System, data providing method and electronic apparatus

A data providing method comprising:

• receiving a plurality of stroke data, which correspond to a plurality of strokes handwritten on first contents in a plurality of terminals, from the plurality of terminals;
• storing the plurality of stroke data in a storage medium, the plurality of stroke data associated with an identifier of a terminal which is a sender;
• and
• transmitting to a first terminal of the plurality of terminals one or more first stroke data of the plurality of stroke data, the one or more first stroke data being associated with an identifier of a terminal other than the first terminal.

A computer-readable, non-transitory storage medium having stored thereon a computer program which is executable by a computer, the program controlling the computer to execute functions of:

• receiving a plurality of stroke data, which correspond to a plurality of strokes handwritten on first contents in a plurality of terminals, from the plurality of terminals;
• storing the plurality of stroke data in a storage medium, the plurality of stroke data associated with an identifier of a terminal which is a sender;
• and
• transmitting to a first terminal of the plurality of terminals one or more first stroke data of the plurality of stroke data, the one or more first stroke data being associated with an identifier of a terminal other than the first terminal.

An electronic apparatus comprising:

• a transmitter configured to transmit to a system first stroke data corresponding to a first stroke which is handwritten on first content displayed on a display of the electronic apparatus;
• a receiver configured to receive from the system second stroke data corresponding to a second stroke which is handwritten on first content displayed on a display of another terminal;
• and
• a drawing process module configured to draw the second stroke on the first content displayed on the display of the electronic apparatus, based on the second stroke data.
