LDH algorithms can embed information while maintain the integrity of the host media. It has wide applications in the fields of remote sensing, military and medicine image processing, where require high fidelity of image. However, these algorithms are designed on the assumption that their work environment is lossless, i.e. when the stego-image has a little distortion, the secret information cannot be correctly extracted. For this reason, some scholars put forward the concept of the Robust LDH (RLDH), whose goal is the secret information can be correctly extracted in lossless and lossy environment.
