Aletheia is a command-line toolbox for detecting hidden messages in digital images. It uses machine learning and modern steganalysis techniques to examine JPEG and uncompressed image formats.
The software can identify content concealed using techniques and tools such as F5, Steghide, OutGuess, LSB replacement, LSB matching, nsF5 and J-UNIWARD. It is designed both for specialist analysts investigating suspicious images and researchers evaluating steganography and steganalysis methods.
This is free and open source software.
Key Features
- Automatically analyses images for evidence of hidden content.
- Supports JPEG and uncompressed image formats.
- Detects a range of traditional and adaptive steganography methods.
- Includes structural detectors for LSB replacement and related techniques.
- Provides calibration attacks and feature-extraction methods including SRM, GFR and DCTR.
- Includes simulators for numerous spatial-domain and JPEG steganography algorithms.
- Uses deep-learning models including SRNet and EfficientNet-B0.
- Supports model training, scoring and prediction workflows.
- Reports estimated probabilities and confidence values for detected steganographic content.
- Includes password brute-force tools for several steganography applications.
