Abstract - In the current digital age, the widespread use of color images in areas like healthcare, surveillance, and multimedia communications has significantly increased concerns about image security. By incorporating a systematic approach following PRISMA guidelines, this paper presents a critical review of recent developments in cryptosystems used for color image encryption. Through a standardized examination of the state-of-the-art techniques, this review assesses techniques that ensure the authenticity, confidentiality, and integrity of color images. We focus on offering insights into current developments along with outlining potential directions for future research in the field of color image encryption. The vital aim of this study is to provide a comprehensive analysis of modern encryption algorithms, including chaotic maps, image scrambling, and hybrid techniques, and to evaluate their performance. The paper highlights the evolution of cryptographic methodologies for enhancing security, acceptance, and effectiveness in real-world applications.
