Iqra Hussain, Samarjeet Khanna · International Academic Journal of Science and Engineering · 2025
In recent years, image encryption, a critical domain of data security, has garnered considerable attention from researchers and scientists. Numerous studies have proposed innovative and effective methods to enhance secure picture encryption systems. Chaotic methodologies have been identified in multiple domains, including cryptosystem design and picture encryption. Digital picture encryptions using chaotic algorithms represent a fresh approach to image security. This technology employs random chaotic sequences for image encryption, providing a very secure and rapid way. This approach has limited precision as a drawback. This work investigates the chaotic sequence and the wavelet transform values to identify gaps. A fresh method for digital image encryption has been suggested, enhancing prior algorithms. The technique is executed in MATLAB, and a comparison is conducted based on several performance metrics, including the Number of Pixels Change Rates (NPCR), Peak Signal to Noise Rate (PSNR), correlation factor, and Unified Average Changing Illumination (UACI). The modeling and mathematical evaluation demonstrate the suggested scheme's efficacy, confirming that this technology is an appropriate option for the practical encryption of images.
