| Summary: | Watermarking biometric data is growing importance and relatively new issue that
used in authentication system. Watermarking is a technique of hiding specific data for copyright authentication. This data can be used to verify the ownership.
Today, with the rapid growth of the Internet, the increased of functionality of
computers and recent developments in fingerprint sensing technology for
acquiring a fingerprint without using the traditional ink and paper make these
image of biometric data (fingerprints) open to the potential attacks during
transmission. Recipients required a mechanism which can prove the accuracy of
their image. If the images are watermarked, it is easy for the owner to verify the
images.
This thesis focuses on the study of watermarking on fingerprint images. A
watermarking technique together with an encryption method to increased a
security of the biometric data especially fingerprints is proposed. Digital
watermark is used to embed information of the owner of the fingerprint image to
protect the intellectual property rights of the fingerprint data. While encryption
technique can be applied to the embedded information for increasing security.
Encryption is the commonest and easiest way to guarantee secure information.
AES (Advance Encryption Standard) has been used in this project. AES is more
reliable not only because its key size is variable over 128 bits but also enhanced
transformation scheme is unpredicted at all.
This thesis provides a comprehensive discussion on the comparison of the digital
watermarking techniques and their desirable features, common method of attacks such as translation, rotation, scaling, resizing, cropping, JPEG compression, noise addition, median filter, histogram equalization and gamma correction. Experimental results demonstrate that the frequency domain scheme is robust to most of the attacks.
Finally, with the application of watermarking method, in which a user’s biometric
data is hiding in the fingerprint image, combining the advantage of encryption
system, the security of the biometric data should be thought of as the means to
eliminate of at least some of the attacks.
