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.

Claims

1. A method of operating an electronic device, comprising:

generating a biometric information using at least one sensor included in the electronic device;

storing the biometric information in a memory included in the electronic device;

transmitting, to an external electronic device, at least portion of an address information on a location where the biometric information is stored, wherein the address information is a memory address in the memory;

in response to transmitting the at least portion of the address information, deleting the transmitted at least portion of the address information from the memory, wherein the biometric information remains stored in the memory after the at least portion of the address information is deleted;

detecting an event on the biometric information stored in the memory included in the electronic device;

in response to detecting the event, requesting, to the external electronic device, the at least portion of the address information for accessing the biometric information;

receiving, from the external electronic device, the at least portion of the address information;

identifying, based on the information, the location in the memory; and

in response to identifying the location in the memory, acquiring the biometric information by retrieving the biometric information from the memory in the 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, further comprising, decrypting the biometric information by using association identification of the external electronic device when the biometric information is encrypted.

4. The method of claim 1, further comprising, decrypting the address information by using association identification of the external electronic device when the address information is encrypted.

5. The method of claim 1, further comprising:

receiving, from the external electronic device, the information including the first data segment;

identifying, based on the first data segment and the second data segment, the location in the memory, wherein the second data segment is stored in the memory; and

in response to identifying the location in memory, acquiring the biometric information by retrieving the biometric information from the location in the electronic device.

6. The method of claim 1, further comprising:

generating the biometric information using at least one sensor included in the electronic device;

dividing the biometric information into a third data segment and a fourth data segment;

storing the third data segment in the memory;

transmitting, to the external electronic device authenticated for the biometric information, the fourth data segment of the biometric information; and

in response to transmitting the fourth data segment, deleting the fourth data segment of the address information from the memory.

7. The method of claim 6, further comprising:

receiving, from the external electronic device, the information including the fourth data segment; and

acquiring the biometric information based on the third data segment and the fourth data segment.

8. The method of claim 1, further comprising deleting the information when the external electronic device is disconnected from the electronic device.

9. An electronic device, comprising:

a memory configured to store instructions;

at least one sensor;

at least one processor configured to execute the stored instructions to;

generate a biometric information using the at least one sensor;

store the biometric information in the memory;

transmit, to an external electronic device, at least portion of an address information on a location where the biometric information is stored, wherein the address information is a memory address in the memory;

in response to the transmitting, delete the transmitted at least portion of the address information from the memory, wherein the biometric information remains stored in the memory after the at least portion of the address information is deleted;

detect an event on the biometric information stored in the memory included in the electronic device;

in response to detecting the event, request, to the external electronic device, the at least portion of the address information for accessing the biometric information;

receive, from the external electronic device, the at least portion of the address information;

identify, based on the at least portion of the address information, the location in the memory; and

in response to identifying the location, acquire the biometric information by retrieving the biometric information from the memory in the electronic device.

10. The electronic device of claim 9, 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.

11. The electronic device of claim 9, wherein the at least one processor is further configured to execute the stored instructions to decrypt the biometric information by using association identification of the external electronic device when the biometric information is encrypted.

12. The electronic device of claim 9, wherein the at least one processor is further configured to execute the stored instructions to decrypt the address information by using association identification of the external electronic device when the address information is encrypted.

13. The electronic device of claim 9, wherein the at least one processor is further configured to execute the stored instructions to:

generate the biometric information using at least one sensor included in the electronic device;

store the biometric information at the location in the memory;

divide the address information indicating the location into a first data segment and a second data segment;

transmit, to the external electronic device authenticated for the biometric information, the first data segment of the address information; and

in response to transmitting the first data segment, delete the first data segment of the address information from the memory.

14. The electronic device of claim 13, wherein the at least one processor is further configured to execute the stored instructions to:

receive, from the external electronic device, the information including the first data segment;

identify, based on the first data segment and the second data segment, the location in the memory, wherein the second data segment is stored in the memory; and

in response to identifying the location in memory, acquire the biometric information by retrieving the biometric information from the location in the electronic device.

15. The electronic device of claim 9, wherein the at least one processor is further configured to execute the stored instructions to:

receive, from the external electronic device, the information including the fourth data segment; and

acquire the biometric information based on the third data segment and the fourth data segment.

16. The electronic device of claim 9, wherein the at least one processor is further configured to execute the stored instructions to delete the information when the external electronic device is disconnected from the electronic device.
