Abstract
The present invention provides fingerprint-based verification system and fingerprint identification method. The fingerprint-based verification system verifies identify by analyzing biometric minutiae including the ridges and pores on a fingerprint. The fingerprint identification method comprises a step for obtaining a first fingerprint, a step for obtaining a second fingerprint, and a step for comparing the first fingerprint and the second fingerprint. The present invention provides effective systems and methods for mitigating identity fraud.
Claims15
A method for identifying fingerprints, comprising:
- obtaining a first fingerprint image from a first subject;
- extracting a first ridge-based information and a first pore-based information from the first fingerprint image, wherein the first pore-based information comprises a first descriptor;
- obtaining a second fingerprint image from a second subject;
- extracting a second ridge-based information and a second pore-based information from the second fingerprint image, wherein the second pore-based information comprises a second descriptor;
- generating a ridge similarity score by comparing the first ridge-based information and the second ridge-based information;
- generating a pore similarity score by comparing the first pore-based information and the second pore-based information;
- and
- determining the identity of the second subject based on the ridge similarity score and the pore similarity score.
A method for mitigating identity fraud, comprising:
- obtaining a first fingerprint image from a first subject;
- extracting a first pore-based information from the first fingerprint image, wherein the first pore-based information comprises a first descriptor;
- obtaining a second fingerprint image from a second subject;
- extracting a second pore-based information from the second fingerprint image, wherein the second pore-based information comprises a second descriptor;
- generating a pore similarity score by comparing the first pore-based information and the second pore-based information;
- and
- determining whether the pore similarity score satisfies a pre-determined value.
