<P>PROBLEM TO BE SOLVED: To solve the problem with mobile wireless terminals capable of sending and receiving various data wherein the terminals, which recently gained widespread use and enable advertisement data based on their functions to be provided to terminals in transit, could get mobile communication terminals into trouble since the mobile communication terminals have no means to ascertain the truth of the information received. <P>SOLUTION: When advertisement data are created, an ID storage to be stored in the data in advance is provided to store the terminal ID of the terminal body thereof which created the data and the terminal ID of a partner terminal transferred from the terminal. A computer program built into the terminal authenticates the terminal ID of the terminal and the terminal ID in the ID storage and permits transfers from the terminal only if transfer requirements are met. This protects the copyright of the creator and inhibits data alteration and abuse, thereby enhancing the credibility of the advertisement data. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
