Abstract
A method, a device, and computer-readable medium are provided for verifying an identity of a user, which pertains to computer technology. In some aspects, the method includes generating a dynamic fingerprint while the user moves a finger along a trajectory of movement in a fingerprint collection area of a fingerprint reader, and comparing the dynamic fingerprint with a referential fingerprint. The method also includes verifying the identity of the user based on the comparison, and generating a report indicating the identity verified.
Claims18
A method for verifying an identity of a user, comprising:
- a) generating a dynamic fingerprint while the user moves a finger along a trajectory of movement in a fingerprint collection area of a fingerprint reader;
- b) comparing the dynamic fingerprint with a referential fingerprint;
- c) verifying the identity of the user based on the comparison;
- and
- d) generating a report indicating the identity verified,
- wherein generating the dynamic fingerprint comprises:
- acquiring, using the fingerprint reader, a set of complete fingerprint images corresponding with multiple finger positions along the trajectory of movement;
- and
- combining the set of complete fingerprint images into a composite image representative of the dynamic fingerprint,
- wherein comparing the dynamic fingerprint with the referential fingerprint at step b) comprises:
- comparing one or more fingerprint features with the referential fingerprint features to determine a similarity therebetween;
- and
- wherein the one or more fingerprint features comprise overlapped fingerprint regions between two adjacent complete fingerprints in the composite image.
A device for verifying an identity of a user comprising:
- a fingerprint reader;
- a memory for storing processor-executable instructions;
- a processor programmed to carry out processor-executable instructions to:
- generate a dynamic fingerprint while the user moves a finger along a trajectory of movement in a fingerprint collection area of the fingerprint reader;
- compare the dynamic fingerprint with a referential fingerprint;
- verify the identity of the user based on the comparison;
- and
- generate a report indicating the identity verified;
- and
- an output for displaying the report,
- wherein the processor is further programmed to generate the dynamic fingerprint by acquiring, using the fingerprint reader, a set of complete fingerprint images corresponding with multiple finger positions along the trajectory of movement, and combining the set of complete fingerprint images into a composite image representative of the dynamic fingerprint,
- wherein the processor is further programmed to compare one or more fingerprint features with the referential fingerprint features to determine a similarity therebetween;
- and
- wherein the one or more fingerprint features comprise overlapped fingerprint regions between two adjacent fingerprints in the composite image.
A non-transitory computer-readable medium having recorded thereon instructions, executable by a processor, for verifying an identity of a user with steps comprising:
- a) generating a dynamic fingerprint while the user moves a finger along a trajectory of movement in a fingerprint collection area of a fingerprint reader;
- b) comparing the dynamic fingerprint with a referential fingerprint;
- and
- c) verifying the identity of the user based on the comparison,
- wherein generating the dynamic fingerprint comprises:
- acquiring, using the fingerprint reader, a set of complete fingerprint images corresponding with multiple finger positions along the trajectory of movement;
- and
- combining the set of complete fingerprint images into a composite image representative of the dynamic fingerprint,
- wherein comparing the dynamic fingerprint with the referential fingerprint at step b) comprises:
- comparing one or more fingerprint features with the referential fingerprint features to determine a similarity therebetween;
- and
- wherein the one or more fingerprint features comprise overlapped fingerprint regions between two adjacent fingerprints in the composite image.
