FIG. 7 is a sequence diagram of advertisement distribution processing by the information system 1. The mobile phone 5 starts an application program stored in the IC chip 11 corresponding to the information service provided by the store terminal 5 (step S201), and requests settlement from the store terminal 7 (step S202). When the shop terminal 7 requests the mobile phone 5 for authentication (step S203), the authentication unit 61 of the mobile phone 5 uses an authentication code necessary for electronic money settlement such as an IC chip identification number stored in advance. Is transmitted to the store terminal 7 (step S204). Here, as an authentication code necessary for authentication, information input from a user to an input unit such as a button provided in the mobile phone 5 may be used.

  Then, mutual authentication processing is performed between the mobile phone 5 and the store terminal 7 (step S205), and when it is determined that authentication is possible, the store terminal 7 transmits a user information read request to the mobile phone 5. (Step S206). The cellular phone 5 requests the IC chip 11 provided therein to read out the user information (step S207), reads out the user information through the IC chip 11 (step S208), and reads out using the encryption key E. The user information is encrypted (step S209), and the encrypted user information is transmitted to the store terminal 7 (step S210). The shop terminal 7 transmits the received encrypted user information to the advertisement distribution server 3 (step S211). Here, since the user information is encrypted and the store terminal 7 does not have a decryption key corresponding to the encryption key E, the store terminal 7 cannot refer to what information is included in the user information. .

  The advertisement distribution server 3 decrypts the received encrypted user information using the decryption key D (step S212). The advertisement distribution unit 37 of the advertisement distribution server 3 selects an advertisement ID suitable for the user of the mobile phone 5 by comparing the decrypted user information with the advertisement selection rule stored in the advertisement selection rule storage unit 43. Then (Step S213), the advertisement selection unit 35 reads the advertisement information corresponding to the advertisement ID from the advertisement content storage unit 41 (Step S214).

  The advertisement distribution unit 37 of the advertisement distribution server 3 transmits the advertisement information selected and read by the advertisement selection unit 35 to the store terminal 7 (step S215), and the store terminal 7 transmits the received advertisement information to the mobile phone 5. (Step S216). The mobile phone 5 displays the received advertisement information on a display unit such as a screen provided in the mobile phone 5 (step S217). If the received advertisement information is, for example, a coupon that can be used at the next visit to the store, the IC chip 11 is displayed. (Step S218). Thereafter, when a settlement process is performed between the mobile phone 5 and the store terminal 7 (step S219), the mobile phone 5 finishes executing the application program corresponding to the information service, and is stored in the usage history information storage unit 65. The usage history information about the executed payment process is added to the usage history information and stored (step S220).

  By the above advertisement distribution processing, for example, when the user of the mobile phone 5 is “male”, “PC purchase” is used at the usage date “2008/2/15 14:00” in the usage history information storage unit 65 shown in FIG. ”Is used, the usage service ID is“ 000001 ”, and the advertisement selection rule storage unit 43 shown in FIG. 6 satisfies the condition of the attribute information“ male ”of the usage service ID“ 000001 ”, and the usage history Since the information is satisfied, the advertisement content with the advertisement ID “002” is selectively distributed, and “audio device advertisement” is transmitted and displayed on the mobile phone 5 as shown in FIG.

Next, a supplementary explanation will be given regarding the encryption of user information in the present embodiment. The encryption of user information includes a method using a PKI (Public Key Infrastructure) and a method using a common key.
In the method using PKI, the encryption key E stored in advance in the mobile phone 5 is used as the public key of the advertisement distributor. Further, the decryption key D stored in advance in the advertisement distribution server 3 is used as the secret key of the advertisement distribution company, and the user information encrypted by the encryption key E is decrypted by using the decryption key D.

  In the method using the common key, the common key C is stored in advance in the mobile phone 5 and the advertisement distribution server 3 as shown in FIG. The cellular phone 5 encrypts the hash value h generated based on the user ID with the common key C, and generates the encryption key E. The cellular phone 5 encrypts the user information using the generated encryption key E, and transmits the hash value h and the encrypted user information to the advertisement distribution server 3 in step S210 and step S211 of FIG. The advertisement distribution server 3 generates a decryption key D from the hash value using the common key C, decrypts the encrypted user information with the decryption key D, and obtains user information.

  As described above, according to the present embodiment, the user information stored in the IC chip 11 is encrypted, and the store terminal 7 reads and passes it to the advertisement distribution server 3 having a decryption function. User information such as the service list, attribute information, and usage history information of the user of the telephone 5 cannot be read out, and the confidentiality of information such as a store that provides other services or a service of the own store can be maintained. In addition, since the user identification information stored in the mobile phone 5 or the IC card is not sent to the advertisement distribution server 3, the advertisement distribution server 3 cannot specify the user of the mobile phone 5, so that the user's personal Information will be protected. Thus, advertisements suitable for the user are distributed to the user's mobile phone 5 while protecting the user's personal information, business confidential information of the store, and the like.
