The operation of copying the encrypted content in the partail ROM-type memory card to the ram-type memory card 112 is described in the above. As described above, the memory card 112 provided with RAM can autonomously train the server 30 to receive the encrypted content data {Data} Kc, the content decoding key Kc, and the authorized information distribution communication to perform music reproduction. However, when the user 2 receives content data containing a considerable amount of information directly from the server 30, it takes a long time to receive the message. At this time, if the content data can be directly copied by the server 1 having a memory card that has stored the encrypted data, the convenience of the user will be improved. 0 ------------- ---- Install ------------ (Please read the precautions on the back before copying each block on this page) The Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the original to protect the rights of copyright holders. The starting point is that the structure of the system does not allow free copying of content materials. Fig. 11 is a conceptual diagram for explaining the structure of the data distribution communication system of the second embodiment. As shown in Figure 11, copying only the encrypted data is called "copying". Since the copy does not include a copy of the authorized data, User 2 cannot reproduce the content data. Therefore, the user 2 can reproduce the content data by re-performing the distribution communication for separately transmitting the authorization data. With the above structure, the user can flexibly utilize the encrypted content data stored in the PartlalR0M type memory card 11. In addition, when the mobile phones 100 and 102 are of PHS (Pers 嶋 i ㈣ type), since the so-called wireless transceiver can be used, the Chinese national standard (CNS) A4 regulations apply to this paper standard ^ Γ10 x & Gongchu 42 312383 Booking line 497348 Α7 B7 V. Invention description (43 This function can be used to perform the copying of information between the user 丨 and user 2. In addition, when the mobile phone is a device that can be equipped with a few memory cards In the case of a mobile phone, a partial ROM type memory card 110 and a RAM type memory card 112 can be installed in the mobile phone at the same time to perform information copying. Figure 12 shows that the corresponding partiai rom type memory card is already in section Π. The illustration of the data and key used in the data distribution communication system illustrated in the figure is in contrast to the second figure. Unlike the partial ROM type memory card 11 shown in the second figure, the key K (i) It is not inherent in the type of content data, but is a kind of common recording inherent in each memory card. As for the other aspects, since it is the same as that in FIG. 2, the description will not be repeated here. [Configuration of RAM Type Memory Card 112] Section 13 The picture shows The schematic block diagram illustrating the structure of the memory card 112 shown in Fig. Π is contrasted with Fig. 5 which shows the structure of the memory card 110.

In addition, the memory card 14 15 described in the following description is defined as a flash memory, which is a representative nonvolatile memory that can be read and written at any time. [Copy operation] Fig. 14 is a flowchart for explaining the encrypted data copy processing (copy dialog) from the partial ROM type memory card 11 of the user 1 to the RAM type memory card of the user 2. First, when the user 1 of the mobile phone 100 executes the content data copy request (step S300), the encrypted content data {Data} Kc and the additional information Data-inf are output from the memory 1415 of the partail ROM-type memory card 110 (step S300). 302).
