Abstract

An information management system, including: a first information terminal including an input device a storage medium, and a transmitter-receiver; and a server including a storage medium and a transmitter-receiver; wherein, during a synchronization of data within the respective storage mediums of the information terminal and the server, a portion of information held by the storage medium in the first information terminal is deleted upon the setting of a deletion flag corresponding to the information, matching the information to be deleted from the storage medium of the first information terminal, and held by the storage medium in the server.

Claims

1. An information management system, comprising:

(a) an information terminal including an input device from which information is inputted, a storage device in which the information is stored, and transmit-receive device;

(b) a server including a storage device into which the information is stored and a transmit-receive device, whereby doing information-synchronization with the information terminal; and

c) wherein, the information held by the storage device in the information terminal is deleted upon set of a deletion flag as to the information held by the storage device in the server.

2. The information management system according to claim 1, wherein the information held by the storage device in the server is not deleted irrespective of the deletion flag.

3. The information management system according to any one of claims 1-2, wherein there exists a plurality of the information terminals, and further wherein the information held by the storage device in one of the information terminals is deleted upon deletion of the information held by the storage device in other of the information terminals.

4. An information management system, comprising:

(a) an information terminal including an input device from which information is inputted and a transmit-receive device;

(b) a server including a storage device into which the information is stored and a transmit-receive device, whereby communicating with the information terminal; and

(c) wherein, a deletion flag as to the information held by the storage device in the server is set when a delete command as to the information held by the storage device in the information terminal is entered into the information terminal.

5. An information management system server, comprising:

(a) a transmit-receive device that communicates with an information terminal;

(b) a storage device into which information held by the information terminal is stored; and

(c) wherein, information synchronization with the information terminal is done, and thereby a deletion flag as to the information stored in the storage device is set upon deletion of the information held by the storage device in the information terminal.

6. The information management system according to claim 5, wherein the information held by the storage device is not deleted irrespective of the deletion flag.

7. An information management system terminal, comprising:

(a) a transmit-receive device that communicates with a server;

(b) a storage device into which information held by the server is stored; and

(c) wherein, information synchronization with the server is done, and thereby the information stored in the storage device is deleted upon set of a deletion flag as to the information held by the server.
