Abstract :In recent years, the distribution of digital media files over an open channel using information and communication technology is increasing rapidly. This digital files may contain sensitive information. So providing security, authentication and robustness against attacks are still challenging issue due to attempts of hacking and malicious attacks by an intruder. Watermarking can be an effective solution. Digital image watermarking is hiding secret data inside other multimedia. This paper presents a blind digital image watermarking approach of providing better content authentication and robustness against attacks in medical images. Our approach combines line-column hash function and Digital Signature to enhance authentication which will help additionally in tamper detection. Watermark will be embedded using 3-level DWT and pseudo-random sequence with the session key to get more PSNR ratio.
