Abstract

In Recent years there is a rapid growth in wireless technologies, Gega bytes of information has been exchanging over many communication channels. However, few applications like military, medical, multimedia, web and civil etc. need to provide the security to the information sending over. In addition to this, patient’s records in medical images such as Magnetic Resonance (MR) or Computed Tomography (CT) and medical signal reports such as electrocardiogram (ECG) or electro encephalogram (EEG) will be shared among most of the doctors from different branches of health service organizations (HSO) over wireless networks for diagnosis purpose. All these medical images, signals and digital videos may contain some private information, which is more confidential. Hence, it is an important task to provide security for this sort of image and videos. Developing and employing schemes to enhance the lifetime of digital images or videos is an important, imperative, and challenging task, which protects the content of original data for many years. To protect an image or video encryption is an effective approach, which transforms the image or video into different format. In recent years there are so many algorithms that have been developed to provide more security, enhanced quality with easy implementation and faster calculations. Among them all the techniques have their own drawbacks like computational complexity, time consumption and reconstruction of secret information etc.,
