Title: Methods, systems and computer program products, for use in biometric authentication
Inventor: TAI CHIU CHAN
IPC: G06V40/12
Filed: 2020-10-23
Abstract: The invention relates to a method of authenticating the identity of a person using biometric data (412, 422) derived from images of a bottom of the fist 202. A plurality of images of the fist are captured (406) while illuminating using one or more light sources (404). New biometric data (412) derived from the captured images is compared (432) directly or indirectly with reference biometric data (422) obtained previously from one or more individuals. Based on the result of said comparing step, an authentication result is provided (436, 438). The biometric data are derived by recognition of features characteristic of the bottom of a fist such as connected lines 232 corresponding to the folds of the little finger. Additional checks (440, 442) for liveness and presence of a real fist are included. The required images could be captured by a display screen of a portable personal device (200), and the fist could be used in clenched or relaxed states.
