Description

  The present invention relates to, for example, a package file distribution system in a system for distributing image data over a network, a package file distribution method for a package file distribution system, a package file distribution server device, a package file distribution server program, a package file reproduction terminal device, and a package file The present invention relates to a reproduction terminal program and a file package terminal device.

In the transmission of audio and moving images, a container format that can hold various types of data and data compressed by a standard data compression method is often used.
WAV, AIFF, AVI, MOV, and MPEG are examples of container formats.

  Also, in order to collect access information, it is necessary to embed javascript (registered trademark) in the HTML of the WEB page.

Audio, video, subtitles, chapters (chapters), subtitles, metadata (tags), etc. can be compressed and stored in a container format to identify and organize various types of data.
However, the inventory, which is character information, is not held as one piece with a moving picture stored in the container format.

The inventory is managed in a database separate from videos, etc., and if the database is broken, it will not be possible to deal with videos. That is, the data maintenance efficiency is low.
In this case, it is necessary to extract an inventory of personal information and specific keywords from a moving image or the like using a special application.

There is authentication for specific container formats such as WMRM (Windows Media Rights Management) (Windows is a registered trademark), but its versatility is low.
There is no container format for still images.

In S220, the package file access unit 330 of the package file delivery server apparatus 300 receives the package file delivery request from the package file playback terminal apparatus 400.
The package file distribution request is data specifying a package file 110 (hereinafter referred to as “distribution request file”) that the user wants to download.

For example, the package file distribution request unit 420 of the package file playback terminal device 400 displays a distribution request screen. The distribution request screen is a screen listing the package IDs of the package file 110 distributed from the package file distribution server device 300. The user selects the package file 110 to be downloaded from the list on the distribution request screen.
The package file distribution request unit 420 transmits a package file distribution request specifying the selected package file 110 as a distribution request file, and the access processing unit 320 receives the package file distribution request.

  It progresses to S230 after S220.

In S230, the login inquiry unit 331 acquires the distribution request file specified in the package file distribution request from the package file storage unit 390.
The login inquiring unit 331 determines whether or not to permit distribution based on the permission authentication data included in the DRM information 112 of the distribution request file.

For example, the login inquiry unit 331 permits distribution when the permission authentication data indicates “no browsing permission”.
In addition, when the permission authentication data indicates “browsing permission exists”, the login inquiry unit 331 issues a user authentication request including the user ID of the distribution login data and the “permission confirmation method” included in the permission authentication data. Send to. The user authentication device is designated as “permission confirmation destination” in the permission authentication data.
The user authentication device stores attribute information such as age and type (free user, paid user) in association with a user ID for each registered user.
The user authentication device determines whether to permit distribution based on the attribute information of the registered user corresponding to the user ID included in the user authentication request and the “permission confirmation method”. For example, if the age of the registered user is 20 and the “permission confirmation method” is “18 years old or older” and the age is restricted, distribution is permitted. If the type of registered user is “free user” and the “permission confirmation method” restricts free users, distribution is rejected.
The user authentication device returns a determination result, and the login inquiry unit 331 uses the determination result of the user authentication device.

After the authentication is permitted in S230, the process proceeds to S240.
If authentication is not permitted in S230, the package file delivery unit 332 returns a delivery error screen, and the package file delivery request unit 420 of the package file playback terminal device 400 displays the delivery error screen. In this case, the user returns to the distribution request screen and specifies the package file 110 again.

In S240, the package file distribution unit 332 adds the user ID of the distribution login data to the DRM information 112 of the distribution request file. Hereinafter, the user ID added to the DRM information 112 is referred to as “distribution login ID”.
The package file distribution unit 332 transmits the distribution request file to which the distribution login ID is added to the package file reproduction terminal device 400.
The package file receiving unit 421 of the package file playback terminal device 400 receives the distribution request file, and stores the received distribution request file (package file 110) in the terminal storage unit 490.
By S240, the package file distribution process ends.

FIG. 8 is a flowchart showing package file playback processing in the first embodiment.
The package file reproduction process in the first embodiment will be described below with reference to FIG.

  In S310, the package file reproduction unit 430 of the package file reproduction terminal device 400 inputs the package ID of the package file 110 that the user wants to reproduce and the user ID for the image distribution service.

For example, the user activates the package file reproduction unit 430 to reproduce the package file 110.
The package file playback unit 430 displays a login screen for inputting a user ID, and the user inputs the user ID for the image distribution service on the login screen.
The package file playback unit 430 displays a list of the package files 110 stored in the terminal storage unit 490, and the user selects the package file 110 (package ID) from the list.

  The user may first specify the package file 110, and when the package file 110 is specified, the package file playback unit 430 may be activated, and then the package file playback unit 430 may request a user ID on the login screen.

Hereinafter, the user ID input in S310 is referred to as “reproduction login ID”.
Further, the package file 110 designated in S310 is referred to as a “reproduction request file”.

  It progresses to S320 after S310.

  In S320, the DRM information confirmation unit 431 acquires the reproduction request file from the terminal storage unit 490, and determines whether or not reproduction of the reproduction request file is permitted as follows.

The DRM information confirmation unit 431 compares the reproduction login ID with the distribution login ID included in the DRM information 112 of the reproduction request file.
If the reproduction login ID and the distribution login ID match, the DRM information confirmation unit 431 permits the reproduction of the reproduction request file.
When the reproduction login ID and the distribution login ID do not match, the DRM information confirmation unit 431 refers to the copy permission data included in the DRM information 112 of the reproduction request file.
When the copy permission data indicates “copy permission”, the DRM information confirmation unit 431 permits the playback of the playback request file.
When the copy permission data does not indicate “copy permission”, the DRM information confirmation unit 431 does not permit the playback of the playback request file. When “duplication permission” is not indicated, when the copy permission data indicates “copy not permitted”, when the DRM information 112 does not include the copy permission data, the copy permission data indicates “duplication permitted” and “duplication not permitted”. This is the case where a value other than “” is specified. This is because there are cases where the DRM information 112 is falsified and the DRM information 112 does not include copy permission data, or the copy permission data indicates an unspecified value.

  It progresses to S321 after S320.

If reproduction is permitted in S321 (YES), the process proceeds to S330.
When reproduction is not permitted in S321 (NO), the package file reproduction unit 430 displays a reproduction error screen, and the package file reproduction process ends. At this time, the reproduction request file may be destroyed so that the image data 113 cannot be reproduced.

In S330, the package file playback unit 430 displays the image data 113 included in the playback request file on the display device.
By S330, the package file reproduction process ends.

By the above-described image delivery method, for example, the reproduction of the package file 110 can be restricted as follows.
If “18 years or older” is set as the permission authentication method in the DRM information 112 of the package file 110 and “duplication not permitted” is set as the copy permission data, the image data 113 distributed to users 18 years or older is less than 18 years old. Can be prevented from being played by other users.
If “copy permission” is set as copy permission data in the DRM information 112 of the package file 110, a plurality of users using the package file playback terminal device 400 can play the image data 113.

FIG. 9 is a diagram illustrating an example of hardware resources of the image distribution system 100 according to the first embodiment.
In FIG. 9, a file package terminal device 200, a package file distribution server device 300, and a package file playback terminal device 400 include a CPU 911 (Central Processing Unit) (also referred to as a microprocessor or a microcomputer). The CPU 911 is connected to the ROM 913, the RAM 914, the communication board 915, the display device 901, the keyboard 902, the mouse 903, the drive device 904, and the magnetic disk device 920 via the bus 912, and controls these hardware devices. The drive device 904 is a device that reads and writes a storage medium such as an FD (Flexible Disk Drive), a CD (Compact Disc), and a DVD (Digital Versatile Disc).

  The communication board 915 is wired or wirelessly connected to a communication network such as a LAN (Local Area Network), the Internet, or a telephone line.

  The magnetic disk device 920 stores an OS 921 (operating system), a window system 922, a program group 923, and a file group 924.

  The program group 923 includes programs that execute the functions described as “units” in the embodiment. The program is read and executed by the CPU 911. That is, the program causes the computer to function as “to part”, and causes the computer to execute the procedures and methods of “to part”.

  The file group 924 includes various data (input, output, determination result, calculation result, processing result, etc.) used in “˜part” described in the embodiment.

  In the embodiment, arrows included in the configuration diagrams and flowcharts mainly indicate input and output of data and signals.

  In the embodiment, what is described as “to part” may be “to circuit”, “to apparatus”, and “to device”, and “to step”, “to procedure”, and “to processing”. May be. That is, what is described as “to part” may be implemented by any of firmware, software, hardware, or a combination thereof.

Embodiment 2. FIG.
A case will be described in which a package file is copied from a distribution destination terminal device to another terminal device, and image data is reproduced on the copy destination terminal device.

FIG. 10 is a schematic diagram of the image distribution system 100 according to the second embodiment.
The image distribution system 100 according to the second embodiment will be described below with reference to FIG.

  First, the configuration of the image distribution system 100 will be described.

The configuration of the image distribution system 100 is the same as that of the first embodiment (see FIG. 1). However, two package file playback terminal devices 400A and 400B are connected to the network 101.
The functional configurations of the file package terminal device 200 and the package file distribution server device 300 are the same as those in the first embodiment (see FIGS. 2 and 3).

The package file playback terminal devices 400A and 400B include a package file destruction unit 432 in addition to the configuration described in the first embodiment (see FIG. 4).
However, the package file reproduction terminal device 400B that is the copy destination of the package file 110 may not include the package file distribution server access unit 410, the package file distribution request unit 420, and the package file reception unit 421.
The package file destruction unit 432 will be described later.

  Next, an image distribution method of the image distribution system 100 will be described.

When distributing the package file 110, the package file distribution server device 300 adds “distribution destination device ID” to the DRM information 112 of the package file 110 in addition to the distribution login ID (FIG. 7, S250).
The distribution destination device ID is a device ID (for example, a MAC address) that identifies the distribution destination package file reproduction terminal device 400A. For example, the device ID of the package file reproduction terminal device 400A is notified to the package file distribution server device 300 together with the distribution login data when the user logs in to the image distribution service.

Here, it is assumed that the package file 110 distributed to the package file reproduction terminal device 400A is copied to the package file reproduction terminal device 400B.
For example, the package file 110 is copied between the package file reproduction terminal devices 400A and 400B by communication via the network 101 or using a storage medium (for example, a CD-ROM).

  The DRM information confirmation unit 431 of the package file playback terminal device 400B plays back the package file 110 when the user who plays the package file 110 is different from the user who downloaded the package file 110 and the package file 110 is copy-restricted. Not permitted (FIG. 8, S320).

The package file destruction unit 432 differs between the package file reproduction terminal device 400B and the distribution destination device ID (device ID of the package file reproduction terminal device 400A) included in the DRM information 112 of the package file 110. Destroy.
The destruction (destruction) of the package file 110 means that the image data 113 in the package file 110 cannot be reproduced, such as erasing (deleting) the package file 110 or deleting or rewriting the image data 113 in the package file 110. .

FIG. 11 is a table showing playback conditions for the package file 110 according to the second embodiment.
The playback conditions for the package file 110 in the second embodiment will be described below with reference to FIG.
When the distribution login ID and the reproduction login ID match, the DRM information confirmation unit 431 permits the reproduction of the image data 113 (item numbers 1 to 4).
When the copy permission data in the DRM information 112 indicates “copy permission”, the DRM information confirmation unit 431 permits the reproduction of the image data 113 (item numbers 5 and 6).
When the copy permission data in the DRM information 112 does not indicate “copy permission”, the DRM information confirmation unit 431 does not permit the reproduction of the image data 113 (item number 7).
If the copy permission data in the DRM information 112 does not indicate “copy permission” and the terminal ID of the self-playback terminal device does not match the distribution destination device ID in the DRM information 112, the package file destruction unit 432 stores the package file 110. Destroy (No. 8).

In the reproduction conditions of No. 4 and No. 7, the DRM information confirmation unit 431 rejects the reproduction of the image data 113 because the duplication permission data is “no duplication”, and the package file destruction unit 432 110 may be destroyed.
In the reproduction condition of item number 7, reproduction of the image data 113 may be permitted because the own reproduction terminal device and the distribution destination device match.

According to the playback conditions of FIG. 11, for example, playback of the package file 110 can be limited as follows.
If “paid user” is set as the permission confirmation method in the DRM information 112 of the package file 110 and “duplication not permitted” is set as the copy permission data, the image data 113 distributed for a fee is illegally copied between the terminal devices. However, the copy of the image data 113 is destroyed and cannot be used.

  In the first and second embodiments, for example, the following package file distribution system has been described.

The package file distribution system (image distribution system 100) includes a file package terminal device 200, a package file distribution server device 300, and a package file reproduction terminal device 400.
The file package terminal device 200 includes a package file generation unit 210 and a package file compression unit 220.
The package file generation unit 210 records inventory information and DRM information corresponding to the document / image file (image data 113) in a file packaged together with the document / image file (package file 110).
The package file compression unit 220 embeds permission authentication data (whether browsing is permitted, permission confirmation method, permission confirmation destination) in the package file 110 and compresses the file.
The package file distribution server device 300 includes a login inquiry unit 331 and a package file distribution unit 332.
The login inquiry unit 331 checks the login ID (distribution login ID) of the user who requested the file and permits distribution of the package file 110.
The package file distribution unit 332 transmits the package file 110 corresponding to the image distribution request to the package file reproduction terminal device 400 having an ID permitted by the login inquiry unit 331.
The package file reproduction terminal device 400 includes a DRM information confirmation unit 431, a package file destruction unit 432, and a package file reproduction unit 430.
The DRM information confirmation unit 431 extracts the DRM information 112 from the package file, and extracts duplication permission data in the extracted DRM information 112. If the copy permission data cannot be extracted (copy not permitted), the DRM information confirmation unit 431 determines that the DRM information 112 has been illegally changed, and identifies the package file 110 from which the DRM information 112 has been extracted.
The package file destruction unit 432 extracts the document / image file in the package file 110 specified by the DRM information confirmation unit 431, and destroys the extracted document / image file.
The package file reproduction unit 430 extracts a document / image file from the package file 110 when the DRM information confirmation unit 431 does not determine that it has been illegally changed. The package file playback unit 430 performs playback after converting the extracted document / image file into a format such as JPEG, MPEG, AVI, or TXT.

  The package file distribution system has the following effects, for example.

Unauthorized copying can be prevented by storing and saving image and moving image container files as packages including inventory and DRM information.
When the document is packaged, the attribute information can be stored together with the document body, and the disclosure restriction and feature extraction of the document can be performed.
It is possible to prohibit unconditional browsing by specifying whether or not browsing permission, permission checking method, and permission checking destination at the time of compression, and it can also be used as a page tag for collecting access logs.
Since authentication is performed on a file-by-file basis, even if the data is fragmented or destroyed, it is possible to authenticate as the same file by associating.
Document / image files and DRM information are packaged for those who copy or copy images by destroying or falsifying DRM information. Then, when the DRM information is extracted and changed, it is determined as an illegal process, the document / image file associated with the original DRM information is specified, and the document / image file is destroyed.
The document / image file is destroyed by deleting the individual data of the document / image file or adding random data to make the data file different from the original image data. This prevents the image from being copied.

Document maintenance efficiency is improved by storing and saving container files of images and moving images as packages including inventory and DRM information.
Since the database can be created with information extracted from inventory information, the application range can be expanded.
DRM information can be used for concealing personal information and confidential information in addition to preventing unauthorized copying.
By adding the generation of personal information and document attribute information as an option when packaging a document, the attribute information can be stored together with the document body, and the disclosure restriction and feature extraction of the document can be performed.
It is possible to prohibit unconditional browsing by specifying whether or not browsing permission, permission checking method, and permission checking destination at the time of compression, and it can also be used as a page tag for collecting access logs.
