Satellite images encryption Review

Rapid expansion of digital communication and multimedia application has led to the wide usage of digital image processing in every aspect of life of mankind. These include the use of remote sensing, medical field, meteorology, communications, as well as intelligent robots, just to name a few. This has brought to the issue of security particularly within the domains of storage, communication, as well as transmission of digital data including audio, video and also image. One way to assure image data security is through encryption. The application of encryption can be seen in numerous domains including medical science, military, as well as geographic satellite images. Confidentiality, authenticity, security, privacy and also integrity of image data have become a vital issue for communication and storage of images, especially when dealing with the internet, a channel that is insecure. Accordingly, there have been countless technologies of satellite images encryption being introduced in the recent years. Relevantly, this paper will discuss the notion of cryptography and images encryption. Then, different techniques of satellite images encryption will be discussed and the works associated with each technique will be reviewed. Through the scrutiny of the behavior of a number of satellite images encryption algorithms, this paper will assist in the construction of future satellite images encryption techniques.
