This paper proposes an biometric identification system using data hiding and fingerprint recognition.Recently, the medical image has been digitized by the event of computing and digitization of the medical devices. There are needs for database service of the medical image and future storage due to the development of standards, telemedicine, and et al. Furthermore, authentication and copyright protection are required to guard the illegal distortion and reproduction of the medical information data. during this paper, we propose digital watermarking technique for medical image that forestalls illegal forgery which will be caused after transmitting medical image data remotely. A wrong diagnosis could also be occurred if the watermark is embedded into the entire area of image. Therefore, we embed the watermark into some area of medical image, except the choice area that creates a diagnosis so called region of interest (ROI) area in our paper, to extend invisibility. The watermark is that the value of bit-plane in wavelet transform of the ROI for integrity verification. The bit plane image encryption scheme is proposed for encryption of watermark and implements DWT at fourth level for hiding information using DWT on the duvet image and secret image.
