Hereinafter, various embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of a multimedia information service apparatus according to the present invention. The multimedia information service device according to FIG. 1 includes a management server 12, a service server 13 that services multimedia information,
A medium 1 having a user terminal 16 connected to each server 12 and 13 through a communication network 11, an image device 15 for inputting an image to the user terminal 16 and a code image distributed by the management server 13 or the service server 13.
Including 4.

The management server 12 is a service server 13
When the request for index code allocation is made, the service server 13 is allocated an index code, and an address database DB, 12b for storing the index code and information corresponding to the index code, for example, the network address of the service server 13, is provided. Here, the network address is indicated by letters, numbers, and special characters to indicate the position of the specific equipment in the network environment, and URL (Univ
ersal Resource Locator), IP (Internet Protocol)
It may be an address, a telephone number, or a unique identification number of the wire / wireless communication terminal.

The management server 12 also indicates the user access control information including at least one of the number of times of use, the period of use, and the amount of use by a recognition code, and stores the recognition code and the user access control information corresponding to the recognition code. The recognition code DB 12a is provided. Here, the recognition code can be said to be data that the user has decided for certain multimedia information with respect to the authority to use the multimedia information, and can be said to define rights contents such as a kind of copyright. . On the other hand, although there are cases where identification codes are given to individual multimedia information, it is necessary to give a certain range of rights to individual users or all users on a server-by-multimedia basis. Or the content of rights to multimedia information of a specific group.

The service server 13 includes an information DB (not shown) for storing multimedia information, and an identification code DB (not shown) for storing the identification code and user access control information corresponding to the identification code. Can be equipped. In addition to the above-mentioned information, the user access control information may include information that distinguishes the user, for example, a user ID, and may identify whether the user is a legitimate user. here,
Although the management server 12 and the service server 13 are separately shown in FIG. 1, the management server 12 serves as an intermediary between multimedia services, and the service server 13 actually provides multimedia information to users. Of course, these functions can be operated by one server, and can also be operated by a form in which a plurality of service servers 13 join the management server 12.

The user terminal 16 is a computer, a mobile phone, a PDA (Personal Digital Assistant), a smart phone, an IMT (International Mobile Telecommunication) -2.
000 terminals.

The management server 12 has an algorithm for converting a code including at least an identification code into a code image, and also provides the algorithm to the service server 13.

The code image is generated by converting one or more characters or numbers included in the code information according to a predetermined code system that maps each character and number in a predetermined color as shown in FIG. Predetermined shape,
An image made up of colors, patterns or combinations of these (which may include letters and numbers). Typical examples of this are barcodes and codes such as PDF-417,
1D or 2D black and white or color cells (or lines)
This is also the case for the more detailed metrics image.

The encoding method according to the code system of FIG. 2 is a method of converting various characters and numbers into codes and then generating a code image with a color assigned to each code. In this example, a code image is generated using eight colors, and two consecutive cells are used to represent one character or number. For each color
Codes from 000 "to" 111 "are assigned. For example, the number 3 is assigned to the code" 000 011 ",
It is encoded with the color assigned to the code "000" and the color assigned to the code "011", and imaged with the cell made of the two colors.

Although FIG. 2 shows the colors in black and white gray levels due to the limitation of drawing, it is possible to use black and white gray levels in actual application, but it is realized by a combination of color hues. This is more advantageous for code recognition, and the number of hues depends on the performance of a device that prints color (eg, printer) or a device that recognizes color (eg, scanner). Such a code image exists in a visual form or in the form of file data that can be read by a computer, and the code image contains code information represented by letters and numbers.

After encoding various characters and numbers included in personal information by the method shown in FIG. 2, the color corresponding to the code can be expressed in a square matrix form composed of a combination of square cells. May be expressed in the form of a linear barcode. Also, it is needless to say that it is possible to code in consideration of the distance between cells (lines) while creating a code table, and to make a form in which square cells and linear lines can be combined with each other. . Providing an encoding algorithm that can be coded with various physical expressions in this way allows flexibility in the expression of a wider variety of characters (eg, Kanji, Japanese, etc. as well as Hangul and the alphabet).

An example of a color matrix image in the code image includes a data area in which actual code information is encoded and a reference area formed by a reference cell used as a reference color in a decoding process. Can be done. Here, the reference area is used to set a reference color for recognizing the color represented in the data area. The hue may be printed differently depending on the model of printing and the material of the printing paper, and the same hue may be recognized as slightly different depending on the characteristics of the scanner or the camera. With this in mind, the reference cells in the reference area provide a reference for determining the hue displayed in the data area. That is, the hue displayed in the cell of the data area has a relative color difference compared with the standard color of the reference area. Therefore, even if the image input device or the output device is changed, the hue difference between the reference area and the data area is constant, so that the hue of the cell expressed in the data area can be accurately recognized. As a result, decoding can be performed with more reliable code information. In addition, the color matrix image may further include parity cells as well as data cells. Here, the parity is for checking whether or not there is an error in the original code data represented by an image, and is included in the row (column) at the end of one row and / or the end of one column, for example. It can be displayed as a cell having a specific hue depending on whether the number of bits whose digital data bit value is "1" is odd or even.

The number of cells included in the color matrix image can be appropriately determined in consideration of the number of characters of the personal information, and its structure is preferably N (M size matrix type, but the user's needs and the code image are In consideration of the characteristics of the medium to be expressed, it can be expressed in any shape such as a circle or an ellipse, and may be displayed in multiple positions.The color matrix code image includes only the color combinations of the cells included in the image. However, it is possible to further include a line pattern inside each color cell or to express the form of each cell differently.

The service server 13 provides multimedia information such as music, voice, moving images, animations, graphics, letters or numbers. The service server 13 can distribute online the code image in which the recognition code and the network address information are encoded by the algorithm provided by the management server 12. Here, the network address information is a network address or an index indicating the network address.

The code image is also shown in FIGS.
It may be distributed in a printed form or an attached form on a card-shaped medium as shown in D. The code image may be distributed with the recognition code encoded by the management server 12.

The user terminal 16 receives the code image or the code image in the form of a file obtained from the predetermined medium 14 through the image device 15 such as a scanner, and stores the code image in the memory, disk, buffer or screen of the computer. The image device 15 is a device that can obtain visual information using light, and corresponds to a PC camera, a digital camera, or a scanner. Even if the input is not made by the image device 15, an image suitable for the code system can be created by programming or graphic software.

The user terminal 16 transmits the input code image to the management server 12, obtains the decoded result from the management server 12, or directly decodes it by driving a decoding algorithm. The decoded result connects to the management server 12 or the service server 13 to authenticate whether the recognition code is valid, and the user is served multimedia information from the service server 13.

According to an embodiment of the present invention, a multimedia information provider distributes a code image in which code information is encoded by a predetermined encoding algorithm to a user, and the user encodes a code image by a corresponding decoding algorithm. Decode the image to get the original code information.

The management server 12 encodes data using color or color and pattern to generate a code image, and decodes the code image to restore the original data. To have. The user terminal 16 may be used to download the decoding program from the management server 12 and directly decode the code image. The service server 13 downloads the encoding program from the management server 12 and encodes it with a code image including a recognition code and network address information. The network address information is a network address of the service server 13 or an index indicating the network address. If the user terminal 16 or the service server 13 does not download the decoding or encoding program, the user terminal 16 or the service server 13 may be connected to the management server 12 to perform decoding or encoding.

Here, the encoding method is divided into a direct encoding method and an index encoding method. The direct encoding method is a method in which all recognition codes and network addresses are converted into code image forms depending on the code system. The index encoding method is a method of converting an index related to an address database or file containing network addresses into an image form according to a code system. The encoded image can be automatically output by a program algorithm, or may be produced manually by a graphic editor or a code conversion system.

Decoding is to find information defined in a code system from a code image and convert it into code information according to the code system. The code information is made up of characters, numbers, special characters or combinations thereof that can be displayed by a computer, but has different meanings depending on the encoding method.

The decoding method is roughly classified into a direct decoding method and an index decoding method according to the information contained in the code. In the direct decoding method, when the code image is decoded, the network address is immediately extracted when the recognition code and the network address are included in the code system. In index decoding schemes, the result is an index into a database or file containing network address information.

In the decoding process, a process of finding a meaningful form, color, pattern or character included in the code image is required, and in addition, a process of correcting a distorted image is required. Where RGB (Red, Green, Bl
ue) model, HSV (Hue angle, Saturation, Value) model, CMY (Cyan, Magenta, Yellow) model, HLS (Hue ang)
It is possible to distinguish colors using one or more methods in the le, Lightness, Saturation model. Boundary line detection and thinning algorithms can also be used to detect features and patterns.

4A to 4D show examples of the structure of the code and its contents at the time of encoding or decoding. FIG. 4A shows an example in which only the recognition code 41 is used. The identification code is a product number for recognizing the generated code, and the user connects to the user access control information such as the number of times of use, the amount of money used, the period of use, user terminal information, or the management server 12. It is a number that manages information such as history. For example, if a user purchases a code with a limited number of times of use, the usability can be determined by reducing the number of times of counting the number of times of use each time the code is used. In addition, by storing information such as a terminal device in which the code is used, a history, and a user ID, it is possible to confirm whether the use is restricted or an authorized user when necessary.

FIG. 5 shows an example of a database structure for a code composed only of recognition codes. The database according to FIG. 5 has an identification code field 5
1. Counter field 52 and user for down-counting the number of connections corresponding to identification code field 51
A user field 53 for confirming the ID is provided.

FIG. 4B shows an example in which address information 42 of the service server 13 is further provided in addition to the recognition code 41. The address information 42 can be a network address or an index. The network address means a certain address that indicates a specific equipment as an Internet IP address, URL, domain name, and other network character and number information. The index is a database for managing the addresses of the network, and is a kind of referrer for searching the information. FIG. 6 shows an example of the structure of the database related to the index method code. The database according to FIG. 6 includes an index field 61 and an actual address information field 62 corresponding to the index field 61. The index field 61 stores information about the actual address information field 62 of the service server 13 in the management server 12
The key value used when trying to find it in the address database 12b. That is, for example, if "comsciyonseiackr" is input as the index information, the management server 12 detects and outputs "comsci.yonsei.ac.kr" of the actual address information linked to the index information. If "comsci.yonsei.ac.kr" in the actual address information is changed to another address, the address information changed in the previous index information can be changed to the user by correcting the content of the actual address information field 62. Will be able to provide. On the other hand, the content referred to by the index information can function as further index information, and in this case, the actual address information can be detected by tracking the information by further index information.

The management server stored in the actual address information field 62 can be expressed in various ways, and in particular, the URL and the IP address indicating the address of the Internet site are representative.

FIG. 4C shows an identification code 41 and address information 4.
2 shows an example in which service information 43 is added to 2. The service information 43 is for using a specific network service such as a web service, a telnet service, an email service, and a gopher.
Services, services defined by URL such as FTP (File Transfer Protocol) are included.

FIG. 4D shows a case where the address information is subdivided into host information 44 and additional information 45 in the structure of FIG. 4C. Here, the additional information 45 may be a directory or a parameter.

FIG. 7 is a flowchart showing the code image generating method according to the present invention. The code image generation method shown in FIG. 7 will be described with reference to the system configuration diagram of FIG.

The service server 13 is the management server 12
Apply for index code allocation (Step 71). That is, the service server 13 transmits its network address to the management server 12, and applies the index code based on the network address to the management server 12. Management server 12
Assigns an index code corresponding to the network address and stores the index code and the corresponding network address in the address DB 12b (step 72).

The management server 12 transmits the encoding algorithm to the service server 13. If the service server 13 has already downloaded and provided the encoding program provided by the management server 12, the management server 12 transmits the index code to the service server 13 (step 73).
The management server 12 generates user access control information,
This is shown by a recognition code, and the recognition code and the user access control information corresponding to it are shown in the recognition code database 12
Store in a (74 steps).

The management server 13 uses an encoding program to convert the recognition code into a code image that is physically or electronically represented. The service server 13 also converts the code including the recognition code and the network address information into a code image using the encoding program (step 75).

The code image generated in the above steps is distributed to the user in a predetermined format. As the distribution format, the code image is distributed in a state in which it is printed or attached to a medium such as a card, and in a state in which it can be read by a computer (for example, an image which can be directly displayed on a monitor screen or read by an image editing program). File format) can also be distributed.

FIG. 8 is a flow chart of a method for a user to serve multimedia information using a code image he / she bought. A method of servicing the multimedia information shown in FIG. 8 will be described with reference to the system configuration diagram of FIG.

It is done by clicking a button on a digital camera or by inserting a code into the reader slot.
If the code image is input, the user terminal 16 decodes the code image using a decoding program (step 81). At this time, the user terminal 16
If there is no decoding program in
The user terminal 16 sends the code image to the management server 12
Then, the user terminal 16 can obtain the decoded code information from the management server 12.

From the decoded code information, it is determined whether the code information has only the recognition code or the address information in addition to the recognition code (step 82). As a result of the determination, if the code has only the recognition code, the network address is manually set or designated as the basic value (step 91), and the user terminal 16 drives the service program set to the basic value (86). Stages). If the code also has address information as a result of the determination, it is determined whether the address information is an index (step 83). As a result of the determination, if the address information is a network address that is not an index, the corresponding network address is automatically set (step 92), and the user terminal 16 drives the service program set to the basic value (step 86). As a result of the determination, if the address information is the index, the index is searched (step 84). At this time, in the index search, the user terminal 16 transmits the index code to the management server 12, and the management server 1
2 retrieves the address database 12a and transmits the retrieved network address information to the user terminal 16. The user terminal 16 sets the network address information linked to the index (step 85).

If the network address information is set, the user terminal 16 drives the service program (86
Then, the service server 13 is connected (step 87).
At this time, the service program is driven by the service information set in the code, but if the code does not have the service information, the service set to the basic value is provided inside the program. For example, if the address information is a URL, U
The service is determined by the protocol defined in RL,
If the address information is simply a network address and the basic service is defined in Telnet, it will drive the Telnet client program.

The service server 13 or the management server 12 checks the identification code in the decoded code and also checks the user access control information such as the valid period or the number of connections to check whether it is valid or not. (88 steps). In addition, it may be confirmed whether the connected user is an authorized user by checking the user ID in the data stored in the identification code database. When the identification code or the user authentication is completed, the user selects the required service among the services provided by the service server 13 (step 89), and the service server 13 provides the user with the service selected by the user. Provide (90 steps).
