Digital watermarking for Medical Diagnosis

Vol. 17  No. 7  pp. 38-45


Digital watermarking has attained a position of overwhelming interest in image processing research as a new method of protecting multimedia content from unauthorized copying, as the informal transmission and manipulation of digital data creates intimidation for inventors and providers. This paper presents a new watermarking system employing five bit LSB strategy for copyright protection of image contents. The method is based on converting the text information into binary data and representing each character by a length of five bit string and is organized with embedding information into the corresponding image files. The information is being extracted from the images by justifying the least significant bit of eight successive gray values and converting the bits into ASCII characters. The effectiveness of the method has been justified over CT scan, MRI and X-Ray images. Experimental results imply that the proposed algorithm performs better than the traditional LSB method.
