Message service method for mobile communication terminal using position information
First Claim
Patent Images
1. A method for providing a message service for use in a mobile communication terminal, comprising the steps of:
- establishing a security mode using reading position information as an encryption key and a locking key and for determining a readable position at which a message to be transmitted can be read such that the message is encrypted and locked;
generating a security message;
designating a destination mobile communication terminal; and
transmitting the security message to the mobile communication terminal wherein the security message, which is a message encrypted using the reading position information as an encryption key, is locked using the reading position information as a locking key, and the release of the security mode is performed using the current position information as a release key to release the locking of the security message, and is performed by decoding the security message using the current position information as a decoding key.

10. A method for providing a message service to a destination mobile communication terminal over a mobile communication network, comprising the steps of:
-
receiving a security message in which an ESN (Electronic Serial Number) encryption request is established wherein the security message, which is a message encrypted using the reading position information as an encryption key, such that the message to be transmitted is encrypted and is locked using the reading position information as a locking key, and the release of the security mode is performed using the current position information as a release key to release the locking of the security message, and is performed by decoding the security message using the current position information as a decoding key; encrypting the security message using an ESN of the destination mobile terminal associated with the security message as an encryption key; and transmitting the ESN-encrypted security message to the destination mobile terminal.

11. A method for providing a message service for use in a mobile communication terminal, comprising the steps of:
-
receiving a security message in which a security locking-mode is established from reading position information indicating a readable position; releasing the security locking-mode of the security message using current position information of the mobile communication terminal when a user requests to read the security message; and displaying contents of the message in which the security locking-mode is released and the release of the security mode is performed using the current position information as a release key to release the locking of the security message, and is performed by decoding the security message using the current position information as a decoding key, wherein the security message, which is a message encrypted using the reading position information as an encryption key, is locked using the reading position information as a locking key, and the release of the security mode is performed using the current position information as a release key to release the locking of the security message, and is performed by decoding the security message using the current position information as a decoding key. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A system for providing a message service, comprising:
-
a mobile terminal for establishing a security mode using reading position information for designating a readable position at which a message to be transmitted can be read, generating a security message, establishing an ESN (Electronic Serial Number) encryption request for requesting ESN encryption of the security message, and then transmitting the security message wherein the security mode establishment is performed by locking and encrypting the message to be transmitted by adapting and using the reading position information as the locking key and encryption key, and wherein the release of the security mode is performed by releasing the locking of the security message by adapting the reading position information as the release key and decoding the security message using the reading position information as a decoding key; a mobile communication network for receiving the security message in which the ESN encryption request is established, encrypting the security message, and transmitting the encrypted security message; and a destination mobile terminal for receiving the encrypted security message, decoding the encrypted security message using an ESN as a decoding key when a reading request for the security message is received from a user, releasing a security mode of the security message using current position information of the destination mobile terminal, and displaying message contents, wherein the encrypted security message is encrypted using an ESN of the destination MS associated with the security message as an encryption key. - View Dependent Claims (23)
