Abstract

A system for providing non-standard characters over a network is provided. The system includes: (a) a non-standard character server coupled to the network, (b) a character database coupled to the server, and (c) one or more client terminals coupled to the network. A user of each client terminal may create a non-standard character and send a non-standard character index issuance request for the created non-standard character to the non-standard character server. The non-standard character server receives the non-standard character index issuance request including an image of the non-standard character created by the client terminal, automatically assigns an index number to the received image of the non-standard character, stores the received image of the non-standard character and the index number assigned thereto in the character database, and sends the index number assigned to the received image of the non-standard character to all of the client terminals on the network.

Claims

1. A system for providing non-standard characters over a network comprising:

(a) a non-standard character server coupled to the network;

(b) a character database coupled to the server; and

(c) one or more client terminals coupled to the network, each client terminal being configured to create a non-standard character and send a non-standard character index issuance request for the created non-standard character over the network to the non-standard character server;

wherein the non-standard character server comprises;

(i) a client management module that is configured to receive a non-standard character index issuance request including an image of a non-standard character created by a client terminal, and to automatically assign an index number to the received image of a non-standard character;

(ii) a character database management module that is configured to store the received image of a non-standard character and the index number assigned thereto in the character database; and

(iii) a non-standard character assignment module that is configured to send the index number assigned to the received image of a non-standard character to each of the one or more client terminals.

2. The system of claim 1, wherein the client management module is further configured to send the image of a non-standard character received from the client terminal to a computer of a character designer, and to receive non-standard character data created by the character designer therefrom.

3. The system of claim 1, wherein the non-standard character index issuance request comprises a standard character code corresponding to the non-standard character created by the client terminal, the database management module is further configured to search for a set of one or more non-standard characters corresponding to the received standard character code in the character database, and the client management module is further configured to calculate moment values for each of the set of one or more non-standard characters corresponding to the received standard character code for training a neural network to identify an index number for each of the set of one or more non-standard characters.

4. The system of claim 3, wherein the client management module is configured to calculate moment values for the image of the non-standard character created by the client terminal, and to further train the neural network to identify a unique index number for the image of the non-standard character created by the client terminal.

5. The system of claim 3, wherein the moment values for each of the set of one or more non-standard characters consist of first and second moment values.

6. The system of claim 1, wherein the database management module is further configured to search non-standard characters in the character database based on an index number.

7. A method for providing non-standard characters over a network, the network comprising a non-standard character server, a character database, and one or more client terminals, wherein the method provides non-standard characters from the non-standard character server to each of the one or more client terminals, the method comprising the steps of:

(a) one of the one or more client terminals creating and sending an image of a non-standard character and a non-standard character index issuance request to the server;

(b) the server receiving the non-standard character index issuance request and the image of the non-standard character from the client terminal;

(c) the server determining whether the non-standard character received from the client terminal is already registered in the character database;

(d) if it is determined that the non-standard character is not registered in the character database in step (c) above, the server assigning a new index number to the received non-standard character and storing the image of the received non-standard character with its newly assigned index number in the character database; and

(e) the server sending the newly assigned index number to each of the one or more client terminals.

8. The method of claim 7, wherein step (c) further comprises the sub-steps of:

(i) verifying whether the non-standard character index issuance request is valid;

(ii) calculating first and second moment values for the image of the non-standard character received from the client terminal;

(iii) determining an index number for the image of the non-standard character received from the client terminal based on the first and second moment values calculated in sub-step (ii) above; and

(iv) searching for any non-standard character registered in the character database based on the index number determined in sub-step (iii) above.

9. The method of claim 8, wherein sub-step (c)(i) comprises verifying whether the non-standard character index issuance request includes a standard character code corresponding to the image of the non-standard character.

10. The method of claim 8, wherein sub-step (c)(iii) comprises determining an index number by inputting the first and second moment values into a neural network.

11. The method of claim 8, wherein step (d) comprises the use of a neural network, and further comprises training the neural network so that input of the first and second moment values for the image of the non-standard character as calculated in sub-step (c)(ii) will produce a unique index number to be assigned to the received non-standard character.

12. The method of claim 7, wherein step (d) further comprises storing in the character database all non-standard characters corresponding to one standard character code in association with each other.

13. A computer-readable tangible medium comprising computer executable instructions which, when loaded onto a non-standard character server coupled with a character database and one or more client terminals via a network, cause the non-standard character server to perform the steps of:

(a) receiving a non-standard character index issuance request and an image of a non-standard character created by one of the one or more client terminals from that client terminal;

(b) determining whether the non-standard character received from the client terminal is registered in the character database;

(c) if it is determined that the non-standard character is not registered in the character database in step (b) above, assigning a new index number to the received non-standard character and storing the image of the received non-standard character with its newly assigned index number in the character database; and

(d) sending the newly assigned index number to each of the one or more client terminals.

14. The computer-readable tangible medium of claim 13, wherein the computer executable instructions cause the non-standard character server to perform the further sub-steps in step (b) of:

(i) verifying whether the non-standard character index issuance request is valid;

(ii) calculating first and second moment values for the image of the non-standard character received from the client terminal;

(iii) determining an index number for the image of the non-standard character received from the client terminal based on the first and second moment values calculated in sub-step (ii) above; and

(iv) searching for any non-standard character registered in the character database based on the index number determined in sub-step (iii) above.

15. The computer-readable tangible medium of claim 14, wherein sub-step (b)(i) comprises verifying whether the non-standard character index issuance request includes a standard character code corresponding to the image of the non-standard character.

16. The computer-readable tangible medium of claim 14, wherein sub-step (b)(iii) comprises determining an index number by inputting the first and second moment values into a neural network.

17. The computer-readable tangible medium of claim 14, wherein step (c) comprises the use of a neural network, and further comprises training the neural network so that input of the first and second moment values for the image of the non-standard character as calculated in sub-step (b)(ii) will produce a unique index number to be assigned to the received non-standard character.

18. The computer-readable tangible medium of claim 13, wherein step (c) further comprises storing in the character database all non-standard characters corresponding to one standard character code in association with each other.
