Abstract
A security verification apparatus using biometric information and a security verification method are described. The security verification apparatus includes a sensor configured to acquire images of biometric information of a user, and scramble the images of the biometric information by using a received key matrix. The security verification apparatus further includes an information processor configured to generate the key matrix by using a random key, transmit the key matrix to the sensor, decode data of the scrambled images received from the sensor by using the key matrix, and verify the user.
Claims19
A security verification apparatus, comprising:
- a sensor configured to acquire biometric information comprising image data of a user, and scramble the image data using a received key matrix;
- and
- an information processor configured to:
- generate the key matrix using a random key, transmit the key matrix to the sensor, decode the scrambled image data received from the sensor using the key matrix, and verify the user.
A security verification method, comprising:
- generating, by an information processor, a key matrix using a random key;
- scrambling, by a sensor receiving the key matrix, image data comprised of biometric information of a user, in which the image data is scrambled using mask patterns based on the key matrix;
- and
- decoding, by the information processor, the scrambled image data received from the sensor by using the key matrix, and verifying the user based on the decoded image data.
A security verification method, comprising:
- generating, at an image processor, a key matrix using a random key;
- sharing the key matrix with an imager, wherein the imager comprises a sensor configured to obtain a unique biometric identifier of a user;
- encoding, within the sensor, images generated at the imager using the shared key matrix;
- transmitting encoded images to the image processor;
- and decoding encoded images at the image processor using the shared key matrix.
