Abstract

A modified data synchronization system having data security and proxy capabilities has a delivery server, a PC, and at least one mobile phone. The PC sends out the exchange data through the Internet to a remote location where the delivery server is installed, and then one mobile phone compliant with SyncML protocols dials in to conduct data synchronization with the delivery server through wireless means, through which the existing data discrepancy between the mobile phone and the PC can be eliminated. The PC does not need to install a dedicated SyncML server, and data security can be ensured in the synchronization process, as data transfer between the PC and the delivery server through secured protocol over the Internet, and that between the mobile phone and the delivery server is through a dedicated channel.

Claims

1. A modified data synchronization system having data security and proxy capabilities, comprising a delivery server (100), a PC (200) and at least one mobile phone (300), wherein

the delivery server (100), which is implemented by a proxy server compliant with SyncML protocols, is composed of a communication manager (101), a synchronization manager (102), and a dynamic data storage (103);

and

the delivery server (100) is embedded with a data read/write instruction set to allow the communication manager (101) to receive the exchange data from the PC (200) through the Internet, and has the dynamic data storage (103) for temporarily saving the exchange data to allow the synchronization manager (102) to be connected to the at least one mobile phone (300) through the switching system (400) to conduct data synchronization compliant with SyncML protocols;

the PC (200) is embedded with a network user interface (201) and a remote-end net driver (202), wherein the network user interface (201) is to set up the interface to be connected to the delivery server (100) for uploading and downloading of requested data for use in data synchronization; and

the at least one mobile phone (300) is built in with a mobile user interface (301) that can support the SyncML protocols, such that the mobile user of the at least one mobile phone (300) can be connected by a WAP gateway provided by the service provider to the synchronization manager (102) for the requested data synchronization.

2. The modified data synchronization system as claimed in claim 1, wherein the data transfer between the PC (200) and the delivery server (100) is routed through the Internet with secured data transmission.

3. The modified data synchronization system as claimed in claim 1, wherein the data transfer between the switching system (400) and the delivery server (100) is conducted through a dedicated channel of the service provider without routing through the Internet.

4. The modified data synchronization system as claimed in claim 1, wherein the existing copy of the exchanged data in the dynamic data storage (103) of the delivery server (100) is to be deleted automatically after the data synchronization is completed to ensure data confidentiality.

5. The modified data synchronization system as claimed in claim 1, wherein after receiving data copy from the PC (200), the delivery server (100) sends a short message to the at least one mobile phone (300) notifying the mobile phone to prepare for data synchronization.
