- W4221151285 abstract "This paper presents a review on various image encryption schemes based on fractional transforms for security consideration of image communication. With the enormous increase in the usage of digital media in almost every sphere from education to entertainment, the security of sensitive information has been a concern. Most importantly the user demands for an assured privacy before the information is shared over open network and insecure channels. As image is the most frequently used means of communication in digital scenario, there are various security methods proposed by researchers from time to time. The review is done in two parts. A brief introduction to various optical signal processing-based methods is provided in the beginning which is followed by a conceptual overview of classical DRPE (double random phase encoding) based optical encryption schemes. Some of the recently published relevant reviews and cryptanalysis articles are also analysed. The second part of review is emphasised on the mathematical modelling for encrypting the images in optical transform domain which is main focus of the presented work. Various schemes are classified according to the methodology adopted in each of them. A comparative analysis is presented in tabular form. Based on the observations, the work is converged to a summary on various challenges and some constructive guidelines are provided for consideration in future work. Such a narrative review on encryption algorithm based on various fractional integral transforms in various architectural schematics is not presented before at one place." @default.
