Jsteg Algorithm Implementation for Information Hiding in JPEG Images

Implementation of the Jsteg algorithm for concealing information within JPEG images through subtle modifications to DCT coefficients.

Batch Jsteg Steganography for JPEG Images with Implementation Details

Jsteg_Mu enables batch Jsteg steganography processing for JPEG images. The tool operates with three main parameters: Jpeg_Or (folder containing original JPEG images), Jpeg_Di (output folder for steganographed images), code_file (payload file for embedding), and rate (embedding rate parameter controlling data hiding capacity). The implementation utilizes DCT coefficient modification while maintaining JPEG compatibility.

Steganalysis Resistant to Jsteg

Steganalysis resistant to Jsteg, one of the most important methods for JPEG image steganography, along with code implementation insights on detection algorithms.
