Abstract

The invention relates to a steganalysis method based on adversarial net. The method includes the following steps: A1. processing data in image data that is uploaded by a user, extracting to-be-determined steganalysis characteristics; A2. using a steganalysis mode generator of the adversarial net that is trained in advance to generate steganalysis data characteristics; A3. inputting the to-be-determined steganalysis characteristics and the generated steganalysis data characteristics to a determining machine of the adversarial net which is trained in advance, and comparing characteristics, on the basis of similarity from the comparison, identifying the type of the steganalysis mode of the image data that is uploaded. According to the invention, the method combines the adversarial net and the steganalysis, applies expandability, trainability, robustness and non-linear mapping capability of the adversarial net, and increases the precision and universality of steganalysis.

Description

technical field

[0001] The invention belongs to the technical field of information security, and in particular relates to a steganalysis method based on an adversarial neural network. Background technique

[0002] With the rise of mobile steganographic software, users can use many mobile steganographic software for real-time steganographic communication anytime and anywhere, such as ImghidAndReveal, MySecret, StegDroid under Android platform, SpyPix, StegoSec, InvisiLetter in IOS, etc. Steganographic communication has the characteristics of wide application, fast and strong concealment, which poses a great threat to network security.

[0003] Steganalysis is a reverse analysis method against steganography. Its purpose is to judge the existence of steganographic information. The key is to obtain the characteristic quantity that can reflect the change of data before and after steganography.

[0004] The general blind analysis method in the steganalysis method regards steganog...
