C. Sheeba Joice, Hitha Shanthini S, Harsha K, S Gopika · 2024
The necessity of secure image transmission and storage has become more urgent in the digital era. In a variety of applications, including medical imaging, military communications, and personal data protection, image encryption is essential for safeguarding sensitive visual data from unauthorized access and assuring privacy. This article offers a thorough examination of the current image encryption algorithms, with an emphasis on their strengths, weaknesses, and methodologies. Classical methods, such as symmetric and asymmetric encryption, as well as more sophisticated techniques, such as chaos-based, quantum-based, and hybrid encryption methods, are investigated. The objective of this review is to offer researchers and practitioners a valuable resource for comprehending the current state of image encryption and directing the development of more efficient and robust encryption solutions.
