The point information is information indicating the cumulative amount of service points for each production company 3, and the user 1 can receive a viewing service such as a discount on admission fees for movie theaters, theaters, etc., and cashback, etc., with these service points. it can.

The CPU 12 is a central processing unit for centrally controlling the member IC card 10, and includes an I / O interface 11, a RAM 13, a ROM 14, and an EEPROM 1.
A memory or the like such as 5 is connected. CPU12 is I /
A command is received from the receiving terminal 20 via the O interface 11, and processing is performed using the work area of the RAM 13 based on the program stored in the ROM 14 or the EEPROM 15. The processing result is transmitted to the receiving terminal 20 as a response.

FIG. 5 is a flow chart showing an embodiment of the IC card and the software distribution device according to the present invention. Hereinafter, the processing of the receiving terminal 20 will be mainly described. In the receiving terminal 20, the user 1 inserts the member IC card 10,
The process is started by accessing the distribution server 30 (S100, S101).

In S102, the receiving terminal 20 reads the user ID and the stored identification information of the manufacturer application 50-1 or 50-2 from the member IC card 10 and sends it to the distribution server 30. Delivery server 3
0 refers to the received user ID in the member database and authenticates the member. When authenticated, a list of information in which the content of the browsing service is linked to the identification information of the browsable content 60 is transmitted to the receiving terminal 20.

In S103, the user 1 selects the content 60 to browse. The receiving terminal 20 displays the received list information on the display 25. User 1
Selects the content 60 desired to be browsed from among the displayed various contents 60, using the content of the content 60 and the content of the browsing service as a judgment material. The input selection information of the content 60 is transmitted to the distribution server 30. The distribution server 30 uses this selection information and S10.
The identification information of the manufacturer application 50 received in 2 is collated to determine whether the manufacturer application 50 of the manufacturer 3 providing the selected content 60 is stored in the member IC card 10.
If stored, the selected content 60 and its header information are encrypted with the manufacturer encryption key, and if not stored, encrypted with the distributor encryption key,
It transmits to the receiving terminal 20. The distribution server 30 divides the content 60 into several pieces, and transmits them in chapter units while timing with the receiving terminal 20.

In S104, the receiving terminal 20 receives the header information encrypted with the encryption key and reads the corresponding encryption key from the member IC card 10 to authenticate the content 60. The receiving terminal 20 receives the content 6
When 0 is encrypted by the manufacturer encryption key, the manufacturer encryption key is read from the member IC card 10, and when encrypted by the distributor encryption key, the distributor encryption key is 0. Read out.

In S106, the receiving terminal 20 receives the encrypted chapter. The receiving terminal 20 decrypts this chapter using the encryption key read in S104 (S107). The payment method for the member IC card 10 is
For the chapter received in S106, the browsing fee is calculated based on the charging algorithm of the corresponding manufacturer application 50 and collected from the electronic money 16 (S108). The point conversion means converts the browsing time into service points and rewrites the point information based on the point conversion algorithm stored in the manufacturer application 50 (S109). S10
8, the receiving terminal 20 displays the content of the chapter received in S106 on the display 25, and the user 1
Browses the content 60. When the user 1 interrupts the browsing in the middle of the content 60 (S111), the receiving terminal 20 connects the history information in which the browsing time is associated with the identification information of the browsed content 60 to the E of the member IC card 10.
Writing to the EPROM 15 (S113), and the process ends (S114).

The receiving terminal 20 repeats the same processing until the final chapter (from S106 to S112), and when the display of the final chapter is completed, the contents 6
The identification information of 0 is written in the EEPROM 15 as history information (S113), and the process is terminated (S114).

As described above, according to this embodiment, since the user 1 pays the fee in chapter units, it is possible to omit the unnecessary payment of the browsing fee and improve the convenience of the user 1. became. In addition, member IC card 1
Since 0 stores history information, even if the user 1 unavoidably interrupts browsing on the way, the content 60
The distribution company 2 can receive the distribution from the interruption point, and the distribution company 2 can utilize the history information such as providing the production company 3 with the browsing details based on the history information. .
Furthermore, since the user 1 can select and receive various browsing services provided by the production company 3, it is possible to further improve convenience. On the other hand, production company 3
Recommends browsing of the content 60 produced by itself by a unique browsing service such as a unique billing algorithm, and differentiates it from the content 60 of other producers 3, thereby enclosing the user 1. It has become possible. Furthermore, since the member IC card 10 pays the viewing fee with the electronic money 16 before displaying the content 60 on the display 25 (S108, S110, see FIG. 5), the distributor 2 and the manufacturer 3 Enables to easily settle the browsing fee and at the same time prevent the collection of the browsing fee.

(Modifications) The present invention is not limited to the above-described embodiments, but various modifications and changes can be made, which are also within the scope of the present invention. For example, in this embodiment, the member IC card 10 is a contact type IC card, but it may be a non-contact type or a contact / non-contact type IC card.

The member IC card 10 stores the first and second production company applications 50-1 and 50-2, but may store three or more production company applications 50.

The receiving terminal 20 uses the encryption key of the member IC card 10 to decrypt the encrypted content 60. If the CPU 12 of the member IC card 10 has high-speed processing capability, the CPU 12 Is the content 60 as a decryption means according to the instruction of the application 50.
May be decrypted. When the capacity of the EEPROM 15 is large, the content 60 encrypted and transmitted by the distribution server 30 may be stored in a rewritable memory such as the EEPROM 15 and decrypted.

The manufacturer application 50 stores the charging algorithm unique to the manufacturer 3, but
The manufacturer application 50 may store two or more unique charging algorithms. Content 6
By including the information for selecting the charging algorithm in the heading information of 0, the browsing fee can be set more finely for each content 60. For example, for the new content 60, it is possible to set an expensive fee.

[0052]

As described above in detail, since the delivery fee is calculated based on the type and / or the portion of the software, it is possible to omit the useless payment of the fee and to differentiate the software so that the user can be differentiated. It has become possible to improve convenience. Further, similarly, the service points are calculated based on the type and / or the portion of the software, and the calculated service points are accumulated and stored, so that the software can be differentiated,
It has become possible to further improve user convenience.
Further, since the history information is stored, for example, when the user unavoidably interrupts the browsing of the software on the way, the history information can be utilized such as receiving the distribution from the interrupted place. Furthermore, since the cash information is stored and the delivery fee is settled, the convenience of the user is improved and the delivery fee can be collected without fail.
