DATA SHARING SYSTEM AND METHOD

PROBLEM TO BE SOLVED: To provide a data sharing system capable of carrying out data sharing processing without requiring prior preparation. SOLUTION: A first information processing terminal 200 is provided with: a first detection part for detecting a suspension of work to first data of a first user; a first extraction part for extracting second data shared between the first information processing terminal and a second information processing terminal, from the first data based on operation history when the suspension of work is detected; and a first communication part for transmitting the second data to a server. The second information processing terminal 210 is provided with: a second detection part for detecting a collaborative worker who performs collaborative work with a second user using the second information processing terminal, and a second communication part for transmitting information on the collaborative worker to the server. The server 100 is provided with a second accumulating part for storing the second data, and a third communication part for transmitting the second data to the second information processing terminal upon recognizing the collaborative worker as the first user from the information on the collaborative worker.
