一种抗几何攻击的无载体图像隐写方法
A coverless image steganography method against geometric attacks
摘要
Abstract
To address the issues of poor security and difficulty in resisting geometric attacks during the transmission of steganographic images in existing algorithms,a coverless image steganography method resistant to geometric attacks was proposed.First,an EfficientNet model was used to construct a carrier image dataset based on the input images,and then the carrier images were divided into concentric circular blocks.The robust feature sequence was generated by calculating the color moments of the sub-blocks from the innermost circle outward.An inverted index was established based on the image feature values and image paths.Finally,the secret information was segmented according to the bit length of the image feature sequence,and an appropriate carrier image was selected for transmission based on the mapping rules.Experimental results show that this method enhances capacity while demonstrating robustness against both geometric and non-geometric attacks.关键词
