Abstract

System and method are disclosed for providing authentication of a terminal device. One embodiment includes a method implemented by a first terminal device. The method may include receiving first location information and receiving a first predetermined signal. The method may also include transmitting status information and the first location information to a server upon receiving the first predetermined signal to allow the server to compare the first location information with second location information received from a second terminal device and to allow the server to transmit the status information to the second terminal device. The status information may indicate that the first terminal device is authenticated and the first location information may indicate a current location of the first terminal device.

First claim

What is claimed is:

1 . A method, implemented by a first terminal device, for providing authentication on a second terminal device, the method comprising:
receiving, by a processor device of the first terminal device, first location information; receiving, by the processor device, a first predetermined signal; and transmitting status information and the first location information to a server upon receiving the first predetermined signal to allow the server to compare the first location information with second location information received from the second terminal device and to allow the server to transmit the status information to the second terminal device, wherein the status information indicates that the first terminal device is authenticated and the first location information indicates a current location of the first terminal device.

2 . The method of claim 1 , comprising:
detecting, by a motion detection device of the first device, a sudden change of a direction of motion of the first terminal device; and generating, by the motion detection device, the first predetermined signal based on the detected sudden change.

3 . The method of claim 1 , comprising:
detecting a pressing of a predetermined key of the first terminal device; and generating the first predetermined signal based on the detected pressing of the predetermined key.

4 . The method of claim 1 , comprising:
receiving, from the server, an identification code indicating an identity of the second terminal device; and displaying the identification code on a display device of the first terminal device.

5 . The method of claim 4 , comprising:
receiving an input indicating a selection of the identification code; and transmitting the selected identification code to the server.

6 . A method, implemented by a processor device of a server, for providing authentication, the method comprising:
receiving, from a first terminal device, status information and first location information, wherein the status information indicates that the first terminal device is authenticated and the first location information indicates a current location of the first terminal device; receiving, from a second terminal device, second location information indicating a current location of the second terminal device; comparing the first and second location information to determine whether the current locations of the first and second terminal devices are substantially the same; and when it is determined that the current locations of the first and second terminal devices are substantially the same, transmitting the status information to the second terminal device to authenticate the second terminal device.

7 . The method of claim 6 , comprising:
generating an identification code indicating an identity of the second terminal device; and transmitting the identification code to at least one of the first or second terminal device.

8 . The method of claim 7 , comprising:
receiving, from at least one of the first or second terminal device, the identification code; and transmitting the status information to the second terminal device indicated by the received identification code.

9 . The method of claim 6 , comprising:
receiving a first time stamp from the first terminal device; receiving a second time stamp from the second terminal device; comparing the first and second time stamps to determine a difference between the first and second time stamps; and transmitting the status information to the second terminal device when the difference between the first and second time stamps is within a predetermined range.

10 . A terminal device, comprising:
a transceiver device that transmits or receives information from a server; and a processor device that:
receives first location information;
receives a first predetermined signal; and
controls the transceiver to transmit status information and the first location information to the server upon receiving the first predetermined signal to allow the server to compare the first location information with second location information received from a second terminal device and to allow the server to transmit the status information to the second terminal device, wherein the status information indicates that the first terminal device is authenticated and the first location information indicates a current location of the first terminal device.

11 . The terminal device of claim 10 , comprising:
a motion detection device that:
detects a sudden change of a direction of motion of the first terminal device; and
generates the first predetermined signal based on the detected sudden change.

12 . The terminal device of claim 10 , comprising:
a keyboard controller that:
detects a pressing of a predetermined key of the first terminal device; and
generates the first predetermined signal based on the detected pressing of the predetermined key.

13 . The terminal device of claim 10 , comprising a display device and wherein the processor device:
controls the transceiver to receive, from the server, an identification code indicating an identity of the second terminal device; and controls the display device to display the identification code on a display device of the first terminal device.

14 . The terminal device of claim 13 , wherein the processor device:
receives an input indicating a selection of the identification code; and controls the transceiver to transmit the selected identification code to the server.

15 . A server, comprising:
a transceiver device that transmits or receives information from first and second terminal devices; and a processor device that:
receives, from a first terminal device, status information and first location information, wherein the status information indicates that the first terminal device is authenticated and the first location information indicates a current location of the first terminal device;
receives, from a second terminal device, second location information indicating a current location of the second terminal device;
compares the first and second location information to determine whether the current locations of the first and second terminal devices are substantially the same; and
when it is determined that the current locations of the first and second terminal devices are substantially the same, control the transceiver to transmit the status information to the second terminal device to authenticate the second terminal device.

16 . The server of claim 15 , wherein the processor device:
generates an identification code indicating an identity of the second terminal device; and controls the transceiver device to transmit the identification code to at least one of the first or second terminal device.

17 . The server of claim 16 , wherein the processor device:
controls the transceiver to receive, from at least one of the first or second terminal device, the identification code; and controls the transceiver to transmit the status information to the second terminal device indicated by the received identification code.

18 . The server of claim 15 , wherein the processor device:
controls the transceiver to receive a first time stamp from the first terminal device; controls the transceiver to receive a second time stamp from the second terminal device; compares the first and second time stamps to determine a difference between the first and second time stamps; and controls the transceiver to transmit the status information to the second terminal device when the dif
