A Novel Steganography Method for Character-Level Text Image Based on Adversarial Attacks

open access: yesSensors, 2022
The Internet has become the main channel of information communication, which contains a large amount of secret information. Although network communication provides a convenient channel for human communication, there is also a risk of information leakage.

Pit Stop for an Audio Steganography Algorithm [PDF]

open access: yes, 2013
Steganography plays an important role in the field of secret communication. The security of such communication lies in the impossibility of proving that secret communication is taking place.We evaluate the implementation of a previously published spread spectrum technique for steganography in auditive media.

A Secure Video Steganography Based on the Intra-Prediction Mode (IPM) for H264

open access: yesSensors, 2020
Recently, many video steganography algorithms based on the intra-prediction mode (IPM) have been adaptive steganography algorithms. These algorithms usually focus on the research about mapping rules and distortion functions while ignoring the fact that ...
