Identity authentication request method, identity authentication request device, and identity authentication system

1 . An identity authentication request method comprising the steps of:

detecting an approaching person and collecting an authentication means data;

transmitting a prearranged sound signal, in response to collecting the authentication means data;

receiving device identification data transmitted from a device that has detected the prearranged sound signal; and

transmitting the collected authentication means data to a device identified by the device identification data.

2 . The identity authentication request method of claim 1 , further comprising the steps of:

receiving success or failure of identity authentication; and

approving or disapproving access to a restricted procedure through identity authentication, based on the success or failure of the identity authentication.

3 . The identity authentication request method of claim 1 , further comprising the step of, when the device identification data includes a plurality of pieces of device identification data, selecting one of the plurality of pieces of device identification data,

wherein the collected authentication means data is transmitted to a device identified by the one selected device identification data.

4 . The identity authentication request method of claim 3 , wherein the step of selecting one of the plurality of pieces of device identification data comprises the step of receiving an input of selecting one of the plurality of pieces of device identification data.

5 . The identity authentication request method of claim 1 , wherein, when the device identification data includes a plurality of pieces of device identification data, the step of transmitting the collected authentication means data to the device identified by the device identification data comprises the step of transmitting the collected authentication means data to each of a plurality of devices identified by the plurality of pieces of device identification data.

6 . The identity authentication request method of claim 1 , wherein the prearranged sound signal comprises a sound having a frequency value that is not included in an audible frequency.

7 . An identity authentication request device comprising:

a memory in which at least one program is stored; and

a processor configured to be operated by executing the at least one program,

wherein the processor is further configured to:

detect an approaching person and collect an authentication means data;

transmitting a prearranged sound signal, in response to collecting the authentication means data;

receive device identification data transmitted from a device that has detected the prearranged sound signal; and

transmit the collected authentication means data to a device identified by the device identification data.

8 . A non-transitory computer-readable recording medium having recorded thereon a program for causing a computer to perform the steps of:

detecting an approaching person and collecting an authentication means data;

transmitting a prearranged sound signal, in response to collecting the authentication means data;

receiving device identification data transmitted from a device that has detected the prearranged sound signal; and

transmitting the collected authentication means data to a device identified by the device identification data.

9 . An identity authentication method comprising the steps of

detecting an approaching person and collecting an authentication means data;

transmitting device identification data in response to detecting a prearranged sound signal, wherein the prearranged sound signal is transmitted in response to collecting the authentication means data;

receiving transmitted authentication means data, based on the transmitted device identification data;

determining whether the authentication means data matches stored identity authentication data; and

transmitting success or failure of identity authentication, based on the matching or mismatching.
