Authentication method, computer system, server computer and authentication program
First Claim
1. An authentication method for a system including a first computer and a second computer, each having a display surface having a contact recognition function, and for obtaining contact information from a contact with the display surface, one input device configured to make contact with the display surface of the first computer displaying red inkpad information and the display surface of the second computer;
- and a third computer configured to store a permitted value of time when permitting contact by the one input device at the first computer and the second computer as a series of consecutive contacts,the authentication method comprising;
transmitting contact information from the first computer and the second computer by the one input device to the third computer respectively at the first computer and the second computer;
storing values of time based on the first computer and the second computer when contact information is received from the first computer and the second computer respectively in the third computer;
judging whether or not contact information in the second computer corresponds to contact information in the first computer;
if the contact information in the second computer corresponds to the contact information in the first computer, judging whether or not a difference in time obtained from each value of time based on the first computer and the second computer stored in the third computer satisfies the permitted value of the time; and
transmitting viewing information in the third computer based on the red inkpad information displayed on the first computer to the second computer when it is judged that the permitted value is satisfied.

5. A computer system comprising:
-
a first computer and a second computer each having a display surface having a contact recognition function, and for obtaining contact information from a contact with the display surface; one input device configured to make contact with the display surface of the first computer displaying red inkpad information and the display surface of the second computer; and a third computer configured to storing a permitted value of time when permitting contact by the one input device at the first computer and the second computer as a series of consecutive contacts; the first computer including a means for sending contact information on the first computer by the one input device to the third computer, the second computer including a means for sending contact information on the second computer by the one input device to the third computer, the third computer including a means for storing values of time based on the first computer and the second computer when contact information is received from the first computer and the second computer respectively, and a means for judging whether or not the contact information in the second computer corresponds to the contact information in the first computer, if the contact information in the second computer corresponds to the contact information in the first computer, judging whether or not a difference in time obtained from each value of time based on the first computer and the second computer stored in the third computer satisfies the permitted value of the time; and transmitting viewing information in the third computer based on the red inkpad information displayed on the first computer to the second computer when it is judged that the permitted value is satisfied. - View Dependent Claims (6)

7. A server computer comprising:
-
a receiving means configured to receive contact information respectively obtained from a first computer and a second computer arranged with a display surface having a contact recognition function, by contact with the display surface by one input device; a permitted value storage means configured to store a permitted value of time when permitting contact of the one input device in the first computer and the second computer as a series of consecutive contacts; a contact information storage means configured to store with the contact information values of each time respectively based on the first computer and the second computer when contact information from the first computer and the second computer is received respectively; a first judgment means configured to judge whether the contact information in the second computer corresponds to the contact information in the first computer; a second judgment means configured to judge whether or not a difference in time obtained from a value of time based on the first computer and a value of time based on the second computer satisfies a permitted value of the time when it is judged that the contact information in the second computer corresponds to the contact information in the first computer, and a transmission means configured to transmit viewing information to the second computer as a series of consecutive contacts based on the contact information when it is judged that the permitted value of the time is satisfied.

8. A computer usable program product stored on a non-transitory computer usable medium comprising:
-
red inkpad information memory program code configured to store red inkpad information to be displayed on a display surface of a first communication terminal including the display surface having a contact recognition function; first receiving program code configured to receive contact information obtained by contact with the display surface of the first communication terminal by one input device and the red inkpad information; first contact information memory means configured to store a value of time when contact information at the first communication terminal is received by the first receiving program code, the contact information and the red inkpad information; second receiving program code configured to receive contact information obtained from a second communication terminal including a display surface having a contact recognition function by contact with the display surface of the second communication terminal by the one input device; second contact information memory program code configured to store a value of time when contact information at the second communication terminal is received by the second receiving program code and the contact information; first judgment program code configured to judge whether or not the contact information in the second communication terminal received by the second receiving means corresponds to the contact information in the first communication terminal received by the first receiving program code; second judgment program code configured to judge whether or not a difference in time obtained from a value of time based on the first communication terminal and a value of time based on the second communication terminal satisfies a permitted value of time when permitting contact by the one input device at the first communication terminal and the second communication terminal as a series of consecutive contacts when it is judged by the first judgment program code that the contact information in the second communication terminal corresponds to the contact information in the first communication terminal; and viewing information transmission program code configured to transmit the viewing information to the second communication terminal based on the red inkpad information when it is judged that the permitted value is satisfied by the second judgment terminal.
