Techniques for biometric authentication of user of mobile device

1. A method for biometric authentication of a user of a mobile device, the method comprising:

coupling the mobile device to a case for the mobile device;

receiving from the mobile device, by the case, biometric data of the user of the mobile device that was captured by the mobile device and identification data of the mobile device;

storing, by the case, the biometric data of the user of the mobile device and the identification data of the mobile device that was received from the mobile device and a biometric pin, wherein the case is configured to only store one time the biometric data of the user of the mobile device and the identification data of the mobile device that was received from the mobile device and the biometric pin;

receiving a request from the mobile device, by the case, for authenticating the user of the mobile device, the request including biometric data captured by the mobile device and identification data of the mobile device;

performing, by the case, a first comparison between the biometric data stored in the case and the biometric data included in the request, and a second comparison between the identification data of the mobile device stored in the case and the identification data of the mobile device included in the request; and

sending to the mobile device, by the case, a response to the request for authenticating the user of the mobile device based on a result of both the first comparison and the second comparison, the response to the request for authenticating the user of the mobile device including the biometric pin if the result of both the first comparison and the second comparison is that there is a match,

wherein the response to the request for authenticating the user of the mobile device is for use by the mobile device to perform an operation based on the authentication of the user.

2. The method of claim 1 , wherein the identification data of the mobile device includes a serial number, an International Mobile Equipment Identity (IMEI), and an Integrated Circuit Card Identifier (ICCID).

3. The method of claim 1 , wherein the coupling of the mobile device to the case for the mobile device comprises at least one of a physical and communication coupling.

4. The method of claim 1 , wherein the case receives from the mobile device and sends to the mobile device through at least one of a wireless and a wired communication.

5. The method of claim 4 , wherein the wireless communication is a Near Field Communication (NFC) communication.

6. The method of claim 1 , wherein the operation performed by the mobile device based on the authentication of the user comprises at least one of a network login, a device login, and a financial transaction.

7. The method of claim 1 , wherein the biometric data comprises at least one of a single fingerprint, a multiple finger fingerprint, a palm print, an iris scan, a voiceprint, a facial recognition without motion adjustment, a facial recognition with motion adjustment, a repeatable motion, a repeatable key input, and a repeatable touchscreen input.

8. The method of claim 1 , further comprising emulating, by the case, at least one of a contactless card and a credit card.

9. The method of claim 1 , wherein if the user of the mobile device is authenticated, the mobile device displays on a display at least one of an image and alphanumeric characters for identifying the user of the mobile device.

10. The method of claim 1 , wherein the case has printed thereon or embedded therein at least one of an image and alphanumeric characters that is visible from the outside for identifying the user of the mobile device.

11. The method of claim 10 , wherein if the user of the mobile device is authenticated, the mobile device displays on a display the at least one of the image and alphanumeric characters printed on or embedded in the housing.

12. A case for a mobile device for biometric authentication of a user of the mobile device, the case comprising:

a housing configured to removably retain the mobile device, the housing including a memory, a communication unit, and a processor unit;

the memory configured to only store one time biometric data of a user of the mobile device, identification data of the mobile device, and a biometric pin;

the communication unit configured to communicate with the mobile device; and

the processor unit configured to communicate and control the memory and the communication unit to:

receive from the mobile device biometric data of the user of the mobile device that was captured by the mobile device and identification data of the mobile device,

store one time the biometric data of the user of the mobile device and the identification data of the mobile device that was received from the mobile device and the biometric pin,

receive a request from the mobile device for authenticating the user of the mobile device, the request including biometric data captured by the mobile device and identification data of the mobile device,

perform a first comparison between the biometric data stored in the case and the biometric data included in the request, and a second comparison between the identification data of the mobile device stored in the case and the identification data of the mobile device included in the request, and

send to the mobile device a response to the request for authenticating the user of the mobile device based on a result of both the first comparison and the second comparison, the response to the request for authenticating the user of the mobile device including the biometric pin if the result of both the first comparison and the second comparison is that there is a match,

wherein the response to the request for authenticating the user of the mobile device is for use by the mobile device to perform an operation based on the authentication of the user.

13. The case of claim 12 , wherein the identification data of the mobile device includes a serial number, an International Mobile Equipment Identity (IMEI), and an Integrated Circuit Card Identifier (ICCID).

14. The case of claim 12 , wherein the communication unit is configured to communicate with the mobile device through at least one of a wireless and a wired communication.

15. The case of claim 14 , wherein the wireless communication is a Near Field Communication (NFC) communication.

16. The case of claim 12 , wherein the operation performed by the mobile device based on the authentication of the user comprises at least one of a network login, a device login, and a financial transaction.

17. The case of claim 12 , wherein the biometric data comprises at least one of a single fingerprint, a multiple finger fingerprint, a palm print, an iris scan, a voiceprint, a facial recognition without motion adjustment, a facial recognition with motion adjustment, a repeatable motion, a repeatable key input, and a repeatable touchscreen input.

18. The case of claim 12 , wherein the case further includes a card emulator for emulating at least one of a contactless card and a credit card.

19. The case of claim 12 , wherein if the user of the mobile device is authenticated, the mobile device displays on a display at least one of an image and alphanumeric characters for identifying the user of the mobile device.

20. The case of claim 12 , wherein the housing has printed thereon or embedded therein at least one of an image and alphanumeric characters that is visible from the outside for identifying the user of the mobile device.

21. The case of claim 20 , wherein if the user of the mobile device is authenticated, the mobile device displays on a display the at least one of the image and alphanumeric characters.
