A server stores original data without a water-mark. When a user at a terminal apparatus connected with the server requests the server to display the original data on a display of the terminal apparatus, the server transforms the original data into an image data. Then the server adds a water-mark to the image data and transmits the image data with the water-mark to the terminal apparatus.

Server, a terminal apparatus and an image management method

In a communication method for enabling communication between a card and a management server that manages the card and for writing information transmitted from the management server to the card, a server state flag and a card state flag are created to indicate the processing state of the management server and the processing state of the card, respectively. The server state flag and the card state flag are occasionally updated during communication between the card and the management server. On the basis of the card state flag, it is determined whether or not the writing by the management server to the card is completed normally. When the writing is not completed normally, the card is rewritten the next time communication is established between the card and the management server, the rewriting being defined in accordance with the card state flag and the server state flag.
