However, as long as the content data encoded in two dimensions can be read, even copyright-protected content data can be imported into the mobile device (MS) 41 without any copyright fee. End up.
As described above, the content data reading system printed using the two-dimensional code symbol on paper is not a system that can be charged, and can only handle copyright-free content. For this reason, it has been difficult for the mobile device (MS) 41 to spread the two-dimensional code symbol as a means for providing content data that is copyright-protected.

  Copyright protection can be achieved by encrypting the content data into a two-dimensional code and providing a key in exchange for billing registration. However, since it is necessary to execute the decryption processing program in the mobile device (MS), the mobile device (MS) 41 requires a memory area for storing the decryption processing program, and the decryption of the cipher. For this reason, there is a problem in that the power consumption of the mobile device (MS) 41 is increased and the battery duration is reduced.

(Embodiment 1)
FIG. 1 is an overall configuration diagram of a use permission system for two-dimensional coded content data that implements the first embodiment of the present invention.
In the figure, reference numeral 1 denotes content data such as a standby image or an incoming melody, and 2 denotes a two-dimensional code symbol creation device. Reference numeral 3 denotes a print recording medium on which one or a plurality of two-dimensional code symbols 13a, 13b, 13c,... Created by the two-dimensional code symbol creating device 2 are printed and recorded.
The print recording medium 3 may be anything that can print a two-dimensional code symbol, such as paper, plastic film, glass, or metal. Further, it is not necessary to have a single sheet, and it may be a brochure such as a catalog, a newspaper, or a bound book such as a magazine. Printing is not limited to printing using a plate. Data may be directly input and printed, such as a laser printer or an ink jet printer.
Various methods are conventionally known as a two-dimensional coding method, but the QR code (TM) already described in the section of the prior art will be exemplified below.

Reference numeral 4 denotes an apparatus for permitting use of two-dimensionally encoded content data, such as the information providing center (AMP) 44 or the information provider server 48 shown in FIG.
Reference numeral 5 denotes an apparatus for using two-dimensionally encoded content data. For example, the mobile device (MC) 41 with a digital camera shown in FIGS. 4 and 5 is used. 6 is a communication line, for example, from the mobile station (MS) 41 shown in FIG. 4 to the information providing center (AMP) 44 through the base station (BS) 42 and the exchange (MSC) 43, or further This is a communication line to the information provider server 48 on the Internet 47.

In the two-dimensional code symbol creating apparatus 2 described above, content data 1 is input and filed as a content data file 11 according to a predetermined standard specification. In some cases, the content data file 11 has already been created and is simply read.
When the physical representation form of the content is a still image, the content data 1 is obtained by capturing the subject image with a digital camera or a scanner.
When the physical expression form of content is a performance, content data 1 (for example, data conforming to the MIDI (Musical Instrument Digital Interface) standard) is obtained using a performance input device such as a keyboard.
When the physical expression form of the content is a voice or music waveform, the content data 1 can be obtained using a microphone.
In some cases, the content data 1 is once stored in a storage device and then read and input to the two-dimensional code symbol creation device 2.

The content data file 11 shows a standard model of a file structure, and has an essential information element part 11a, a data part 11b, and a remaining part (other part) 11c.
The data portion 11b stores, for example, compressed data that directly corresponds to the information content of the content data 1.
The essential information element portion 11a does not include data directly corresponding to the information content of the content data 1, but stores data necessary for using the content data 1. This essential information element part 11a generally corresponds to a part called “header part”. In the essential information element portion 11a, as will be described later with reference to FIG. 2, a specific standard name of the content data 1, parameters set for the attribute of the content data according to the standard name, and the like Is stored.
Non-essential data is assigned to the remaining portion 11c. For example, there are data indicating the end of the file and a CRC check code for error detection. The CRC check code is created for the content information file 11 including the essential information element part 11a and the data part 11b, but may be created only for the data part 61b.

The two-dimensional code symbol creating apparatus 2 removes the missing data from the content data file 11 by setting a part of the content data file 11 obtained by filing the original content data 1 as a missing data. In addition, a split file creating means for creating a split file by adding use permission access information 12 to the file is provided. In the illustrated example, the case where the above-described missing data is the essential information element portion 11a is described.
The missing data (essential information element portion 11a) is stored in the use permission apparatus 4 for the two-dimensional encoded content data. The two-dimensional encoded content / data usage permission apparatus 4 corresponds to the information providing center 44 or the information provider server 4 shown in FIG.

The missing data (essential information element portion 11a) is stored so that it can be downloaded when the two-dimensionally encoded content / data utilization device 5 accesses the two-dimensionally encoded content / data usage permission device 4. .
The storage location, that is, the location of the missing data (essential information element part 11a) is designated by the two-dimensional code symbol creation device 2 or notified from the two-dimensional coded content data use permission device 4, etc. It shall be known. The use permission access information 12 includes at least data specifying the storage location described above.

The two-dimensional code symbol creating device 2 also has two-dimensional coding means for coding the data of the divided file created by the divided file creating means in accordance with the two-dimensional coding rules. One or a plurality of two-dimensional code symbols 13a, 13b, and 13c encoded by the two-dimensional encoding means are printed on the print recording medium 3 by a printing device (not shown). The two-dimensional code symbols 13a, 13b, and 13c are still data at the stage of being two-dimensionally encoded, and are visualized by being printed.
The two-dimensional code symbol 13a is printed at a predetermined position on the print recording medium 3, for example, at the first position of a series of two-dimensional code symbols.

In the example shown in the figure, the two-dimensional code symbol 13a is printed by converting the use permission access information 12 alone into a two-dimensional code. The data of the divided file including the data portion 11b and the remaining portion 11c is two-dimensionally encoded and printed as two-dimensional code symbols 13b and 13c.
If the data amount of the divided file exceeds the data amount that can be displayed by one two-dimensional code symbol, a plurality of two-dimensional code symbols are used.
In the QR code (TM), one message (in the illustrated example, a combination of the data portion 11b and the remaining portion 11c) can be displayed using a maximum of 16 two-dimensional code symbols. Such a case is called connection (structured append). The header block in each two-dimensional code symbol includes an indicator that indicates the connection mode and a symbol string indicator (indicating the mth in n symbols in the connection structure).

Generally, the data amount of the usage permission access information 12 is small. In such a case, the two-dimensional code symbol 13a is made to coincide with the data capacity of the two-dimensional code symbols 13b and 13c by filling the empty part with pad codewords.
The two-dimensional code symbol 13a has a smaller data capacity than other two-dimensional code symbols 13b and 13c, for example, by reducing the display area thereof, or is displayed with a one-dimensional code, so-called bar code. Can do.
In the above description, the connection mode is set when the data capacity of only the message composed of the data portion 11b and the remaining portion 11c is increased.

Instead of this, the connection mode may be included including the two-dimensional code symbol 13a on which only the usage permission access information 12 is displayed. If the connection mode is set, the processing after the access can be automated in the two-dimensionally encoded content data utilization device 5 described later.
Alternatively, the entire divided file (consisting of the combined use permission access information 12, the data part 11b, and the remaining part 11c) may be two-dimensionally encoded as one message. In this case, the concatenation mode is set when the capacity is insufficient with only one two-dimensional code symbol. In the case described first, the area in which the padding code word is embedded in the two-dimensional code symbol 13a is used effectively.
In addition, the user permission access information 12 may not be printed with a two-dimensional code symbol or a barcode, but may be manually input by the user. In this case, the use permission access information may be printed on the print recording medium 3 in characters.

The print recording medium 3 is provided to the two-dimensional encoded content data utilization device 5.
The two-dimensionally encoded content data utilization device 5 reads reading means (digital camera unit 58 shown in FIG. 5) for reading one or a plurality of two-dimensional code symbols 13a, 13b, 13c printed on the print recording medium 3. And decoding means for decoding one or more read two-dimensional code symbols 13a, 13b, 13c,... To obtain divided file data, and using the two-dimensional encoded content data via the communication line 6. Missing data acquisition means for accessing the permission device 4 and acquiring missing data from the use permission device 4 for the two-dimensional encoded content data, missing data acquired by the missing data acquisition means, and decryption means By restoring the content data file 11 based on the data of the divided file obtained by Having a content data acquisition means for the content data 1 to the available state.
In the mobile device 41 shown in FIG. 5, the functions of the above-described decryption means, missing data acquisition means, and content / data acquisition means are the control programs stored in the memory (ROM / RAM) by the CPU in the control unit 56. Can be executed according to.

By simply reading and decoding the two-dimensional code symbols 13b, 13c,..., The essential information element portion 11a is missing, and only an incomplete data is obtained. 1 cannot be used.
Therefore, the two-dimensional coded content data utilization device 5 uses the two-dimensional coded content data use permission device 12 by using the license permission access information 12 obtained by reading and decoding the two-dimensional code symbol 13a. 4 through the communication line 6 to obtain user permission by performing user authentication and / or billing registration, etc., download the essential information element part 11a that was missing data, and store the data part 11b in the essential information element part 11a. The content data file 11 is completed by combining the remaining portion 11c.
As a result, the copyright-protected content data 1 can be used if the use permission is received, but the content data 1 cannot be used unless the use permission is received.
Since the essential information element part 11a has a smaller data amount than the data part 11b, the communication time is very short even if it is downloaded via the communication line. For this reason, communication costs are hardly incurred.

On the other hand, the use permission apparatus 4 for the two-dimensional encoded content data performs billing registration for the content data 1. When the billing registration is completed, missing data that is not included in the divided files (in the example of FIG. 1, the use permission access information 12, the data part 11b, and the remaining part 11c) of the content data file 11 is completed. (The essential information element part 11a in the example of FIG. 1) is downloaded to the two-dimensionally encoded content data using device 5.
Without charging, the user simply registers as a member in the 2D-encoded content / data usage permission apparatus 4 or authenticates (user authentication) that the user is a member registered in advance or a mobile phone subscriber. You may grant a license when you
When the two-dimensional coded content / data usage permission device 4 is accessed, the advertisement information is received and displayed on the display screen, and the required information element unit 11a is downloaded on condition that the user views the advertisement. By doing so, it may be possible to give a usage permission without charging.
In addition, by transmitting the prepaid card number or the like to the use permission apparatus 4 for the two-dimensionally encoded content data, the user may perform the billing registration without performing user authentication and grant the use permission.
According to the above-described embodiment, since the use permission is performed by accessing the server or the like from the mobile phone terminal or the like, the user authentication and billing registration system for using the copyrighted two-dimensional encoded content data is provided. Can be built.

FIG. 2 is a file configuration diagram for specifically explaining the content data file shown in FIG.
FIG. 2A is the standard model shown in FIG.
FIG. 2B is a PNG file.
A PNG (Portable Network Graphics) file is for transferring monochrome or color still images, and is published by the World Wide Web Consortium (W3C).
The signature chunk described in the first 8 bytes of the file is for identifying the PNG file. Following the signature chunk, multiple chunks are arranged in an almost fixed order. Each chunk includes a data length, a chunk type, chunk data, and a CRC (Cyclic Redundancy Check) code. The chunk includes a critical chunk and an optional ancillary chunk. The signature chunk described above is also a critical chunk.

An IHDR (Image Header chunk) following a signature chunk belongs to a deterministic chunk and is data necessary for image display. For example, image width, height, color depth, color type, compression method, filter method A chunk that contains information specifying an interlace method.
The next IDAT (Image DATa chunk) belongs to a deterministic chunk, and the actual image data (bitmap data) is arranged according to the specified interlace method, subjected to the specified filtering, and compressed using the specified method. It is a chunk that contains the processed data.
The last IEND (Image trailer chunk) is a chunk indicating the end of the PNG file.

In the PNG file described above, the essential information element part 11a corresponds to the signature chunk and the IHDR chunk. This is because without the signature chunk, the type of content is unknown. This is because the original still image data cannot be used without the IHDR chunk.
The data portion 11b corresponds to the IDAT chunk, and the remaining portion 11c corresponds to the IEND chunk. If there are other accompanying chunks, it corresponds to the remaining portion 11c.

FIG. 2C shows a JPEG file.
A JPEG (Joint Photographic Experts Group) file is for irreversibly compressing or saving a photographic image using a JPEG compression technique, and usually refers to JFIF (JPEG File Interchange Format).
A JPEG file consists of data units called segments. Each segment typically has a marker identifier, a marker identifying the segment, a field length, and a field.
The SOI (Start Of Image) segment is a segment of the head marker of compressed data.
The next APPn (Reserved for APPlication segments n) segment is an optional segment and is used to embed information necessary for a JPEG higher-level application in a JPEG file.
The DQT (Define Quantization Table) segment defines the actual state of the quantization table, and defines the quantization factor of the YCbCr spectrum data.

The DHT (Define Huffman table segment) segment defines the actual state of the Huffman coding table.
A DRI (Define Restart Interval) segment is an optional segment that defines the insertion interval of a restart marker (also an optional segment).
The SOF (Start Of Frame) segment is located at the beginning of a frame segment, and indicates various parameters for Huffman coding of DCT (Discrete Cosine Transform) data for that frame.
SOS (Start of Scan) represents various parameters relating to scanning.
The compressed data is image data compressed with a Huffman code.
EOI (End Of Image segment) is a segment indicating the end of the file.
In the JPEG file described above, the essential information element part 11a corresponds to the SOI segment, DQT segment, DHT segment, SOF segment, and SOS segment.
The data portion 11b corresponds to the compressed data, and the remaining portion 11c corresponds to the APPn segment, the DRI segment, and the EOI segment.

FIG. 2D is a SMAF file (Version 3.06).
The SMAF (Synthetic music Mobile Application Format) file is a format specification proposed by Yamaha Corporation that represents synchronized playback multimedia content for mobile terminals.
The data is in the form of a bundle of one or more sequence data (data representation that defines control over the output device over time), and each sequence data is a playback device (sound source device, PCM sound source device, display device). Some of them correspond to the other, and some do not correspond (master track chunk sequence data). All sequences are played back in time synchronization sharing a time axis.

The basic structure is a chunk, and the internal structure of the chunk is composed of a chunk header (Chunk Header) part and a variable-length body (Body) part. A chunk representing the entire SMAF file is called a file chunk, and a chunk sequence is arranged in the body part, and finally a 2-byte CRC check code is added.
The beginning of the chunk sequence is a Contents Info Chunk, followed by an Optional Data Chunk, followed by one or more Track Chunks.

SMAF file management information is assigned to the content info chunk. Stores content class (vendor ID), content type (incoming melody, karaoke, etc.), and content code type (character code system).
Further, it may include a copy status (not possible for each of transfer, storage, and editing), a copy count (number of copies), and options (genre name, song name, artist name, songwriter / composer, etc.).
In the optional data chunk, copyright information such as genre name, song name, artist name, lyrics / composer, picture creator, text copyright holder, content editor, etc. is stored.

A Track Chunk has one or more Score Track Chunks, one or more PCM Audio Track Chunks, one or more Graphics Track Chunks ( Graphics Track Chunk) and Master Track Chunk.
The score track chunk stores sequence data for reproducing the sound source.
The PCM audio track chunk stores PCM audio (ADPCM, MP3, etc.) pronunciation in an event format.
The graphics track chunk stores background images, inserted still images, text data, and sequence data for reproducing them.
The master track chunk stores a music information sequence synchronized with a playback sequence such as a score track, and sequence data for controlling the SMAF playback system.

In the SMAF file described above, the essential information element part 11a corresponds to a chunk header, a content info chunk, and an optional data chunk.
The data portion 11b corresponds to a score track chunk, a PCM audio track chunk, a graphics track chunk, and a master track chunk. A CRC error check code corresponds to the remaining portion 11c.

Returning to FIG. 1 again, the explanation will be supplemented. In the description with reference to FIG. 1, only the essential information element part 11 a is cut out from the content data file 11.
However, a divided file may be created by cutting out a part of the data part 11b and / or a part or all of the remaining part 11c together with the essential information element part 11a to form missing data. Instead of the essential information element part 11a shown in FIG. 1, the cut-out portion is stored in the two-dimensional encoded content data usage permission apparatus 4 and downloaded to the two-dimensional encoded content data utilization apparatus 5. Missing data.

According to this configuration, “part of the data portion 11 b” and / or “part or all of the remaining portion 11 c” are removed from the content data file 11, and in some cases, the use permission access information 12 is changed. In addition, the data of the created divided file is two-dimensionally encoded and printed as two-dimensional code symbols 13b and 13c.
As a result, the two-dimensionally encoded content data utilization device 5 uses the original content data 1 illegally, that is, using the data of the divided file obtained by reading these two-dimensional code symbols. It becomes even more difficult to use the original content data 1 without acquiring missing data.

Further, instead of cutting out all of the essential information element part 11a from the content data file 11, only a part of the essential information element part 11a is cut out, and the cut out part is used for two-dimensional encoded content data. The data may be stored in the permission device 4 and downloaded to the two-dimensionally encoded content data utilization device 5. In this case, the remaining part of the essential information element part 11a is stored in the divided file.
According to this configuration, the data amount of missing data downloaded by the two-dimensionally encoded content data utilization device 5 is further smaller than when all of them are cut out. Therefore, the communication cost required when the utilization apparatus 5 acquires missing data is further suppressed.

Conversely, the essential information element part 11a may be left out of the content data file 11 or only a part thereof may be cut out, and a part of the data part 11b may be cut out. The portion that remains without being cut out is stored in a split file. In this case, the remaining part of the data part 11b may be restored and used. However, even in such a case, the entire content data 1 is not used, and there are cases where it is permissible without a use permission.
For example, using the above-described SMAF file, music (first physical expression form) that sounds the speaker 54 and an image (second physical expression form) displayed on the display unit 57 are reproduced in synchronization. In the case of the content data 1, if only one of the data is stored in the divided file and the license is granted by accessing the license agreement device 4 for the two-dimensional encoded content data, music, images, It is possible to use a license system in which the two are reproduced simultaneously.

FIG. 3 is a flowchart for explaining the operation in the embodiment of the present invention.
FIG. 3A is a flowchart for explaining an example of an operation executed in the two-dimensional code symbol creation device 2. This can be realized by causing a general-purpose personal computer to execute a dedicated application program.
In S21, the content data file 11 is fetched. In S22, the content type is detected based on the file extension.
For example, for a still image, there are a bitmap (BMP) file, a PNG file, a JPEG file, and the like. If the format is not allowed in the two-dimensional coded content data usage permission system, the file format is converted. For example, a bitmap file is converted into a PNG file or JPEG file.
In S23, the essential information element 11a is separated from the file and stored in the memory.
In S24, the information excluding the essential information element 11a and the usage permission access information 12 are stored in the memory as original data (divided file) of the two-dimensional code symbol.

In S25, the number of bytes of the original data described above is calculated.
In S26, various parameters of the two-dimensional code symbol are set. For example, the code type, error correction level, code area, cell size, dot / cell, number of divisions, etc. are set.
When one or more types of one-dimensional codes (bar codes) and one or more types of two-dimensional codes can be used as codes, one is selected from these. Hereinafter, a case where the QR code (TM) is selected will be exemplified.
Error correction coding is performed when converting to QR code (TM). The error correction level represents the correction capability. The code area is a side length of a square area in which a margin is added to the size of one symbol of the QR code (TM). The cell size is the number of dots of the printer head included in the white or black square area of the smallest unit of the QR code (TM) symbol. The division number is a value that specifies how many symbols of the QR code (TM) are used to display the original data.

In S27, a two-dimensional code symbol that satisfies the setting conditions in S25 and S26 is created as bitmap (BMP) or metafile (WMF) data.
In S28, the created data is electronically edited together with other manuscripts and illustrations, and a composition is created by a printer connected to a personal computer.
In S29, plate making is performed using the prepared block and the printing machine prints on paper. The printed paper may be distributed to the user without creating a composition.

FIG. 3B is a flowchart for explaining an example of the operation of the utilization device 5 of the two-dimensional coded content data.
In S31, the two-dimensional code symbol printed and displayed on paper is read and read with a digital camera, and the two-dimensional code symbol is decoded.
In the case of the QR code (TM), regardless of the order of reading a plurality of two-dimensional code symbols, after reading all of them, they are ordered by a symbol string indicator indicating a linked structure. With regard to two-dimensional code symbols in general, a guide for instructing the next reading is displayed on the display unit 57 in FIG. Good.

In S32, a question as to whether or not to proceed to the use permission process for the content provided by the two-dimensional code symbol is displayed on the display unit 57 to prompt the user to make a determination.
When the user operates the key input unit 59 and selects to proceed to the use permission process, the process proceeds to S33. When the process does not proceed to the use permission process, the series of processes is terminated while retaining incomplete data. The unfinished data is stored for the next step of the use permission process so that the process proceeds to S32 without executing the step of S31. Alternatively, unfinished data is erased when a series of processing ends.

In S33, use permission access information indicating the location of the essential information element 11a is acquired based on the read data of the first two-dimensional code symbol 13a.
For example, URI (Uniform Resource Identifiers) or URL (Uniform Resource Locators), which is a notation method for indicating the location of “objects” on the Internet, is acquired, and an HTTP (Hypertext Transfer Protocol) Request with this URI or URL is sent. Then, the essential information element part 11a of each content data 1 located in the content database 47 shown in FIG. 4 is accessed. Alternatively, the essential information element part 11a of each content data 1 located in the database in the information provider server 48 is accessed.

In S34, user authentication and billing registration are performed. In the information providing center 44, user authentication is performed by referring to the registered user database 45 using the terminal identification information of the accessed mobile device (MS) 41 as an argument, and the user is charged and registered.
When the database in the information provider server 48 on the Internet 47 is accessed, the information provider server 48 performs user authentication and billing registration.
Note that the use permission conditions can be set arbitrarily. There are various methods for user authentication and billing registration, and the method is not limited to the above-described example. There may be an accounting server.

In S <b> 35, the two-dimensionally encoded content data utilization apparatus 5 downloads the essential information element 11 a from the information providing center (AMP) 44 or the information provider server 48.
In S36, the content data file 11 is reconstructed by combining the essential information element part 11a, the data part 11b, and the remaining part 11c.
In S37, the content data file 11 is registered in the mobile device (MS) 41 as a menu so that the content data 1 can be used at any time. Alternatively, the content data 1 may be used immediately after downloading, and a still image may be displayed on the display unit 57, or music may be played from the speaker 54. Alternatively, the content data 1 may be transferred to an external device such as a personal computer via the external interface 61.

(Embodiment 2)
In the second embodiment, a similar divided file is created directly from content data without creating a content data file.
In the first embodiment already described, as shown in FIG. 1, first, the content data file 11 is created by converting the content data 1 into a file. After that, by dividing the essential information element portion 11a from the content data file 11 (separated), the use permission access information 12 is added to create a divided file. However, the two-dimensional code symbol creation device 2 only needs to obtain the divided file and the usage permission access information 12. It is not essential to follow the procedure of creating the content data file 11.
FIG. 6 is a schematic diagram showing a procedure for creating a split file according to Embodiment 2 of the present invention. In FIG. 6, the same parts as those shown in FIG. 2 are denoted by the same reference numerals as those in FIG.

The format of the content data file 11 is determined in advance by a standard or an original standard. That is, in the example of FIG. 2A, there are the essential information element part 11a, the data part 11b, and the remaining part 11c, and what data is stored in each is predetermined.
Therefore, the data (essential information element part 11a) (referred to as missing data) corresponding to a part of the data (content data file 11) when the original content data is converted into a file is converted into the content data file 11 Are created as data independent of the content data file 11 without actually creating them.
Similarly, based on data (data portion 11b and remaining portion 11c) corresponding to data obtained by excluding the above-described missing data from data (content data file 11) when the original content data is filed. The divided file 71 is created without actually creating the data (content data file 11) when the original content data is filed.

Specifically, referring to FIG. 2, data directly corresponding to the information content of the content data 1, for example, the original content data itself or data after processing such as data compression is performed. Is the data portion 11b (IDAT in FIG. 2B, compressed data in FIG. 2C, etc.).
As in the first embodiment, non-essential data, for example, data indicating the end of the file, CRC check code for error detection, and the like are stored in the remaining portion 11c. Note that the CRC check code can be processed more easily if it is created only for the data portion 11b.
Thereafter, the divided file 71 is created by adding the usage permission access information 12 to the data portion 11b and the remaining portion 11c as the case may be.
On the other hand, in the essential information element section 11a, data necessary for using the content data 1 is stored as in the first embodiment. That is, the data corresponding to the data in the data part 11b (data shown in the hatched part in FIG. 2) is stored in the essential information element part 11a.
The created divided file 71 is encoded and printed in the same manner as described in the first embodiment. The essential information element unit 11a is stored in the use permission apparatus 4 for the two-dimensional encoded content data in the same manner as described in the first embodiment.

  On the other hand, the two-dimensionally encoded content / data utilization device 5 decodes one or more two-dimensional code symbols that have been read in the same manner as described in the first embodiment, and “data portion 11b, residual portion 11c and utilization” The permission access information 12 "(divided file 71) is acquired, and the essential information element part 11a is downloaded. Thereafter, the utilization device 5 combines the data portion 11b and the remaining portion 11c of the divided file 71 with the essential information element portion 11a, thereby making the original content data filed (used by the utilization device 5). A file in a possible format, that is, the content data file 11 described in the first embodiment (see FIG. 1) can be obtained, that is, completed.

Similar to the first embodiment, the following modifications are possible.
Together with the essential information element part 11a, the data “part of the data part 11b” and / or “part or all of the remaining part 11c” are stored as missing data in the use permission apparatus 4 for the two-dimensional encoded content data. The data may be downloaded to the two-dimensionally encoded content data utilization device 5. The remaining portion that does not become missing data is stored in a split file.
Alternatively, only a part of the essential information element portion 11a may be stored as missing data in the two-dimensional encoded content data usage permission apparatus 4 and downloaded as data to the two-dimensional encoded content data utilization apparatus 5. Good. The remaining portion that does not become missing data is stored in a split file.
On the other hand, the essential information element part 11a of the content data file 11 is not used or only a part thereof is used, and a part of the data part 11b is used to generate two-dimensional encoded content data as missing data. May be stored in the use permission apparatus 4. The remaining portion that does not become missing data is stored in a split file.

In the above description, the case where the mobile device (MS) 41 with a digital camera is used as an example of the two-dimensional encoded content data utilization device 5 is described. However, instead of using a digital camera, a mobile device ( MS) 41 may be used to read the two-dimensional code symbols 13a, 13b, 13c,..., Or the two-dimensional code symbols read on the personal computer connected to the external interface 61 The read data of 13a, 13b, 13c,... May be transferred to the mobile device (MS) 41.
Further, instead of the mobile device 41, a terminal device such as a PDA (Personal Digital Assistant) connected to a mobile phone network may be used. It may be a personal computer that is accessed via a wired communication network to a server as the use permission apparatus 5 for two-dimensional encoded content data.

In the above description, a case where a general-purpose personal computer is used is illustrated as an embodiment of the two-dimensional code symbol creating apparatus 2 of the present invention. However, a device dedicated to creating a two-dimensional code symbol may be used, and the mobile device 41, the terminal device, or the like may have a function of creating a two-dimensional code symbol.
A case where the mobile device 41 shown in FIG. 5 is provided will be described. A two-dimensional image according to the present invention is applied to a PNG file of an image taken by the digital camera unit 58 of the mobile device 41, or other content data file downloaded from a mobile phone network or input from an external interface 61 or the like. Perform the code symbol creation function. The created two-dimensional code symbol (data) can be supplied to a printing machine via a mobile phone network or via the external interface 61 and printed on a print recording medium.
In this case, the mobile device 41 can also create a conventional two-dimensional code symbol (data) having no missing data. Further, the two-dimensional code symbol can be visually displayed on its own display unit 57.

In the above description, the system has been described in which the use permission apparatus 5 for the two-dimensional encoded content data accessed via the wireless line 6 is used to download missing data such as the essential information element unit 11a.
Instead, a print recording medium such as a label sheet on which a two-dimensional code symbol obtained by converting the missing data into a two-dimensional code is obtained by obtaining a use permission. A system is also conceivable in which the content data file 11 is reconstructed on the basis of the missing data and the data of the divided files by reading with a camera and decrypted so that the content data 1 can be used.
