Abstract
Presently, there is no solid methodology to protect and secure medical data from health care centers from unauthorized copying. Such as, digital watermarking is gaining interest among research scientists in image processing as a new method of protecting multimedia content from unauthorized copying, as the easy communication and manipulation of digital information create a formidable intimidation for information architects and providers. The main objective of this study is to present a new watermarking system applying a five bit Least Significant Bit (LSB) strategy for copyright security of image contents. The new method commences on converting the text information into binary data by representing each character by a length of five bit string and was organized with embedding information into the corresponding image files. The information is extracted from the images by justifying the LSB of eight successive gray values and converting the bits into ASCII characters. There was no visual difference after embedding watermark using both the traditional and the proposed method.
