Steganography is the practice of hiding a message or information within another file, such as an image (Singh & Singla, 2022). OSINT (Open Source Intelligence) involves using publicly available for intelligence gathering purposes. In this research, asymmetric key algorithm will be applied to steganography method, 10 images with different sizes and dimensions. Images tested are in tiff, gif,...

In this paper, we propose a novel defensive transformation that enables us to maintain high classification accuracy under the use of both clean images and adversarial examples for adversarially robust defense. The proposed is block-wise preprocessing technique with secret key input images. defense obfuscates gradients in absence unlike previously defeated obfuscating defenses. We developed thre...
