Abstract: With the rapid advancement of digital technologies, multimedia content such as images has become increasingly accessible and widely distributed. However, this growth has also raised significant concerns regarding the security and privacy of data during transmission and storage. In today’s multimedia-driven world, images play a pivotal role in sectors like business, marketing, and digital promotions. Consequently, protecting image data from unauthorized access is of paramount importance. Image encryption serves as a crucial tool in the domain of information hiding. This article presents an enhanced chaos-based image encryption method that utilizes a 128-bit symmetric key for robust security. The effectiveness of the proposed encryption approach is evaluated using JDK1.7 and benchmarked against existing techniques. Experimental results demonstrate that the proposed scheme achieves higher entropy in the encrypted images, indicating improved security performance over traditional methods.
