基于DCT域的数字图像隐写术分析
DCT-based Digital Image Steganography Analysis
摘要
Abstract
Steganography plays a vital role in the security of multimedia communication. For digital image steganography based on DCT domain,the steganographic effects of secret information in mother and Lena image are simulated,the impact on image quality is studied with different embedded positions of the secret information in the DCT domain of an image, as well as with different carrier images. Studies show that: embedding the information in the low frequency part of the image and selecting the image with rich distribution pixel value can help improve the steganography effects of the information in the image and enhance the concealment of the secret information.关键词
