Patient Watermarking

The protection of the information is considered a big challenge for all the systems, which manage fragile information of their clients. As a result, the systems should provide security that permits people to trust in their companies and services. Nowadays, the technological environment offers many algorithms and methods that permit to keep the information safe. One of the recent innovation is watermarking. Watermarking is a security method that help people to keep the information protected against unauthorized viewers. These methods are used in some applications, which included copyright protection, fingerprinting, authentication, copy control, tamper detection, and data hiding applications such as broadcast monitoring. In medical areas, the images are considered as a useful source of information. They not only have the image; but also can be watermark the details about the condition of their patients without losing the quality of pictures. In addition, this method not only helps us to keep the information secret, it also helps to save storage space. Also in medical procedures, it is necessary that specialists in many areas …show more content…
The multiple watermarking scheme has two parts. An annotation scheme and a fragile scheme. The annotation scheme encrypts all of the patient’s personal data such as name, medical records etc. in a much secure way. For the annotation scheme we have chosen Wavelet-based watermarking method since the visual quality of the watermarked images are high as it achieves high PSNR values. Furthermore, it is a blind scheme because the original image is not needed to extract the secret information. This eliminates the need for storing the patient's information in plain text as we can reduce the storage space by embedding the patient's information onto the
