Information processing system and information processing method

An information processing system comprising a plurality of mobile terminals, and a data management apparatus that is connected to the plurality of mobile terminals via a network;

• wherein
• each of the mobile terminals comprises:
• an authenticating unit that performs user authentication based on inputted authentication information;
• a touch panel unit that displays a user's own page that is a page of the user's own notebook together with a page of another user that is the page of the another user's notebook;
• an input receiving unit that receives writing for copying a copy target area that is selected from the another user's page via the touch panel unit to the user's own page;
• an application executing unit that together with receiving writing by the input receiving unit, is capable of executing at least one application;
• a recording request unit that respectively adds time stamps to the copy-and-paste data received by the input receiving unit and execution contents of each of the at least one application executed by the application executing unit, and as playback data of a written page, transmits a recording request to the data management apparatus;
• an acquisition request unit that, when displaying the written page on the touch panel unit, performs an acquisition request for the playback data of the written page, and receives the playback data from the data management apparatus;
• and
• a playback processing unit that, based on the time stamps, synchronously plays back the copy-and-paste data and the execution contents included in the playback data received by the acquisition request unit;
• the data management apparatus comprises:
• a recording request receiving unit that receives a recording request for the playback data from the mobile terminal;
• a data storage unit that stores the playback data for which a recording request has been received by the recording request receiving unit for each page of the notebook of each user;
• and
• an acquisition request responding unit that searches the data storage unit for the playback data requested to be acquired in response to an acquisition request from the mobile terminal and transmits the playback data to the mobile terminal;
• and
• the recording request receiving unit,
• in the case where a recording request for the copy-and-paste data that is copied from the another user's page is received, copies the playback data of the another user corresponding to the copy target area and stores the playback data in the data storage unit as playback data of user's own page.

An image processing method executed by an information processing system comprising a mobile terminal and a data management apparatus that is connected to the mobile terminal via network;

• whereby
• the mobile terminal:
• displays pages of a notebook on a touch panel unit;
• receives writing on the page via the touch panel unit;
• executes at least one application together with receiving writing;
• respectively adds time stamps to received writing data and execution contents of each of the at least one executed application, and as playback data of a written page, transmits a recording request to the data management apparatus;
• when displaying the written page on the touch panel unit, performs an acquisition request for the playback data of the written page, and receives the playback data from the data management apparatus;
• and
• based on the time stamps, synchronously plays back the writing data and the execution contents included in the received playback data;
• and
• the data management apparatus:
• receives a recording request for the playback data from the mobile terminal;
• stores the playback data for which a recording request has been received for each page of the notebook in a data storage unit;
• and
• searches the data storage unit for the playback data requested to be acquired in response to an acquisition request from the mobile terminal and transmits the playback data to the mobile terminal.
