Biometric Authentication using Steganography via Chaotic Encryption and Data Hiding

Wireless network becomes omes more popular in transferring sensitive information since it provides many security features such was Protected Access and Wired Equivalent Privacy protocols. Though, it is critical due to many threats such as MAC spoofing, man-in-the-middle attacks, Denial of service, Network injection, Caffe Latte attack, etc. In order to safeguard the information transferred via wireless network, we proposed a method of steganography using chaotic encryption and Qualified Significant wavelet tree (QSWT) concepts. In our proposed system, user gives their face and biometrics (i.e. fingerprint) for authentication. The biometric signal is encrypted and then it is hided into the human face using QSWT technique to produce the stegnoobject. It is then compressed and sent to the server. It aims to prove a) robustness against noise and compression, b) good encryption scheme and c) easy implementation.
