Abstract

Medical imaging is a sensitive and important type of data that requires robust encryption to protect it during transmission over networks. Confidentiality is a critical aspect to consider when securing information systems, and encryption techniques. These images have unique characteristics, including large data size, redundancies, and similarities between neighboring pixels, making them different from text. To confirm the security of medical images and prevent unauthorized access or manipulation, highly secure algorithms are necessary due to the rapid advancement of network technologies. This survey aims to explain the different methods currently used to protect medical data, such as encryption, steganography, steganography, and methods of hiding, as well as the difference between full encryption of the medical image and partial encryption only of the important sections of the images. In order to arrive at the most effective approach, a number of prior experiences and studies were used. This article discusses recent advancements in this field, highlighting the need for secure encryption schemes to withstand adversarial attacks and ensure the confidentiality of medical images.
