This paper proposes an innovative method to enhance the security of color images by integrating hybrid cryptographic techniques, specifically using Sine maps and a double application of the logistic map. The proposed method encrypts a color image in several distinct phases. In the first phase, the image is converted into an M×N matrix. In addition, the Sine maps generate sequences for each color channel: red, green,…

In 1935, after more than a century of experimentation in Europe and America, a fully practical color-photography process for mass use was at last announced. Before that year, the practice of color photography had been limited to a relative handful of professionals and dedicated amateurs. But in the decades since the 1935 film was first marketed, the popularity of color photography has soared to the point where more …
