New algorithm achieves differential sensitivity in image permutation

Researchers have developed a new algorithm called Triangular Content-Aware Permutation (TCA) that challenges the long-held assumption that pixel permutation alone cannot achieve differential sensitivity in image processing. Unlike previous methods, TCA utilizes Canny edge detection and Delaunay Triangulation to create a unique partition that is highly sensitive to geometric changes. This sensitivity allows a single pixel alteration to result in a completely different global permutation pattern, significantly increasing the NPCR (Number of Pixel Change Rate) to 97.10%. While slower than traditional methods, TCA offers enhanced security for applications like reference-based encryption and fragile watermarking. AI

IMPACT Introduces a novel method for image encryption and data hiding with potential applications in secure watermarking and steganography.

    A Content-Aware Pure Permutation with Intrinsic Avalanche Effect: Breaking the Diffusion-Permutation Dichotomy

    arXiv:2608.09452v1 Announce Type: new Abstract: Pixel permutation is a fundamental tool in image processing, image encryption, and data hiding (including watermarking and steganography) that rearranges pixels without changing their values. A common assumption in the literature is…
