Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computerized information processing management device that manages a computerized information processing device that processes computerized information recorded on a recording medium.

[0002]

2. Description of the Related Art Digital video discs (DVDs), compact discs (CDs), compact discroms (CDROMs), magnetic tapes, etc. are used for distributing copies of copyrighted works such as movies, music and games in the market. The recording medium may be used.

When a recording medium on which a copy of a work other than a movie is recorded is legally transferred, the transfer right does not have any effect on subsequent transfers. If a recording medium such as a CD on which music and games are recorded is no longer needed, a new purchaser
The recording medium can be sold to a used dealer.
Further, the second-hand seller can sell the recording medium to the customer.

However, when the computerized information of the duplicate is recorded on the recording medium, the quality hardly deteriorates even if the recording medium is repeatedly used for applications such as reproduction. This causes competition between the new market and the second-hand market. When a second-hand sale is made by a third party, the copyright holder or a distributor licensed by the copyright holder cannot recover the profit from the second-hand sale, so the investment capital can be recovered only by competing. It may not be possible.

Therefore, a new seller determines the selling price of a new item in anticipation that a second-hand sale will normally be made.
In order to anticipate a decrease in profit due to second-hand sales, new dealers surveyed the actual conditions of second-hand sales in advance, and estimated the number of second-hand goods sold and the selling price of second-hand goods.

Further, with respect to the copyrighted work of a movie, even if the recording medium on which a copy of the copyrighted work is recorded is legally transferred, the distribution right is given to the subsequent transfer. further,
For copyrighted works other than movies, even if a recording medium on which a copy of the copyrighted work is recorded is legally loaned, the right to lend is extended to further lending. It was confirmed by the survey whether or not second-hand sales and lending without permission were carried out.

[0007]

However, even if the seller is given the opportunity to determine the selling price of a new product that takes into account the decrease in profit due to second-hand sales, only part of the decrease in profit can actually be recovered. There are many.

[0008] If the selling price of a new product becomes inappropriately high because the profit decrease due to the second-hand sale is too large, the consumer's willingness to purchase decreases, and as a result, the new product cannot be sold. For example, when a debut work by a new singer or a new game is sold, there is no record of second-hand sales of products that are very similar to them, so the prediction is likely to be inappropriate. In this case, even if the survey predicts a large decrease in profit due to second-hand sales, it is very dangerous to add the decreased profit to the price of a new product.

Further, in order to understand all the actual conditions of second-hand sales, a great deal of labor, time and cost are required for the investigation. For this reason, although it is possible to estimate the number of sales and the selling price from some of the actual facts obtained by the survey, is there an illegal second-hand sale of the recording medium on which a duplicate of the movie work is recorded? In some cases, it may not be possible to confirm whether or not.

In addition, illegal second-hand sales and lending often do not become apparent unless the scale is considerably large. For this reason, it is preferable to prevent illegal second-hand sales and lending, rather than confirming them by investigation. However, if a large modification is made to the recording medium for that reason, a new product cannot be sold unless the modified recording medium has spread sufficiently.

The present invention has been made in view of such a situation, and a seller or the like conducts an investigation while suppressing illegal transfer or lending of a recording medium without making a large modification to the recording medium. It is an object of the present invention to provide a computerized information processing device that enables appropriate recovery of investment capital.

[0012]

The present invention employs the following means in order to achieve the above object.

The present invention comprises a medium additional storage means. The medium additional storage means is added to the recording medium in which the unique medium identification information is recorded, and is used to store the medium identification information and the target identification information unique to the permitted object permitted to use the recording medium.

Further, the acquisition means acquires the medium identification information recorded on the recording medium and the target identification information unique to the subject who is permitted to use the recording medium.

The processing management means then compares the medium identification information acquired by the acquisition means with the medium identification information stored in the medium additional storage means, and the target identification information and medium additional storage acquired by the acquisition means. Based on the comparison result with the target identification information stored in the means, it is determined whether or not the processing by the computerized information processing apparatus that processes the computerized information recorded in the storage medium is permitted.

Assuming that the medium additional storage means is added to the CD on which the electronic information of music is recorded, the electronic information processing device is, for example, a CD player. Then, the processing management means determines whether or not to permit the reproduction of the electronic information of music by the CD player. When the comparison result of the medium identification information indicates that the medium identification information matches, and the comparison result of the target identification information indicates that the target identification information also matches, the processing management means causes the CD player to digitize music information. Decide to allow playback of.

The object of permission and the object of permission to use the recording medium are electronic information processing devices such as a CD player and users who are permitted to use the CD.

That is, if the medium additional storage means added to the CD is different from the original one, or if the CD player or user who is trying to reproduce is different, the computerized information of the music recorded on the CD is read. Can't play.

Therefore, it is possible to prevent a recording medium such as a CD from being transferred or lent. Moreover,
There is no need to make major modifications to the recording medium to prevent it.

Further, when the permission information indicating that the target identification information stored in the medium additional storage means is permitted is given, the erasing means erases the target identification information stored in the medium additional storage means. To do. The permission information is provided by, for example, a new seller who has obtained permission from the copyright holder. If a new dealer collects the profit loss from second-hand sales when giving permission information, it is not necessary to investigate the actual situation of second-hand sales. Therefore, a new dealer or the like can properly recover the investment capital regardless of the investigation.

Is attached to the plastic case 2 to be added to the recording medium CD1. A ferroelectric memory or the like mounted on the wireless IC tag 3 can be used as the medium additional storage unit 31.

The medium additional storage means 31 is used to store medium identification information and device identification information. The medium additional storage unit 31 is provided with storage areas 311 and 312 for storing medium identification information and device identification information, respectively. The medium identification information is information specific to the CD 1 to which the wireless IC tag 3 is added, and is, for example, the product number or the manufacturing number recorded on the CD 1. Also, the device identification information is
CD that is permitted to play back the electronic information recorded on CD1
This is information unique to the player. The device identification information includes, for example, the product number of the CD player, the serial number, and the date of manufacture. In this example, it is assumed that only the device identification information of one CD player is stored in the storage area 312.

The control unit 32 reads out information from the medium additional storage unit 31 and writes (including erasing) information into the medium additional storage unit 31. The control unit 32 uses the input / output IF 33 to exchange various information with an external device such as a reader / writer device. The control means 32 uses the input / output IF3.
3 is made to transmit the information read from the medium additional storage means 31 to an external device. Further, the control means 32 stores the information received by the input / output IF 33 from the external device in the medium additional storage means 31.
Write in. The control unit 32 may be realized by, for example, a microprocessor mounted on the wireless IC tag 3 and a program stored in the memory cooperate with each other.

The input / output IF 33 has a modulation / demodulation circuit, an antenna, etc., and performs bidirectional communication with an external device in a non-contact manner. The electromotive force induced in the antenna of the input / output IF 33 is
It is used to operate the wireless IC tag 3.

In this embodiment, the reader / writer device is installed in a store of a rental company. When the rental fee is collected from the customer at the store, the clerk uses the reader / writer device to erase the device identification information from the medium additional storage unit 31, for example. That is, to the customer who paid the rental fee, the C to which the wireless IC tag 3 is added in a state where the device identification information is erased from the medium additional storage means 31.
D1 will be lent.

The computerized information of the music recorded on the CD 1 lent to the customer is reproduced by the CD player owned by the customer, for example. The CD player that performs the process of reproducing the computerized information of the music recorded on the CD 1 is a specific example of the computerized information processing device that processes the computerized information recorded on the recording medium.

As shown in FIG. 2, the CD player 4 is
A CD reproducing means 41 is provided. The CD reproducing means 41 is a CD
The information recorded on the CD 1 inserted in the player 4 is read, and the music is reproduced based on the read information. The CD reproduction means 41 performs reproduction processing according to an instruction from the control means 42.

The control means 42 comprises an acquisition means 44 for acquiring the medium identification information recorded on the CD 1 itself and the device identification information stored in the memory 43 of the CD player 4. The acquisition means 44 is, for example, the CD 1
The medium identification information recorded on itself is read, and the medium identification information is acquired. In addition, the acquisition unit 44 includes the memory 4
The device identification information is read from 3. Memory 43 is CD1
The device identification information that is provided in the CD player 4 that intends to play back music by using the CD player 4 is the device identification information of the CD player 4 that is permitted to use the CD 1.

Further, the control means 42 uses an input / output IF 45 capable of communicating with the input / output IF 33 of the wireless IC tag 3,
The medium identification information and the device identification information stored in the medium additional storage unit 31 are received from the wireless IC tag 3.

The medium identification information and the device identification information acquired by the acquisition means 44 and the medium identification information and the device identification information stored in the medium additional storage means 31 are stored in the process management means 4.
6 is supplied.

The process management means 46 compares the medium identification information acquired by the acquisition means 44 with the medium identification information stored in the medium additional storage means 31, and the device identification information acquired by the acquisition means 44 and the medium. The device identification information stored in the additional storage means 31 is compared. Then, the processing management means 46 determines whether to permit the reproduction processing by the CD reproduction means 41 based on the comparison result of the medium identification information and the comparison result of the device identification information.

When the comparison result of the medium identification information indicates that the medium identification information matches, and the comparison result of the device identification information indicates that the device identification information matches, processing management means 46 causes CD reproducing means 41 to perform the processing. Make a decision to allow the replay process. If the processing management unit 46 does not determine the permission, the control unit 42 does not instruct the CD reproduction unit 41 to perform the reproduction process.

When the comparison result of the medium identification information indicates that the medium identification information matches, and the comparison result of the device identification information indicates that the device identification information is different, the process managing means 46 stores the medium as additional storage. It is determined whether or not the storage area 312 of the means 31 has a free space. In this example, since only the device identification information of one CD player is stored in the storage area 312, if the device identification information is erased, the information received using the input / output IF 45 will be included in the device identification information. Is not included. Therefore, the processing management means 46 is
It is possible to determine whether or not there is a vacancy in the storage area 312 depending on whether or not the device identification information is included in the information received using F45. Then, the processing management means 4
6 determines to permit the reproduction processing by the CD reproduction means 41 even when it is determined that the storage area 312 of the medium additional storage means 31 has a free space. When it is determined that the storage area 312 of the medium additional storage unit 31 has a free space, the processing management unit 46 uses the input / output IF 45 to transmit the device identification information acquired by the acquisition unit 44 to the wireless IC tag 3. As a result, the transmitted device identification information is stored in the storage area 312, and then the processing management unit 46 determines permission.

The comparison result of the medium identification information indicates that the medium identification information is different, or the comparison result of the device identification information indicates that the device identification information is different, and the storage area 312 of the medium additional storage unit 31 stores it. When it is determined that there is no vacancy, the processing management means 46 does not determine permission. Even when at least one of the medium identification information and the device identification information stored in the medium additional storage unit 31 is not received by the input / output IF 45, the process management unit 46 does not determine permission.

Therefore, permission is determined for the computerized information of the music recorded on the CD 1 lent in the state where the device identification information is erased from the medium additional storage means 31. Further, as long as the same CD player as the one for which the permission is determined is used, the permission is also determined for the computerized information of the music recorded on the CD 1 in which the device identification information is stored in the medium additional storage unit 31. Done.

That is, a customer who rents a CD from a rental company can reproduce the electronic information of music recorded on the rented CD as many times as long as the same CD player is used. On the other hand, even if a customer who rents a CD from a rental company lends the CD to another person, if the customer does not use the same CD player, the other person,
It is not possible to reproduce the computerized information of music recorded on the rented CD.

A customer who has rented a CD from a rental company cannot effectively lend the CD to another person. Moreover, the CD itself need not be modified.

In order to reproduce the computerized information of music recorded on the rented CD on a different CD player, the device identification information needs to be erased from the medium additional storage means 31.

For example, the clerk of the rental company receives C from the customer.
When D is returned, the device identification information is erased from the medium additional storage unit 31 using the reader / writer device. Thereby, the rental company can lend the CD to other customers.

When a customer who rents a CD from a rental company wants to erase the device identification information from the medium additional storage means 31 in order to lend the CD to another person, permission of the rental company is required. It

For this reason, the rental company manages and operates a permitting device that permits the erasing of the device identifying information stored in the medium additional storage means 31. This permission device communicates with the terminal of the permission requester requesting permission by using, for example, a web server. As shown in FIG. 3, the terminal 5 of the permission requester is connected to the web server 6 through a telecommunication line 7 such as the Internet.

In the web server 6, customer information such as customer name, customer ID, customer password, and e-mail address of the customer who lent the CD, title name of the lent CD, management ID of the CD, A database 8 which is associated with lending information regarding lending such as lending start date and lending end date is connected.

The web server 6 transmits various input forms to the terminal in response to a request from the terminal 5 and performs a predetermined process on the information input in the input form.

The permission requester uses his / her terminal 5 to request the web server 6 for a permission application form for obtaining permission for erasing the device identification information stored in the medium additional storage means 31.

The permission application form has at least an input field for inputting customer information of the permission requester. The customer information of the permission requester entered in this entry field is posted from the terminal 5 to the web server 6. When the customer information of the permission requester is posted to the web server 6, the web server 6
Sends a collection form for collecting a permission fee for permitting deletion to the terminal 5. The collection form is provided with an input field for inputting, for example, a credit card number, an expiration date, and the name of the holder. The information regarding the credit card entered in this entry field is also posted from the terminal 5 to the web server 6. Then, by using the information about the credit card posted on the web server 6, it is confirmed whether or not the permission fee can be collected. If it is confirmed that the permit fee can be collected, the permit device 9
Issues permission information indicating permission to erase the device identification information stored in the medium additional storage unit 31. This permission information is, for example, a permission key in which numbers and alphabets are combined. Then, the e-mail in which this permission key is described is transmitted to the e-mail address used by the permission requester. The permission requester confirms the permission key described in the electronic mail on the terminal 5 or the like.

When the permission key is given, the erasing means 34 of the wireless IC tag 3 erases the device identification information from the medium additional storage means 31.

The permission requester inputs the permission key using the remote controller of the CD player 4, for example. When the permission key is input, the CD player 4 transmits the permission key to the wireless IC tag 3. The control means 32 of the wireless IC tag 3 supplies the received permission key to the erasing means 34. When the permission key is given, the erasing means 43 erases the device identification information from the medium additional storage means 31.

When the device identification information is erased from the medium additional storage unit 31, the medium additional storage unit 31 is in the same state as when the CD is lent by the rental company. That is, by using this computerized information processing management system, even if the license requester actually lends the CD to another person,
It is virtually the same as the one rented by a rental company. Even if the survey is not conducted, the rental company can collect the usage fee from the license requester.

When the authorization key is issued, the customer information and loan information in the database 8 are updated based on the information entered in the input form. For example, if an input field for changing the end date of the loan period is provided in the permission application form, the customer can extend the loan period by only inputting the end date in the input field.

Further, in the above-described first embodiment, the processing management means 46 is provided in the CD player 4, and the CD player 4
The side compares the medium identification information and the device identification information. However, the medium identification information and the device identification information can be compared on the wireless IC tag 3 side. In this case, the processing management unit 46 is realized on the wireless IC tag 3 side by, for example, a microprocessor mounted on the wireless IC tag 3 and a program stored in the memory in cooperation with each other. The processing management means 46 is connected to the wireless IC tag 3
The configuration of the computerized information processing management system provided on the side is shown in FIG. Further, flowcharts for explaining the operation of this computerized information processing system are shown in FIGS. In addition,

When the device identification information and the medium identification information from the D player 4 are received, the process management unit 46 reads the device identification information and the medium identification information from the storage areas 311 and 312 of the medium additional storage unit 31. Then, as shown in FIG. 6, the processing management means 46 compares the medium identification information acquired by the acquisition means 44 with the medium identification information read from the medium additional storage means 31, and determines whether the two match. It is determined (S11).

When the comparison result of the medium identification information indicates that the medium identification information is the same, the process management means 46 causes the device identification information acquired by the acquisition means 44 and the device identification read from the medium additional storage means 31. The information is compared to determine whether the two match (S12). On the other hand, when the comparison result of the medium identification information indicates that the medium identification information is different, the process management unit 46 does not permit the reproduction process by the CD reproduction unit 41. In this case, the processing of the wireless IC tag 3 ends.

When the comparison result of the device identification information indicates that the device identification information matches, the process management means 46.
Decides to permit the reproduction process by the CD reproduction means 41. When the permission is determined, the control means 32

When the reproduction instruction signal from the C tag 3 is received, the control means 42 instructs the CD reproduction means 41 to perform reproduction processing. On the other hand, if the reproduction instruction signal is not received from the wireless IC tag 3 while the CD player 4 is in the standby state, the control unit 42 does not instruct the CD reproduction unit 41 to perform the reproduction process and records it on the CD 1. The reproduced digitized information is not reproduced. At this time, the reason why the reproduction is not performed, such as a difference in the device identification information, may be displayed on the LCD or the like provided in the CD player 4.

In the above operation, the CD player 4
The operation is started when the CD1 is inserted into the CD, but the operation is not limited to this. Of course, the play button may be pressed, or the above operation may be performed at regular time intervals. Further, for example, when a plurality of music pieces are recorded on the CD 1, the above-described operation may be performed for each music piece. Further, in the above operation, if the reproduction instruction signal is not received while the CD player 4 is in the standby state, the reproduction processing instruction is not given to the CD reproducing means 41, but the operation is not limited to this. . For example, even if the reproduction instruction signal is not received while the CD player 4 is in the standby state, if the reproduction instruction signal is received before the state is repeated a predetermined number of times, the CD reproduction means 41 is instructed to perform the reproduction processing. May be performed.

Also, the wireless IC tag 3 and the CD player 4
When the communication is performed by and without contact, the communication content may be wiretapped by a malicious third party. When the communication content is eavesdropped, the medium identification information and the device identification information are leaked, which increases the possibility of misuse. Therefore, the wireless IC
Both the tag 3 and the CD player 4 are preferably provided with encryption means and decryption means.
