Comprehensive Review and Analysis of an Image Processing Encryption Techniques

Abstract Image sharing across networks has grown rapidly with the expansion of cloud platforms and multimedia communication systems. Protecting sensitive image data from unauthorized access remains a major cybersecurity challenge. This paper presents a secure image data sharing framework that integrates Advanced Encryption Standard (AES) for high‑speed image encryption and Rivest–Shamir–Adleman (RSA) for secure key exchange. The proposed system uses role‑based access control with modules such as Admin, User, Client, Key Generation, and Server. Quantitative analysis including encryption time comparison, NPCR, UACI, and correlation metrics demonstrates strong resistance against statistical and differential attacks. Experimental results indicate that the AES–RSA hybrid model provides improved security while maintaining efficient processing performance.
