Abstract

A method for biometric authentication of a user of a mobile device, and a case for performing the method is provided. The method includes, by the case, coupling the mobile device to the case, receiving from the mobile device biometric data of the user of the mobile device that was captured by the mobile device, storing the biometric data, receiving a request from the mobile device for authenticating the user of the mobile device, the request including biometric data captured by the mobile device, comparing the biometric data stored in the case and the biometric data included in the request, and sending to the mobile device a response to the request for authenticating the user of the mobile device based on a result of the comparison, wherein the response to the request is for use by the mobile device to perform an operation based on the authentication of the user.

Claims (11)

1 . A method performed by a mobile device, the method comprising:

controlling, by a first processor of the mobile device, to display on a display of the mobile device a visual indication to input first biometric data via a biometric input device of the mobile device;

capturing, by the biometric input device of the mobile device, the first biometric data;

receiving, by a second processor of the mobile device, the first biometric data that was captured by the biometric input device of the mobile device;

storing, by the second processor of the mobile device, the first biometric data that was captured by the mobile device, wherein the first biometric data that was captured by the mobile device is stored by the second processor of the mobile device in a memory of the mobile device that is associated solely with the second processor of the mobile device;

receiving a request from the first processor of the mobile device, by the second processor of the mobile device, for biometric authentication;

receiving, by the second processor of the mobile device, second biometric data captured by the mobile device;

performing, by the second processor of the mobile device, a comparison between the first biometric data stored in the memory of the mobile device that is associated solely with the second processor of the mobile device and the second biometric data captured by the mobile device;

sending to the first processor of the mobile device, by the second processor of the mobile device, a response to the request for biometric authentication based on a result of the comparison, the response to the request for biometric authentication corresponding to one of successful biometric authentication in case the result of the comparison is that there is a match or unsuccessful biometric authentication in case the result of the comparison is that there is not the match; and

performing, by the first processor of the mobile device, an operation based on the response to the request for biometric authentication received from the second processor of the mobile device,

wherein the first processor and the second processor are fixedly disposed within a single device that is the mobile device.
