Abstract

 A motivation for the use of Steganography techniques in biometric systems has been the need to provide increased security to the biometrics data themselves. Fingerprints are unique biometrics mainly used for the establishment of direct personal identity but they are at risk to accidental attacks. Protection of biometric data is one of the most important concerns these days and therefore it is gaining interest among researchers. Many security concerns are raised through the storing and transferring of biometric data, which is sensitive and may be impossible to recover if lost, counterfeited, or hacked.There are two possible domain for fingerprint based stgenography,Spatial domain and Transform domain.Transform based steganography provide more capacity, robustness and security. In transform Domain use discrete wavelet transform,it provide more robustness and capacity. In this Review paper describe about the Fingerprint based Steganography in transform domain.
