Nowadays, security of medical information is more essential because of all the sensitive data of patients are there. To secure that data we provide some securities like watermarking, QR code, etc. In recent years image based information hiding technology has been studied.Recently in hospital we have to send our document to each and every doctor individually. So In this case the communication cost increases. To reduce this cost we will apply selective access control. Using this selective access control we will have to send only one document to hospital and every doctor will decrypt the data based on the key he have. This data will be sending in the form of image using watermarking technique. So no one can easily understand that the data is behind the image and safely we can send it. In watermarking technique we use LSB technique. In Existing LSB technique RGB color format use so in this all Red, Green and Blue color pixel value change. In our modified LSB technique only blue color pixel value is change. If we use modified LSB technique than the image distraction is less and the image look like original image. After that here use QR code generation method. User scan the QR code and get the data safely.
