Abstract

Steganography deals with hiding information, which offers ultimate security in defense, profitable usages, thus sending the imperceptible information, will not be bare or distinguished by others. In this paper, a multidirectional PVD hiding scheme with RSA algorithm is proposed. Secret bits are embedded in three directions of a color image by dividing the non-overlapping blocks into R, G, b channels by selecting the minimum pixels of each block regrouping. In order to ensure the security of an stego-image, the work proposed by scheme is used, and in addition to that RSA algorithm is proposed.

使用 PVD ​​隐藏数据并使用 RSA 提高安全性

摘要

隐写术处理隐藏信息，它在防御、有利可图的用途中提供终极安全性，因此发送不易察觉的信息，不会被其他人暴露或区分。本文提出了一种基于RSA算法的多向PVD隐藏方案。通过选择每个块重组的最小像素，将不重叠的块划分为 R、G、b 通道，将秘密比特嵌入彩色图像的三个方向。为了保证隐写图像的安全性，使用了方案提出的工作，此外还提出了RSA算法。
