实施了用于在个人计算机（PC）上隐藏敏感文本数据的安全系统。该系统建议使用基于普通多媒体图像的隐写术，用要隐藏的文本替换像素最低有效位。该研究涉及多种测试场景，以提高隐写术的容量和模糊性，采用 1、2、3 和 4 个最低有效位隐写系统选择。设计新颖之处在于向用户提供完整的安全信息，以根据安全优先级从 PC 中选择适当的封面图像。该技术允许 PC 用户在多个图像上测试多位隐写术，以隐藏相同的敏感文本。然后，用户可以基于他知道所需的容量和安全优先级的选择来优选将一张图像用作封面图像。该研究通过对 35 个固定大小的 PC 图像进行实验，证明了数据依赖性及其安全性，结果显着。
Security system for hiding sensitive text-data on personal computer (PC) is implemented. The system proposes using normal multimedia image based steganography replacing the pixel least significant bits with text to be hidden. The study involved several testing scenarios for possible increase in the capacity and ambiguity within steganography adopting 1, 2, 3 and 4 least significant bits stego-systems choices. The design novelty is in providing full security information to the user to select appropriate cover-image from the PC based on the security priority. The technique allows the PC user to test multi-bits steganography on several images to hide same sensitive texts. Then, the user can prefer one image to be used as cover image based on his selection knowing the capacity and security priority desired. The study proofs the data dependency and its security property by experimenting 35 fixed sizes PC images showing remarkable results.
