  The pattern determination unit 11, the decoding unit 12, the authentication necessity determination unit 14, the authentication processing unit 17, and the display control unit 15 are stored in the memory 13 by a central processing unit (not shown) of a mobile terminal, for example. The portable terminal is realized by executing the two-dimensional code reading program. Further, the two-dimensional code reading program may be stored in the memory 13 via, for example, a computer-readable recording medium or a transmission medium such as an electronic communication line.

  The CCD 10 has a plurality of light receiving elements arranged in a two-dimensional matrix, and outputs luminance distribution data based on the arrangement of the plurality of light receiving elements and the light receiving luminance.

  The memory 13 stores data. The memory 13 may be fixedly built in the mobile terminal or may be detachably connected to the mobile terminal.

  The input key 18 has a key such as a numeric keypad. And the input data according to a user's key operation is output.

  The liquid crystal display device 16 has a plurality of light emitting elements arranged in a two-dimensional matrix. When display data is input, the plurality of light emitting elements emit light based on the two-dimensional arrangement.

  The pattern determination unit 11 determines whether the luminance distribution data from the CCD 10 includes a two-dimensional code pattern. If the two-dimensional code pattern is included, the pattern determination unit 11 converts the two-dimensional code pattern into the luminance distribution. Extract from the data.

  The decoding unit 12 decodes the two-dimensional code pattern extracted by the pattern determination unit 11 and reproduces the data string encoded in the two-dimensional code pattern. Further, the decoding unit 12 stores the reproduced data string in the memory 13.

  The authentication necessity determination unit 14 extracts the authentication necessity instruction data from the data string input from the decoding unit 12 in accordance with the agreement determined at the time of encoding, and requires authentication based on the value of the authentication necessity instruction data. Determine no.

  The authentication processing unit 17 is stored in the memory 13 together with the input data input from the input key 18 and the two-dimensional code reading program when the authentication necessity determination unit 14 determines that the access permission by the authentication processing is necessary. When the input data that matches the password is input, it is determined as approval.

  In response to an instruction from the authentication necessity determination unit 14 or the authentication processing unit 17, the display control unit 15 reads a data string from the memory 13 and generates display data including text data included in the data string. Further, the display control unit 15 outputs this display data to the liquid crystal display device 16.

  Next, the operation when the authentication-needed two-dimensional code pattern 2 and the authentication-needed two-dimensional code pattern 3 printed on the printed matter in FIG. 1 are read by the portable terminal in FIG. 2 will be described.

  When the CCD 10 of the portable terminal images the two-dimensional code pattern 2 that does not require authentication, the pattern determination unit 11 determines that the two-dimensional code pattern 2 is included based on the luminance distribution data of the CCD 10, and the two-dimensional code Pattern 2 is extracted from the luminance distribution data. In addition, the decoding unit 12 decodes the authentication unnecessary two-dimensional code pattern 2, reproduces the data string encoded in the authentication unnecessary two-dimensional code pattern 2, and stores the data string in the memory 13.

  When the decoding unit 12 reproduces the data string, the authentication necessity determination unit 14 extracts the authentication necessity instruction data from the data string, and determines the necessity of authentication based on the value of the authentication necessity instruction data. To do. The authentication necessity instruction data of the authentication unnecessary two-dimensional code pattern 2 has a value indicating that the authentication processing is unnecessary. Therefore, the authentication necessity determination unit 14 determines that the authentication process is unnecessary, and instructs the display control unit 15 to display the data string. The display control unit 15 reads a data string from the memory 13 in response to an instruction from the authentication necessity determination unit 14, generates display data including text data included in the data string, and the liquid crystal display device 16 Display the display data. As a result, the text of the natural grass encoded in the authentication unnecessary two-dimensional code pattern 2 is displayed on the liquid crystal display device 16.

  Next, when the CCD 10 of the portable terminal images the two-dimensional code pattern 3, the pattern determination unit 11 determines that the two-dimensional code pattern 3 is included based on the luminance distribution data of the CCD 10, and the two-dimensional The code pattern 3 is extracted from the luminance distribution data. The decoding unit 12 decodes the two-dimensional code pattern 3 requiring authentication, reproduces the data string encoded in the two-dimensional code pattern 3 that requires authentication, and stores the data string in the memory 13.

  When the decoding unit 12 reproduces the data string, the authentication necessity determination unit 14 extracts the authentication necessity instruction data from the data string, and determines whether the authentication process is necessary based on the value of the authentication necessity instruction data. judge. The authentication necessity instruction data of the authentication required two-dimensional code pattern 3 has a value indicating that access permission by the authentication process is necessary. Therefore, the authentication necessity determination unit 14 determines that access permission by the authentication process is necessary, and instructs the authentication processing unit 17 to execute the authentication process.

  The authentication processing unit 17 compares the input data input from the input key 18 with the password stored in the memory 13, and when input data that matches the password is input, the access to the data is permitted. The display control unit 15 is instructed to display the data string. The password may be stored in advance in the memory 13 or may be stored as data in the two-dimensional code pattern 3. In response to an instruction from the authentication processing unit 17, the display control unit 15 reads a data string from the memory 13, generates display data including text data included in the data string, and the liquid crystal display device 16 Display data. As a result, the annotations and explanations of natural grass encoded in the two-dimensional code pattern 3 requiring authentication are displayed on the liquid crystal display device 16.

  As described above, on a printed matter such as the book 1 according to the first embodiment, two two-dimensional code patterns of the authentication-required two-dimensional code pattern 3 and the authentication-unnecessary two-dimensional code pattern 2 are printed on each page. doing. The authentication-needed two-dimensional code pattern 2 includes a data string including text data of the natural text printed in the upper part of each page and authentication necessity instruction data having a value indicating that the authentication process is unnecessary. Is stored in the authentication-required two-dimensional code pattern 3, and the text data of the annotations and explanations of the natural grass printed at the bottom of each page and the value indicating that access permission by the authentication process is required A data string including instruction data is stored.

  In addition, the portable terminal according to the first embodiment reproduces a data sequence encoded in the two-dimensional code pattern from the CCD 10 that images the two-dimensional code pattern and the two-dimensional code pattern imaged by the CCD 10. When the decoding unit 12, the authentication processing unit 17 that performs authentication processing, and text data are input, the liquid crystal display device 16 that displays the text data and the text data included in the reproduced data string are displayed for display. When access permission by the authentication process is required, the text data is output to the liquid crystal display device 16 after the authentication process of the authentication processing unit 17, and the text data included in the reproduced data string does not require the authentication process for the display. If it is, the text data is output to the liquid crystal display device 16 without passing through the authentication processing of the authentication processing unit 17. Having, a display control unit 15. In particular, the display control unit 15 includes the authentication processing unit 17 when the data string reproduced by the decoding unit 12 includes authentication necessity instruction data indicating that access permission by the authentication processing is necessary. The text data included in the data string is output to the liquid crystal display device 16 after the access is permitted by the authentication process, and the data string reproduced by the decoding unit 12 includes authentication necessity indication data indicating that the authentication process is unnecessary. If it is included, the text data included in the data string is output to the liquid crystal display device 16 without the authentication processing of the authentication processing unit 17.

  Therefore, according to the first embodiment, these texts printed on each page of the book 1 can be easily provided without providing a database for storing the text of natural grass to be printed on each page of the book 1 or its annotations and explanations. Text data of sentences can be provided by a two-dimensional code pattern printed on the paper. As a result, the user of the printed material does not need to make a hard copy of the printed material. Further, the user of the printed material can easily obtain accurate and error-free text data without re-inputting the text of the printed material by himself / herself.

  In addition, the text to be printed on each page of the book 1 or the explanation related to the text is encoded with text data that can be displayed on the liquid crystal display device 16 only when access is permitted by the authentication process. The dimensional code pattern 3 and the authentication-required two-dimensional code pattern 2 in which text data that can be displayed on the liquid crystal display device 16 without being subjected to an authentication process are encoded. Therefore, the use of data can be managed by the authentication process. Thus, specific data can be provided only to those who have access rights, and data can be provided appropriately.

  In the first embodiment, when access permission is required to display text data encoded in a two-dimensional code pattern, the authentication processing unit 17 receives input data input from the input key 18. And the password stored in advance in the memory 13 together with the two-dimensional code reading program for authentication. Thereby, the authority of the user who uses the two two-dimensional code patterns 2 and 3 can be managed by distinguishing between a person who simply reads the printed material and a person who uses the text written on the printed material.

  Note that the password input at the time of authentication may be printed on a scratch card, a seal, a receipt, or the like different from the printed material and sold at a bookstore. In particular, in the case of a scratch card, a seal, and a receipt, it is not necessary to give the user the trouble of obtaining a password or the like by giving it when the book 1 is purchased. Also, instead of inputting the password with the input key 18, the password is transmitted from the infrared communication device installed in the bookstore or the like to the infrared port of the portable terminal, or the communication of the purchaser's portable terminal from the server on the wireless communication or the Internet. The password may be input by transmitting the password to the department. In this case, the authentication processing unit 17 performs authentication by comparing the transmitted password with a password stored in advance in the memory 13. By providing the password separately from the printed material in this way, it is possible to provide a password common to a plurality of printed materials, change the password for each printed material, or change the password every predetermined period. When the password changes, the password to be verified and the two-dimensional code reading program need to be changed as necessary. Further, this password may be attached as a separate two-dimensional code pattern to a specific place such as a cover of printed matter.

  In addition, when a password is transmitted from an infrared communication device or server to a mobile terminal in this way, the mobile terminal transmits an infrared communication with a number unique to the mobile terminal (for example, a telephone number if it is a mobile phone terminal) at the time of purchase. After registering to the device or server, after that, the infrared communication device or server compares the unique number transmitted from the mobile terminal with this pre-registered number, and if they match, the purchase process The password can be reissued by configuring so that the password is transmitted again to the portable terminal without having to perform the process.

  Further, the password to be compared with the input or transmitted password may be distributed together with the two-dimensional code reading program and not stored in the memory 13 in advance. For example, the password to be verified may be encoded and stored in the authentication required two-dimensional code pattern 3 together with authentication necessity instruction data having a value indicating that access permission is required. Further, the value itself of the authentication necessity instruction data may be used as a password to be verified. Thus, by storing the password to be verified in the two-dimensional code pattern 3 that requires authentication, one two-dimensional code reading program can be used for a plurality of two-dimensional code patterns 3 that require different passwords to be verified. Can be used in common. In addition, when the value itself of the authentication necessity instruction data is a verification password for a plurality of two-dimensional code patterns 3 that require different passwords, a common value is used to indicate that no authentication process is required between them. As one value, the authentication necessity determination unit 14 does not require authentication processing when the value of the authentication necessity instruction data indicates that authentication is not required, and always authenticates in other cases. It may be determined that access permission by is necessary.

  In the first embodiment, the printed material is described using the book 1 as an example. However, the printed material can be suitably used for printed materials such as intermediate prints of newspapers and trains, posters, newspapers, and tickets.

  FIG. 4 is a block diagram showing a mobile terminal according to Embodiment 2 of the present invention.

  The portable terminal includes a CCD 10, a pattern determination unit 11, a decoding unit 12, an authentication necessity determination unit 14, an authentication decoding unit 20 as an authentication unit, a display control unit 15, a liquid crystal display device 16, and a memory 13. And an infrared port 21. The pattern determination unit 11, the decoding unit 12, the authentication necessity determination unit 14, the authentication decoding unit 20, and the display control unit 15 are stored in the memory 13 by, for example, a central processing unit (not shown) of a mobile terminal. The portable terminal is realized by executing the two-dimensional code reading program. The two-dimensional code reading program may be stored in the memory 13 via a computer-readable recording medium or a transmission medium such as an electronic communication line. Components having the same functions as those in the first embodiment are denoted by the same reference numerals as those of the components having the same names in the first embodiment, and description thereof is omitted.

  The infrared port 21 has a light receiving element that receives infrared rays. And the light reception data according to the infrared intensity pattern which the light receiving element received is output.

  The authentication decryption unit 20 is executed when the authentication necessity determination unit 14 determines that access permission by the authentication process is necessary. The authentication decryption unit 20 then decrypts the decoded data string stored in the memory 13 with the encryption key stored in the memory 13 using the received light data output from the infrared port 21 as the decryption key. The decrypted data string is stored in the memory 13. The decoded data string may be stored by overwriting the decoded data string stored in the memory 13 or may be stored separately from the decoded data string.

  Next, the operation when the authentication-needed two-dimensional code pattern 6 and the authentication-needed two-dimensional code pattern 5 printed on the printed material of FIG. 3 are read by the portable terminal of FIG. 4 will be described.

  When the CCD 10 of the portable terminal images the two-dimensional code pattern 6, the pattern determination unit 11 extracts the two-dimensional code pattern 6 from the luminance distribution data of the CCD 10, and the decoding unit 12 decodes the two-dimensional code pattern 6. The reproduced data string is stored in the memory 13. Further, the authentication necessity determination unit 14 determines that the authentication process is unnecessary based on the value of the authentication necessity instruction data of the reproduced data string, and instructs the display control unit 15 to display the data string. . The display control unit 15 reads a data string from the memory 13 in response to an instruction from the authentication necessity determination unit 14, generates display data including text data included in the data string, and displays it on the liquid crystal display device 16. Let Thereby, the printed property information encoded in the two-dimensional code pattern 6 that does not require authentication is displayed on the liquid crystal display device 16.

  Next, when the CCD 10 of the portable terminal causes the two-dimensional code pattern 5 to be imaged, the pattern determination unit 11 extracts the two-dimensional code pattern 5 from the luminance distribution data of the CCD 10, and the decoding unit 12 extracts the two-dimensional code pattern 5. A data string reproduced by decoding is stored in the memory 13. Further, the authentication necessity determination unit 14 determines that access permission by the authentication process is necessary based on the value of the authentication necessity instruction data of the reproduced data string, and causes the authentication decryption unit 20 to execute the authentication process. Instructing the execution of the decoding process.

  The authentication decryption unit 20 decrypts the decoded text data stored in the memory 13 using the received light data output from the infrared port 21 as a decryption key (encryption key), and stores the decrypted text data in the memory 13. Remember me. Thereafter, the authentication decryption unit 20 instructs the display control unit 15 to display text data. The display control unit 15 reads the decrypted text data from the memory 13 in accordance with an instruction from the authentication processing unit, and displays it on the liquid crystal display device 16. Thereby, the liquid crystal display device 16 displays all addresses and telephone numbers of the house or its contact information encoded in the two-dimensional code pattern 5 requiring authentication. Thereby, the user can know the detailed address and contact information of a house.

  If the received light data received by the infrared port 21 does not match the correct decryption key, the encrypted text data cannot be decrypted into the correct text data. Therefore, an unknown text is displayed on the liquid crystal display device 16. Alternatively, a predetermined identifier may be included in the text data, and it may be determined whether or not the identifier is correctly decoded based on whether or not the identifier is correctly decoded after decoding. In that case, if the data is not correctly decoded, the data display is prohibited.

  As described above, in the second embodiment, the text data that can be displayed on the liquid crystal display device 16 without undergoing the authentication process is printed on the paper surface on which the authentication-required two-dimensional code pattern 5 that is obtained by encoding the data is printed. The text data of the property information that is printed and that can be displayed on the liquid crystal display device 16 only when access is permitted by the authentication process is the address or address of the house or contact address for the property information. Includes text data of telephone numbers. Therefore, the text data of the property information printed on the paper can be provided without authentication by the two-dimensional code pattern 6 that does not require authentication printed on the same paper, and the housing or the contact concerning the property information can be provided. The text data of the previous address and telephone number can be provided after being authenticated by the authentication-required two-dimensional code pattern 5 printed on the same sheet.

  In particular, as in the second embodiment, the address or telephone number of the house or contact information that is important additional information about the property is provided only by the two-dimensional code pattern 5 that requires authentication, and is not printed on paper. Thus, so-called digital shoplifting using a mobile phone terminal with a camera, a digital camera, or the like (taking information only with a camera and stealing it without purchasing a book 4 such as an information magazine) can be effectively suppressed. .

  Further, in the second embodiment, the text data of the address or telephone number of the house or contact address related to the property information that can be displayed on the liquid crystal display device 16 only when access is permitted by the authentication process is encrypted. Above, it is encoded in the two-dimensional code pattern 5 that requires authentication. Therefore, the text data that can be displayed on the liquid crystal display device 16 only when access is permitted by the authentication process is in an encrypted state simply by being decoded. Therefore, this text data cannot be used without being authenticated. If authentication is required to display text data encoded in the two-dimensional code pattern, the authentication decryption unit 20 is encrypted using the received light data input from the infrared port 21. The text data is decrypted. Accordingly, it is possible to manage a user who uses a two-dimensional code pattern by distinguishing between a person who simply reads the printed material and a person who wants to know additional information described in the printed material.

  In the second embodiment, the authentication decryption unit 20 uses the transmitted authentication data as a decryption key, and the liquid crystal display device 16 only when access is permitted by the authentication process from the data string reproduced by the decoding unit 12. Decodes text data that can be displayed in Accordingly, authentication processing is realized by encryption, and even if the reading device is illegally modified, it is difficult to illegally obtain the output data of that portion.

  In the second embodiment, the printed matter is described using a housing information magazine as an example. However, the printed matter is preferably used for other printed matters such as books, newspapers, trains, and other intermediate prints, posters, newspapers, and tickets. Can do. The additional information related to the printed text includes, for example, additional explanations such as explanations of terms for newspaper articles, other additional explanations, explanations of contents for headlines in a suspended advertisement such as a train, and the like.

A data string reproduced by decoding is stored in the memory 13.

  The data string division storage unit 31 receives the data string reproduced by the decoding unit 12. Then, the data string division storage unit 31 divides the reproduced data string into an authentication unnecessary data string and an authentication required data string and stores them in the memory 13. Specifically, for example, the data string division storage unit 31 uses the authentication necessity indication data having a value indicating that the authentication process is unnecessary, and the authentication having the value indicating that the access permission by the authentication process is necessary. Data up to immediately before the necessity instruction data is divided into an authentication unnecessary data string, and the subsequent data is divided as an authentication necessary data string. As a result, the authentication unnecessary data string includes the authentication necessity instruction data having a value indicating that the authentication process is unnecessary and the text data of the question sentence. The authentication required data string includes authentication necessity instruction data having a value indicating that authentication is required, and data obtained by encrypting text data of answers and explanations.

  Further, the authentication processing unit 33 compares the input data input from the input key 18 with the password stored in advance in the memory 13 together with the two-dimensional code reading program, and the decryption unit 32 determines that the access permission determination result is If stored in the memory 13, the encrypted text data included in the authentication-required data string is decrypted, and the decrypted text data and the decryption completion flag are stored in the memory 13.
