Steganography trace optimization method and device, electronic equipment and readable storage medium

The invention provides a steganography trace optimization method and device, electronic equipment and a readable storage medium, and the steganography trace optimization method based on an adversarial sample comprises the steps: adding secret information and distortion cost on the basis of a first carrier; performing steganography through the steganography code to obtain a second carrier; performing disturbance adding treatment on the second carrier; and introducing an iterative attack steganography post-processing model to carry out post-processing on the second carrier to obtain a third carrier. According to the embodiment of the invention, the steganography concealment is improved on the premise of ensuring secret letter embedding extraction. 本发明提供了一种隐写痕迹优化方法、装置、电子设备和可读存储介质，基于对抗样本的隐写痕迹优化方法包括：在第一载体的基础上，添加秘密信息和失真代价；通过隐写代码进行隐写，得到第二载体；对第二载体进行添加扰动的处理；引入迭代攻击隐写后处理模型对第二载体进行后处理，得到第三载体。本发明实施例保证密信嵌入提取的前提下提高隐写的隐蔽性。
