SCREEN SHARING SERVER, METHOD OF SHARING SCREEN, AND PROGRAM FOR SCREEN SHARING SERVER

摘要

A screen sharing server receives a connection request each from a sender's user terminal and a receiver's user terminal, receives an authentication number to specify the sender's user terminal with which a screen is to be shared, in response to the connection request, allows the receiver's user terminal to display a prompt to ask for an input of the authentication number, authenticates the authentication number in response to receiving the authentication number from the receiver's user terminal, receives shared screen data from the sender's user terminal and sequentially transfers the shared screen data to the receiver's user terminal, if the authentication number is correct, detects that the sender's user terminal discontinues transmitting the screen data, and makes an inquiry to the receiver's user terminal with an authenticated authentication number about whether or not to transmit the shared screen data, in response to the detection.
