Image Encryption:Traditional Methods vs Alternative Methods

Nowadays, securing images is essential because transmissions of images are suffering from various security attacks. Images like medical images, remote-sensing images, etc. have great value both in money and information. Therefore, there are several sophisticated methods for encrypting images. This paper mainly focuses on a survey of such methods and comparative evaluation of them. Here, the reviewers have used 13 papers for the survey and comparative evaluation. Various aspects of image encryption are surveyed and a comparative evaluation of the papers using different parameters such as security attacks, information loss, speed, overhead, etc. is performed. The conclusions are stated with the help of suitable tables. We hope this paper gives an insight into Image Encryption, Encryption Methods, Properties of Images, Evaluation Criteria, Analysis, Attacks, Resistance, Noise, and Information Loss.
