Double Security Level Protection Based on Chaotic Maps and SVD for Medical Images

Mathematics, Год журнала: 2025, Номер 13(2), С. 182 - 182

Опубликована: Янв. 8, 2025

The widespread distribution of medical images in smart healthcare systems will cause privacy concerns. unauthorized sharing decrypted remains uncontrollable, though image encryption can discourage disclosure. This research proposes a double-level security scheme for to overcome this problem. proposed joint and watermarking is based on singular-value decomposition (SVD) chaotic maps. First, three different random sequences are used encrypt the LL subband discrete wavelet transform (DWT) domain; then, HL LH sub-bands embedded with watermark information; end, we obtain watermarked encrypted inverse DWT (IDWT) transform. In study, SVD domain. main originality that decryption extraction be performed separately. Experimental results demonstrate superiority method key spaces (10225), PSNR (76.2543), UACI (0.3329). implementation, following achievements attained. our meet requests levels. Second, Third, detected Thus, experiment analysis effectiveness scheme.

Image encryption scheme based on thorp shuffle and pseudo dequeue

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Апрель 1, 2025

To enhance the security level of image data transmission, this paper proposes a four-dimensional hyperchaotic encryption scheme based on combination Thorp shuffle and pseudo dequeue. First, nonlinear term classic Chen chaotic system is improved to construct an system. Phase diagrams, Lyapunov exponents, equilibrium points are used analyze its dynamic characteristics. The has rich behaviors, maximum exponent reaches 11.3. Second, SHA-256 algorithm in with plain information generate initial key. On basis key, pseudorandom sequence generated by for scrambling diffusion operations. An combined sequences subsequently designed, which includes index scrambling, double-ended shuffle, step multiplane bit operation. Finally, performance evaluated through experiments such as statistical analysis, differential attack noise analysis. entropy cipher can reach 7.9994, number pixel change rates unified average intensity being close ideal value, percentage floating frequency 63%. results show that proposed high efficiency performs excellently terms anti-attack performance.
