If the user's selection of the item displayed on the display unit 151 is recognized in step S140, the control unit 180 of the mobile terminal 100 displays the change in the shared data on the display unit 151 S150). Then, the user can specifically confirm the change of the shared data.

Other examples of registration of shared data performed in step S100 will be described. If the shared data is constant data, the information sharer can register the shared data in the data server 200 by utilizing the importance function of the schedule application or utilizing the separately provided interest data registration function. Here, the user can set only a part of fields such as the place and time included in the schedule data as shared data by using a separate menu. That is, the shared data may be the entirety of the specific data or a part thereof.

If the shared data is a photograph or a moving picture, the information sharer can register the shared data using a separate menu for registering shared data provided by his / her terminal or the data server 200. [ At this time, the user can register only a part of fields such as photograph, video title, GPS information, etc. as shared data.

If the shared data is a document, the information sharer may register the shared data using his or her terminal or the shared data registration menu provided by the data server 200. At this time, the user can sort the document by type and set it as shared data, or only a part of the document can be registered as shared data.

First, the user of the mobile terminal 100 registers a change alarm of the shared data and other shared data associated with the shared data to the data server 200 (S200). Once we look at an example of other shared data associated with shared data. If the shared data is constant data, it may be the other shared data associated with the shared data.

Then, the mobile terminal 100 receives the data change content from the data server 200 (S210) and determines whether the shared data has been changed (S220). If the shared data is changed, the control unit 180 of the mobile terminal 100 displays the first item on the display unit 151 indicating that the shared data has been changed (S230). Then, if the first item is selected, the change of the shared data is displayed on the display unit 151 (S240).

However, when the changed data is not shared data, the controller 180 determines whether the changed data is another shared data related to the shared data (S250). If the shared data that is related to the shared data is changed, the controller 180 displays a second item indicating the change of the other shared data on the display unit 151 (S260). Then, when the second item is selected, the change of the other shared data is displayed on the display unit 151 (S270).

A more detailed example of other shared data associated with the shared data briefly discussed in step S200 will be discussed. If the contact information is shared data, the other shared data associated with the contact information includes other contact information of the group to which the contact belongs, a photograph containing the person, an email sent by the person, a schedule related to the person, It may be other shared data associated with it.

When the schedule information is shared data, the contact related to the schedule data, the email related to the schedule, and the like may be other shared data related to schedule information.

If the document is shared data, other documents in the folder that the document is in, documents created or modified at a similar time, emails attached to the document, original documents in the document, contacts associated with the document, It can be other shared data.
