Abstract
The present disclosure relates to the field of biometric identification of a user, in particular, to a system and method of identifying a user. The method of identifying a user includes: detecting a portion of a user's finger in contact with a touch-sensitive region of a device; and collecting data relating to a fingerprint of the user from the user's finger for a period of time and obtaining a plurality of frames from the data. The method further includes determining whether the user is an authorized user of the device, based on a ridge pattern, a sweat gland pattern, and dynamics of blood circulation in the user's finger as indicated by the data. The method provides an enhanced security system that can be integrated in a user's mobile device to protect against fake biometric characteristics in access control systems.
