A Secure Internet-Based Personal Identity Verification System Using Lossless Watermarking and Fingerprint Recognition

Abstract

This paper proposes an internet-based personal identity verification system using lossless data hiding and fingerprint recognition technologies. At the client side, the SHA-256 hash of the original fingerprint image and sensitive personal information are encrypted and embedded into the fingerprint image using an advanced lossless data hiding scheme. At the service provider side, after the hidden data are extracted out, the fingerprint image can be recovered without any distortion due to the usage of the lossless data hiding scheme. Hence, the originality of the fingerprint image can be ensured via hash check. The extracted personal information can be used to obtain the correct fingerprint feature from the database. The fingerprint matching can finally verify the client’s identity. The experimental results demonstrate that our proposed system is effective. It can find wide applications in e-banking and e-government systems to name a few.
