2. Description of the Related Art Conventionally, the following two methods have been considered to realize pay broadcasting on the Internet. (1) Credit card method A user (user) is registered by transmitting a credit card number or the like from a personal computer (PC) to a distribution server, and a user I who uniquely identifies the user is registered.
Have D and password (PIN) issued. At the time of viewing content or purchasing a product, a pay content is viewed by inputting an ID and a password from a PC. Billing (collection of fees) is performed from a credit card. (2) Cellular phone system Identity verification is performed by using a function that can securely transmit a telephone number that cannot be rewritten by an unauthorized operation of a user or an individual identification number of a cellular phone to a base station, and pay content is stored on the cellular phone. To view and pay the viewing fee from the telephone fee. This is a typical example of i-mode of NTT DOCOMO.

[0003]

The above method has the following problems. (1) Credit card method-A credit card number must be entered for each distribution server for user registration, and the credit card number, ID, and password must be registered by a third party on the communication path between the receiving device and the distribution server. There has been a problem that eavesdropping or being stolen by the distribution server administrator purchases contents and the like by impersonating another person. -There is a possibility that the user forgets the ID and password. (2) Mobile phone system-The processing capacity of mobile phones and the communication capacity due to mobile communication are limited, and it has been difficult to distribute moving image content such as high-quality movies.

[0004] In either case (1) or (2), music, music, or the like is not limited to pay broadcasts on the Internet, that is, sales (purchase) of services.
Purchase of images, programs, etc., daily necessities,
When purchasing clothes and other general merchandise via the Internet (mail-order sales), the user must also enter a credit card number for each sales server to perform user registration, eavesdropping by a third party, and managing the sales server. There were similar problems such as misuse by the elderly.

[0005]

According to the present invention, a receiving request used by a user sends a purchase request, that is, a request for purchasing a broadcast service, or a decision to purchase content or a tangible product to a communication network with respect to a selling device. Through this, the vending apparatus creates an identification information ID for uniquely identifying the purchase request (purchase decision), stores the ID and a receiving apparatus ID for uniquely identifying the receiving apparatus as a set, and stores the ID. Information ID
Is returned to the receiving device. Upon receiving the identification information ID, the receiving device notifies the user of the fact. For example, the ID is displayed on the screen and notified. The user connects the mobile terminal to the charging device, and transmits the identification information ID and the mobile terminal ID for uniquely identifying the mobile terminal to the charging device from the mobile terminal. The mobile terminal ID cannot be changed without permission, unlike the telephone number or device number of a mobile phone.

[0006] The billing device stores the received identification information ID and the portable terminal ID as a set, and transmits the identification information ID to the sales device. When the vending device receives the identification information ID, and sells the content distribution service, the vending device is set in a state where the device can receive the service to the receiving device corresponding to the identification information ID,
Upon receipt of the service purchase completion notification from the receiving device, the charging device generates billing information for the service sales fee of the receiving device, transmits the billing information to the billing device together with its identification information ID, and the billing device receives the received identification. Based on the information ID and the charge information, the charge information is added to the charge for the portable terminal ID corresponding to the stored identification information ID.

On the other hand, when the vending apparatus receives the identification information ID, and the vending apparatus sells the product, the charging information corresponding to the price of the product determined to be purchased first is created from the identification information ID. And the accounting information is transmitted to the identification information I.
D and transmitted to the billing device. The processing in the charging device is the same as in the case of selling a service. If the selling device sells the content as a product, the billing information is transmitted to the billing device, and the purchased content is downloaded to the receiving device of the receiving device ID corresponding to the identification information ID. If the product determined to be purchased is a tangible product, a process for notifying the receiving device of the completion of the product transaction process and performing product delivery is performed.

In the first embodiment, the sales apparatus 30 is a distribution server that broadcasts and sells contents. Hereinafter, a procedure for purchasing a content broadcasting service will be described.
FIG. 2 shows the overall flow. The user 11 operates the operation unit 110 of the receiving device 10.
Is operated to input the connection to the distribution server 30 and the service purchase request, the receiving device 10 connects the receiving device 10 to the distribution server 30 and transmits the service purchase request (1). Upon receiving this, the distribution server 30 receives the reception device ID.
(2), and transmits the receiving device ID and the billing server address to the receiving device 10 (3). This receiver ID
Is information that can uniquely identify the receiving device 10, and for example, numbers may be assigned in the order of service purchase requests. The charging server address is, for example, a URL (Uniform Resource Locator) of the charging server (charging device) 40. The receiving device 10 displays the received receiving device ID and charging server address on the screen 111 and notifies the user 11 (4). Further, the distribution server 30 stores a set of the receiving device ID of the receiving device 10 and the address of the receiving device 10, for example, an IP address as an ID.
It is stored in the storage unit 310 (5).

[0010] The distribution server 30 encrypts stream contents such as video and music using a common key encryption method such as DES (6). However, it is assumed that the common key is changed every predetermined period such as 15 minutes, or each time a condition such as a change in content is satisfied (7). Let this common key be k (t). The encrypted content is referred to as encrypted content C (t). Encrypted content C
It is assumed that (t) is distributed to each receiving device using multicast or the like (8). In this example, the user (user) 11 uses the mobile terminal 20 having an Internet connection function, operates the operation unit 21 and inputs the billing server address displayed on the receiving device 10 to connect the mobile terminal 20. (9). A WWW page (Web screen) sent from the charging server 40 is displayed on the display screen 22 of the mobile terminal 20 (10), and this screen has a form (area) for inputting a receiving device ID, and the user 11 Operates the operation unit 21 of the portable terminal 20 and inputs the receiving device ID (11).

When receiving the receiving device ID from the charging server 40, the distribution server 30 refers to the ID storage unit 310 and transmits the common key k (t) to the receiving device 10 having the corresponding IP address (receiving device address). The data is transmitted as a cast (15), and a valid flag is set for the receiver ID. The transmission time at that time is stored for the corresponding receiving device ID. However, the communication path at this time is desirably a secure communication path such as SSL. Distribution server 30
Until the viewing end information is received from the user via the receiving device 10, every time the common key k (t) is changed, the flag in the ID storage unit 310 is set to all of the receiving devices with valid receiving device IDs. The transmission of the new common key k (t) is continued (16). The delivery timing of the common key k (t) is assumed to be transmitted before the encryption key of the encrypted content C (t) is switched. The receiving device 10 uses the common key k
When (t) is received, the encrypted content C (t) multicast-distributed using the common key k (t)
Can be decrypted, and the user can view the content. That is, in this example, the distribution server 30
By delivering (t) to the receiving device 10, the receiving device 10 is set to a state in which the content can be viewed.

When ending the viewing of the content, the user 11 transmits viewing end information from the receiving device 10 to the distribution server 30 (17). Upon receiving the viewing end information from the receiving device 10, the distribution server 30 receives the IP
The transmission of the common key k (t) to the receiving device 10 of the address is stopped. This makes it impossible for the receiver 10 to view the content within the predetermined period. The distribution server 30 creates billing information for the user 11 from the transmission time of the first common key k (t) to the receiving device 10 and the reception time of the viewing end information (18), and the billing server via the secure communication path. 40 for receiving device I
A set of D and its billing information is transmitted (19). Also, ID
