In this work, we show how to hide a maximum of 8 bits of secret data into the pixel difference value. Adjacent pixel pairs are chosen in a non-sequential manner in the spatial domain without using any seed or key. In spite of having high average embedding capacity and embedding efficiency, our algorithm can withstand visual, structural and statistical attacks. We compare our work with state-of-the-art works and also show that our work is capable of resisting the series of tests provided by the benchmark “StirMark”.

使用基于日历的消息编码的基于两点FFT的大容量图像隐写术

在这项工作中，我们展示了如何将最多8位的秘密数据隐藏到像素差值中。在空间域中以非顺序方式选择相邻像素对，而无需使用任何种子或键。尽管具有较高的平均嵌入容量和嵌入效率，但我们的算法仍可以抵抗视觉，结构和统计攻击。我们将我们的工作与最新技术进行了比较，还表明我们的工作能够抵御基准“ StirMark”提供的一系列测试。
