Protection Again Criminal uses of Steganography
Detection of hidden information in images and images generated using artificial intelligence.
Protection Again Criminal uses of Steganography
- Detect hidden information in images<br />- Understand the factors that make this detection difficult<br />- Characterize the signature of a natural photograph<br />- Use the proposed method, based on the signature of a photograph's acquisition chain, to identify images generated by artificial intelligence
We characterized the signature of the acquisition chain of a natural photograph based on the statistical distribution of noise in residual images.
- We characterized the correlation between neighboring pixels as a signature of the acquisition chain of a natural photograph.
- We exploited the correlation structure between pixels to measure the difficulty of detecting hidden information.
- We exploited the correlation structure between pixels to explain the source mismatch (distribution shift) problem in steganography.
- We exploited the correlation structure between pixels to identify images generated by artificial intelligence.
Work to characterize the correlation between pixels and the chain of acquisition of a natural photograph in order to detect images generated by artificial intelligence is still in its infancy. We will continue in this direction with a possible application to videos.

The present PACeS project focuses on steganography and steganalysis, i.e. data hiding within innocuous-like digital media. Such tools are readily available on the Internet and can be used by criminals rings, or for sensitive data leakage. Surprisingly, there is no software to detect this threat. This project aims essentially at developing such detection tools for filling this gap. Our method relies on accurate media statistical models for guaranteeing a very low false-positive rate and leveraging the design of adversarial methods, exploiting such models by hiding data while minimizing the detectability. PACeS project also addresses very operational issues by focusing on a context that is as realistic as possible. This includes, especially, addressing the problems related to the very high diversity of media as well as taking into account the increasing use of videos can be studied in steganography and steganalysis due to complete absence of exploitable statistical models.
