The user sees the message of the registered information displayed on the screen and inserts the memory card 11 into the user terminal 1.
0 (step ST110), and by clicking the “Receive” button on the screen of FIG. 3 with a mouse,
The registration station terminal 20 is notified via the network 100 that the memory card 11 is set in the user terminal 10 (the memory card 11 is ready) (step ST111).

Upon receiving the notification that the memory card 11 has been set in the user terminal 10, the registration station terminal 20 transmits the user ID and the encryption key to the user terminal 10 via the network 100 (step ST112). Upon receiving the user ID and the encryption key, the user terminal 10 stores the user ID in the memory card 11 set in the user terminal 10.
D and the encryption key are stored (step ST113).

(2) Next, the operation of the purchase of digital data and the settlement processing of the purchase price will be described. FIG.
5 is a flowchart for explaining operations of digital data purchase and purchase price settlement processing in the digital data sales method of the present invention. The orderer (user)
The sales company terminal 30 accesses a homepage established on the network 100 via the user terminal 10 (step ST201). In response to this, the sales company terminal 30 transmits the product data information to the user terminal 10 via the network 100 (step ST202).

The user terminal 10 displays the product data information as shown in FIG. 4 on the screen (step ST203).
The orderer sees the product data information displayed on the screen of the user terminal 10, determines the product data to be purchased, and inputs on the screen a purchase purport (digital data to be purchased) (step ST204). In the example shown in FIG. 4, the input of the digital data to be purchased is performed by the orderer clicking the purchase check mark of the digital data to be purchased with the mouse.

The purchase data information input by the orderer is temporarily stored in the user terminal 10, and the orderer can confirm the purchase data information shown in FIG.
Is clicked on with a mouse, the purchase data information and the user ID of the orderer are transmitted to sales company terminal 30 via network 100 (step ST205).

Upon receiving the purchase data information and the user ID of the orderer from the user terminal 10, the sales company terminal 30
Recognizes the digital data purchased by the orderer from the purchase data information, and uses the digital data as the user ID of the orderer.
At the same time, it transmits to registration station terminal 20 via network 100 (step ST206).

Upon receiving the user ID and the digital data from the sales company terminal 30, the registration station terminal 20
The orderer is authenticated by D (step ST207), and the digital data is encrypted so that it can be decrypted only by the encryption key of the orderer (step ST208). Registration station terminal 20 transmits the encrypted digital data to sales company terminal 30 via network 100 (step ST209).

Upon receiving the encrypted digital data, sales company terminal 30 transmits the encrypted digital data to user terminal 10 via network 100 (step ST210).

User terminal 10 receives the encrypted digital data transmitted from sales company terminal 30, and stores the digital data (step ST21).
1). As described above, when using the purchased digital data, the user must always decrypt (decrypt) the encrypted digital data using the encryption key stored in the memory card 11. As a result, unauthorized use of digital data is prevented.

The sales company terminal 30 is connected to the network 100
, The charge information of the orderer is transmitted to the registration station terminal 20 (step S212). The registrar performs the settlement processing of the purchase price for digital data based on the charging information received by the registrar terminal 20 (step ST213).

The registration station terminal 20 performs the digital data encryption processing and the purchase payment settlement processing for a plurality of sales companies, not one sales company.

As described above, according to this embodiment,
Since the registration station terminal 20 performs digital data encryption processing in place of the sales company (sales company terminal 30), the sales company does not need to have an encryption system for encrypting digital data. The burden on the digital data encryption system can be reduced.
As a result, it is possible to streamline digital data sales operations of each sales company.

Further, the registration station terminal 20 registers a user (orderer) and issues a user ID and an encryption key to the user. Digital data purchased from a different sales company can be decrypted and used only by the encryption key of the terminal 20), and management of the encryption key by the user can be simplified.

Further, since the registration station terminal 20 performs the settlement processing of the purchase price in place of the sales company (sales company terminal 30), the burden on the sales company and the user involved in the settlement processing of the purchase price of the digital data. Can be reduced. As a result, the sales of digital data by each sales company can be made more efficient.
