Libpqstego is a library for perturbed quantization steganography to embed or extract secret messages in or from JPEG images. The implementation is based on J. Fridrich steganography algorithm as described in her paper "Perturbed quantization steganography with wet paper codes"

Created attachment 177984 [details] Perturbed Quantization Steganography Library Libpqstego is a library for perturbed quantization steganography with wet paper codes. Libpqstego uses the quantization step during JPEG-compressen to embed secret data into an image. The implemented algorithm is nearly undetectable by blind steganalysis and much more secure than outguess, F5 or MB2.
