A Study on Access Control for Color Images Using Visual Information

随着通信渠道和终端的快速增长，可扩展传输已成为流行趋势。首先，我们开发了一种安全灵活的可扩展介质访问控制方案。接下来，我们还提出了一种基于颜色的访问控制方案，该方案通过对基于调色板的图像中的索引颜色进行排序。此外，我们提出的索引颜色排序方案已应用于基于调色板的图像的信息隐藏。

With the rapid growth in communication channels and terminals, scalable transmission has become popular. First, we have developed a secure and flexible access control scheme for scalable media. Next, we have also proposed a color-based access control scheme by sorting indexed colors in palette-based images. Furthermore, our proposed sorting scheme for indexed colors has applied to information hiding for palette-based images.
