A Fingerprint Watermarking Algorithm to Enhance The Privacy Of Fingerprint Data

Digital watermarking of fingerprint images has been explored to solve the problems of security of data. Biometric data security concerns are receiving the widespread public acceptance of biometric technology. Since a number of security mechanism have been proposed, but due the trade-off between identification efficiency and security of stored template, practical applications have not benefited up to desired level. In this paper, we have designed a watermarking algorithm to improve the recognition performance as well as the security of a fingerprint based biometric system. The proposed algorithm provides the effective solution of security issues regarding biometrics techniques without affecting the fingerprint quality. We have used fingerprint Verification Competition 2004 (FVC 2004) as a database for implementation of proposed algorithm. Experimental results show the efficacy of our algorithm.
