Abstract

A method of operating an electronic device and an electronic device are provided. The method includes generating biometric information using at least one sensor of the electronic device, and storing the generated biometric information in a memory of the electronic device, generating access right information relating to the biometric information, determining whether an external electronic device is connected to the electronic device, and when the external electronic device is connected to the electronic device, transmitting the generated access right information to the external electronic device.

First claim

What is claimed is:

1 . A method of operating an electronic device, comprising:
generating biometric information using at least one sensor of the electronic device, and storing the generated biometric information in a memory of the electronic device; generating access right information relating to the biometric information; determining whether an external electronic device is connected to the electronic device; and when the external electronic device is connected to the electronic device, transmitting the generated access right information to the external electronic device.

2 . The method of claim 1 , wherein the at least one sensor comprises at least one of a fingerprint sensor, an iris sensor, a vein pattern sensor, a voice sensor, and a face sensor.

3 . The method of claim 1 , wherein generating the biometric information using the at least one sensor of the electronic device comprises:
detecting an interrupt signal for registering the biometric information; detecting object information using the at least one sensor in response to the received interrupt signal; and generating the biometric information based on the detected information.

4 . The method of claim 1 , wherein storing the generated biometric information in the memory of the electronic device comprises:
storing the generated biometric information in at least one of a normal area, a secure area, and a share area of the memory.

5 . The method of claim 1 , wherein storing the generated biometric information in the memory of the electronic device comprises:
encrypting the generated biometric information and storing the encrypted biometric information in the memory.

6 . The method of claim 1 , further comprising:
when detecting an access signal for biometric information stored in the memory of the electronic device, determining whether the external electronic device is connected to the electronic device.

7 . The method of claim 6 , further comprising:
when the external electronic device is connected to the electronic device, receiving the access right information relating to the biometric information from the external electronic device; and permitting access to the biometric information stored in the memory of the electronic device based on the received access right information.

8 . The method of claim 1 , further comprising:
dividing the generated biometric information into a plurality of data segments; and transmitting some of the data segments to the external electronic device.

9 . The method of claim 8 , further comprising:
when detecting an access signal for biometric information stored in the memory of the electronic device, receiving a part of the biometric information from the external electronic device connected to the electronic device; and permitting access to the biometric information stored in the memory of the electronic device based on a part of the received access right information.

10 . The method of claim 1 , further comprising:
when the external electronic device connected to the electronic device is a first external electronic device, displaying user authentication of a first security level on a screen of the electronic device; and when the external electronic device connected to the electronic device is a second external electronic device, displaying user authentication of a second security level on the screen of the electronic device, wherein the first security level is higher than the second security level.

11 . An electronic device, comprising:
a memory; at least one sensor; a communication interface; and a processor configured to control the memory, the at least one sensor, and the communication interface, wherein the processor is further configured to generate biometric information using the at least one sensor, store the generated biometric information in the memory, generate access right information relating to the biometric information, determine whether an external electronic device is connected to the electronic device, and when the external electronic device is connected to the electronic device, transmit the generated access right information to the external electronic device through the communication interface.

12 . The electronic device of claim 11 , wherein the at least one sensor comprises at least one of a fingerprint sensor, an iris sensor, a vein pattern sensor, a voice sensor, and a face sensor.

13 . The electronic device of claim 11 , wherein the processor is further configured to detect an interrupt signal for registering the biometric information, detect object information using the at least sensor in response to the received interrupt signal, and generate the biometric information based on the detected information.

14 . The electronic device of claim 11 , wherein the processor is further configured to store the generated biometric information in at least one of a normal area, a secure area, and a share area of the memory.

15 . The electronic device of claim 11 , wherein the processor is further configured to encrypt the generated biometric information and store the encrypted biometric information in the memory.

16 . The electronic device of claim 11 , wherein, when detecting an access signal for biometric information stored in the memory, the processor is further configured to determine whether an external electronic device is connected to the electronic device.

17 . The electronic device of claim 16 , wherein, when the external electronic device is connected to the electronic device, the processor is further configured to receive access right information relating to the biometric information from the external electronic device, and permit access to the biometric information stored in the memory based on the received access right information.

18 . The electronic device of claim 11 , wherein the processor is further configured to divide the generated biometric information into a plurality of data segments and transmit some of the data to the external electronic device.

19 . The electronic device of claim 18 , wherein the processor is further configured to receive a part of the biometric information from the external electronic device connected to the electronic device, and permit access to the biometric information stored in the memory of the electronic device based on a part of the received access right information.

20 . The electronic device of claim 11 , wherein, when the external electronic device connected to the electronic device is a first external electronic device, the processor is further configured to display user authentication of a first security level on a screen of the electronic device, and
when the external electronic device connected to the electronic device is a second external electronic device, the processor is further configured to display user authentication of a second security level on the screen of the electronic device, wherein the first security level is higher than the second security level.
