A scheme of hiding large-size image into small-size image based on FCdDNet [PDF]
PeerJ Computer ScienceThe hiding capacity of the current information hiding field has reached a relatively high level, which can hide two color images into one color image. In order to explore a larger hidden capacity, an information hiding scheme based on an improved FCdDNet

Large-capacity information hiding scheme based on minimum pixel modification
Egyptian Informatics Journal, 2022 Information hiding is an important technique for security-related applications, and it can be used wildly in many scenarios. Secret data embedding methods are proposed in spatial, frequency, and other domains by researchers in recent years.

Genre-Based Information Hiding [PDF]
, 2012 While data encryption is an effective means of keeping data private it does not conceal the presence of 'hidden' information, rather it serves as an indicator that such data is present. Concealing information and hiding the fact that information is hidden are both desirable traits of a confidential data exchange, especially if that exchange takes place

Compositional Methods for Information-Hiding [PDF]
Mathematical Structures in Computer Science, 2008 Systems concerned with information hiding often use randomization to obfuscate the link between the observables and the information to be protected. The degree of protection provided by a system can be expressed in terms of the probability of error associated with the inference of the secret information.
