INFORMATION PROCESSING TERMINAL AND CONTENT WRITING SYSTEM |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a technology for effectively preventing unauthorized copying of content data by making it difficult to observe storage processing of content data. <P>SOLUTION: A downloading command of content data 92 is transmitted to a server 2 from an information processing terminal 1. A server 2 transfers command data 91 to a command encrypting device 3. The command encrypting device 3 encrypts the command data 91 in an encrypting circuit 31. The server 2 transmits the content data 92 and encrypted command data 91 to the information processing terminal 1. A control part 11 of the information processing terminal 1 transfers the content data 92 and encrypted command data 91 to a memory controller 132. The memory controller 132 decodes the command data 91 by a decoding circuit 1321 and stores the content data 92 in an memory array 131. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
