摘要 This study proposes an image content protection method combining pseudorandom permutation and pixel diffusion. The approach first scrambles pixel positions using a pseudorandom permutation to conceal visual content without altering pixel values, thereby avoiding image quality degradation. A compact key serves as the basis for permutation, and the modulo operation is applied to compute new coordinates for each pixel, resulting in a highly disordered visual output. Subsequently, pixel diffusion is applied using the extended key to further encrypt pixel values, enhancing data security. During recovery, inverse operations with the identical key are used to decrypt pixel values and restore each pixel to its original position, ensuring lossless image reconstruction. Experimental results demonstrate that the proposed method achieves performance comparable to or better than the existing approaches across autocorrelation, structure similarity, and parameter sizes. These findings highlight the method's potential for secure visual access control and content protection applications, offering a lightweight yet effective solution for safeguarding sensitive image data while maintaining high visual fidelity.
