The continuous evolution of information technology underscores the growing emphasis on data security. In realm medical imaging, various diagnostic images represent privacy individuals, and potential repercussions their unauthorized disclosure are substantial. Therefore, this study introduces a novel chaotic system (TLCMCML) employs it to propose multi-image image encryption algorithm. To simultaneously augment security optimize efficiency, we undertake dual-pronged approach. Firstly, identify regions interest (ROIs) within individual images, subsequently applying an independent scrambling technique based odd-even interleaving configuration. Secondly, integrate all through horizontal concatenation, forming comprehensive large-scale image, upon which implement synchronized bit-level permutation-diffusion mechanism. Following extensive testing, enhancements were verified across metrics including entropy analysis, adjacent pixel correlation examination, differential attack simulations, robustness assessments, thereby attesting exceptional efficacy proposed

The rapid growth of digital data sharing has created a pressing need to safeguard the integrity, authenticity, and security bioanalytical images, such as Western blots, online. To address this challenge, we propose novel hybrid biometric watermarking technique that combines randomised singular value decomposition (RSVD), discrete wavelet transform (DWT), schur transform, pseudo magic cube, chaotic encryption, making blot images more secure, robust, imperceptible. Our approach surpasses state-of-the-art methods, ensuring imperceptible robust protection against tampering unauthorised use. By integrating spatial transform-domain techniques, achieve superior performance, outperforming existing methods with peak signal-to-noise ratio (PSNR) 48.7581, structural similarity index (SSIM) 0.9998, normalised correlation (NC) 0.9996, an average number changing pixel rate (NPCR) 0.9961, unified intensity (UACI) 0.3334. sets new standard for image in scientific research, addressing critical challenges tampering, copyright protection, security. With its high performance security, our enables trustworthy publication era.

Digital images have become an important way of transmitting information, and the risk attacks during transmission is increasing. Image watermarking technical means protecting image information security plays role in field security. In technology, achieving a balance between imperceptibility, robustness, embedding capacity key issue. To address this issue, paper proposes high-capacity color adaptive scheme based on discrete wavelet transform (DWT), Heisenberg decomposition (HD), singular value (SVD). order to enhance watermark, Logistic chaotic mapping was used encrypt watermark image. By adaptively calculating factor through entropy cover image, then combining it with Alpha blending embedded into Y component YCbCr space imperceptibility algorithm. addition, robustness algorithm further improved correction methods. The experimental results show that average PSNR SSIM are 45.3437dB 0.9987, respectively. When facing various attacks, NCC extracted reaches above 0.95, indicating good robustness. 0.6667bpp, which higher than other schemes, running time 1.1136 seconds, better most schemes.
