Abstract

A mobile communication terminal having a security function using biological information for authentication includes: authentication units for performing authentication based on at least two kinds of biological information; and a control unit for performing operational control of the authentication units. The control unit has a function of proceeding with capturing of biological information and authentication processing based on the captured biological information, performed for the respective kinds of biological information by the authentication units, in parallel.

Claims

1. A mobile communication terminal having a security function using biological information for authentication, comprising:

authentication units for performing authentication based on at least two kinds of biological information; and

a control unit for controlling operation of the authentication units, wherein

the control unit has a function of proceeding with capturing of the biological information and authentication processing based on the biological information captured, performed for respective kinds of biological information by the authentication units, in parallel.

2. The mobile communication terminal, as claimed in claim 1, wherein the authentication units include at least an iris authentication unit for performing authentication based on biological information of iris, and

a camera of the iris authentication unit is also used as a camera for capturing image data with visible light to be provided in the mobile communication terminal.

3. The mobile communication terminal, as claimed in claim 2, wherein the camera of the iris authentication unit has a filter mechanism which transmits visible light and an infrared ray by switching between them.

4. The mobile communication terminal, as claimed in claim 3, wherein an infrared ray irradiation mechanism used for capturing authentication data by the iris authentication unit is also used for data communications.

5. The mobile communication terminal, as claimed in claim 1, wherein the authentication units include at least a vein authentication unit for performing authentication based on biological information of vein, and

a camera of the vein authentication unit is also used as a camera for capturing image data with visible light to be provided in the mobile communication terminal.

6. The mobile communication terminal, as claimed in claim 5, wherein the camera of the vein authentication unit has a filter mechanism which transmits visible light and an infrared ray by switching between them.

7. The mobile communication terminal, as claimed in claim 6, wherein an infrared ray irradiation mechanism used for capturing authentication data by the vein authentication unit is also used for data communications.

8. The mobile communication terminal, as claimed in claim 1, wherein the authentication units include an iris authentication unit and a vein authentication unit for performing authentication based on biological information of iris and vein, and

a camera of one of the iris authentication unit and the vein authentication unit is also used as a camera for capturing image data with visible light to be provided in the mobile communication terminal.

9. The mobile communication terminal, as claimed in claim 8, wherein the camera of the iris authentication unit or the vein authentication unit has a filter mechanism which transmits visible light and an infrared ray by switching between them.

10. The mobile communication terminal, as claimed in claim 9, wherein an infrared ray irradiation mechanism used for capturing authentication data by the iris authentication unit and the vein authentication unit is also used for data communications.

11. The mobile communication terminal, as claimed in claim 1, wherein the authentication units include at least an iris authentication unit for performing authentication based on biological information of iris, and

an infrared ray irradiation mechanism used for capturing authentication data by the iris authentication unit is also used for data communications.

12. The mobile communication terminal, as claimed in claim 1, wherein the authentication units include at least a vein authentication unit for performing authentication based on biological information of vein, and

an infrared ray irradiation mechanism used for capturing authentication data by the vein authentication unit is also used for data communications.

13. The mobile communication terminal, as claimed in claim 1, wherein the authentication units include at least an iris authentication unit and a vein authentication unit for performing authentication based on biological information of iris and vein, and

an infrared ray irradiation mechanism used for capturing authentication data by one of the iris authentication unit and the vein authentication unit is also used for data communications.

14. An authentication method in a mobile communication terminal comprising the steps of:

capturing data of different kinds of biological information of a user handling the mobile communication terminal; and

performing authentication based on the biological information captured in the step of capturing;

wherein

capturing of the biological information and authentication processing based on the biological information captured, performed for respective kinds of biological information, are proceeded in parallel.

15. An authentication program in a mobile communication terminal for prompting a microprocessor incorporated in the mobile communication terminal to execute:

functions of authentication units to perform authentication based on at least two kinds of biological information; and

a function of a control unit having a function to proceed with capturing of the biological information and authentication processing based on the biological information captured, performed for respective kinds of biological information by the authentication units, in parallel.
