Altered Fingerprint Matching Using Ridge Texture and Frequency in the Unaltered Region
Journal Title: Bonfring International Journal of Advances in Image Processing - Year 2015, Vol 5, Issue 2
Abstract
Fingerprint alteration is the process of changing the regularly spaced ridge structure by mechanical or chemical means to hide the identity from Automated Fingerprint Identification System. This paper presents a method for altered fingerprint matching using texture and ridge frequency in the unaltered region. Wavelet transform is used to create feature vectors from ridge frequency and ridge texture. Matching score obtained for both texture and ridge frequency is fused together to obtain final score. Results of one to many matching between synthetically altered fingerprints and its unaltered mates shows that this method is suitable for altered fingerprint matching
