Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a content obtaining method, a content providing method, a content obtaining apparatus, a content providing apparatus, a content obtaining program, and a content providing program, and more particularly to a communication network such as the Internet and a magazine / television. Content acquisition method, content provision method, content acquisition apparatus, content acquisition apparatus, content acquisition program, content acquisition program, and content provision for acquiring or providing content and related information and services to content users via an information transmission medium About the program.

[0002]

2. Description of the Related Art Today, services such as music and video are provided to users on the Internet and the like. These include, for example, music content data together with information related thereto, and WWW (world wide).
Web) pages are often used, and the user often downloads and uses them as needed.

[0003] In addition, information transmission media such as magazines,
A form of providing a user with content such as an analog photograph has existed for some time.

[0004] In any of the above two information providing modes, it is difficult for a user to obtain a content data for a certain purpose and then use a service having another function related to the content data. . For example, a user who wants to "listen to" the music of the first musician, searches for a service provider that provides the content data of the music by some means such as a search engine, downloads the content data from there, and views the music. But if you want another service like "I want to watch a video clip of this song",
The trouble of searching for the service provider that provides the video clip video content data again by some means arises.

[0005] Alternatively, it is difficult to provide a service using a different information transmission medium, for example, when it is desired to listen to a musician's music as digital content from an analog photograph of the musician viewed in a magazine or the like.

[0006] In order to solve these problems, unique identification information (content ID) is assigned to the content, the content ID is distributed together with the content data, and the user wants to obtain information related to the content data. , A method of sending information corresponding to a content ID to a server when the server sends the content ID to the server has been proposed in Japanese Patent Application No. 2000-066755 "Content distribution method".

However, in the above-mentioned method according to the conventional 2000-067550, it is not possible to tell the server in what environment the user wants the service, so that all user environments can be used. Only uniform services can be provided.

For example, suppose that a photograph of Tokyo Tower is published in a magazine, and there are two users who want to digitally obtain a map image near Tokyo Tower from the photograph. One terminal is a PC capable of displaying a very high-definition image, and the other terminal is a portable terminal having only a display device with a low resolution. At this time, the content ID
If the server that provides the map information provides a high-resolution map image adapted to the PC, the portable terminal is too large to display well and is very difficult to use. vice versa,
When adapted to a mobile terminal, there is a problem that a PC is too small to be easily recognized. Or, even if the functions of the terminals are the same, one request is "I want to see a color map image even if the traffic is large," and the other is "I want to obtain it with less traffic because it may be black and white. It is also difficult to reflect the user's detailed conditions such as the request.

As described above, the conventional content providing system has four major problems.

First, when providing services related to contents, the environment of the user is not taken into consideration. When a user requests the provision of a service function related to contents data, the service is not considered. It provides a uniform service without considering the capabilities of the user terminal and the conditions of the user (the image may be black and white, so the download is fast, etc.).

[0010] Second, there is no unified method for receiving various different services from content data. For a certain content data, there are individual related information services related thereto. However, there is no way to provide different services in accordance with a user's function request in a unified manner.

Third, in particular, seamless services cannot be provided between different information transmission media such as analog and digital.
If it is closed only to the WW, related services can be provided using a structure such as a hyperlink.
It is difficult to combine magazine data and content data on different information media such as music content data on the WWW in a unified and user-friendly manner.

Fourthly, it is not possible to conduct a uniform and seamless content distribution survey and usage survey between a plurality of information transmission media such as analog and digital media.
Distribution surveys and usage surveys of content data distributed on digital media can be easily performed using a search engine, but digital data is converted to analog media such as magazines and distributed. It is not possible to carry out distribution and usage surveys on both analog and digital at the same time, such as being converted to photographs and digital data and posted on homepages.

[0013] The present invention has been made in view of the above points. When content data is distributed through a digital communication network such as an Internet or an information transmission medium such as a magazine or a television, a user can use the content data based on the content data. It is possible to provide a method for distributing / receiving content data / information according to the user's environment and conditions without being conscious of the difference in the information transmission medium when receiving a service having another function. It is an object of the present invention to provide a possible content acquisition method, a content providing method, a content acquiring device, a content providing device, a content acquiring program, and a content providing program.

[0014] A further object of the present invention is to provide a content provider with the same effect regardless of the information transmission medium.

[Third Embodiment] An example has been shown in which the content ID reading unit 120 in the first embodiment and the content ID reading device 120 in the second embodiment are mounted in the client terminal 100. In this embodiment, a description will be given of a design method for keeping the content ID reading unit in a safe design when it is desired to protect the internal function of the content ID reading device from analysis such as reverse engineering, such as content distribution survey and usage survey. I do.

FIG. 11 is a diagram for explaining the distributed processing of the content ID reading unit according to the third embodiment of the present invention.

As shown in the figure, the content ID reading section 120 of the first embodiment is improved, and the portion where the security of the content ID reading section is desired to be ensured is outside the client terminal (server 600). The other parts are processed in the client terminal 100.

Here, specifically, as described in the first and second embodiments, the content ID reading unit 120 writes the content in the header area of the content in an encrypted or special format. And the like, for example, a process of decoding a content ID, a process of reading a digital watermark, and the like.

First, as shown in FIG.
The D reading process is divided into a processing part group A that can be disclosed to the public and has no security problem, and a processing part group B that needs to be kept secret from the public in order to maintain security.

The processing parts belonging to the processing part group A are divided into a user-side content ID reading processing unit 1201, a user-side content ID reading processing unit 1202,... Each processing mechanism is implemented in the client terminal. The processing part belonging to the processing part group B is a server-side content ID reading processing unit 61.
01, server-side content ID read processing unit 6102
,..., Server-side content ID read processing unit 610n
Each processing mechanism is implemented in the server 600 outside the client terminal.

The content ID reading process in the above configuration will be described.

FIG. 13 is a sequence chart for explaining a content ID reading process according to the third embodiment of the present invention.

Step 301) The contents data input by the contents user is transmitted to the client terminal 100.
Is input to the user-side content ID read processing unit (1).

Step 302) The counter is set to k = 1.

Step 303) The content ID reading processing section (k = 1) on the user side reads the content ID using the processing part group A.

Step 304) When the counter k is k <n
If so, the process proceeds to step 305; otherwise, the process proceeds to step 310.

Step 305) The result processed by the content ID reading processing section (k) on the user side is
Send to 00.

Step 306) In the server-side content ID reading processing section (k) of the server 600, processing for reading the content ID is performed by the processing part group B.

Step 307) The counter k is incremented.

Step 308) The result of reading in the server 600 is transmitted to the content ID reading processing section (k + 1) on the user side of the client terminal.

Step 309) The content ID reading processing section (k + 1) on the user side of the client terminal receives the result of reading by the server 600, and proceeds to step 303.

Step 310) If k ≧ n, the result of reading by the content ID reading unit of the client terminal is output.

Here, the server 600 may be a content providing device, or may be another server dedicated to content ID reading processing.

Considering the case where the content ID reading unit is a digital watermark reading process, the current digital watermark embedding process and the current process of reading the digital watermark are symmetrical. You will find the other way. Only the same method as "common key cryptography" in cryptography is realized. That is, by analyzing the digital watermark reading method by the content user, the content I embedded in the content is obtained.
D can be deleted or altered. As a result, when the digital watermark technique is used, all systems can be broken. Also, in order to solve this problem, a method of implementing a digital watermark reading function in a tamper-resistant device that can be connected to a client terminal, or sending a content to be read with a digital watermark to a remote server having a digital watermark reading function, A method of preventing the user from analyzing the digital watermarking method, such as a method of transmitting only the result, is also conceivable.

However, the production cost of a tamper-resistant device is high, and it is difficult for a user to obtain it at low cost.
Also, it is difficult to execute as a program, and the feasibility is low. When using a remote server,
First, it is necessary to perform a process of transmitting the content from the content user to the server, and since the content data is often very large, this communication time causes a decrease in performance. Furthermore, since the amount of processing for reading digital watermarks is generally large to some extent, when reading processing is performed in response to requests from many content users at the same time, the load on the server becomes extremely large.

In this embodiment, such a problem can be dealt with.

It should be noted that each component of the client terminal of FIG. 6, the content providing device, the client terminal of FIG. 8, and the content location information management device of FIG. 10 in the first embodiment can be constructed as a program. Yes, these programs can be stored in disk devices connected to each device, floppy (registered trademark) disks,
It is also possible to store the program in a portable storage medium such as a CD-ROM, and to install and execute the present invention when implementing the present invention. Further, these programs can be installed in each device via a communication network.

Further, in the client terminal, it is also possible to temporarily store the content input from the content user in a storage medium such as a disk device of the client terminal.

The present invention is not limited to the above-described embodiment, but can be variously modified and applied within the scope of the claims.

[0173]

As described above, according to the present invention, when content data is distributed through a digital communication network such as the Internet or an information transmission medium such as a magazine or a television, the content data can be further used by the user. In addition, when a service having another function is desired, the content data and information can be distributed according to the environment and conditions of the user without being aware of the difference in the information transmission medium.

Further, when reading the content ID from the content input by the content user, the content ID can be safely read.
