Techniques for biometric authentication of user of mobile device

A method by a mobile device for performing biometric authentication of a user of the mobile device, the method comprising:

• executing, by a first processor of the mobile device, an application for inputting biometric data;
• controlling, by the first processor of the mobile device, to display on a display of the mobile device a visual indication for the user of the of the mobile device to input first biometric data of the user of the mobile device via a biometric input device of the mobile device;
• capturing, by the biometric input device of the mobile device, the first biometric data of the user of the mobile device;
• receiving, by a second processor of the mobile device, the first biometric data of the user of the mobile device 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 of the user of the mobile device that was captured by the mobile device, wherein the first biometric data of the user of the mobile device 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 authenticating the user of the mobile device;
• 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 authenticating the user of the mobile device based on a result of the comparison, the response to the request for authenticating the user of the mobile device including one of an indication that the user of the mobile device is authenticated if the result of the comparison is that there is a match or an indication that the user of the mobile device is not authenticated if 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 authenticating the user of the mobile device 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.
