215 ends the code reading process.

  If there is a decryption key having a relationship that matches the explicit access information (“Yes” in step S306), the browser unit 212 accesses the general member server 810 using the explicit access information (step S306). S307). Then, the code reading unit 215 ends the code reading process.

  When there is a decryption key whose decryption result matches the implied access information (in the case of “Yes” in step S305), the browser unit 212 accesses the premium member server 800 using the implied access information (step S305). S308). Then, the code reading unit 215 ends the code reading process.

  The above is the process flow of the code reading process according to the fourth embodiment. According to the code reading process according to the fourth embodiment, when access information implied as a result of decryption with the decryption key is obtained, the server is accessed using the implied access information for obtaining a special service. Otherwise, if it is possible to access the server using the access information when the access information that can obtain the normal service is obtained, the normal access is possible even if the color code is decoded. If it is not possible to obtain explicit access information for obtaining a service, it is possible to prevent access to the server. As a result, for example, when the color code is not authentic (when the code is forged or modified), access to the server by reading the color code can be restricted. Therefore, it can be said that the reading terminal 200 according to the fourth embodiment is a color code authenticity determination device. Further, in the fourth embodiment, the authenticity determination device 100 shown in the first embodiment is not clearly shown, but the color is determined via the network 10 prior to the process of specifying the color code in step S302 in FIG. The authenticity determination device 100 may be inquired about the authenticity of the code, and the subsequent process is performed only when the authenticity determination result is true, and the code reading process is terminated when the authenticity determination result is authentic. .

  For example, in the above embodiment, the reading terminal 200 is provided with the imaging unit 220, but the present invention is not limited to this. For example, an optical image acquisition device corresponding to the imaging unit 220 is connected to the reading terminal 200 by wire (USB communication, LAN, etc.) or wirelessly (NFC (Near Field Communication), Bluetooth, wireless LAN, etc.) and imaged. Also good. In this way, for example, it is possible to acquire information on a fixed point camera such as a monitoring camera provided at a place where the reading target 300 is arranged, and to confirm the presence of the reading target 300. Even if it is arranged at a place where a specific number of people go in and out, it is possible to find the theft and replacement, which is useful for theft monitoring.

  Further, for example, in the first embodiment described above, the authenticity determination device 100 and the reading terminal 200 are different devices. For example, the reading terminal has the same configuration as the control unit 110 and the storage unit 120 of the authenticity determination device 100. It is also possible to realize with a single device such as 200.

  Further, the technical elements of the above-described embodiments may be applied independently, or may be applied by being divided into a plurality of parts such as program parts and hardware parts.

  In the above, this invention was demonstrated centering on embodiment.
