Abstract

There is provided an authentication device including an extraction unit configured to extract feature data from motion biological information of a person to be authenticated, a calculation unit configured to calculate similarity between the extracted feature data and reference feature data, a determination unit configured to determine whether or not the person to be authenticated is an authorized user on the basis of the calculated similarity, a measurement unit configured to measure a position of the person to be authenticated when an electronic device that expects authentication processing is used as a reference, and an authentication execution unit configured to execute the authentication processing on the basis of the determination result of whether or not the person to be authenticated is the authorized user, and the position of the person to be authenticated.

Claims

1. An authentication device comprising:

an extraction unit configured to extract feature data from motion biological information of a person to be authenticated;

a calculation unit configured to calculate similarity between the extracted feature data and reference feature data;

a determination unit configured to determine whether or not the person to be authenticated is an authorized user on the basis of the calculated similarity;

a measurement unit configured to measure a position of the person to be authenticated when an electronic device that expects authentication processing is used as a reference; and

an authentication execution unit configured to execute the authentication processing on the basis of the determination result of whether or not the person to be authenticated is the authorized user, and the position of the person to be authenticated.

2. The authentication device according to claim 1,

wherein the measurement unit further measures a moving direction of the person to be authenticated, and

wherein the authentication execution unit executes the authentication processing on the basis of the determination result of whether or not the person to be authenticated is the authorized user, the position of the person to be authenticated, and the moving direction of the person to be authenticated.

3. The authentication device according to claim 2,

wherein the measurement unit measures the position of the person to be authenticated on the basis of a received signal strength indicator in radio communication between a terminal device that the person to be authenticated carries, and the electronic device.

4. The authentication device according to claim 2, further comprising:

a login execution unit configured to execute login processing to the electronic device on the basis of a result of the authentication processing.

5. The authentication device according to claim 4,

wherein the authentication execution unit allows the login execution unit to execute logout processing to the electronic device on the basis of the position of the person to be authenticated and the moving direction of the person to be authenticated.

6. The authentication device according to claim 2, further comprising:

an acquisition unit configured to acquire the motion biological information of the person to be authenticated.

7. The authentication device according to claim 6,

wherein the acquisition unit includes at least one of a triaxial acceleration sensor and a gyro sensor.

8. The authentication device according to claim 7,

wherein the motion biological information of the person to be authenticated is walking pattern data.

9. An authentication method of an authentication device, the method comprising:

extracting, by the authentication device, feature data from motion biological information of a person to be authenticated;

calculating, by the authentication device, similarity between the extracted feature data and reference feature data;

determining, by the authentication device, whether or not the person to be authenticated is an authorized user on the basis of the calculated similarity;

measuring, by the authentication device, a position of the person to be authenticated when an electronic device that expects authentication processing is used as a reference; and

executing, by the authentication device, the authentication processing on the basis of the determination result whether or not the person to be authenticated is the authorized user, and the position of the person to be authenticated.

10. A program for allowing a computer to function as:

an extraction unit configured to extract feature data from motion biological information of a person to be authenticated;

a calculation unit configured to calculate similarity between the extracted feature data and reference feature data;

a determination unit configured to determine whether or not the person to be authenticated is an authorized user on the basis of the calculated similarity;

a measurement unit configured to measure a position of the person to be authenticated when an electronic device that expects authentication processing is used as a reference; and

an authentication execution unit configured to execute the authentication processing on the basis of the determination result of whether or not the person to be authenticated is the authorized user, and the position of the person to be authenticated.
