That is, a case will be described in which a digital card unnecessary for the user of the portable terminal 11 and a digital card unnecessary for the user of the portable terminal 12 are exchanged. FIG.
5 is a flowchart for explaining a digital card exchange operation. Here, it is assumed that the mobile terminal 11 and the mobile terminal 12 are close to each other.

The portable terminal 11 and the portable terminal 12 are connected (step S41). The connection form may be a wired connection using a connection medium such as a cable, or a wireless connection in which terminals are directly connected wirelessly. In the case of wireless connection, for example, a connection technology based on Bluetooth may be used. Then, the exchange program installed in the mobile terminal 11 and the mobile terminal 12 is started.

In the portable terminal 11 and the portable terminal 12, the control unit 110 transmits / receives a message for connection to / from another portable terminal via the terminal connection unit 114, thereby establishing a connection operation with the other terminal. Perform (Step S42).
That is, the mobile terminal 11 and the mobile terminal 12 perform a connection operation by transmitting and receiving a message for connecting to each other.

The user of the portable terminals 11 and 12 inputs the digital card exchange condition (step S43). The exchange conditions include the type of digital card to be exchanged (unnecessary) and the type of card to be acquired from the other party. Then, in the mobile terminals 11 and 12, the control unit 110 transmits and receives exchange conditions to and from the other mobile terminals via the terminal connection unit 114. That is, the exchange conditions are transmitted and received between the portable terminal 11 and the portable terminal 12.

In the portable terminal 11 and the portable terminal 12, the control unit 110 determines whether or not the exchange conditions presented by both users match (step S44). That is, it is determined whether the digital card that the user of the portable terminal 11 wants to exchange matches the digital card that the user of the portable terminal 12 wants to exchange. As a result, if they match,
The exchange operation is continued, and if they do not match, the exchange operation ends.

In the portable terminals 11 and 12, the control unit 110 transmits and receives a digital card exchange request to and from the other terminal via the terminal connection unit 114 (step S45). In the mobile terminal 11 and the mobile terminal 12,
The control unit 110 reads the digital card to be exchanged from the storage unit 112, transmits the digital card to the other portable terminal via the terminal connection unit 114, and transmits the digital card transmitted from the other portable terminal via the terminal connection unit 114. The card is received (step S46). In other words, the exchange of the digital card to be exchanged is performed between the portable terminal 11 and the portable terminal 12. Then, in the mobile terminal 11 and the mobile terminal 12,
The control unit 110 stores the received digital card in the storage unit 1
12, and transmits a received message to the other terminal via the terminal connection unit 114 (step S47).

In the portable terminals 11 and 12, the control unit 110 receives the received message from the other portable terminal via the terminal connection unit 114, and first (step S4).
6) It is determined whether the digital card transmitted to the other portable terminal is subject to copyright protection (step S48). Whether the digital card is subject to copyright protection is determined based on the copyright protection information stored in the storage unit 112. As a result, if the digital card transmitted earlier is subject to copyright protection, the control unit 11
0 deletes the information on the digital card stored in the storage unit 112 (step S49). Specifically, this is performed by outputting a data erasure command to the storage unit 112 regarding the digital card. If the digital card transmitted earlier is not the object of copyright protection, the exchange operation is terminated. Here, the case where the information on the digital card stored in the storage unit 112 is deleted when the data is subject to copyright protection (steps S48 and S49) has been described as an example. Regardless, the information about the digital card may be deleted.

Next, a description will be given of the operation in the case where a competitive game is played between the portable terminal 11 and the portable terminal 12 using a digital card. FIG. 8 is a flowchart for explaining the operation of the battle game. Here, too, it is assumed that the mobile terminal 11 and the mobile terminal 12 are close to each other.

The portable terminal 11 and the portable terminal 12 are connected (step S51). The connection form may be a wired connection using a connection medium such as a cable, or a wireless connection in which terminals are directly connected wirelessly. In the case of wireless connection, for example, a connection technology based on Bluetooth may be used. Then, a game program incorporated in the mobile terminal 11 and the mobile terminal 12 for playing the battle game is started (step S52).

The user of the portable terminal 11 or the portable terminal 12 selects an arbitrary card from the digital cards stored in the terminal (step S53), and uses the selected digital card for a match. In the mobile terminals 11 and 12, the control unit 110 transmits and receives information of the selected digital card via the terminal connection unit 114 (step 54). That is, the portable terminal 11 and the portable terminal 1
2 transmits / receives information of the selected digital card to / from each other. Then, in the mobile terminals 11 and 12, the control unit 110 causes the digital card selected by the other mobile terminal and the digital card selected by the own mobile terminal to be displayed on a display unit such as a liquid crystal panel.
That is, the mobile terminal 11 and the mobile terminal 12
The digital card on the own side and the digital card selected on the other terminal are displayed.

Here, the rules of the battle game will be described. As a component of the fighting game, for example, a special technique (kick, punch, etc.) to attack the opponent
And guards to protect yourself against attacks from opponents. These special moves and guards can be used within the range of the points (life points) of each digital card. For example, if you need 30 points to kick, 20 points to punch and 5 points to guard, use a kick, punch and guard when the life point is 50 points. You can do it, but you have 20 life points
At the point, the punch and the guard can be used, and when the life point is 5 points, only the guard can be used. At the time of the battle, the card having the life point of 0 is lost.

The users of the portable terminals 11 and 12 play a battle game based on the points of the digital card selected by the user (step S55). Specifically, it is performed in the following manner. The user of the portable terminal 11 selects an arbitrary special move from among the special moves to attack the digital card of the user of the portable terminal 12. The control unit 110 in the mobile terminal 11 reduces points corresponding to the selected special technique from the digital card of the user of the mobile terminal 11. The control unit 110
The mobile terminal 12 is notified of information on the selected special technique. In other words, information on what kind of deadly technique has been selected on the mobile terminal 11 side is notified. The user of the mobile terminal 12 can respond to an attack from the mobile terminal 11 by using a special technique or a guard. The control unit 110 in the mobile terminal 12 reduces points used for the special technique and the guard from the digital card of the user of the mobile terminal 12. If the mobile terminal 12 does not respond to the mobile terminal 11, the digital card of the user of the mobile terminal 12 is damaged by an attack from the mobile terminal 11, and the control unit of the mobile terminal 12. 11
A value of 0 reduces points corresponding to damage from the digital card of the user of the portable terminal 12.

The control unit 11 of the portable terminal 11
0 increases or decreases the number of points on the digital card of the user of the portable terminal 11 according to the match result (step S5).
6). The same applies to the mobile terminal 12 (step S56). For example, when the portable terminal 11 wins, the control unit 110 of the portable terminal 11
A prescribed point is given to the digital card of one user. Further, the control unit 110 of the mobile terminal 11 makes an inquiry to the mobile terminal 12 to award the points held by the digital card of the user of the mobile terminal 12 at the beginning of the battle to the digital card of the user of the mobile terminal 11. Is also good.

As described above, by replacing a replaceable card such as a trading card with a digital card, the card provider can sell the digital card through the Internet 100. Since the user can purchase a digital card from the Internet 100 and store the digital card as data inside the portable terminal,
Digital cards can be easily managed. Therefore, even if the number of digital cards held increases due to a new purchase or the like, the management becomes easy. Therefore, occurrence of a situation such as loss or theft of the card can be prevented.
In addition, since the digital card is stored as data in the portable terminal, the card is not deteriorated, so that the replacement value of the card due to use can be prevented from being reduced.

By digitizing a trading card or the like, not only image information and points but also audio information and the like can be added to the card. Therefore, the entertainment value of the card can be improved as compared with a conventional card to which only image information and points can be added. For example, not only an image of an animation character but also a sound or the like can be added to a card.

Further, by moving the digital card between the portable terminals, the digital card can be exchanged between the portable terminals, so that the circulation of the digital card can be promoted. If the digital card is subject to copyright protection, data related to the digital card is deleted from the source terminal, so that such a digital card is prevented from being stored in a plurality of mobile terminals. Can be. Further, the digital card is stored in the storage unit 112 in which copyright protection measures are taken. Therefore, even if the storage unit 112 is attached to another device, the data stored in the storage unit 112 cannot be decoded. Therefore, illegal copying of the digital card between the terminals can be prevented.

In the above-described embodiment, a case has been described in which a digital card is exchanged and a battle game is played in a state where the portable terminals are connected at a short distance. However, a network (telephone line, Internet 100) is used between the portable terminals. )
, A digital card exchange and a battle game may be performed in a state where the game is connected via the PC. In this way, a digital card can be exchanged and a competitive game can be played between portable terminals located over a long distance. In addition, digital card registration is not limited to digital card registration companies,
The user may also go. In this case, the user can use the mobile terminal 11 or the mobile terminal 12 to register the digital card created by the user.

Next, a second embodiment according to the present invention will be described. In the first embodiment, the example in which the purchased digital card is stored inside the portable terminal has been described. In the present embodiment, the case where the purchased digital card is stored in the digital card database 30 will be described. I do.

Here, the digital card management server 20
Incorporates a digital card exchange program for exchanging digital cards among a plurality of users. The digital card management server 20 stores the digital card stored in the digital card database 30 in a storage area for each user in response to a user request from the mobile terminal 11 or the mobile terminal 12 based on the digital card exchange program. A digital card is exchanged among a plurality of users by storing and moving the digital card between storage areas. If the moved digital card is subject to copyright protection, data relating to the digital data is stored in a digital card database. 3
Delete from 0. The digital card management server 2
0 also incorporates a competitive game program for realizing a competitive game between a plurality of users using a digital card.

A user who wishes to purchase a digital card secures a storage area in the digital card database 30 for storing information on the purchased digital card and the like. Then, the user purchases the digital card by the same purchase operation as in the first embodiment. The digital card management server 20 stores the digital card purchased by the user in the user's storage area secured in advance. Further, the digital card management server 20 may store an identification number assigned for copyright management in a storage area instead of the digital card. The digital card database 30
In the case where the storage area of the user is not secured in advance, the digital card management server 20 may secure the storage area of the user and store the purchased digital card.

When the user wants to view his or her digital card, a browsing request is transmitted from the portable terminal 11 or 12 to the digital card management server 20. The digital card management server 20 reads the digital card from the storage area of the user and downloads the digital card to the portable terminal 11 or 12 in response to the request.

Next, the operation for exchanging the digital card possessed by each user will be described. FIG. 9 is a flowchart for explaining a digital card exchange operation. Here, a case where a digital card is exchanged between the user of the portable terminal 11 and the user of the portable terminal 12 will be described.

The digital card management server 20 provides an exchange home page for exchanging digital cards on the Internet 100. The user who wishes to exchange the card accesses the exchange homepage using the portable terminal 11 or the portable terminal 12 (step S61). Then, the mobile terminal 11 or the mobile terminal 12
Displays an exchange condition input screen as shown in FIG.

On the exchange condition input screen, the user
The user enters the exchange conditions including the user name, the name of the card (unnecessary card), and the name of the card desired (exchanged card) (step S62). Then, the digital card management server 20 stores the exchange condition input by each user (step S63).

The digital card management server 20 compares the exchange conditions registered by each user (step S6).
4). That is, the exchange condition presented by the user of the portable terminal 11 and the exchange condition presented by the user of the portable terminal 12 are compared. Then, it is determined whether or not the exchange conditions presented by both users match (step S65). For example, it is determined whether the digital card held by the user of the portable terminal 11 and the digital card desired to be exchanged match the digital card desired by the user of the portable terminal 12 and the digital card possessed by the user. Then, when the exchange conditions match, the exchange operation is performed, and when the exchange conditions do not match, the exchange operation ends. If the exchange conditions match, the digital card management server 20 deletes the exchange conditions.

The digital card management server 20 exchanges digital cards by moving data between storage areas corresponding to respective users in the digital card database 30 (step S6).
6). That is, the digital card of the user of the mobile terminal 11 is copied to a storage area corresponding to the user of the mobile terminal 12, and the digital card of the user of the mobile terminal 12 is copied to a storage area corresponding to the user of the mobile terminal 11.

The digital card management server 20 determines whether or not the copy source digital card is subject to copyright protection (step S67). If the digital card is subject to copyright protection, the digital card management server 20 deletes data relating to the digital card from the copy source storage area in the digital card database 30 (step S68). For example, when a digital card owned by the user of the mobile terminal 11 is subject to copyright protection, data related to the digital card is deleted from a storage area corresponding to the user of the mobile terminal 11. If the copied digital card is not subject to copyright protection, the subsequent processing ends. Here, the case where the information about the digital card is deleted from the storage area of the copy source in the case of the copyright protection is described as an example (steps S67 and S68).
Information about the digital card may be deleted from the storage area of the copy source regardless of whether or not the data is copyright-protected.

Further, even when a digital card is exchanged among a plurality of users, it can be executed in the same procedure as described above. The portable terminal 11 and the portable terminal 12 stored in the digital card database 30 are stored.
The user's digital card may be transferred to another user on the Internet 100 using an auction or the like.

Similarly, the user of the mobile terminal 12 arbitrarily selects a digital card from the digital cards displayed on the mobile terminal 12. Then, the selection information is transmitted to the portable terminal 11 via the digital card management server 20, and the portable terminal 11 displays the digital card selected on the portable terminal 12 side.

The user of the portable terminal 11 selects a special technique to attack the digital card selected by the user of the portable terminal 12. The digital card management server 20 reduces the points used for the special technique from the points of the digital card of the user of the portable terminal 11. For example, when a kick is used as a deadly technique, points corresponding to the kick are reduced. The digital card management server 20 sends an attack notification from the mobile terminal 11 to the mobile terminal 12. That is, the portable terminal 11 is notified of information about which special technique was used. The user of the mobile terminal 12 can respond to an attack from the mobile terminal 11 side. That is, it is possible to guard or use a special technique.

The digital card management server 20 reduces points used for guards and special moves from the digital card of the user of the portable terminal 12. If the mobile terminal 12 does not respond to an attack from the mobile terminal 11 (does nothing), the digital card of the user of the mobile terminal 12 is Damaged, digital card management server 20
Reduces points corresponding to the amount of damage from the digital card of the user of the portable terminal 12.

The digital card management server 20 determines the match result based on the points of the digital cards on the portable terminal 11 and the portable terminal 12. For example, if the point of either digital card becomes 0, that digital card is defeated. Then, the digital card management server 20 sets the portable terminal 1 in accordance with the match result.
The points of the digital card on the 1 side and the mobile terminal 12 side are increased or decreased (step S74). For example, predetermined points are added to a winning digital card. Further, the points which the other party originally has may be given to the processed digital card.

In the above description, the case where the battle game is played one-on-one has been described as an example. However, the battle game may be played one-to-many or a plurality-many. At this time, by adding a group attribute to the digital card, a dependency relationship between the digital cards can be established, and one camp (group) can be established. For example, a digital card in which points have accumulated more than a specified value has a parent status, and a plurality of digital cards can be used as subordinates. Then, a battle is performed between the parents, and the points of the digital card for the child can be increased or decreased according to the battle result of the parents. In addition, a fighting game can be played between camps. Furthermore, although the competitive game has been exemplified as a game, the present invention can be applied to other games as long as the game uses a digital card.

In the second embodiment, the digital card management server 20 manages a competitive game.
A game server may be separately installed.

In the first and second embodiments,
Although the case where the trading card is digitized has been illustrated, the present invention may be applied to a greeting card, a business card, and the like. Further, by replacing a trading card or the like with a digital card, not only point information and image information but also audio information can be added to the card. Therefore, a card having a higher function than the conventional card can be realized, and the entertainment value of the card can be improved. Further, the user can transfer his / her digital card to another user using an Internet auction or the like.

According to the present invention, by converting an exchangeable card such as a trading card into a digital card, the card provider can sell the card via the Internet. The purchased digital card can be stored as data in a portable terminal or a digital card management server on the Internet. Accordingly, the management of the digital card is facilitated, so that the loss of the digital card can be prevented. When the digital card is managed by the digital management server, the digital card can be prevented from being stolen. Further, when the digital card is stored in the portable terminal, the digital card is stored in the card storage unit provided with the copyright protection function, so that illegal copying of the digital card between the terminals can be prevented.

Further, by transmitting and receiving digital cards between portable terminals and in the digital card management server, digital cards can be exchanged between users, and the distribution of digital cards can be promoted.
At this time, if the transmitted / received digital card is subject to copyright protection, the source portable terminal or digital card management server performs processing for deleting data relating to the source digital card. Of the digital card can be prevented.
