Medical image encryption techniques: a technical survey and potential challenges

Abstract

<span lang="EN-US">Among the most sensitive and important data in telemedicine systems are medical images. It is necessary to use a robust encryption method that is resistant to cryptographic assaults while transferring medical images over the internet. Confidentiality is the most crucial of the three security goals for protecting information systems, along with availability, integrity, and compliance. Encryption and watermarking of medical images address problems with confidentiality and integrity in telemedicine applications. The need to prioritize security issues in telemedicine applications makes the choice of a trustworthy and efficient strategy or framework all the more crucial. The paper examines various security issues and cutting-edge methods to secure medical images for use with telemedicine systems.</span>

Hybrid Security Model for Medical Image Protection in Cloud

“…The researchers in 2023 demonstrated that the encryption of medical images and records and protecting the patient's privacy are legal responsibilities that the existing algorithms may not achieve optimally [16].…”

“…The model makes use of both symmetric and uneven encryption calculation (AES and ECC) to enhance information security against intruders, preventing illegal access to natural resources, improving privacy and time taken to perform cryptographic tasks, and further developing the trust level of the client in the cloud and accelerating the use of more modest keys of ECC in the cryptographic interaction. Table 1 represents the comparative analysis of related work in detail papers [14][15][16][17][18][19][20] Table 1: Comparative analysis of related work Refs.…”

“…[15] A hybrid encryption system was employed to secure data in the cloud's Software as a Service (SaaS) model, utilizing Receive Side Scaling (RSS) and ECC security algorithms. [16] The paper examines various security issues and cutting-edge methods to secure medical images for use with telemedicine systems. [17] A modified AES algorithm has been developed and found to be more secure than the standard AES algorithm for small files.…”

Mobile design for medical care and minor emergencies applying telemedicine

“…Nowadays we have many patients with discomfort in their care and this is reflected in any health center in the world, medical congestion is very frequent since the long waiting list in health centers can be a delay and problem for doctors, surgeries, or consultations with specialists are a headache for patients who require short and urgent care [1]. Lack of specialists contributes to a major problem, showing patient overload and great difficulty in medical care [2]- [5]. India has a high population density in its health services which are overloaded with patients, showing a total collapse in hospitals and more so for COVID-19 diseases or similar symptoms treated in health centers [6].…”

Improved Vigenere approach incorporating pseudorandom affine functions for encrypting color images

“…Ciphering images is the process of protecting them by altering their pixels in a way that makes them indecipherable. It protects image confidentiality and integrity, particularly when the images are sensitive and confidential, as is the military case [1] and medical images [2], [3]. Perturbations in ciphering steps complicate the statistical relationships between original and ciphered images and make predicting them difficult.…”
