With technological advancements, information transfer has become entirely digital, with images serving as a common source of sensitive data. This information must be securely transferred over the internet. This is where image encryption comes into play, and it has been proven to be a very successful method of data transfer in various sectors. In this paper, an efficient algorithm for image encryption is developed where pixel scrambling plays a key role. The encryption method begins with pixel scrambling, which is accomplished by first developing an algorithm for the chaotic map to generate a sequence key. The encrypted image is obtained by applying the generated sequence key to the original image, which is further encrypted using various mathematical computations, such as row and column-wise bit XOR operations, as detailed in the paper. The technique consists of many levels of encryption for securely transmitting data that is vulnerable to cyberattacks. The experimental results demonstrate that the proposed method is efficient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
