Method and system for inputting secret information

摘要

A host computer determines the location of character values in which information on the location in which each of two or more character values distinguishable from each other is arranged on the screen is determined, and sends information on the determined locations to a remote terminal. The remote terminal displays the two or more character values according to the received information, displays a screen pointer and moves the screen pointer in response to a first event. The terminal transmits the information to the host computer in response to a second event. The host computer interprets a character value indicated by the screen pointer at the time when the second event is generated, using location information of the two or more character values determined and information on the screen pointer.
