PURPOSE: A method for synchronizing personal information between data communication equipments to use a multi-synchronizing tool is provided to synchronize the personal information stored in a web server and the data communication equipments by discriminating an actual synchronization target through comparison between key fields of synchronization target data and current data. CONSTITUTION: Data synchronization is requested by updating the personal information of a user and uploading the updated data to a synchronization server through the first data communication terminal(303). The uploaded data is analyzed and the synchronization target data is extracted/stored in a synchronization database(304). The actual synchronization target data is judged by mapping the key value of the data stored in the synchronization database to the key value of the previously stored data(305). In case of the actual synchronization target data, the data is stored in a personal information database of the web server(306). The synchronization is performed by downloading the personal information of the web server stored in the personal information database to the second data communication terminal(307).
