  Exemplary embodiments of a two-dimensional code generation program, a two-dimensional code generation system, and a two-dimensional code generation method according to the present invention will be described below in detail with reference to the accompanying drawings. In the following, a QR code is cited as an example of a two-dimensional code, but the present invention can be similarly applied to other two-dimensional codes such as a data matrix and a maxi code.

  First, the concept of QR code generation processing according to the present invention will be described. FIG. 1 is a diagram showing the concept of QR code generation processing according to the present invention. In this QR code generation process, a short URL that is associated with a URL of a predetermined website and is expressed shorter than the URL is generated. Here, the short URL is configured using redirect server address information, property information, expiration date information, and a random number.

  The redirect server address information is information on the address of the redirect server that converts the short URL into the original URL. This redirect server will be described in detail later.

  The property information is information on the type of website corresponding to the URL. Each website is classified into predetermined types such as “gourmet”, “sports”, and “news” depending on the content. This property information is represented by arbitrary three characters (“aaa” in the example of FIG. 1). The expiration date information is information on the expiration date of the short URL (14 days in the example of FIG. 1).

  The random number is a random number generated to identify each short URL (“01234456789ab” in the example of FIG. 1). The first three numbers of this random number (“0”, “1”, “2” in the example of FIG. 1) correspond to predetermined directories formed in the storage device of the redirect server, respectively. Information on the correspondence between the short URL and the original URL is stored in the directory specified by the number.

  The three consecutive numbers “0”, “1”, and “2” in the example of FIG. 1 include a directory corresponding to the number “1” in the directory corresponding to the number “0”, and the number “1”. A directory corresponding to the number “2” is present in the directory corresponding to, and the information corresponding to the short URL and the original URL is stored in the directory corresponding to the number “2”. Yes.

  As described above, by including information on the directory in which the correspondence information is stored in the short URL, the redirect server can easily determine the directory in which the correspondence information is stored. Even when there are about tens of millions, it is possible to search for a URL corresponding to a short URL at high speed.

  After the short URL is generated in this way, a QR code further including the short URL is generated. FIG. 1 shows a QR code including original URL information and a QR code including short URL information generated as described above. It can be seen that the QR code including the short URL information is rougher than the QR code including the original URL information.

  The generated QR code is stored in a server device or the like that provides a website browsing service, and is displayed on the website. Alternatively, the generated QR code is printed on a printed matter such as a newspaper or a magazine so as to be read by a mobile phone.

  Then, when the QR code is read by the mobile phone and the redirect server is accessed using the short URL information included in the QR code, the redirect server converts the short URL into the original URL. The URL information is transmitted to the mobile phone. The mobile phone that has received this information accesses the website corresponding to the URL based on the received URL information.

  As described above, since the QR code including the short URL information is not finer than the QR code including the original URL information, it is necessary to read the QR code with a camera having a small number of pixels. Even when it is necessary to generate a QR code as small as possible, it is possible to prevent the QR code reading success rate from being lowered.

Also, the short URL generation unit 65b acquires the abbreviation information of the acquired property from the property abbreviation data 64b.

  Thereafter, the short URL generation unit 65b generates a 12-character random number, and generates a short URL as shown in FIG. 1 based on the property abbreviation information, the short URL expiration date information, and the random number. .

  Then, the short URL generation unit 65b associates the generated short URL and the generation date of the short URL with the original URL and stores them in the storage unit 64 as the short URL data 64c. The short URL data 64c is transmitted to the QR code generation server 70 by the information management unit 65a, and is stored as short URL data 74c by the QR code generation server 70.

  In addition, the short URL generation unit 65b receives, via the input unit 62, information as to whether or not there is a content such as an image displayed on the designated website that prohibits redistribution. If there is content that is prohibited from being redistributed, the information management unit 65 a transmits information on the content to the QR code generation server 70 via the communication processing unit 61.

  Here, the short URL generation unit 65b generates a short URL corresponding to the URL of the website designated by the user via the input unit 62. However, the short URL generation unit 65b does not generate the web server 30a. , 30b may be received from the web servers 30a, 30b and a short URL corresponding to the URL may be generated.

  The QR code generation server 70 is a server device that generates a QR code including short URL information. The QR code generation server 70 includes a communication processing unit 71, an input unit 72, a display unit 73, a storage unit 74, and a control unit 75.

Further, the short URL generation unit 65b acquires information on the expiration date of the short URL from the URL data 64a (step S103).

  Subsequently, the short URL generation unit 65b generates a 12-character random number (step S104), and generates a short URL based on the property abbreviation information, the short URL expiration date information, and the generated random number. Then, the short URL information is associated with the URL of the website and stored as the short URL data 64c (step S106).

  Thereafter, the QR code generation unit 75b of the QR code generation server 70 acquires the short URL information generated by the short URL generation server 60, and generates a QR code including the acquired short URL information (step S107). ), And stores the generated QR code information as QR code data 74b (step S108).

  Then, the redistribution availability setting unit 75c acquires the information on the presence / absence of image data that sets the non-redistributable identifier received by the short URL generation server 60, and determines whether there is image data that sets the non-redistributable identifier. (Step S109).

  If there is image data for which an unredistributable identifier is set (step S109, Yes), the redistribution permission setting unit 75c reads the image data from the web servers 30a and 30b (step S110), and the read image data An unredistributable identifier is embedded at a predetermined position (step S111).

  Then, the information management unit 75a transmits the image data in which the non-redistributable identifier is embedded to the web servers 30a and 30b in which the original image data is stored (step S112), and the image data is transmitted to the web servers 30a and 30b. Remember me.

  Thereafter, the information management unit 75a transmits the short URL data 74a to the redirect server 50 and also transmits the QR code data 74b to the web servers 30a and 30b (step S113), and ends the QR code generation process.

  Here, the embedding of the non-redistributable identifier into the image data is performed after the generation of the short URL and the QR code, but the embedding of the non-redistributable identifier is performed before the generation of the short URL and the QR code. Also good.
