Methods and systems for capturing biometric data
A method of capturing biometric data is provided that includes calculating, by a terminal device, an angle between a surface of the terminal device and an X-axis of the terminal device. When the angle is other than ninety degrees, a prompt is displayed on the terminal device that is designed to cause a terminal device user to adjust the position of the terminal device into an optimal position. After adjusting the position of the terminal device, the terminal device calculates the angle and when the angle is ninety degrees the terminal device captures biometric data from the user.
1. A method of capturing biometric data comprising:
generating, by an accelerometer and gyroscope included in a terminal device, data regarding rotation and translation of the terminal device;
calculating, by the terminal device, based on the generated data, an angle between a surface of the terminal device and an X-axis of the terminal device;
when the angle is other than ninety degrees, displaying, by the terminal device an image of a biometric modality of a user, a first pair of parallel lines, and a second pair of parallel lines;
moving the first pair of parallel lines to overlap the second pair of parallel lines as the terminal device is moved into an optimal position in response to said displaying step, wherein each pair of parallel lines delimits the dimensions of the image in the optimal position; and
when the first and second pairs of parallel lines overlap, capturing, by the terminal device, biometric data from the user.
2. A method of capturing biometric data in accordance with claim 1 , said capturing step further comprising capturing biometric data from the user when the terminal device is at about the same height as the face of the user.
3. A method of capturing biometric data in accordance with claim 1 , said capturing step comprising capturing face biometric data.
4. A terminal device for capturing biometric data comprising:
an accelerometer;
a gyroscope;
a processor; and
a memory for storing data, said terminal device being associated with a network and said memory being in communication with said processor and having instructions stored thereon which, when executed by said processor, cause said terminal device to:
receive from said accelerometer and gyroscope data regarding rotation and translation of said terminal device;
calculate, based on the received data, an angle between a surface of said terminal device and an X-axis of said terminal device;
when the angle is other than ninety degrees, display an image of a biometric modality of a user, a first pair of parallel lines, and a second pair of parallel lines;
move the first pair of parallel lines to overlap the second pair of parallel lines as the terminal device is moved into an optimal position in response to displaying the lines, wherein each pair of parallel lines delimits the dimensions of the image in the optimal position; and
when the first and second pairs of parallel lines overlap, capturing, by the terminal device, biometric data from the user.
5. A terminal device in accordance with claim 4 , wherein the instructions when executed by said processor further cause said terminal device to capture biometric data from the user when said terminal device is at about the same height as the face of the user.
6. A non-transitory computer-readable recording medium included in a terminal device having a computer program recorded thereon for enabling increased trustworthiness of biometric authentication transaction results, the computer program being comprised of instructions, which when read and executed by the terminal device, cause the terminal device to:
receive from an accelerometer and a gyroscope included in the terminal device, data regarding rotation and translation of the terminal device;
calculate, based on the received data, an angle between a surface of the terminal device and an X-axis of the terminal device;
when the angle is other than ninety degrees, display an image of a biometric modality of a user, a first pair of parallel lines, and a second pair of parallel lines;
move the first pair of parallel lines to overlap the second pair of parallel lines as the terminal device is moved into an optimal position in response to displaying the lines, wherein each pair of parallel lines delimits the dimensions of the image in the optimal position; and
when the first and second pairs of parallel lines overlap, capturing, by the terminal device, biometric data from the user.
7. A non-transitory computer-readable recording medium in accordance with claim 6 , wherein the instructions when read and executed by the terminal device further cause the terminal device to capture biometric data from the user when the terminal device is at about the same height as the face of the user.
