Minutia vicinity representation was recently proposed by Yang & Busch to generate a protected fingerprint template scheme , the resultant protected template enjoys good accuracy and free from alignment. However, Yang and Busche's scheme is highly likely reversible . This paper proposed a new minutiae representation technique known as Minutia Vicinity Decomposition (MVD) whereby each minutia vicinity is decomposed into four minutia triplets. A set of geometrical invariant features can be extracted from the minutia triplet to construct a fingerprint template. The invariant features with random offsets salting mechanism enhance the reversibility, revocability as well as performance accuracy of the resultant protected fingerprint template. Promising experimental results on FVC2002 DB2 justify the feasibility of our proposed technique.
