Registration-based cancelable template schemes rely on accurate fingerprint image alignment, which is very difficult to achieve. In this paper, by exploiting pair-minutiae vectors, we develop a lightweight, alignment-free scheme for generating cancelable fingerprint templates. The proposed mathematical model is based on a densely infinite-to-one mapping (DITOM) aiming to achieve the non-invertible property. The transformation designed describes the intersection of a collection of hyperplanes and effectively realizes infinite-to-one mapping. The proposed scheme has the properties of non-invertibility, revocability and multiple template independence. Evaluation of the proposed scheme over FVC2002 DB1, DB2 and DB3 shows that the new method exhibits satisfactory performance compared to existing methods.
► Alignment-free cancelable fingerprint templates.
► Densely infinite-to-one mapping (DITOM) based on non-invertible transformation.
► Secrecy of original fingerprint data guaranteed.
► Low equal error rate (EER).
► Generated cancelable templates have the properties of non-invertibility, revocability and multiple template independence.
