## Abstract

Provided are an identity authentication method, an identity authentication device, and an identity authentication system. The identity authentication method may include transmitting, in response to receiving an authentication signal, a status update request signal to a server to trigger collection of authentication-purpose biometric data, downloading, in response to receiving a message about the collection of the authentication-purpose biometric data, the authentication-purpose biometric data from the server, and comparing the downloaded authentication-purpose biometric data with registered biometric data.

## Claims

### Claim 1

An identity authentication method performed by an identity authentication device, the identity authentication method comprising:
in response to receiving an authentication signal, transmitting a status update request signal to a server to trigger collection of authentication-purpose biometric data;
in response to receiving a message about the collection of the authentication-purpose biometric data, downloading the authentication-purpose biometric data from the server; and
comparing downloaded authentication-purpose biometric data with registered biometric data.

### Claim 2 (depends on 1)

The identity authentication method of claim 1, further comprising transmitting a result value of the comparison to the server.

### Claim 3 (depends on 2)

The identity authentication method of claim 2, wherein the result value is updated by the server and is detected by an identity authentication requesting device monitoring the server.

### Claim 4 (depends on 1)

The identity authentication method of claim 1, wherein the message is a push message.

### Claim 5 (depends on 1)

The identity authentication method of claim 1, wherein the authentication signal is transmitted by an identity authentication requesting device.

### Claim 6 (depends on 1)

The identity authentication method of claim 1, wherein a status of the identity authentication device is updated by the status update request signal, and
the updating of the status is detected by an identity authentication requesting device.

### Claim 7 (depends on 1)

The identity authentication method of claim 1, the authentication-purpose biometric data is deleted after the downloaded authentication-purpose biometric data is compared with the registered biometric data.

### Claim 8

An identity authentication device comprising:
a memory storing at least one program; and
a processor configured to execute the at least one program to transmit, in response to receiving an authentication signal, a status update request signal to a server to trigger collection of authentication-purpose biometric data, download, in response to receiving a message about the collection of the authentication-purpose biometric data, the authentication-purpose biometric data from the server, and compare downloaded authentication-purpose biometric data with registered biometric data.

### Claim 9 (depends on 1)

A computer-readable recording medium having recorded thereon a program for causing a computer to execute the identity authentication method of claim 1.
