Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a player terminal using a public network for prohibiting reproduction and copying of distribution data unless charging for delivery of content data to the player terminal using a wireless network. The present invention relates to a copyrighted material distribution device and a copyrighted material transmission billing system.

[0002]

2. Description of the Related Art In recent years, with the development of network technology and digital technology, a system has been developed in which consumers can easily obtain music content information on their own terminals.

In such a system, a portable telephone network, a PHS network, etc. (hereinafter collectively simply referred to as a wireless network),
A method of distributing music using the Internet, for example, is generally used, but there is a problem in that content data having copyright, such as music content, is copied and transmitted to a third party.

[0004] As a method of preventing this, there is a mechanism in which the security of music contents is strengthened and only the person who directly purchases can make a copy.

For example, as shown in FIG. 16, a terminal 1 having a portable telephone (or PHS), a memory card, and a reproducing function is integrated into a content provider 2 via a wireless network 3 to make a call. Communicates with the provider 2,
Request a desired song by packet communication. When the music is requested, a telephone number of a terminal user who obtains the music content, a sub address indicating the music content, an ID number indicating the content of the content, and the like are also transmitted.

Then, the content provider 2 transmits the telephone number (a sub-address indicating music content and an ID number are added after the telephone number), the requested music (the music title,
(Composer, lyricist, etc.), and authenticates whether this ID number matches the registered ID number. Then, after this authentication, the request is accepted.

[0007] When the authentication is completed, the content provider 2 sends a fee corresponding to the requested music to a billing center (server), and the billing center sends the requested music content data to the terminal when the billing is completed. It was transmitting via a wireless network.

The main distribution center 5 periodically transmits the latest music content information to the content provider 2 by wire.

On the other hand, the following charging system has also been proposed. In this method, a user on the side of the terminal has a communication company (NTT) in advance.
It is assumed that a contract for downloading copyright data (music content) has been concluded in T). That is, the communication carrier acts as a proxy for the terminal.

[0010] That is, charging can be performed by incorporating information relating to charging of music content (to make it possible to know what music content the user requests) to the communication carrier.

For example, as shown in FIG. 17, a distribution user server 8a, a charging server 8b, and a charging management system 8c are provided in a charging center 8 in a communication carrier, and the distribution user server 8a authenticates a request from the terminal 1. Then, the music content is sent to the terminal, and the charging server 8b charges a fixed fee for the music content data to the line usage fee.

[0012] However, since the fee for music content varies depending on the fashion, a fee must be charged according to the type of music content to be distributed.
That is, the communication carrier needs to know the type of call, but generally, the communication carrier does not know the content of the call.

[0013] Therefore, the terminal 1 calls the communication carrier to listen to the music content and, if necessary, transmits information to the communication carrier to purchase the music content.
Then, the user again calls the communication carrier to transmit the music content. At this time, the communication carrier transmitted the music content and performed charging (log charging) in response to the authentication and the information that the music content was purchased.

[0014]

However, the above-mentioned method is a method in which the music content is transmitted to the terminal side and then billed. Therefore, when the music content is almost downloaded to the memory card on the terminal side, When the power is turned off, communication fails, but most of the data is actually downloaded.

That is, if the terminal is turned off immediately before the end of the distribution of the music content, the terminal is not charged and the profits and rights of the copyright holder and the content provider cannot be completely protected. .

In addition, if the music content is illegally stored in the memory card and then inserted into a third party terminal, the music content can be downloaded free of charge from the third party terminal. .
That is, unauthorized copying can be performed without restriction.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a player terminal, a copyrighted material distribution device, and a copyrighted material transmission and billing system which can reliably charge even a billing using a communication carrier.

[Table 1] Further, the reproduction / copy prohibition processing unit 16 of the terminal 10 writes the read prohibition flag Fp (copy prohibition, reproduction prohibition) in the secure area 41 (area where only a specific device can write) of the memory card 14. When storing these flags, a directory of music selection information (music selection name, music selection number) is generated and stored (d15).

On the other hand, after transmitting the billing information ki, the provider 11 transmits the music content data D of the music selection information Ai.
i is read from the HDD and compressed (d16).
(D17).

[0104] The terminal 10 receives the music content data Di and transfers it to the secure area 41 in the memory card 14.
Is encrypted using the "key" written in the data area 42, and then stored in the data area 42 (d18). The key written in the memory card 14 is desirably the telephone number of the terminal 10, the terminal ID, the password, or the like.

That is, the normal transmission method (PIAFS)
When an error occurs on the transmission path, the terminal returns a data retransmission request of the error part, and the receiving side stops storing in the memory until the requested data is returned, and stops monitoring sound etc. In the present embodiment, the terminal 10 is not provided with an error detection function at the time of transmission, and even if an error occurs during transmission, the error is stored in the memory card as it is. At this time, the interruption of the monitor reproduction sound is restored when the quality of the transmission path is restored.

Therefore, as shown in the sequence of FIG. 7, the reproduction processing unit 78 of the terminal 10 calculates CRC data (data for error detection) (d19) and transmits this to the content provider (d20).

On the other hand, the reproduction processing section 78 of the provider 11
Is associated with the transmission of the music content data Di,
Is stored (d21), collation with the CRC data from the terminal is performed (d22), and the error occurrence position is stored.

Next, when all data has been transmitted (d23), the provider 11 transmits a transmission end notification to the terminal (d24).

Then, a retransmission sequence of the music content data Di described below is performed. When an error occurs on the transmission line, the provider 11 sets only the error portion to H.
It is extracted from the DD, compressed and retransmitted (d26).

The terminal 10 deletes the error part in the memory card 14 and writes retransmission data in this part (d2
7).

Next, the terminal 10 calculates the CRC (d2
8) Reply this to the content provider (d2
9).

The provider 11 stores the retransmission data for the transmission error check (d30), and compares this data with the returned CRC data to determine whether there is a transmission error (d31).

When the provider 11 determines that there is no transmission error (d32), it sends a data retransmission end notification to the terminal side (d33).

Then, a call disconnection sequence starts. In this sequence, as shown in FIG. 7, a disconnection request is transmitted from the terminal 10 to the provider 11 (d35), and the provider 11 sends an open signal to the terminal 10 (d3).
6). As a result, the line between the terminal 10 and the provider 11 is disconnected.

Next, the terminal 10 stores the music content data D
When the line with the provider 11 is disconnected after downloading i (after downloading retransmission data in the case of an error), the charging center of the communication carrier is automatically sent to the charging center of FIG.
Place a call as shown in. This is performed by the line automatic disconnection / connection instruction processing unit 17.

The terminal 10 adds the ID of the terminal 10 and the user's password after the telephone number of the charging center 12 to the EEPRO.
Read from M32 and transmit to charging center 12 (d
40).

At this time, if the charging center 12 is busy, an automatic call is made after a predetermined time.

The accounting center 12 performs authentication based on the ID of the terminal 10 and the password of the user sent from the terminal 10 (d41), and transmits a call setting acceptance notification to the terminal after the authentication is completed (d42). , And enters a charging information transmission sequence.

In the charging information transmission sequence, the terminal 10 converts the charging information ki of the EEPROM 32 into music information,
The content sales ID and the content coding specification are transmitted to the center 12 as billing data kr (d4
3).

The center 12 registers the accounting data kr from the terminal 10 in association with the telephone number of the user of the terminal 10 (d44), and notifies the data reception (the accounting completion notification Ri).
Is transmitted to the terminal 10 (d45).

Then, the terminal 10 deletes the read prohibition flag Fp in the secure area 41 of the memory card 14 (d
At the same time, a disconnection request is made to the center (d4).
7) The line is released (d48). This is the terminal 10
Is configured as shown in FIG. 3, the reproduction permission instruction processing unit 19,
This is performed by the line automatic / disconnection instruction processing unit 17.

That is, in the first embodiment, the center 1
2 that the terminal 1 for the music content that was indeed purchased
Unless the terminal 10 is notified that the user 0 has been charged (final billing), the music content data of the terminal 10 cannot be reproduced, and can be reproduced after the main billing is completed. This protects the interests of music distribution manufacturers and copyright holders.

As a result, as shown in FIG. 9, when the communication carrier reaches the cut-off date of the call charge, the communication charge is added to the ordinary call charge settlement from the distribution history to the distribution charge. For example, distribution fees are charged to users, and debits are deducted from each user's bank account and distributed to copyright holders, providers, and communication carriers.

Also, the provider 11 of the first embodiment
Communicates with the terminal 10 by connecting the mobile phone 60. However, as shown in FIG. 10, the computer has the function of the mobile phone and the program configuration of FIG. Communication with the terminal 10 may be performed.

Although the charging information Ki is stored in the EEPROM, the charging information ki may be stored in the secure area 41 of the memory card 14.

<Second Embodiment> Next, a sequence of copying between users using a general public network will be described as a second embodiment. This copying between users is performed when the line is not connected to the provider 11 or when the user wants to download the same music as the partner terminal.

In the second embodiment, both the transmitting and receiving terminals mutually agree on the music to be copied.

In the case of terminal-to-terminal copy using the general public network, each terminal uses an operation key to set the terminal-to-terminal copy mode using the general public network to a computer (CPU).
30), and the communication number mp and telephone number of the communication partner for terminal-to-terminal copying using the general public network are set to EEPR.
Set to OM. This password mp is different from the password for public download.

This is because it is not possible to provide a third party with a password for public download in order to maintain security, so that the user can set the terminal without permission. Also,
Immediately before copying between users, the users (especially those receiving the download) tell the other party the password, and can change the password after the download is completed.

FIG. 11 is a system configuration diagram of terminal-to-terminal copying using a general public network. 12 and 13 are sequence diagrams.

First, a call control sequence between the terminal 10a and the terminal 10b will be described. The user of both terminals 10a and 10b uses the operation keys to set the computer (CPU 30) to be in the terminal-to-terminal copy mode using a wireless network, and to have their mutual identification numbers mp1, mp2 and telephone numbers H1, H.
2 is set in advance. Also, music information ai (comprising a music title, an artist name, etc.) required by the copy destination is registered (d.
50).

The registration of the music information ai can be performed immediately after the transmitting terminal makes a call and receives the call setting acceptance.

Then, the terminal 10a on the transmitting side calls the terminal 10b on the receiving side with a telephone number and makes a call (d5).
1) The call setting information is transmitted (d52). In the call setting information, the transmission capability, the telephone number, the personal identification number (mp1, mp2) of the terminal 10b, the type of the distribution service, and the like are transmitted after the telephone number.

Next, the terminal 10b on the receiving side has a transmission capability,

4).

That is, it is confirmed that the passwords mp1 and mp2 of both users performing the terminal-to-terminal copy and the terminal-to-terminal copy distribution are to be prevented from being downloaded to another terminal due to a wrong telephone call or the like.

At this time, if a password different from the password of the terminal-to-terminal copy is transmitted, transmission of the call setting acceptance is prohibited.

Next, the terminal 10a on the transmitting side transmits the billing information tki of the music information ai (a1, a2,...) (D56).

[0138] Receiving terminal 10b receiving this billing information tki, in the same manner as in the first embodiment, sets read-out prohibition flag Fp (copy prohibition) in secure area 41 (area in which only a specific device can be written) of memory card 14b. , Playback prohibited)
Is written for each piece of music information. When storing these flags, a directory of music selection information (music selection name, music selection number) is generated and stored, and charging information tki is stored in the EEPROM.
Is written (d57).

On the other hand, terminal 10a on the transmitting side transmits billing information t.
After transmitting the ki, the music content data Di for each piece of music information ai is read from the memory card and compressed (d58), and transmitted to the terminal 10b (d59).

The terminal 10b stores the music content data Di
Is encrypted using the “key” written in the secure area 41 in the memory card 14b, and then stored in the data area 42 (d60).

Next, the terminal 10b calculates CRC data (error detection data) (d61), and transmits it to the transmitting terminal 10a (d62).

On the other hand, every time the music content data Di is transmitted, the terminal 10a saves the CRC calculation result of the data (d63), compares it with the CRC data from the terminal 10b (d64), and determines the error occurrence position. Save.

Then, all music content data Di
When the transmission is completed, the terminal 10a on the transmission side transmits a transmission end notification to the terminal (d65).

If an error occurs on the transmission line,
The transmitting terminal 10a extracts only the error part from the HDD, compresses the error part, and retransmits the compressed part (d66).

The receiving terminal 10b is connected to the memory card 14
The error part in b is erased, and retransmission data is written in this part (d67).

Next, the terminal 10b calculates the CRC (d6
8) Reply this (d69). Sending terminal 10a
Stores retransmission data for transmission error check (d70), and compares this data with the returned CRC data to determine the presence or absence of a transmission error (d71).

When it is determined that there is no transmission error (d72), the terminal 10a transmits a data retransmission end notification to the terminal (d73).

When the data retransmission end notification (or data end notification) is received by the receiving terminal 10b, the receiving terminal 10b immediately transmits a disconnection request to the terminal 10a (d7).
4), the terminal 10a sends an open signal to the terminal 10b (d75).

Next, the terminal 10b on the receiving side disconnects the line with the terminal 10a after downloading (copying) the music content data Di from the terminal 10b on the transmitting side, and automatically connects to the charging center 12 of the communication carrier. A call is made as shown in FIG.

After the telephone number of the charging center 12, the terminal 10b indicates the ID of the terminal 10b, the password of the user (for terminal copy using a wireless network), and the type of distribution (the terminal-to-terminal copy using a wireless network). ID) is transmitted to the charging center 12 (d80).

At this time, if the charging center 12 is in a busy state, an automatic call is made after a predetermined time.

The charging center 12 authenticates whether the terminal is permitted to copy between terminals based on the ID of the terminal 10b sent from the terminal 10b and the password of the user (d81a). Transmits a call setting acceptance notification to the terminal 10b (d81b), and the terminal 10b
From the charging information tki of the EPROM, the song information, the content sales ID, and the content coding specification are converted to the charging data tk.
It is transmitted to the center 12 as r (d82).

The center 12 registers the accounting data tkr from the terminal 10b in association with the telephone number of the user of the terminal 10b (d83), and transmits a data acceptance notification (accounting completion notification Ri) to the terminal 10b (d84). ).

The terminal 10b clears the read prohibition flag Fp in the secure area 41 of the memory card 14 (d85), makes a disconnection request (d86), and releases the line (d87).

That is, in the second embodiment, when a copy of music content data is received from terminal 10a on the transmission side, even if music content data on terminal 10a on the transmission side is downloaded to a memory card, the downloaded content is The reading of the music content data is prohibited so that the reproduction cannot be performed, and the reading prohibition is released only after the charging center of the communication carrier notifies the user of the receiving terminal 10b that the charging of the copied music content data is completed. Thus, the copied music content data can be reproduced.

Further, since music content data can be transmitted only from the transmission side to the reception side, only the charged music content data is transmitted, and only the music content data to be transmitted is transmitted by the transmission side. .

<Third Embodiment> In the third embodiment, when users having terminals having this function are close to each other, each other's music content data is copied using a dedicated cable (RS-232C or the like) ( Hereinafter, it is simply referred to as terminal-to-terminal copy).

FIG. 14 is a system configuration diagram of the third embodiment, and FIG. 15 is a sequence diagram of copy between terminals.

In Embodiment 3, terminal 10a and terminal 1
0b is a dedicated cable, and the terminal 10a is a transmitting side and the terminal 10b is a receiving side.

In the case of terminal-to-terminal copy, each terminal sets the terminal-to-terminal copy mode in the computer using the operation keys, and sets the personal identification number vp and terminal ID of the communication partner for terminal-to-terminal copy. Set in EEPROM. The personal identification number vp is uniquely set by the user between the terminals for copying between the terminals as in the second embodiment.

The users of both terminals 10a and 10b use the operation keys to set the computer CPU 30 to be in the terminal-to-terminal copy mode using the dedicated cable, and set their mutual passwords vp1 and vp2. In addition, a standby state such as registration of music information ai (comprising music names, artist names, etc.) required by the copy destination is set (d9).
0, d91).

Then, the song (memory card 14a) that the terminal 10a on the transmitting side may copy to the receiving side 10b for transmission.
Is selected (d93). In this case, a menu of the downloaded music is displayed on the display unit to select music.

Next, the transmitting terminal 10a sends an authentication request command to the receiving terminal 10b (d94). Upon receiving the authentication request command (the personal identification number vp1 and the terminal ID of the terminal 10a), the receiving-side terminal 10b returns its own terminal information (the personal identification number vp2 and the terminal ID of the terminal 10b) (d95).

The transmitting terminal 10a performs authentication (mutual authentication).
(D96), and if the authentication is successful, the accounting information fki for copying between terminals is transmitted (d97). The billing information fki includes a song title, a date, a time, a password of the receiving side,
This is the password of the sender, the sales company, and the like.

Next, the terminal 10b on the receiving side sets the billing information f
In accordance with the reception of the ki, the read prohibition flag Fp (copy prohibition, reproduction prohibition) is written into the secure area 41 (area writable only by a specific device) of the memory card 14b for each piece of music information (d98).

On the other hand, terminal 10a on the transmitting side transmits billing information f
After transmitting the ki, the music content data Di for each piece of music information ai is read from the memory card 14, compressed and transmitted to the terminal 10b (d99).

The terminal 10b stores the music content data Di
Is encrypted using the “key” written in the secure area 41 in the memory card 14b, and then stored in the data area 42 (d100).

Next, when the transmission of the music content data Di is completed, the terminal 10a sends a data transmission end notification to the terminal 10b. It is considered that retransmission of the error data is unnecessary because it is a wire unlike wireless.

Then, when the transmission of all the music content data Di is completed, the terminal 10b on the receiving side makes a call to the charging center of the communication carrier by using a wireless network to set up a call (d110). In this call setting, the type of distribution (copy between terminals) and the password vp2 of the terminal 10b are transmitted after the telephone number of the charging center.

The charging center 12 authenticates whether or not the terminal is permitted to copy between terminals based on the ID of the terminal 10b sent from the terminal 10b and the password of the user (d111). Transmits a call setting acceptance notification to the terminal 10b (d112).

The terminal 10b stores the accounting information f in the EEPROM.
From the ki, the music information, the content sales ID, the content coding specification, the password number vp2, and the like are transmitted to the center 12 as billing data fkr (d113).

The center 12 registers the accounting data fkr from the terminal 10b in association with the telephone number of the user of the terminal 10b (d114), and transmits a data acceptance notification (accounting completion notification Ri) to the terminal 10b (d115). ).

Then, the terminal 10b sets the read inhibition flag Fp, EEPRO in the secure area 41 of the memory card 14.
The accounting information fki of M is deleted (d116), a disconnection request is made (d117), and the line is released (d11).
8).

That is, even in the case of terminal-to-terminal copy using a dedicated cable, reproduction is not permitted unless the charge of the copy music is charged to the user of the copy destination terminal on the communication carrier side. .

In each of the above embodiments, the system for distributing music has been described. However, the present invention is not limited to music, and may be video.

Further, in each of the above embodiments, the terminal has been described using a memory card. However, the terminal of the present invention may be provided with a memory card without the memory card and capable of real reproduction.

[0177]

As described above, according to the player terminal of the present invention, after requesting distribution of content data to a higher station of distribution, distribution of the content data from the higher station of distribution to the player terminal is performed. Is transmitted, the access to the area for storing the content data is prohibited, and the distributed content data is stored in the area.

Since the line is connected to a higher-ranking station for charging and the prohibition state is released after charging, the desired content data cannot be reproduced without charging. ing.

Further, since the user is not charged unless all the content data is normally downloaded to the terminal, a charging trouble at the time of a download failure can be avoided.

That is, since the contents data cannot be illegally reproduced, it is possible to protect the interests of the copyright holder, the distribution company, and those involved in the industry such as sales.

In particular, when the player terminal has a memory card, before setting the read-out prohibition flag and the charging information in the secure area of the memory card before receiving the distribution of the desired content data, the distribution of the content data is started. The encrypted content data is written in the data area below the secure area using the terminal's telephone number, ID, and the like.

Then, when a charge completion notification is received from the higher-order station for charge, the read prohibition flag is released.

That is, even if the memory card is handed over to another person, since the other person does not know the ID of the player terminal or the like, it cannot be reproduced, and even if the memory card is removed after downloading, the secure area of the memory card is prohibited from being read. , The effect of not being able to reproduce is obtained.

Furthermore, when copying to the other party via a network or by connecting a dedicated line, before transmitting the content data to be copied to the other party, the reproduction area of the newly downloaded area in the receiving memory is prohibited. After that, the data is encrypted with the unique number of the transmission side, and the transmission side sends the data to the other side to download.

Then, after downloading, the other party automatically connects the line to the higher-level station for charging instead of the transmitting side, sends a charging permission notification, and releases the reproduction inhibition state when receiving the notification of completion of charging from the higher-level station for charging. By allowing the downloaded content data to be played back, an effect is obtained that it is possible to reliably charge even for copying between terminals via a network.

Further, according to the content data charging system including the upper station for distributing the content data, the higher station for charging provided in the communication carrier, and the player terminal using the public network, Before delivery of the content data in response to the request, the content is encrypted as a playback prohibition state, and when there is a notification of the completion of charging from the higher-ranking station, the reproduction prohibition is released and the charge for charging is automatically distributed and notified. As a result, the rights and benefits of the sage sages can be appropriately protected.
