Investigation and Implementation of Deep Learning Based Image Steganography
摘要
This study investigates the implementation of deep learning based neural networks for concealing images within other images also known as image steganography. While conventional techniques typically hide limited data in image pixel modifications, our work demonstrates how entire color photographs can be embedded within carrier images without noticeable visual changes. The research employs specialized convolutional neural network designs to achieve superior image recovery and visual indistinguishability. Experimental validation shows a Peak Signal-to-Noise Ratio of 43.2 dB alongside a Structural Similarity Index of 0.98, indicating virtually undetectable differences between original and modified images. This paper presents the network design, implementation algorithms, and comprehensive evaluation of our deep learning steganographic approach.
