Nowadays, the transmission of digitized medical information has become very convenient due to the generality of Internet. Internet has created the biggest benefit to achieve the transmission of patient information efficiently. However, it is easier that the hackers can grab or duplicate the digitized information on the Internet. This will cause the following problems of medical security and copyright protection. In order to fulfil the security and convenience issues of the patients following goals like the prevention of medical fault, the real-time detection of abnormal event, the support of clinical decision and developing of medical service based on patient has to be achieved. For this purpose this paper proposes the technique called binary embedding technique. It uses the binary information of the text embedded with semi reversible properties in the image are called binary embedding. This technique prevents the distortion of embedded information in the original image due to addition of noise. The concept of semi reversible property is used retains the original information, image quality before and after the process of watermarking is presented as a statistical analysis. © 2009 IEEE.
