摘要: The biometric community is faced with the difficult problem of protection original template. One way doing this using a cancelable method, which transforms template in noninvertible and uses transformed to verify person's identity. In paper, we propose two novel representation methods for fingerprint minutiae. Proposed based on are simple generate templates without requiring pre-alignment fingerprints. main idea minimal spanning tree (MST) minutiae three-dimensional (3D) feature space. chain code generated MST two-dimensional (2D) space proposed. A bit string then by mapping into 2D array. upon Cartesian system dealt Method-1, while boundary Method-2. proposed evaluated FVC2004 FVC2002 databases performance better compared existing [C. Lee J.
