  FIG. 5 shows an example of the digital watermark correspondence table 50 and the NFC tag correspondence table 60. The data of the digital watermark correspondence table 50 and the NFC tag correspondence table 60 shown in FIG. 5 are stored in the storage unit 42 of the server 4. Various kinds of electronic contents are also stored in the storage unit 42 of the server 4.

  As shown in FIG. 5A, the digital watermark correspondence table 50 includes data items such as digital watermark access information 51 and electronic content URL 52. The digital watermark access information 51 is information for accessing electronic content using a digital watermark. The electronic content URL 52 is a URL indicating a storage location of the electronic content.

  In the example shown in FIG. 5A, the digital watermark access information 51 is an identifier (character string of one alphabet and four digits) that uniquely identifies electronic content. Since the digital watermark has a small amount of data that can be embedded, it is preferable to use a short character string as shown in FIG. 5A instead of a long character string such as a URL.

  When the electronic watermark access information 51 is not a URL, the mobile terminal 3 stores a URL (for example, http://xyz.jp) that identifies the access destination server 4 in the storage unit 32 in advance. Then, the mobile terminal 3 accesses the server 4 by adding the electronic watermark access information 51 as a parameter to the stored URL.

  As shown in FIG. 5B, the NFC tag correspondence table 60 includes data items such as NFC tag access information 61 and an electronic content URL 62. The NFC tag access information 61 is information for accessing electronic content using an NFC tag. The electronic content URL 62 is the same as the electronic content URL 52.

  In the example shown in FIG. 5B, the NFC tag access information 61 includes an identifier (a three-digit number) that uniquely identifies the electronic content in the URL “http://xyz.jp” that identifies the server 4 to be accessed. Is added as a parameter. As described above, in the process using the NFC tag described later (see FIG. 8), the NFC tag detection process and the reading process are realized by the function of the OS. Since the OS cannot refer to the URL specifying the access destination server 4 stored in the storage unit 32 of the portable terminal 3 (because the function of the OS cannot be changed by the application vendor), the NFC tag It is desirable to store the URL in the OS and have the OS read it directly. Note that the storable capacity of the NFC tag is larger than the embeddable capacity of the digital watermark, and the NFC tag can be stored sufficiently if it is a character string of about URL.

  In the example shown in FIG. 5, the digital watermark access information 51 and the NFC tag access information 61 are associated with the electronic content URL 52 in separate tables. This makes it possible to separate the electronic content associated with the digital watermark and the electronic content associated with the NFC tag. Therefore, even with the same printed matter 2, different electronic contents can be displayed with the digital watermark and the NFC tag.

  FIG. 6 is a diagram illustrating an example of the unified correspondence table 70. The example shown in FIG. 6 is a modification of the example shown in FIG. The data of the unified correspondence table 70 illustrated in FIG. 6 is stored in the storage unit 42 of the server 4.

  As shown in FIG. 6, the unified correspondence table 70 has data items such as digital watermark access information 71, NFC tag access information 72, and electronic content URL 73. The digital watermark access information 71 is the same as the digital watermark access information 51. The NFC tag access information 72 is the same as the NFC tag access information 61. The electronic content URL 73 is the same as the electronic content URLs 52 and 62.

  In the example shown in FIG. 6, the digital watermark access information 71 and the NFC tag access information 72 are associated with the electronic content URL 73 in the same table. This makes it possible to unify the electronic content associated with the digital watermark and the electronic content associated with the NFC tag. Therefore, the same electronic content can be displayed with the digital watermark and the NFC tag on the same printed matter 2.

  In the following description, it is assumed that the server 4 stores data of the digital watermark correspondence table 50 and the NFC tag correspondence table 60 shown in FIG. 5A is embedded as the image recognition information 21 of the printed material 2, and the NFC tag access information 61 is embedded in the short-range wireless communication medium 22 attached to the printed material 2. The description will be made assuming that it is stored.

  FIG. 7 is a flowchart showing a flow of processing using a digital watermark. In FIG. 7, first, the consumer operates the mobile terminal 3 to instruct activation of a dedicated application in the implementation of the present invention.

  The control part 31 of the portable terminal 3 will start a dedicated application, if the instruction | indication of starting of a dedicated application is received from a consumer (S11). When the dedicated application is activated, the control unit 31 controls the camera 36 and inputs imaging data (S12). When detecting that the digital watermark is included in the imaging data, the control unit 31 decrypts the encrypted data and acquires the digital watermark access information 51 (S13). And the control part 31 adds the access information 51 for electronic watermarks as a parameter to URL (for example, http://xyz.jp) which identifies the server 4 of the access destination memorize | stored beforehand in the memory | storage part 32, The server 4 is accessed by HTTP communication (S14).

  Next, the control unit 41 of the server 4 extracts the electronic watermark access information 51 (S15), searches the electronic watermark correspondence table 50 (S16), and specifies the electronic content URL 52. And the control part 41 delivers an electronic content to the portable terminal 3 (S17).

  Next, the control unit 31 of the mobile terminal 3 receives the electronic content from the server 4 (S18) and displays the electronic content (S19).

  In this way, the consumer can easily access the electronic content from the printed matter 2 by operating his / her portable terminal 3.

  FIG. 8 is a flowchart showing the flow of processing using an NFC tag. In FIG. 8, first, the consumer holds the portable terminal 3 over the printed material 2.

  When the NFC chip 37 detects the NFC tag (S21), the control unit 31 of the portable terminal 3 instructs the NFC chip 37 to read the data of the NFC tag and acquires the NFC tag access information 61 (S22). And the control part 31 accesses the server 4 by HTTP communication using URL which identifies the server 4 of the access destination which the access information 61 for NFC tags shows (S23). Here, the controller 31 assigns an identifier for uniquely identifying the electronic content as a parameter when performing HTTP communication.

  Next, the control unit 41 of the server 4 extracts the NFC tag access information 61 (S24), searches the NFC tag correspondence table 60 (S25), and specifies the electronic content URL 62. And the control part 41 delivers an electronic content to the portable terminal 3 (S26).

  Next, the control unit 31 of the mobile terminal 3 receives the electronic content from the server 4 (S27) and displays the electronic content (S28).

  In this way, the consumer can easily access the electronic content from the printed matter 2 by operating his / her portable terminal 3.

  As described above, according to the electronic content access support system in the embodiment of the present invention, a consumer can easily access electronic content from a printed matter by operating his / her portable terminal. In particular, it provides two access methods using image recognition information (for example, digital watermark) and access method using a short-range wireless communication medium (for example, NFC tag), so that consumers can access to their mobile terminals. A method can be selected. For example, in the case where the mobile terminal has an NFC chip, an access method using an NFC tag may be selected. On the other hand, when the mobile terminal does not have an NFC chip, an access method using digital watermark may be selected.

  Compared to a two-dimensional barcode, image recognition information (for example, digital watermark) and short-range wireless communication medium (for example, an NFC tag) are easier to operate (a dual barcode is difficult to focus), It is excellent in environmental properties (accuracy decreases depending on the brightness of surroundings in a two-dimensional barcode), stain resistance, and the like. In addition, the image recognition information (for example, digital watermark) and the short-range wireless communication medium (for example, NFC tag) can individually set and change the URL indicating the storage location of the electronic content. Further, the image recognition information (for example, digital watermark) and the short-range wireless communication medium (for example, NFC tag) do not impair the original beauty of the printed material. Furthermore, if the NFC tag is used, a similar service can be developed overseas.

  The preferred embodiments of the electronic content access support system and the like according to the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these naturally belong to the technical scope of the present invention.
