Authentication method, which is a method of receiving authentication, a payment ID required for charging a fee such as a password and ID issuance, a payment method, and a registration date and an update date as a log of the user information. , Hold the user's position.

Step 103) After the content right holder registers the right information of the content,
The rights holder terminal 10 is used to convert the contents and rights information into data.
From 0, a content ID issuance request is made.

Step 104) Copyright management device 300
Receives content and right information, and performs a content ID registration process in the registration unit 320. This processing will be described with reference to FIG.

The copyright management device 300 inputs attributes and uploads contents (step 100).
1). The ID issuing unit 310 of the copyright management device 300 issues a processing ID that is a temporary content ID (step 1).
002), the rights information and the contents are provisionally stored (step 1003). After that, the content ID and license ID are assigned to the content in the content check unit 330.
Check whether a digital watermark is included (step 10
04), if a watermark is included (step 100)
4, Yes), and notifies the right holder by e-mail (step 1005), and discards the temporarily stored contents (step 100).
6). If there is no watermark (step 100
4, No), it is possible to confirm the new registration for which the content ID registration process has not been performed before, and to confirm that the content is different from the previously issued content, a hash value of the content is obtained, and If there is a content hash value that is the same as the content hash value (step 1007, Yes), the right holder is notified (step 1008), and it is checked again whether the content hash value is the same (step 1010). If the reply of the right holder is not registered (step 1011), the temporarily stored contents are discarded (step 1012). In this content identity check, if there is no identical content (step 1007,
No subject), the main registration process starts (step 1013),
The content ID is issued, the right information is registered in the right information DB 362 as shown in Table 4, and the content DB 36
6, the copyright management device registers the content storage location, stores the content in that location, and ends.

Then, the content ID is registered in the issuance log DB 363 shown in Table 5, and the content ID registration process ends.

[0050]

[Table 4] Table 4

[0051]

[Table 5] Table 5 Step 105) Offline contract processing is performed between the right holder and the right user.

Step 106) The rights user is authenticated by the copyright management device 300, and performs the license ID registration process in accordance with the license agreement.
When D, the license information, and the distribution information are received from the right user, the ID issuing unit 310 performs a license ID issuing process. The license ID issuing process will be described with reference to FIG.

The license ID registration process is performed by the ID issuing unit 3
In step 10, first, a content ID and a distribution attribute are input. If the content is not stored in the copyright management device 300, a content upload (including an access key) is performed (step 2001).
A process ID of D is issued (step 2002), and each information is temporarily stored. The reason why the license ID registration processing is being performed is transmitted to the right holder by e-mail. If the right holder confirms that the right user has performed the registration processing correctly (step 2003, OK), the registration is OK. If not (step 2005, NG), NG is returned (step 2004), and the temporarily stored content is discarded. If the registration is OK, the license ID is issued, the license information corresponding to the license ID is registered in the license information DB 364 as shown in Table 6, and the distribution information is registered in Table 7
As shown in (1), the information is registered in the distribution information DB 365 (step 2009).

[0054]

[Table 6] Table 6

[0055]

[Table 7] After that, using the content ID as a key, the content stored in the copyright management device 300 is embedded in the content as a digital watermark by linking the content ID and the license ID, and the copyright management device provides the provided content DB 367. The content storage location with the watermark is registered, the content is stored in that location, and the right user can download the content, and the process ends.
(Step 2010).

Step 1007) A license ID issuance confirmation mail is transmitted from the copyright management device 300 to the right user terminal 200.

After the license ID registration process, the license ID is registered in the issue log DB 363. The rights user can download the watermarked content.

Step 1008) Right user terminal 20
0 downloads the license ID and the content with a digital watermark from the copyright management device 300.

Next, the contents are transferred to the copyright management device 300.
The case where the file is not saved will be described.

FIG. 8 is a sequence chart when the content is not managed by the copyright management device according to the embodiment of the present invention.

Step 201) Registration processing of the right holder user is performed so that the right holder can access the copyright management device 300. This is the same as the case of saving, and the items in the user DB 361 are the same as those in Table 4 described above.

Step 202) Right user terminal 200
Thus, the user of the right user is registered in the right management device 300.

Step 203) The content right holder is authenticated to register the content right information.
The right holder terminal 100 issues a content ID issuance request using the content and right information as data.

Step 204) Copyright management device 300
On the side, the content and the right information are received from the right holder terminal 100, and the content ID registration process is performed. Up to this point, it is almost the same as the case of saving, and the only difference is that the content is not saved. This can be indicated by registering in the content DB 366 that the content storage location is “owned by the right holder” or the like and that the copyright management device owns the right holder.

Step 205) Next, an off-line contract is made between the right holder and the right user.

Step 206) After the conclusion of the contract, the right holder terminal 100 transmits the right holder access key, the right user, and the license condition to the copyright management device 300.

Step 207) The copyright management device 300 receives it, and the access key generation unit 340 generates a right user access key. The right user access key is used to access the right user among the items of the license information (Table 6 described above) and the distribution information (Table 7 described above) in accordance with the right user user ID and the user license conditions. This is the information that masks the place where is not allowed. The generation of the right user access key will be described with reference to FIG.

The access key generation unit 340 of the copyright management device 300 firstly obtains the right holder access key and the content I
D, an input of a license right, a use condition, and a use method are received (step 3001), and then the content ID registered by the right holder is obtained from the right holder access key in step 300.
It is checked whether the content ID input in step 1 is included (step 3002). If the content ID is detected (step 3002, Yes), masking / non-masking is set according to the permission right, usage conditions, and usage method restriction, and a right user access key is generated (step 3003). The generated access key is transferred to the right holder terminal 100
(Step 3004) and the process ends.

[0069] The generated access key is transmitted from copyright management device 300 to right holder terminal 100. Here, the access key will be described. FIG. 10 is a diagram for explaining an access key according to one embodiment of the present invention. An access key for a rights holder has access to rights information,
It can generate a partially accessible key.
The right user access key is a key that can be partially accessed. In the example shown in the figure, a case is shown in which the duplication right is permitted and only the excerpt is permitted. In the figure, a mask item shown in black indicates that setting is not possible, and a non-masked item shown in white indicates that the right user can specify the item.

Step 208) The rights holder terminal 100
The content with the signature ID and the access key are transmitted to the right user terminal 200.

Step 209) The right user is authenticated by the copyright management device 300. Step 210) Then, in order to make a license ID registration request in accordance with the license agreement, the copyright management device 300 uploads the content from the right user terminal 200, and transmits the content ID, the license information, the distribution information, and the rights usage. When the user access key is received from the right user terminal 200, a license ID issuance process is performed.

The details of the license issuance process are the same as in the case of storing the content. The difference is in the embedding of the electronic watermark. This is a process in which the content ID and the license ID are linked to the uploaded content. It is about to be embedded in the content as a digital watermark.

(Step 211) Then, the storage location of the watermarked content is registered in the provided content DB 367, and the rights user terminal 200 is allowed to download the content, and the process ends.

After the license ID registration processing, the license ID is registered in the issue log. In addition, the right user can download the watermarked content.

FIG. 11 shows an example in which no content is stored in the copyright management device according to the embodiment of the present invention. The numbers in the figure correspond to the numbers in parentheses below.

(0) The right user (Company I) issues a right user access key “0” to the copyright management device 300.
