A Survey on the Application of Chaos-Based Encryption Techniques on Medical Images

The security requirements for radiological images, which are now transferred across numerous networks, are very high. During this COVID-19 days, clinicians are solely dependent on these radiological images. Transmission of these medical records is becoming more common due to an increase in patients, and keeping them confidential, along with availability and integrity, emerges as one of the most crucial security considerations. Numerous algorithms are employed to safeguard data against unauthorized access since image data has a variety of properties. This paper focuses primarily on the specific cryptographic methods utilized for the image encryption and decryption of the COVID-19 medical image data within the field of information security. In addition, a comparative study is carried out among the parameters used to measure security of the existing literatures.
